Therapy is supportive and includes removal from further beryllium exposure. For very severe cases mechanical ventilation may be required.

Treatment of mild metal fume fever consists of bedrest, keeping the patient well hydrated, and symptomatic therapy (e.g. aspirin for headaches) as indicated. In the case of non-allergic acute lung injury, standard or recommended approaches to treatment have not been defined.

The consumption of large quantities of cow's milk, either before or immediately after exposure is a traditional remedy. However, the United Kingdom Health and Safety Executive challenges this advice, warning, "Don’t believe the stories about drinking milk before welding. It does not prevent you getting metal fume fever."

There is no cure for berylliosis; the goals of treatment are to reduce symptoms and slow the progression of disease.

Although the evidence that stopping exposure to beryllium decreases progression of the disease, it is still considered to be an accepted approach to treatment in any stage of disease.

People with early stages of disease, without lung function abnormalities or clinical symptoms, are periodically monitored with physical exams, pulmonary function testing and radiography.

Once clinical symptoms or significant abnormalities in pulmonary function testing appear, treatments include oxygen and oral corticosteroids and whatever supportive therapy is required.

Prevention of metal fume fever in workers who are at risk (such as welders) involves avoidance of direct contact with potentially toxic fumes, improved engineering controls (exhaust ventilation systems), personal protective equipment (respirators), and education of workers regarding the features of the syndrome itself and proactive measures to prevent its development.

In some cases, the product's design may be changed so as to eliminate the use of risky metals. NiCd rechargeable batteries are being replaced by NiMH. These contain other toxic metals, such as chromium, vanadium and cerium. Cadmium is often replaced by other metals. Zinc or nickel plating can be used instead of cadmium plating, and brazing filler alloys now rarely contain cadmium.

Silicosis is a permanent disease with no cure. Treatment options currently available focus on alleviating the symptoms and preventing any further progress of the condition. These include:

- Stopping further exposure to airborne silica, silica dust and other lung irritants, including tobacco smoking.

- Cough suppressants.

- Antibiotics for bacterial lung infection.

- TB prophylaxis for those with positive tuberculin skin test or IGRA blood test.

- Prolonged anti-tuberculosis (multi-drug regimen) for those with active TB.

- Chest physiotherapy to help the bronchial drainage of mucus.

- Oxygen administration to treat hypoxemia, if present.

- Bronchodilators to facilitate breathing.

- Lung transplantation to replace the damaged lung tissue is the most effective treatment, but is associated with severe risks of its own.

- For acute silicosis, bronchoalveolar lavage may alleviate symptoms, but does not decrease overall mortality.

Experimental treatments include:

- Inhalation of powdered aluminium, d-penicillamine and polyvinyl pyridine-N-oxide.

- Corticosteroid therapy.

- Chinese Herbal Kombucha

- The herbal extract tetrandrine may slow progression of silicosis.

Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. Chelating agents are molecules that have multiple electron-donating groups, which can form stable coordination complexes with metal ions. Complexation prevents the metal ions from reacting with molecules in the body, and enable them to be dissolved in blood and eliminated in urine. It should only be used in people who have a diagnosis of metal intoxication. That diagnosis should be validated with tests done in appropriate biological samples.

Chelation therapy is administered under very careful medical supervision due to various inherent risks. When the therapy is administered properly, the chelation drugs have significant side effects. Chelation administered inappropriately can cause neurodevelopmental toxicity, increase risk of developing cancer, and cause death; chelation also removes essential metal elements and requires measures to prevent their loss.

The mainstays of treatment are removal from the source of lead and, for people who have significantly high blood lead levels or who have symptoms of poisoning, chelation therapy. Treatment of iron, calcium, and zinc deficiencies, which are associated with increased lead absorption, is another part of treatment for lead poisoning. When lead-containing materials are present in the gastrointestinal tract (as evidenced by abdominal X-rays), whole bowel irrigation, cathartics, endoscopy, or even surgical removal may be used to eliminate it from the gut and prevent further exposure. Lead-containing bullets and shrapnel may also present a threat of further exposure and may need to be surgically removed if they are in or near fluid-filled or synovial spaces. If lead encephalopathy is present, anticonvulsants may be given to control seizures, and treatments to control swelling of the brain include corticosteroids and mannitol. Treatment of organic lead poisoning involves removing the lead compound from the skin, preventing further exposure, treating seizures, and possibly chelation therapy for people with high blood lead concentrations.

A chelating agent is a molecule with at least two negatively charged groups that allow it to form complexes with metal ions with multiple positive charges, such as lead. The chelate that is thus formed is nontoxic and can be excreted in the urine, initially at up to 50 times the normal rate. The chelating agents used for treatment of lead poisoning are edetate disodium calcium (CaNaEDTA), dimercaprol (BAL), which are injected, and succimer and d-penicillamine, which are administered orally.

Chelation therapy is used in cases of acute lead poisoning, severe poisoning, and encephalopathy, and is considered for people with blood lead levels above 25 µg/dL. While the use of chelation for people with symptoms of lead poisoning is widely supported, use in asymptomatic people with high blood lead levels is more controversial. Chelation therapy is of limited value for cases of chronic exposure to low levels of lead. Chelation therapy is usually stopped when symptoms resolve or when blood lead levels return to premorbid levels. When lead exposure has taken place over a long period, blood lead levels may rise after chelation is stopped because lead is leached into blood from stores in the bone; thus repeated treatments are often necessary.

People receiving dimercaprol need to be assessed for peanut allergies since the commercial formulation contains peanut oil. Calcium EDTA is also effective if administered four hours after the administration of dimercaprol. Administering dimercaprol, DMSA (Succimer), or DMPS prior to calcium EDTA is necessary to prevent the redistribution of lead into the central nervous system. Dimercaprol used alone may also redistribute lead to the brain and testes. An adverse side effect of calcium EDTA is renal toxicity. Succimer (DMSA) is the preferred agent in mild to moderate lead poisoning cases. This may be the case in instances where children have a blood lead level >25μg/dL. The most reported adverse side effect for succimer is gastrointestinal disturbances. It is also important to note that chelation therapy only lowers blood lead levels and may not prevent the lead-induced cognitive problems associated with lower lead levels in tissue. This may be because of the inability of these agents to remove sufficient amounts of lead from tissue or inability to reverse preexisting damage.

Chelating agents can have adverse effects; for example, chelation therapy can lower the body's levels of necessary nutrients like zinc. Chelating agents taken orally can increase the body's absorption of lead through the intestine.

Chelation challenge, also known as provocation testing, is used to indicate an elevated and mobilizable body burden of heavy metals including lead. This testing involves collecting urine before and after administering a one-off dose of chelating agent to mobilize heavy metals into the urine. Then urine is analyzed by a laboratory for levels of heavy metals; from this analysis overall body burden is inferred. Chelation challenge mainly measures the burden of lead in soft tissues, though whether it accurately reflects long-term exposure or the amount of lead stored in bone remains controversial. Although the technique has been used to determine whether chelation therapy is indicated and to diagnose heavy metal exposure, some evidence does not support these uses as blood levels after chelation are not comparable to the reference range typically used to diagnose heavy metal poisoning. The single chelation dose could also redistribute the heavy metals to more sensitive areas such as central nervous system tissue.

Acute beryllium poisoning is an occupational disease. Relevant occupations are those where beryllium is mined, processed or converted into metal alloys, or where machining of metals containing beryllium or recycling of scrap alloys occurs.

Beryllium is regarded extraordinarily hazardous to health upon enough amounts of dust, mists, or fumes consisting fragments little enough to inhale (typically 10µm or less). Metallographic preparation equipment and laboratory work surfaces must be damp wiped occasionally to inhibit buildup of particles. Cutting, grinding, and polishing procedures which manufacture dusts or fumes must be handled within sufficiently vented coverings supplied with particular filters.

Typical levels of beryllium that industries may release into the air are of the order of , averaged over a 30-day period, or of workroom air for an 8-hour work shift. Compliance with the current U.S. Occupational Safety and Health Administration (OSHA) permissible exposure limit for beryllium of has been determined to be inadequate to protect workers from developing beryllium sensitization and CBD. The American Conference of Governmental Industrial Hygienists (ACGIH), which is an independent organization of experts in the field of occupational health, has proposed a threshold limit value (TLV) of in a 2006 Notice of Intended Change (NIC). This TLV is 40 times lower than the current OSHA permissible exposure limit, reflecting the ACGIH analysis of best available peer-reviewed research data concerning how little airborne beryllium is required to cause sensitization and CBD.

Because it can be difficult to control industrial exposures to beryllium, it is advisable to use any methods possible to reduce airborne and surface contamination by beryllium, to minimize the use of beryllium and beryllium-containing alloys whenever possible, and to educate people about the potential hazards if they are likely to encounter beryllium dust or fumes. It is important to damp wipe meallographic preparation equipment to prevent accumulation of dry particles. Sectioning, grinding, and polishing must be performed under sufficiently vented hoods equipped with special filters.

On 29 January 2009, the Los Alamos National Laboratory announced it was notifying nearly 2,000 current and former employees and visitors that they may have been exposed to beryllium in the lab and may be at risk of disease. Concern over possible exposure to the material was first raised in November 2008, when a box containing beryllium was received at the laboratory's short-term storage facility.

Short-acting beta-agonists like salbutamol or terbutaline or long-acting beta-agonists like salmeterol and formoterol dilate airways which relieve the symptoms thus reducing the severity of the reaction. Some patients also use it just before work to avoid a drop in the FEV.

Anti-inflammatory agents like corticosteroids, LKTRA or mast cell stabilizers can also be used depending on the severity of the case.

It is difficult to differentiate the effects of low level metal poisoning from the environment with other kinds of environmental harms, including nonmetal pollution. Generally, increased exposure to heavy metals in the environment increases risk of developing cancer.

Without a diagnosis of metal toxicity and outside of evidence-based medicine, but perhaps because of worry about metal toxicity, some people seek chelation therapy to treat autism, cardiovascular disease, Alzheimer's disease, or any sort of neurodegeneration. Chelation therapy does not improve outcomes for those diseases.

Depending on the severity of the symptoms, FLD can last from one to to weeks, or they can last for the rest of one’s life. Acute FLD has the ability to be treated because hypersensitivity to the antigens has not yet developed. The main treatment is rest and reducing the exposure to the antigens through masks and increased airflow in confined spaces where the antigens are present. Another treatment for acute FLD is pure oxygen therapy. For chronic FLD, there is no true treatment because the patient has developed hypersensitivity meaning their FLD could last the rest of their life. Any exposure to the antigens once hypersensitivity can set off another chronic reaction.

The only prevention for FLD is ventilating the work areas putting workers at risk and using face masks to filter out the antigens attempting to enter the lungs through the air.

Recovery is directly dependent on the duration and level of exposure to the causative agent. Depending on the severity of the case, the condition of the patient can improve dramatically during the first year after removal from exposure.

Three basic types of procedures are used for treating the affected workers: reducing a worker's exposure, removing a worker from the environment with the asthma-causing agent, and treatment with asthma medications. Completely stopping exposure is more effective treatment than reducing exposure. By reducing exposure, the probability of suffering another reaction is lowered. Methods of reducing exposure include transferring an affected worker to a position without the relevant asthmagen, use of respiratory protection, and engineering controls. In 1984 innovator David Cornell discovered and invented effective control equipment in the UK for the removal of many harmful workplace fumes. 'BOFA' extraction products are now found in over 100 countries worldwide.

People affected by occupational asthma that occurred after a latency period, whether a few months or years, should be immediately removed from exposure to the causative agent. However, this can entail severe socio-economic consequences for the worker as well as the employer due to loss of job, unemployment, compensation issues, quasi-permanent medical expenditures, and hiring and re-training of new personnel. This can be mitigated by transferring the worker within a company.

The best way to prevent silicosis is to identify work-place activities that produce respirable crystalline silica dust and then to eliminate or control the dust ("primary prevention"). Water spray is often used where dust emanates. Dust can also be controlled through dry air filtering.

Following observations on industry workers in Lucknow (India), experiments on rats found that jaggery (a traditional sugar) had a preventive action against silicosis.

Cadmium is a naturally occurring toxic heavy metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure to humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure. Cadmium is also found in some industrial paints and may represent a hazard when sprayed. Operations involving removal of cadmium paints by scraping or blasting may pose a significant hazard. Cadmium is also present in the manufacturing of some types of batteries. Exposures to cadmium are addressed in specific standards for the general industry, shipyard employment, construction industry, and the agricultural industry.

Chronic exposure to human nail dust is a serious occupational hazard that can be minimized by not producing such dust. Best practice is to avoid electrical debridement or burring of mycotic nails unless the treatment is necessary. When the procedure is necessary, it is possible to reduce exposure by using nail dust extractors, local exhaust, good housekeeping techniques, personal protective equipment such as gloves, glasses or goggles, face shields, and an appropriately fitted disposable respirators to protect against the hazards of nail dust and flying debris.

Although feline asthma is incurable, ongoing treatments allow many domestic cats to live normal lives. Feline asthma is commonly managed through use of bronchodilators for mild cases, or glucocorticosteroids with bronchodilators for moderate to severe cases.

Previously, standard veterinary practice recommended injected and oral medications for control of the disease. These drugs may have systemic side effects including diabetes and pancreatitis. In 2000, Dr. Philip Padrid pioneered inhaled medications using a pediatric chamber and mask using Flovent(r) (fluticasone) and salbutamol. Inhaled treatments reduce or eliminate systemic effects. In 2003 a chamber called the AeroKat Feline Aerosol Chamber was designed specifically for cats, significantly improving efficiency and reducing cost for the caregiver. Medicine can also be administered using a human baby spacer device. Inhaled steroid usually takes 10-14 days to reach an effective dose.

There have been numerous accounts of patients with "trichophyton" fungal infections and associated asthma, which further substantiates the likelihood of respiratory disease transmission to the healthcare provider being exposed to the microbe-laden nail dust In 1975, a dermatophyte fungal infection was described in a patient with severe tinea. The resulting treatment for mycosis improved the patient’s asthmatic condition. The antifungal treatment of many other "trichophyton" foot infections has alleviated symptoms of hypersensitivity, asthma, and rhinitis.

Coal ash, also known as coal combustion residuals (CCRs), is the particulate residue that remains from burning coal. Depending on the chemical composition of the coal burned, this residue may contain toxic substances and pose a health risk to workers in coal-fired power plants.

In humans, heavy metal poisoning is generally treated by the administration of chelating agents.

These are chemical compounds, such as (calcium disodium ethylenediaminetetraacetate) that convert heavy metals to chemically inert forms that can be excreted without further interaction with the body. Chelates are not without side effects and can also remove beneficial metals from the body. Vitamin and mineral supplements are sometimes co-administered for this reason.

Soils contaminated by heavy metals can be remediated by one or more of the following technologies: isolation; immobilization; toxicity reduction; physical separation; or extraction. "Isolation" involves the use of caps, membranes or below-ground barriers in an attempt to quarantine the contaminated soil. "Immobilization" aims to alter the properties of the soil so as to hinder the mobility of the heavy contaminants. "Toxicity reduction" attempts to oxidise or reduce the toxic heavy metal ions, via chemical or biological means into less toxic or mobile forms. "Physical separation" involves the removal of the contaminated soil and the separation of the metal contaminants by mechanical means. "Extraction" is an on or off-site process that uses chemicals, high-temperature volatization, or electrolysis to extract contaminants from soils. The process or processes used will vary according to contaminant and the characteristics of the site.

In most cases, lead poisoning is preventable by avoiding exposure to lead. Prevention strategies can be divided into individual (measures taken by a family), preventive medicine (identifying and intervening with high-risk individuals), and public health (reducing risk on a population level).

Recommended steps by individuals to reduce the blood lead levels of children include increasing their frequency of hand washing and their intake of calcium and iron, discouraging them from putting their hands to their mouths, vacuuming frequently, and eliminating the presence of lead-containing objects such as blinds and jewellery in the house. In houses with lead pipes or plumbing solder, these can be replaced. Less permanent but cheaper methods include running water in the morning to flush out the most contaminated water, or adjusting the water's chemistry to prevent corrosion of pipes. Lead testing kits are commercially available for detecting the presence of lead in the household. As hot water is more likely than cold water to contain higher amounts of lead, use only cold water from the tap for drinking, cooking, and for making baby formula. Since most of the lead in household water usually comes from plumbing in the house and not from the local water supply, using cold water can avoid lead exposure. Measures such as dust control and household education do not appear to be effective in changing children's blood levels.

Screening is an important method in preventive medicine strategies. Screening programs exist to test the blood of children at high risk for lead exposure, such as those who live near lead-related industries.

Prevention measures also exist on national and municipal levels. Recommendations by health professionals for lowering childhood exposures include banning the use of lead where it is not essential and strengthening regulations that limit the amount of lead in soil, water, air, household dust, and products. Regulations exist to limit the amount of lead in paint; for example, a 1978 law in the US restricted the lead in paint for residences, furniture, and toys to 0.06% or less. In October 2008, the US Environmental Protection Agency reduced the allowable lead level by a factor of ten to 0.15 micrograms per cubic meter of air, giving states five years to comply with the standards. The European Union's Restriction of Hazardous Substances Directive limits amounts of lead and other toxic substances in electronics and electrical equipment. In some places, remediation programs exist to reduce the presence of lead when it is found to be high, for example in drinking water. As a more radical solution, entire towns located near former lead mines have been "closed" by the government, and the population resettled elsewhere, as was the case with Picher, Oklahoma in 2009.

In cases of suspected copper poisoning, penicillamine is the drug of choice, and dimercaprol, a heavy metal chelating agent, is often administered. Vinegar is not recommended to be given, as it assists in solubilizing insoluble copper salts. The inflammatory symptoms are to be treated on general principles, as are the nervous ones.

There is some evidence that alpha-lipoic acid (ALA) may work as a milder chelator of tissue-bound copper. Alpha lipoic acid is also being researched for chelating other heavy metals, such as mercury.

Radon has been produced commercially for use in radiation therapy, but for the most part has been replaced by radionuclides made in accelerators and nuclear reactors. Radon has been used in implantable seeds, made of gold or glass, primarily used to treat cancers.

The gold seeds were produced by filling a long tube with radon pumped from a radium source, the tube being then divided into short sections by crimping and cutting. The gold layer keeps the radon within, and filters out the alpha and beta radiations, while allowing the gamma rays to escape (which kill the diseased tissue). The activities might range from 0.05 to 5 millicuries per seed (2 to 200 MBq). The gamma rays are produced by radon and the first short-lived elements of its decay chain (Po, Pb, Bi, Po).

Radon and its first decay products being very short-lived, the seed is left in place. After 12 half-lives (43 days), radon radioactivity is at 1/2000 of its original level. At this stage, the predominant residual activity is due to the radon decay product Pb, whose half-life (22.3 year) is 2000 times that of radon (and whose activity is thus 1/2000 or radon's), and its descendants Bi and Po, totalizing 0.03% of the initial seed activity.

A toxic heavy metal is any relatively dense metal or metalloid that is noted for its potential toxicity, especially in environmental contexts. The term has particular application to cadmium, mercury, lead and arsenic, all of which appear in the World Health Organisation's list of 10 chemicals of major public concern. Other examples include manganese, chromium, cobalt, nickel, copper, zinc, selenium, silver, antimony and thallium.

Heavy metals are found naturally in the earth. They become concentrated as a result of human caused activities and can enter plant, animal, and human tissues via inhalation, diet, and manual handling. Then, they can bind to and interfere with the functioning of vital cellular components. The toxic effects of arsenic, mercury, and lead were known to the ancients, but methodical studies of the toxicity of some heavy metals appear to date from only 1868. In humans, heavy metal poisoning is generally treated by the administration of chelating agents. Some elements otherwise regarded as toxic heavy metals are essential, in small quantities, for human health.
