Smoking has a supra-additive effect in increasing the risk of lung cancer in those exposed to asbestos. Studies have shown an increased risk of lung cancer among smokers who are exposed to asbestos compared to nonsmokers.

Diseases commonly associated with asbestos include:

- Asbestosis: Progressive fibrosis of the lungs of varying severity, progressing to bilateral fibrosis, honeycombing of the lungs on radiological view with symptoms including rales and wheezing. Individuals who have been exposed to asbestos via home, environment, work should notify their doctors about exposure history.

- Asbestos warts: caused when the sharp fibers lodge in the skin and are overgrown causing benign callus-like growths.

- Pleural plaques: discrete fibrous or partially calcified thickened area which can be seen on X-rays of individuals exposed to asbestos. Although pleural plaques are themselves asymptomatic, in some patients this develops into pleural thickening.

- Diffuse pleural thickening: similar to above and can sometimes be associated with asbestosis. Usually no symptoms shown but if exposure is extensive, it can cause lung impairment.

- Pneumothorax: Some reports have also linked the condition of pneumothorax to asbestos related diseases.

It is important to consult a doctor, particularly if the following symptoms develop: shortness of breath, wheezing or hoarseness, persistent cough that worsens over time, blood in fluid coughed up, pain or tightening in chest, difficulty swallowing, swelling of neck or face, decreased appetite, weight loss, fatigue or anemia.

Tobacco smoke is a known carcinogen. Workers in the hospitality industry may be exposed to tobacco smoke in the workplace, especially in environments like casinos and bars/restaurants.

Health care professionals are at risk of occupational influenza exposure; during a pandemic influenza, anyone in a close environment is at risk, including those in an office environment.

Lead: The exposure of lead in coal ash can cause major damage to the nervous system. Lead exposure can lead to kidney disease, hearing impairment, high blood pressure, delays in development, swelling of the brain, hemoglobin damage, and male reproductive problems. Both low levels and high levels of lead exposure can cause harm to the human body.

Cadmium: When coal ash dust is inhaled, high levels of cadmium is absorbed into the body. More specifically, the lungs directly absorb cadmium into the bloodstream. When humans are exposed to cadmium over a long period of time, kidney disease and lung disease can occur. In addition, cadmium exposure can be associated with hypertension. Lastly, chronic exposure of cadmium can cause bone weakness which increases the risk of bone fractures and osteoporosis.

Chromium: The exposure of chromium (IV) in coal ash can cause lung cancer and asthma when inhaled. When coal ash waste pollutes drinking water, chromium (IV) can cause ulcers in the small intestine and stomach when ingested. Lastly, skin ulcers can also occur when the exposure chromium (IV) in coal ash comes in contact with the skin.

Arsenic: When high amounts of arsenic is inhaled or ingested through coal ash waste, diseases such as bladder cancer, skin cancer, kidney cancer and lung cancer can develop. Ultimately, exposure of arsenic over a long period of time can cause mortality. Furthermore, low levels of arsenic exposure can cause irregular heartbeats, nausea, diarrhea, vomiting, peripheral neuropathy and vision impairment.

Mercury: Chronic exposure of mercury from coal ash can cause harm to the nervous system. When mercury is inhaled or ingested various health effects can occur such as vision impairment, seizures, numbness, memory loss and sleeplessness.

Boron: When coal ash dust is inhaled, the exposure of boron can cause discomfort in the throat, nose and eye. Moreover, when coal ash waste is ingested, boron exposure can be associated with kidney, liver, brain, and intestine impairment.

Molybdenum: When molybdenum is inhaled from coal ash dust, discomfort of the nose, throat, skin and eye can occur. As a result, short-term molybdenum exposure can cause an increase of wheezing and coughing. Furthermore, chronic exposure of molybdenum can cause loss of appetite, tiredness, headaches and muscle soreness.

Thallium: The exposure of thallium in coal ash dust can cause peripheral neuropathy when inhaled. Furthermore, when coal ash is ingested, thallium exposure can cause diarrhea and vomiting. In addition, thallium exposure is also associated with heart, liver, lung and kidney complications.

Silica: When silica is inhaled from coal ash dust, fetal lung disease or silicosis can develop. Furthermore, chronic exposure of silica can cause lung cancer. In addition, exposure to silica over a period of time can cause loss of appetite, poor oxygen circulation, breathing complications and fever.

Asbestos can cause lung cancer that is identical to lung cancer from other causes. Exposure to asbestos is associated with all major histological types of lung carcinoma (adenocarcinoma, squamous cell carcinoma, large-cell carcinoma and small-cell carcinoma). The latency period between exposure and development of lung cancer is 20 to 30 years. It is estimated that 3%-8% of all lung cancers are related to asbestos. The risk of developing lung cancer depends on the level, duration, and frequency of asbestos exposure (cumulative exposure). Smoking and individual susceptibility are other contributing factors towards lung cancer. Smokers who have been exposed to asbestos are at far greater risk of lung cancer. Smoking and asbestos exposure have a multiplicative (synergistic) effect on the risk of lung cancer. Symptoms include chronic cough, chest pain, breathlessness, haemoptysis (coughing up blood), wheezing or hoarseness of the voice, weight loss and fatigue. Treatment involves surgical removal of the cancer, chemotherapy, radiotherapy, or a combination of these (multimodality treatment). Prognosis is generally poor unless the cancer is detected in its early stages. Out of all patients diagnosed with lung cancer, only 15% survive for five years after diagnosis.

Pharmaceutical injuries can occur when a person is injured by a dangerous, defective or contaminated medication. Many pharmaceutical toxic injury cases are mass tort cases, as most medications are consumed by thousands of people. The cases are often litigated against drug manufacturers and distributors, and potentially against prescribing physicians. When prosecuted against drug manufacturers and distributors, pharmaceutical toxic tort cases differ from medical malpractice suits in that pharmaceutical toxic tort cases are essentially product liability cases, the defective product being the drug.

The home has recently become the subject of toxic tort litigation, due to exposure to mold contamination, construction materials such as wood or carpeting treated with formaldehyde, and pesticides, and lead paint. Some imported consumer items, such as toys and ceramics, may be produced with dangerously high levels of lead.

A 2015 SBU-report including a systematic review of non-chemical riskfactors for occupation cardiovascular disease found an association between certain occupational risk factors and developing cardiovascular disease in those:

- With mentally stressfull work with a lack of control of their own working situation — with a effort-reward imbalance

- Who experience low social support at work; who experience injustice or experience insufficient opportunities for personal development; or those who experience job insecurity

- Those who work night schedules; or have long working weeks

- Those who are exposed to noise

Specifically the risk of stroke was also increased by:

- Exposure to ionizing radiation

Hypertension develops more often in those who experience job strain and who have shift-work. Differences between women and men in risk are small, however men risk suffering and dieing of heart attacks or stroke twice as often as women during working life.

Occupational skin diseases are ranked among the top five occupational diseases in many countries.

Occupational skin diseases and conditions are generally caused by chemicals and having wet hands for long periods while at work. Eczema is by far the most common, but urticaria, sunburn and skin cancer are also of concern.

Contact dermatitis due to irritation is inflammation of the skin which results from a contact with an irritant. It has been observed that this type of dermatitis does not require prior sensitization of the immune system. There have been studies to support that past or present atopic dermatitis is a risk factor for this type of dermatitis. Common irritants include detergents, acids, alkalies, oils, organic solvents and reducing agents.

The acute form of this dermatitis develops on exposure of the skin to a strong irritant or caustic chemical. This exposure can occur as a result of accident at a workplace. The irritant reaction starts to increase in its intensity within minutes to hours of exposure to the irritant and reaches its peak quickly. After the reaction has reached its peak level, it starts to heal. This process is known as decrescendo phenomenon. The most frequent potent irritants leading to this type of dermatitis are acids and alkaline solutions. The symptoms include redness and swelling of the skin along with the formation of blisters.

The chronic form occurs as a result of repeated exposure of the skin to weak irritants over long periods of time.

Clinical manifestations of the contact dermatitis are also modified by external factors such as environmental factors (mechanical pressure, temperature, and humidity) and predisposing characteristics of the individual (age, sex, ethnic origin, preexisting skin disease, atopic skin diathesis, and anatomic region exposed.

Another occupational skin disease is Glove related hand urticaria. It has been reported as an occupational problem among the health care workers. This type of hand urticaria is believed to be caused by repeated wearing and removal of the gloves. The reaction is caused by the latex or the nitrile present in the gloves.

High-risk occupations include:

- Hairdressing

- Catering

- Healthcare

- Printing

- Metal machining

- Motor vehicle repair

- Construction

Occupational lung diseases include asbestosis among asbestos miners and those who work with friable asbestos insulation, as well as black lung (coalworker's pneumoconiosis) among coal miners, silicosis among miners and quarrying and tunnel operators and byssinosis among workers in parts of the cotton textile industry.

Occupational asthma has a vast number of occupations at risk.

Bad indoor air quality may predispose for diseases in the lungs as well as in other parts of the body.

Infants may develop respiratory symptoms as a result of exposure to a specific type of fungal mold, called Penicillium. Signs that an infant may have mold-related respiratory problems include (but are not limited to) a persistent cough and/or wheeze. Increased exposure increases the probability of developing respiratory symptoms during their first year of life. Studies have shown that a correlation exists between the probability of developing asthma and increased exposure to "Penicillium". The levels are deemed ‘no mold’ to ‘low level’ , from ‘low’ to ‘intermediate’ , and from ‘intermediate’ to ‘high’.

Mold exposures have a variety of health effects depending on the person. Some people are more sensitive to mold than others. Exposure to mold can cause a number of health issues such as; throat irritation, nasal stuffiness, eye irritation, cough and wheezing, as well as skin irritation in some cases. Exposure to mold may also cause heightened sensitivity depending on the time and nature of exposure. People at higher risk for mold allergies are people with chronic lung illnesses, which will result in more severe reactions when exposed to mold.

There has been sufficient evidence that damp indoor environments are correlated with upper respiratory tract symptoms such as coughing, and wheezing in people with asthma.

The incidence of mesothelioma has been found to be higher in populations living near naturally occurring asbestos. People can be exposed to naturally occurring asbestos in areas where mining or road construction is occurring, or when the asbestos-containing rock is naturally weathered. Another common route of exposure is through asbestos-containing soil, which is used to whitewash, plaster, and roof houses in Greece. In central Cappadocia, Turkey, mesothelioma was causing 50% of all deaths in three small villages—Tuzköy, Karain, and Sarıhıdır. Initially, this was attributed to erionite. Environmental exposure to asbestos has caused mesothelioma in places other than Turkey, including Corsica, Greece, Cyprus, China, and California. In the northern Greek mountain town of Metsovo, this exposure had resulted in mesothelioma incidence around 300 times more than expected in asbestos-free populations, and was associated with very frequent pleural calcification known as "Metsovo Lung".

The documented presence of asbestos fibers in water supplies and food products has fostered concerns about the possible impact of long-term and, as yet, unknown exposure of the general population to these fibers.

Exposure to talc is also a risk factor for mesothelioma; exposure can affect those who live near talc mines, work in talc mines, or work in talc mills.

In the United States, asbestos is considered the major cause of malignant mesothelioma and has been considered "indisputably" associated with the development of mesothelioma. Indeed, the relationship between asbestos and mesothelioma is so strong that many consider mesothelioma a “signal” or “sentinel” tumor. A history of asbestos exposure exists in most cases.

Pericardial mesothelioma may not be associated with asbestos exposure.

Asbestos was known in antiquity, but it was not mined and widely used commercially until the late 19th century. Its use greatly increased during World War II. Since the early 1940s, millions of American workers have been exposed to asbestos dust. Initially, the risks associated with asbestos exposure were not publicly known. However, an increased risk of developing mesothelioma was later found among naval personnel (e.g., Navy, Marine Corps, and Coast Guard), shipyard workers, people who work in asbestos mines and mills, producers of asbestos products, workers in the heating and construction industries, and other tradespeople. Today, the official position of the U.S. Occupational Safety and Health Administration (OSHA) and the U.S. EPA is that protections and "permissible exposure limits" required by U.S. regulations, while adequate to prevent most asbestos-related non-malignant disease, are "not" adequate to prevent or protect against asbestos-related cancers such as mesothelioma. Likewise, the British Government's Health and Safety Executive (HSE) states formally that any threshold for exposure to asbestos must be at a very low level and it is widely agreed that if any such threshold does exist at all, then it cannot currently be quantified. For practical purposes, therefore, HSE assumes that no such "safe" threshold exists. Others have noted as well that there is no evidence of a threshold level below which there is no risk of mesothelioma. There appears to be a linear, dose-response relationship, with increasing dose producing increasing risk of disease. Nevertheless, mesothelioma may be related to brief, low level or indirect exposures to asbestos. The dose necessary for effect appears to be lower for asbestos-induced mesothelioma than for pulmonary asbestosis or lung cancer. Again, there is no known safe level of exposure to asbestos as it relates to increased risk of mesothelioma.

The time from first exposure to onset of the disease, is between 25 and 70 years. It is virtually never less than fifteen years and peaks at 30–40 years. The duration of exposure to asbestos causing mesothelioma can be short. For example, cases of mesothelioma have been documented with only 1–3 months of exposure.

Symptoms of mold exposure can include:

- Nasal and sinus congestion, runny nose

- Respiratory problems, such as wheezing and difficulty breathing, chest tightness

- Cough

- Throat irritation

- Sneezing / Sneezing fits

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.

Working with asbestos is the most common risk factor for mesothelioma. However, mesothelioma has been reported in some individuals without any known exposure to asbestos.

Pneumoconiosis is an occupational lung disease and a restrictive lung disease caused by the inhalation of dust, often in mines and from agriculture.

In 2013, it resulted in 260,000 deaths, up from 251,000 deaths in 1990. Of these deaths, 46,000 were due to silicosis, 24,000 due to asbestosis and 25,000 due to coal workers pneumoconiosis.

A 2017 SBU report found evidence that workplace exposure to silica dust, engine exhaust or welding fumes is associated with heart disease. Associations also exist for exposure to arsenic, benzopyrenes, lead, dynamite, carbon disulphide, carbon monoxide, metalworking fluids and occupational exposure to tobacco smoke. Working with the electrolytic production of aluminium or the production of paper when the sulphate pulping process is used is associated with heart disease. An association was also found between heart disease and exposure to compounds which are no longer permitted in certain work environments, such as phenoxy acids containing TCDD(dioxin) or asbestos.

Workplace exposure to silica dust or asbestos is also associated with pulmonary heart disease. There is evidence that workplace exposure to lead, carbon disulphide, phenoxyacids containing TCDD, as well as working in an environment where aluminium is being electrolytically produced, is associated with stroke.

In 2013 pneumoconiosis resulted in 260,000 deaths up from 251,000 deaths in 1990. Of these deaths 46,000 were due to silicosis, 24,000 due to asbestosis and 25,000 due to coal workers pneumoconiosis.

Unfortunately for non-healthcare professionals, healthcare professionals can use many different words for pulmonary toxicity and still understand each other completely. Yet, for laypersons, this can lead to some difficulties while searching for information about pulmonary toxicity (or about any other side effect). Here are some words that are rather similar to each other in meaning for healthcare professionals. Side effect = adverse event (AE) = adverse drug reaction (ADR) = adverse reaction = toxicity. Pulmonary = lung. Pulmonary toxicity = pulmonary injury = lung injury = lung toxicity. And instead of pulmonary toxicity (a general term), the specific name of the specific side effect in question can be used, e.g. pneumonitis or radiation pneumonitis. Any combination is also possible, of course.

There is no cure available for asbestosis. Oxygen therapy at home is often necessary to relieve the shortness of breath and correct underlying low blood oxygen levels. Supportive treatment of symptoms includes respiratory physiotherapy to remove secretions from the lungs by postural drainage, chest percussion, and vibration. Nebulized medications may be prescribed in order to loosen secretions or treat underlying chronic obstructive pulmonary disease. Immunization against pneumococcal pneumonia and annual influenza vaccination is administered due to increased sensitivity to the diseases. Those with asbestosis are at increased risk for certain cancers. If the person smokes, quitting the habit reduces further damage. Periodic pulmonary function tests, chest x-rays, and clinical evaluations, including cancer screening/evaluations, are given to detect additional hazards.

Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.

People who worked in jobs with high asbestos dust exposure are at the highest risk of developing asbestos-related disease. However, exposure to asbestos may also occur in the worker’s home due to dust that has accumulated on the worker's clothing (para-occupational exposure). Asbestos-related diseases can also occur as a result of non-occupational, environmental exposure. Asbestos was extensively used in many building materials, therefore large quantities of asbestos still remain in buildings that were built prior to the restriction of asbestos use that applies in many countries. The weathering and aging of such buildings may cause asbestos fragments to be released in the air and create a potential hazard. Anyone who disturbs the asbestos-containing material during home maintenance and renovation can be affected, although the exact risks are difficult to quantify.

Asbestosis is long term inflammation and scarring of the lungs due to asbestos. Symptoms may include shortness of breath, cough, wheezing, and chest pain. Complications may include lung cancer, mesothelioma, and pulmonary heart disease.

Asbestosis is caused by breathing in asbestos fibers. Generally it required a relatively large exposure over a long period of time. Such levels of exposure typically only occur in those who work with the material. All types of asbestos fibers are associated with concerns. It is generally recommended that currently existing asbestos be left undisturbed. Diagnosis is based upon a history of exposure together with medical imaging. It is a type of interstitial pulmonary fibrosis.

There is no specific treatment. Recommendations may include stopping smoking, influenza vaccination, pneumococcal vaccination, or oxygen therapy. Asbestosis affected about 157,000 people and resulted in 3,600 deaths in 2015. Asbestos use has been banned in a number of countries in an effort to prevent disease.

Pulmonary toxicity is possible due to many chemical compounds. However, the most famous (infamous) example is pulmonary toxicity due to asbestos. Asbestos can lead to a highly dangerous (i.e., highly malignant) lung cancer called malignant pleural mesothelioma, sometimes also simply called mesothelioma. As a consequence, the use of asbestos is now completely prohibited by law in most countries.

Though heart disease is not exclusive to the poor, there are aspects of a life of poverty that contribute to its development. This category includes coronary heart disease, stroke and heart attack. Heart disease is the leading cause of death worldwide and there are disparities of morbidity between the rich and poor. Studies from around the world link heart disease to poverty. Low neighborhood income and education were associated with higher risk factors. Poor diet, lack of exercise and limited (or no) access to a specialist were all factors related to poverty, though to contribute to heart disease.

Both low income and low education were predictors of coronary heart disease, a subset of cardiovascular disease. Of those admitted to hospital in the United States for heart failure, women and African Americans were more likely to reside in lower income neighborhoods. In the developing world, there is a 10 fold increase in cardiac events in the black and urban populations.
