Exposure to secondhand tobacco smoke (SHS) was one of the leading risk factors for deaths globally in 2019, accounting for approximately 1.3 million deaths and contributing to 37 million Disability-Adjusted life years (DALYs), with 11.2% of the burden in children under the age of 5 years. (tobaccoatlas.org)
It is also referred to as passive smoking, environmental tobacco smoke, and tobacco smoke pollution. (tobaccoatlas.org)

2 Crystalline silica has also been determined to be an occupational lung carcinogen 4,5 and there is evidence that inhaling respirable silica dust causes chronic obstructive pulmonary disease (COPD), chronic renal (kidney) disease and various autoimmune diseases. (cdc.gov)

2007). This study found that AM accounted for only 2-12% of the detected metabolites, that most of the subjects had detectable atrazine exposure, and that future biomonitoring studies would likely need to include analysis of at least AM, DACT, DIA, and DEA in order to characterize the extent of atrazine exposure in a population. (who.int)

Introduction Little is known about joint effects between occupational carcinogens on lung cancer risk. (researchgate.net)

The review included exposure to environmental agents carcinogenic to humans (International Agency for Research on Cancer classification), as well as lifestyle factors known to affect cancer risk. (who.int)
Those include the carcinogenic potency of the substance, the level and duration of exposure, and an individual's susceptibility to the carcinogenic action of the substance. (nih.gov)
Many chemicals on the market and in the environment have not undergone exhaustive carcinogenicity testing, and significant knowledge gaps remain on the potential carcinogenic effects of low levels of exposure to combinations of chemicals throughout our lifetime. (europa.eu)
Exposure to carcinogenic chemicals comes from multiple sources and pathways, including outdoor and indoor air pollution, smoking, either directly or second hand, consumer products, drinking water and food, and in relation to several occupations. (europa.eu)
Apart from carcinogenic chemicals, UV radiation and asbestos, occupational exposure to metals, dusts, ionising radiation, stress and other factors related to work organisation and working conditions have also been linked to cancer. (europa.eu)
Rationale: Benzene has been classified as carcinogenic to humans, but there is limited evidence linking benzene exposure to lung cancer. (researchgate.net)
It was later decided to include nitions of carcinogens were based on pollution, occupational exposure to a review of lifestyle factors that are the January 2013 list of agents classified carcinogenic compounds, and lifestyle known to influence cancer risk. (who.int)

Exposure to secondhand smoke can lead to lung cancer, acute and chronic coronary heart disease (CHD), and eye and nasal irritation in adults. (tobaccoatlas.org)
However, rapidly fatal cases of acute silicosis resulting from very intense exposures over only a few months or years are well documented among sandblasters, tunnelers, miners, and some other occupational groups. (cdc.gov)
The study also found that the proportion of these urinary metabolites varied considerably depending on whether the subjects had high or low acute exposures or whether the subjects had general environmental exposures (i.e., not agricultural workers). (who.int)

State and federal agencies limit exposure to the substance in the workplace and the environment through regulation. (nih.gov)
The most common workplace carcinogens are generated when carrying out specific tasks or applying specific technologies (cutting stone, grinding or cutting wood, welding, processing metal products, combustion, etc.) rather than substances that are marketed or used as such. (europa.eu)
For these process-generated workplace carcinogens, exposure is mainly reduced through prevention measures such as local exhaust ventilation. (europa.eu)

2015). For example, from the priority list of 16 groups of commonly used hazardous substances in the European Human Biomonitoring Initiative (HBM4EU) (HBM4EU, 2022), in which the EEA participated), six groups of substances (anilines, arsenic, cadmium, chromium, mycotoxins and PAHs) include known or presumed carcinogens as set out in the EU Classification, Labelling and Packaging (CLP) Regulation and by the International Agency for Research on Cancer (IARC). (europa.eu)
More than 70 of these compounds are carcinogens, which has led the US Environmental Protection Agency and the International Agency for Research on Cancer to classify SHS as a group A and group 1 carcinogen, respectively, indicating the most hazardous cancer-causing compounds. (tobaccoatlas.org)

Eight substances have been added to the Report on Carcinogens, bringing the total list to 256 substances that are known, or reasonably anticipated, to cause cancer in humans. (nih.gov)
The Working Group concluded that the animal mammary tumors associated with exposure to atrazine involve a non-DNA-reactive, hormonally mediated mechanism that is not relevant to humans. (who.int)
A recent study evaluated the urinary levels of 9 atrazine metabolites in humans and concluded that DACT was the primary metabolite regardless of exposure scenario, and that exposure assessment based on measuring only AM or any single atrazine metabolite resulted in an underestimate of atrazine exposure (Barr et al.

Highest exposure occurs among workers who produce the substance or use it to make flame retardants. (nih.gov)
Initial hazard assessments identified exposure to crystalline silica during hydraulic fracturing as the most significant known health hazard to workers and this has been the focus of the NIOSH study to date. (cdc.gov)
The significance of these findings is that even if workers are properly using half-mask air-purifying respirators, they would not be sufficiently protected because half-mask air-purifying respirators have a maximum use concentration of 10 times the occupational health exposure limit. (cdc.gov)

NIOSH recently collected 116 air samples at 11 different hydraulic fracturing sites in five different states (AR, CO, ND, PA and TX) to evaluate worker exposure to crystalline silica. (cdc.gov)
