The Biden administration has officially determined the chemical formaldehyde poses an “unreasonable” risk to human health and should be regulated. The Environmental Protection Agency (EPA ...
The term immediately dangerous to life or health (IDLH) is defined by the US National Institute for Occupational Safety and Health (NIOSH) as exposure to airborne contaminants that is "likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment." Examples include smoke or other ...
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
A 2014 WHO worldwide survey on maternal and perinatal health found a statistically significant association between low birth weights (LBW) and increased levels of exposure to PM 2.5. Women in regions with greater than average PM 2.5 levels had statistically significant higher odds of pregnancy resulting in a low-birth weight infant even when ...
The Environmental Protection Agency (EPA) has determined that breathing in formaldehyde, a chemical that’s used in building materials and hair straighteners, can cause cancer. In a toxicological ...
A long-awaited draft assessment from the EPA says that breathing in the chemical formaldehyde causes cancer, while a new lawsuit alleges that 34 states aren’t following air pollution rules. This ...
Environmental factors such as temperature and relative humidity can elevate levels because formaldehyde has a high vapor pressure. Formaldehyde levels from building materials are the highest when a building first opens because materials would have less time to off-gas. Formaldehyde levels decrease over time as the sources suppress.
The total volatile organic compound levels can reach 7,500 micrograms per cubic meter. [5] Concentrations decayed by approximately 90% over a three-week period. Over sixty chemical compounds were identified inside the interiors of the four vehicles in this study. In some instances, the odor results from a manufacturing defect.
