Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Exposure to diesel exhaust and diesel particulate matter (DPM) is an occupational hazard to truckers, railroad workers, occupants of residential homes in the vicinity of a rail yard, and miners using diesel-powered equipment in underground mines. Adverse health effects have also been observed in the general population at ambient atmospheric ...
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
Ultimately, there is an increasing need due to the presence of climate change and the effects of air pollution on it for more long-term studies, due to these short monitoring sessions being unreliable and lacking the availability to accurately capture data and represent cookstoves' effectiveness and usefulness.

Health effects are concentrated among women, who are likely to be responsible for cooking, and young children. [110] The World Health Organization (WHO) estimates that cooking-related pollution causes 3.8 million annual deaths. [111] The Global Burden of Disease study estimated the number of deaths in 2021 at 3.1 million. [112]
Soot, particularly diesel exhaust pollution, accounts for over one-quarter of the total hazardous pollution in the air. [ 12 ] [ 22 ] Among these diesel emission components, particulate matter has been a serious concern for human health due to its direct and broad impact on the respiratory organs.
That can be dangerous. And as much of the country braces for winter weather, icicles may be a common sight. Icicles clinging to the side of a property can signal trouble in a wide variety of ways.
Flammable applies to combustible materials that ignite easily and thus are more dangerous and more highly regulated. Less easily ignited less-vigorously burning materials are combustible . For example, in the United States flammable liquids , by definition, have a flash point below 100 °F (38 °C)—where combustible liquids have a flash point ...
