The compound 2-chlorobenzalmalononitrile (also called o-chlorobenzylidene malononitrile; chemical formula: C 10 H 5 ClN 2), a cyanocarbon, is the defining component of the lachrymatory agent commonly referred to as CS gas, a tear gas which is used as a riot control agent, and is banned for use in warfare due to the 1925 Geneva Protocol.
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 ...
However, this increase in private cost is offset by savings in health costs for the public, as there is a lesser amount of disease-causing particulate matter and pollution in the air. Exposure to air pollution can lead to respiratory and cardiovascular diseases, which is estimated to be the cause for 6,20,000 early deaths in 2010, and the ...
Large exposures can result in loss of consciousness, arrhythmias, seizures, or death. [1] [2] The classically described "cherry red skin" rarely occurs. [2] Long-term complications may include chronic fatigue, trouble with memory, and movement problems. [5] CO is a colorless and odorless gas which is initially non-irritating. [5]
However, if one measuring 50-meters-wide and speeding towards Earth at roughly 9 miles per second exploded in the air, it would be rather catastrophic. The probable effect has been likened to just ...
Sudanese forces extensively used CS gas during the latest wave of demonstrations began in 2018. [40] The use of CS gas fired through rifles or hand grenades is not exclusive to police forces but is widely used by non-trained militia to suppress protesters movement and to intimidate civilians by firing blindly into neighborhoods and homes.

[2] [3] As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit [4] and 13 of the world's 20 cities with the highest annual levels of air pollution are in India. [5] The main contributors to India's particulate air pollution include industrial and vehicular emissions ...
