Agent Orange, a defoliant used by the British in the Malayan Emergency and the U.S. in the Vietnam War, was equal parts 2,4,5-T and 2,4-D (2,4-dichlorophenoxyacetic acid). 2,4,5-T itself is toxic with a NOAEL of 3 mg/kg/day and a LOAEL of 10 mg/kg/day. [3] Agent Pink contained 100% 2,4,5-T (dioxin
A study published Friday suggests that around 50,000 current cases of pediatric asthma in the U.S. are linked to long-term exposure to nitrogen dioxide from gas and propane stoves.
Occupational exposure to benzalkonium chloride has been linked to the development of asthma. [36] In 2011, a large clinical trial designed to evaluate the efficacy of hand sanitizers based on different active ingredients in preventing virus transmission amongst schoolchildren was re-designed to exclude sanitizers based on benzalkonium chloride ...
