Despite common belief that SO 2 was the main source of the asthma, by investigating sulfur dioxide and sulfur trioxide levels in Yokkaichi and analyzing compound toxicity levels, a study conducted in 1984 from Yokohama National University concluded that respiratory diseases were not a result of sulfur dioxide, but rather due to a titanium oxide ...
Air pollution can negatively affect a pregnancy resulting in higher rates of preterm births, growth restriction, and heart and lung problems in the infant. [22] Compounds such as carbon monoxide, sulfur dioxide and nitrogen dioxide all have the potential to cause serious damage when inhaled by an expecting mother. [23]
The following is a list of chemicals published as a requirement of Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as California Proposition 65, that are "known to the state to cause cancer or reproductive toxicity" as of January 3, 2020. [1]

Sulfur trioxide is a reagent in sulfonation reactions. Dimethyl sulfate is produced commercially by the reaction of dimethyl ether with sulfur trioxide: [20] CH 3 OCH 3 + SO 3 → (CH 3) 2 SO 4. Sulfate esters are used as detergents, dyes, and pharmaceuticals. Sulfur trioxide is generated in situ from sulfuric acid or is used as a solution in ...
The composition of particulate matter that generally causes visual effects, haze, consists of sulfur dioxide, nitrogen oxides, carbon monoxide, mineral dust, and organic matter. The particles are hygroscopic due to the presence of sulfur, and SO 2 is converted to sulfate when high humidity and low temperatures are present.
Sulfur mustard is a vesicant alkylating agent with strong cytotoxic, mutagenic, and carcinogenic properties. After exposure, victims show skin irritations and blisters. [18] [19] This agent also causes respiratory tract lesions, bone marrow depression, and eye damage, the epithelial tissues of these organs being predominately affected ...
Respiratory capacity is further reduced due to selenium binding to hemoglobin. Other problems include degeneration of liver tissue, swelling around the heart, damaged egg follicles in ovaries, cataracts, and accumulation of fluid in the body cavity and head. Selenium often causes a malformed fish fetus which may have problems feeding or ...
