Report on carcinogens

Aristolochic acids are known to be human carcinogens based on sufficient evidence of carcinogenicity from studies in humans and supporting data on mechanisms of carcinogenesis. Evidence of carcinogenicity from studies in experimental animals supports the findings in humans..

Nitromethane is a nitroalkane compound that is a colorless oily liquid with a fruity odor at room temperature. It is soluble in water, alcohol, ether, acetone, and dimethylformamide. Nitromethane is sensitive to shock and is unstable when heated. It also forms an explosive sodium salt that bursts into flame on contact with water ( Akron 2009 ).Studies on Mechanisms of Carcinogenesis. Chloramphenicol inhibits protein synthesis in the mitochondria of mammalian cells (by binding to ribosomes), which accounts for the sensitivity of proliferating tissues, such as those that promote the formation of blood cells, to its toxicity. Anemia, including aplastic anemia, is a recognized hazard ...NTP Report on Carcinogens 1997 Background Document for Saccharin Proposed Report on Carcinogens Delisting for Saccharin. 1 .
