Document Summary
Discuss green chemistry research applications and educational activities. Replace toxic chemical with chemical of equal or greater toxicity. Historically occurred when chemical banned (government, industry etc. ) with little to no review of toxicity of replacement. Niosh studies document association of cumulative exposure to diacetyl vapor over time and abnormal lung function among microwave popcorn workers(https://www. cdc. gov/niosh/docs/2016-111/default. html) Close structural analog substitutes: 2, 3 pentanedione, 2,3-hexanedione and 2,3- heptanedione- similar toxicity to diacetyl. Toxicity data gaps especially on mixed exposures. Relying on engineering controls and ppe to prevent illnesses. Evaluates whether products on the market impact human health and the environment. Why we need a science of safer chemistry. Ability to foresee and avoid adverse health effects from chemical exposures is limited. Science is not keeping pace with new agents entering the market. Exposures are difficult to track and can be significant at low levels.
