Material below on SECOND EXAM: We're exposed to chemicals on daily basis chemicals have made our lives better  some chemicals are intended for human use (i.e. pharmaceuticals) and  exposure, while others are not  all chemicals are potentially toxic      – the  dose makes the poison there are variations in the response  (i.e. susceptibility) of humans to chemicals  which are determined in large part by: genetics age of exposure Chemicals: Toxicants vs. Toxins toxicants : toxic substances that are  man-made  or result from human  (anthropogenic) activity i.e. benzene toxins : usually refers to a toxic substance made by living organisms , including  reptiles, insects, plants, and microorganisms i.e. bitten by a reptile Chemicals in our environment with industrialization, biologic factors often controlled first, i.e. by sanitation industrial/agricultural development create massive dependence on man-made  agents – chemical and physical  ~5 million synthetic agents 60-70 thousand in commercial use

~1,000 new chemicals added annually  in U.S., 0.15B kg to 175B kg 1935-1995 concern from chemicals in the environment originally arose from      occupational       exposures increased production of synthetic organic chemicals – dyes, plastics, solvents,  etc.
