Document Summary
Estimate of the number of chemicals in use in the usa. 50 000 additional chemicals in common use epa. 2005-2015: 2800 phases in cmp 1 and 2. 2016-2020: 1500 remain in cmp 3 (only 4 years) Phase i has the most data in the largest amount. The banning of some of bisphenol a and flame retardants are part of phase i. In phase ii, we don"t have a final government ruling on all the plasticides although we should get one this year. Exposure = how much x how often x how long working in a bbq kitchen - high exposure. Determining action in response to exposure e. g. barbecuing once a year - low exposure to chemicals and toxins vs. Can rank exposure based on its rating of oel (occupational exposure limit) Low exposure can have high toxicity but it still may be safe products as well. You can also have high exposure to low toxicity.
