The plaintiffs asserted that the EPA must find that the existence of an unreasonable risk of injury to health is more probable than not before it may issue a test rule under the Act. In response, the EPA claimed that it may issue a test rule under the TSCA if the agency determines that there is a substantial probability of an unreasonable risk of injury to health. The test rule required toxicological testing to determine the health effects of the chemical, 2-ethylhexanoic acid, and imposed on exporters of this chemical a duty to file certain notices with the EPA. What standard should be applied? Why?4. How sizing down to Nano affect material properties?
- List five (5) information that you should read on a chemical container and briefly describe their significance in relation to safety.Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD 50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD 50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD 50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 12 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000034 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mLWhat is 4a?
