Testing for chemical health and safety understanding

For monitoring the test, environmental, and experimental systems, both Dr. Fishbein and Dr. McKinney described some of the powerful tools which can be applied to explore, interpret, and understand situations affecting our health and safety. These tools are applied to nitrosamines and dioxins, which are families of toxic chemicals isolated, purified, and characterized by chemical and physical techniques operating at levels of parts per billion and below. (Remember that 1 part per billion is one second in 33 years 1 teaspoonful of vermouth in a U0,000 gallon tank of gin.)...
