Less well known, but following the same pattern, are efforts being mounted to question studies documenting the adverse health effects of exposure to lead, mercury, vinyl chloride, chromium, beryllium, benzene, and a long list of pesticides and other toxic chemicals. Polluters and manufacturers of dangerous products hire experts in what they call product defense to dissect every study whose findings they oppose, highlighting flaws and inconsistencies.
