Editor-De Cock et al` note that waiting times to conception are significantly longer in the wives of men exposed to pesticides. They cite the evidence that the nematocide dibromochloropropane (DBCP) is associated with diminished sperm counts.2 It is worth noting that there is other evidence of hazard in these men. They reportedly have significantly high gonadotrophin concentrations although the...

Introduction Whiteboards have, for the most part, replaced the traditional chalk board in the classroom setting. Potential for exposures to individual users has been investigated. For one user, even with heavy use, the maximum solvent exposure measured is <2 ppm of solvent. CPSC has recently been contacted by school systems that describe a new use of these markers. Whiteboards are cut up into s...

You base your MRLs for copper of 0.02 mg/kg/d for acute and intermediate exposures on a study by Pizarro et al. (1999a) who found that gastrointestinal symptoms occurred when adults were exposed to a concentration of copper ≥ 3 mg/L but that there were no increases in symptom incidence at 1 mg/L. This study, however, as were other studies by this group, was designed to address issues of safe wa...

The interest was justified by the wide exposure in the workplace and in the general environment and by the evidence of their specific biological and toxicological effects. During the last 2 decades of 20th century the availability of indicators of exposure or of internal dose has substanti...
