We developed a mathematical model to compare 2 indoor remediation strategies in the aftermath of an outdoor release of 1.5 kg of anthrax spores in lower Manhattan. The 2 strategies are the fumigation approach used after the 2001 postal anthrax attack and a HEPA/vaccine plan, which relies on HEPA vacuuming, HEPA air cleaners, and vaccination of reoccupants. The HEPA/vaccine approach leads to few...

BACKGROUND Urinary biological monitoring for benzene (by measuring benzene metabolites) in coke oven by-product workers produced the unexpected result that 2 out of 10 employees had significantly raised urinary S-phenylmercapturic acid (S-PMA). However, simultaneous personal air sampling showed no excessive airborne exposure. METHODS Possible causes for this finding were investigated having e...

Three population groups (two of them consisting of school-going children) with a low content of fluoride in the drinking water have been used to investigate parameters influencing fluoride excretion. For the population living in an area contaminated by F-air pollution, there was no significant effect of age or sex from 3 to 17 years. For the population living in a non-contaminated area, there i...
