The article discusses the Agency for Toxic Substances and Disease Registry's (ATSDR) task to protect communities from the harmful effects of environmental contaminants. Topics covered include ATSDR's reliance on environmental data by other agencies, factors that are considered before conducting exposure investigation (EI) at a site, and the EI methodology and process. Also noted is ATSDR's evaluation of blood lead and urine arsenic levels in a Montana community with past smelting activities.

Background: Occupational exposure to chemotherapeutic agents in hospitals is a critical issue. Here, we focused on occupational exposure to platinum-based anti-cancer drugs (PDs) by evaluating platinum concentrations in hair and environmental workplace samples to monitor the risk among workers. Methods: Hospital workers who dealt with or without PDs, patients treated with PDs, and non-medical office workers outside the hospital donated hair samples and completed a questionnaire regarding their history of handling PDs, including any incidents. Hair samples were collected and surface wipe sampling was performed in July 2010 and April 2015, before and after moving to a new building and introducing a revised safety program in August 2010. Samples were analyzed by inductively coupled plasma-mass spectrometry. Results: Platinum concentrations in hair from PDs-handling workers was significantly higher than in non-PDs-handling workers (P = 0.045), although 50 times lower than that from PDs-treated patients. Platinum concentrations in the hospital environment had decreased at the second survey 5 years later but had not changed significantly in the hair samples from hospital workers. Conclusion: Platinum concentrations in hair are likely dependent on the frequency of handling PDs. Reduced environmental contamination from PDs did not influence platinum levels in hospital workers' hair. Continuous monitoring by measuring platinum concentrations in the environment and in hair would provide information regarding these issues. [ABSTRACT FROM AUTHOR]
