Title Unexpected cause of raised benzene absorption in coke oven by-product workers
Bibliographic information June 2006, Vol.56, No.4, p.269-271. 4 ref.
Abstract Urinary biological monitoring for benzene (by measuring benzene metabolites) in coke oven by-product workers produced the unexpected result that two out of ten employees had significantly raised urinary S-phenylmercapturic acid. However, simultaneous personal air sampling showed no excessive airborne exposure. Possible causes for this finding were investigated having excluded inhalation as the route of uptake. It was suspected that skin absorption via contaminated overalls was the possible mechanism and a standard frequency for overall change was introduced. It was found that changing overalls after every four shifts reduced uptake levels to less than the equivalent of the 1ppm inhaled dose for all employees. It is concluded that skin absorption of benzene from contaminated overalls in coke oven by-product workers can be significant and therefore overalls should be changed on a regular and frequent basis.
