Chlorobenzilate (CB) or ethyl 2-hydroxy-2, 2-di-(p-chlorophenyl)-acetate is formulated as an emulsifiable concentrate and wettable powder and is an acaricide sold under the following trade names: Kop-Mite. Folbex, Benzilan, Acaraben, and Akar. Brady et al. published a method whereby urinary levels of CB analyzed as p, p'-dichlorobenzophenone (DBP) could be determined. A study, on a small number of workers, by Levy et al. suggested that the method was suitable for monitoring citrus field workers for CB exposure. The objective of the current study was to apply the method developed by Brady et al. (1980) to the monitoring of a large number of CB exposed citrus fieldworkers employed in Florida and Texas, in an effort to assess exposure levels experienced during actual work activities. The data in the current study would appear to support the effectiveness of the method by Brady et al. as a monitoring tool for estimating chlorobenzilate exposure, and tends to demonstrate the temporal and occupational gradients that would be expected among exposed workers.
