Occupational exposure to benzene: Workers maintaining cargo tanks that contain crude oil residues were exposed to benzene, as documented by blood and urine samples and exposure measurements. Tank workers showed a decline in IgA from baseline to pre-next shift, with suppression correlating with benzene concentrations in blood and urine and time spent in the tank. Declines in IgM and CD4 T cells were also noted. [75]
