Title Relationship between exposure to chlorpyrifos and concentration of urinary alkylphosphates in termite control workers

Abstract A study was made of workers spraying chlorpyrifos (CP) both under floors and around houses. All under-floor sprayers wore respirators. CP levels in air near the breathing zone, amounts of CP in contact with skin, and urinary alkyl phosphate (diethyl phosphate and diethyl thiophosphate) levels were higher in the under-floor sprayers. The total urinary alkyl phosphate level was more closely correlated with the amounts of CP in contact with skin than with the personal ambient CP level. Respiratory absorption of CP was prevented by the use of a respirator, so the urinary alkyl phosphates were mainly derived from the dermal absorption of CP. Biological monitoring using urinary alkyl phosphate levels is a useful index for CP exposure.
