Title Assessment of omethoate and fenitrothion absorption in greenhouse workers using personal protective equipment in confined areas
Original title Valutazione dell'assorbimento di ometoato e fenitrothion durante lavorazioni eseguite con l'uso di mezzi personali di protezione in ambienti confinati [in Italian]

Abstract Sprayers and workers engaged in manual operations in a greenhouse were monitored for exposure to omethoate and fenitrothion. Urinary dialkylphosphates (dimethylthiophosphate and dimethylphosphate) were used as the biological indicators of exposure to the two chemicals. Residues of fenitrothion on foliage were measured as well as levels of fenitrothion and omethoate in air samples collected in the breathing zone (personal sampling) and in the workplace near the entrance and the end of the greenhouse (static sampling). Skin exposure was estimated from pads placed on the thorax under overalls and from hand washing liquid at the end of the workshift. Sprayers wore respiratory and skin protection during the workshift. Workers engaged in manual operations did not wear respiratory protection. Re-entry to the greenhouse was permitted 48h after spraying. Levels of omethoate and fenitrothion in air samples, on pads and on the hands, during manual operation on ornamental plants, were very low. Urine analysis showed no significant difference between levels of urinary dialkylphosphates in the control group and exposed workers. Cholinesterase activity (acetyl and butyryl) showed no significant reduction at the end of the workshift compared with baseline values.
