Title Studies of the occupational exposure of Malaysian plantation workers to paraquat
Bibliographic information Feb. 1982, Vol.39, No.1, p.23-33. 12 ref.
Abstract Report on quantitative estimates of skin and respiratory exposure of knapsack spray operators, carriers and rubber tappers to paraquat under normal working conditions. Spray operators had skin exposure to paraquat by walking through recently sprayed vegetation and into their own spray, during the adjustment and unblocking of spray nozzles, and as the result of leakage and overfilling of spray tanks. Carriers also had skin exposure due to contact with recently sprayed vegetation and accidental spillage. Tappers had only infrequent and negligible skin exposure. Determinations of total airborne paraquat concentrations in the breathing zone showed that spray operators and carriers are exposed to an order of 1% or less of the current TLV for respirable paraquat (100µg/m3). No paraquat was detected in the breathing zone of tappers. Under the conditions studied, there should be no toxicological risk to any of the 3 groups studied.
