Paraquat-Exposition in der Landwirtschaft
Determinants of dermal exposure (01.01.05)
Blanco LE, Aragón A, Lundberg I, Lidén C, Wesseling C, and Nise G, Determinants of dermal exposure among Nicaraguan subsistence farmers during pesticide applications with backpack sprayers, Annals of Occupational Hygiene 49(1), 17-24, 2005
A study on factors influencing skin exposure of workers (based on videotaped observation and tracing with fluorescent dye) found that the following factors were associated with an increased visual score of exposure: temperature, using a hand-pressurised sprayer, volume of sprayed diluted solution, spraying with the nozzle directed in front, splashing on the feet and gross contamination of hands. In statistical analysis factors related to working practices explained 52% of variability of the total visual score (exposure). Factors related to equipment and working environment explained 33% and 25% of the score, respectively. Several factors were strongly associated with an increased score (exposure): sprayed area, spraying on wet/muddy terrain, use of a manual backpack sprayer and direct contact with spray solution. The main factor with a preventive effect was wearing long pants. A suitable education programme for the farmers in this study should emphasise maintenance of the equipment, the correct spraying technique when using manual backpacks and the type of clothes to wear during applications, in particular the use of gloves.
