تقويم التلوث الواقع على عمال الرش أثناء تطبيق المبيدات

الملخص EN

The present work aimed at evaluating the contamination of sprayer operators during the actual spraying process in Saudi Arabia under different circumstances (Green houses and open field spraying).

Data indicated that the power sprayer is the most commonly used equipment in green houses or open fields, where the knapsack and compressed air sprayers are used at a very limited scale.

Two application methods are commonly used in open fields and green houses: circle spraying and the up and down spraying of the plants.

It has been found that four primary factors affecting the rate by which the sprayer operators are contaminated are sprayer type, spraying period, application method and spraying conditions.

The power sprayers used in green houses with longer spray period represented highest rates of contamination.
