Abstract:
Farmers usually inhale toxic chemicals when they are spraying their fields with pesticides.
To obtain basic data for estimating the extent to which their respiratory organs are exposed to risks, the size of droplets of the liquid-type pesticides was measured and the distribution of these particles by size was studied.
For this purpose, an MgO measuring plate (coated with MgO particles) as an agent to capture droplets of the pesticides was devised, and the impinger-man-respirator system was employed. The results were satisfactory.
The droplet-size distributions showed that the sizes of particles range from 1μ to 66μ. About 90% of the particles were less than 20p in size, and particles of 5μ to 15μ made up 70% of the whole.
