Humans are primarily exposed to this compound occupationally, by inhalation near source areas, and by ingestion of contaminated drinking water. The products observed from the reaction of hydroxide radicals with the 1,3-dichloropropene isomers were formyl chloride and chloroacetaldehyde, with unit yields. The fumigant will bind to the soil, degrade, leach, or be vented into the atmosphere. In soils simulating the structure and moisture conditions that may occur in the field during fumigation, was adsorbed . An increase in temperature, increases the Henry's Law constant and diffusion of 1,3-dichloropropene through soil and shortens the volatilization time .
Adsorption is higher in dry soils than in moist soil .
However, water-saturated soils have air passageways blocked and fumigant movement is decreased . The concentration of a mixture of 1,3-dichloropropene was monitored at ground level and at 42 inches above ground after fumigant was applied to a pineapple field at a depth of 18 inches . The reduced adsorption due to increased soil moisture, resulted in a transfer of fumigant from soil to water at or near the soil surface, after which evaporation occurred. At 42 inches above ground level, 1,3-dichloropropene was still detectable and was probably drifting in from other fields . 1,3-Dichloropropene was injected 0.2 m deep into the soil of three flower bulb fields during summer.
