 Abstract
Diffusion and accumulation of ethoprophos in fruit such as apple and two types of pears were examined by dipping them into the solution of ethoprophos. The effective diffusivities of ethoprophos at the skin and flesh of apple and pear were determined by simulation their experimental accumulation curves with calculated ones from the model assuming consecutive diffusion of ethoprophos from skin to flesh. Its effective diffusivity at the flesh with higher content of water were higher, , regardless of the types of fruits, while that at the skin was small, and increased with the order of `Niitaka` pear < `Whangkeumbae` pear < `Fuji` apple. The variation in the concentration of ethoprophos in its solution did not induce any change in affecting its effective diffusivity at the flesh of `Whangkeumbae` pear, but the increase in the concentration caused the increase in its effective diffusivity at the skin. The penetration rate of ethoprophos at the skin was an important factor in determining its accumulation rate in fruit.
