It's said that farm chemicals are widely used in the growth vegetables and fruits. They can do harmto health, resulted in nerve disorders, hormone imbalance, intelligence problems and so on.

They can be classified into different types. Some are used to kill pests, called pesticide and some are designed to destroy plants or inhibits their growth, called herbicide. For instance, Alachlor (15972-60-8) is mainly used to clear away the weeds before seedling, as it can inhibit bud protein taking in shape. However, it cause slight skin and eye irritation. It may pose danger to internal organs, such as liver, kidney and spleens, etc.

Though some fruits and vegetables are left with pesticides or herbicide, their benefits to people outweigh their defects. As long as we keep good diet habits, the hazards can be reduced greatly. You'd better cook vegetables and peel fruits before dining.

I think there seems no better way to avoid it unless we do not take them as food.
