Do Pesticides affect human health?

Pesticides can affect humans. How a pesticide affects human health depends on:

        type of pesticide

        and the variable toxicity

        Plus the rate and intensity of reaction when it comes into contact with the body.

However, in many cases, the amount of pesticide that people are likely to be exposed is too small.

How do Pesticides enter the human body?

Pesticides can enter the human body by common accidents. This is done either through

        Inhalation

How do pesticides harm human health?

        Some pesticides affect the body at the point of contact. These are called "local" effects

        Some pesticides can "sensitize" the body when they come into contact with it.

        Some pesticides affect the body after they are absorbed.

        Some pesticides can cause illness immediately or soon after exposure. These are called "acute" effects

        Some pesticides cause illness months or even years after exposure. These are called "chronic" effects.

        Cancer

        Birth defects

        Genetic mutations
