What happens to pesticides once they leave the human body?
The rest will either pass through the body harmlessly or be metabolized. If metabolized, either they become deactivated/detoxified or, if you drank a non-food-safe pesticide straight out of the bottle in an effort to kill yourself, they turn into a toxin. You won’t find those pesticides on food in any dosage that matters.

How does EPA determine what the effects of pesticides on humans are and whether they are acceptable?
A major consideration in approving pesticides for use is whether they pose an unreasonable risk to humans. EPA assesses risks associated with individual pesticide active ingredients, as well as with groups of pesticides that have a common toxic effect. This latter assessment is called cumulative risk assessment and is designed to evaluate the risk associated with exposure at one time to multiple pesticides that act the same way in the body.
What determines what precautions must appear on the pesticide label?
Beyond the basic approval process for pesticides, which requires pesticides to meet a standard for safety to humans and the environment, the degree of toxicity determines what precautions must appear on the pesticide label. These include, for example:

What is the most common insecticide poisoning?
Most serious insecticide poisonings result from the organophosphate and carbamate types of insecticides, particularly when used in suicide attempts and, when accidental, in occupational settings. Organophosphates include malathion, parathion, fenthion, dursban, diazinon, chlorpyrifos, and sarin. Some of these compounds are derived from nerve gases.

Many insecticides can cause poisoning after being swallowed, inhaled, ...
What is the best treatment for organophosphate poisoning?
Atropine , given by vein, can relieve most of the symptoms of organophosphate poisoning. Pralidoxime, given by vein, can speed up recovery of nerve function, eliminating the cause of the symptoms.

Can insecticides cause poisoning?
Many insecticides can cause poisoning after being swallowed, inhaled, or absorbed through the skin. Some insecticides are odorless, thus the person is unaware of being exposed to them. Organophosphate and carbamate insecticides make certain nerves “fire” erratically, causing many organs to become overactive and eventually to stop functioning.

Why are pesticides harmful to workers?
Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses. Exposure can occur through inhalation of pesticide fumes, and often occurs in settings including greenhouse spraying operations and other closed environments like tractor cabs or while operating rotary fan mist sprayers in facilities or locations with poor ventilation systems. Workers in other industries are at risk for exposure as well. For example, commercial availability of pesticides in stores puts retail workers at risk for exposure and illness when they handle pesticide products. The ubiquity of pesticides puts emergency responders such as fire-fighters and police officers at risk, because they are often the first responders to emergency events and may be unaware of the presence of a poisoning hazard. The process of aircraft disinsection, in which pesticides are used on inbound international flights for insect and disease control, can also make flight attendants sick.
How does pesticide affect wildlife?
An obvious side effect of using a chemical meant to kill is that one is likely to kill more than just the desired organism. Contact with a sprayed plant or "weed" can have an effect upon local wildlife, most notably insects. A cause for concern is how pests, the reason for pesticide use, are building up a resistance. Phytophagous insects are able to build up this resistance because they are easily capable of evolutionary diversification and adaptation. The problem this presents is that in order to obtain the same desired effect of the pesticides they have to be made increasingly stronger as time goes on. Repercussions of the use of stronger pesticides on vegetation has a negative result on the surrounding environment, but also would contribute to consumers' long-term low-level exposure.
