How pesticides enter our body

Many pesticide formulations had introduced due to the rapid growth in the global pesticide market result from the wide use of pesticides in agricultural and non-agricultural sectors. The occurrence of pesticides in the water body is derived by the runoff from the agricultural field and industrial wastewater.

Soluble pesticides were carried away by water molecules especially during the precipitation event by percolating downward into the soil layers and eventually reach surface waters and groundwater. Consequently, it degrades water quality and reduces the supply of clean water for potable water.

Long-time exposure to the low concentration of pesticides had resulted in non -carcinogenic health risks. The conventional method of pesticide treatment processes en compasses coagulation-flocculation, adsorption, filtration and sedimentation, which rely on the phase transfer of pollutants.

We also drink pesticides in drinking water. This is stated by the study: Pesticides in Drinking Water-A Review, published on the International journal of environmental research and public health.

The researchers explained: "The ubiquitous problem of pesticide in aquatic environment are receiving worldwide concern as pesticide tends to accumulate in the body of the aquatic organism and sediment soil, posing health risks to the human.

Those methods are often incurred with a relatively high operational cost and may cause secondary pollution such as sludge formation. Advanced oxidation processes (AOPs) are recognized as clean technologies for the treatment of water containing recalcitrant and bio-refractory pollutants such as pesticides.

It has been adopted as recent water purification technology because of the thermodynamic viability and broad spectrum of applicability. This work provides a comprehensive review for occurrence of pesticide in the drinking water and its possible treatment." Worldwide, the UN, more specifically the FAO, defines as a pesticide any substance, single or mixed with others, intended to destroy or control any harmful organism, prevent or prevent its damage, including vectors of human and animal diseases unwanted species of plants or animals that cause damage or otherwise interfere during the production, processing, storage, transport and marketing of food, foodstuffs, wood and its derivatives, zootechnical feed, as well as substances that may be intended for animals to control insects, mites or other harmful organisms administered or applied to them.

Substances intended for use as plant growth regulators, defoliants, desiccants, thinners or fruit anti-drops are included. Also those applied to crops before or after harvest to protect it from deterioration during storage and transport.
