What Are the Dangers of Chemical Pesticides in Agriculture?

What are the dangers of chemical pesticides in agriculture? Agricultural products are often sprayed with pesticides. Pesticides bear potential dangers for living organisms and the environment. It is important to know them.

Scientific considerations

Chemical pesticides in agriculture The suffix “–cide” means “killing”. Pesticides kill insects, fungi, bacteria, vectors of diseases, and other organisms considered harmful. Pesticides are classified as biological and chemical. Biological pesticides use fungi, bacteria and other organic substances. Biological pesticides are not toxic for humans and animals. Chemical pesticides bear the greatest danger for the environment and health. Broad-spectrum pesticides kill many types of pests. Narrow-spectrum pesticides kill particular types of pests. Pesticides may kill pests on contact or systemically, penetrating inside the pests by means of absorption paths.

What are the dangers of chemical pesticides for environment?

Pesticides are sprayed on particular areas; however they can pave the way into rivers, ponds, seas, and oceans. Water contaminated with pesticides becomes toxic for fish and other living organisms. Pesticides may percolate into groundwater making it unsanitary and unsafe for drinking. Pesticides may turn into gas or vapor after spraying and travel with the air to different areas harming wildlife. Pesticide drifts provoke imbalance of the whole ecosystems.

What are health risks of chemical pesticides in agriculture?

Farmers and other persons working with pesticides are at significant risks. Pesticides are carried with the wind, penetrate into water, leave residues on foods, and remain inside the animal and human bodies. Pesticides enter the body through skin, eyes, nose, and mouth. Pesticides are particularly toxic to humans and animals, and often small amounts of toxins can kill. Pesticide toxins can accumulate in the liver. Toxins may act slowly and cause delayed harm to the body. The victims experience fatigue, skin irritations, nausea, vomiting, suffocation, liver and kidney problems, nervous and blood disorders, and reproductive damage.

Pesticides may accumulate in the colon and then produce slow toxic effects on the body. Pesticides are associated with birth defects, Alzheimer’s disease, attention deficit hyperactivity disorder, and cancers. Pesticides are harmful to nervous, reproductive, and the endocrine systems. Pesticides can pass from the mother to fetus during pregnancy. Women consuming meat that contains pesticides, antibiotics, and growth hormones may pass these compounds to fetus during pregnancy or to infant while feeding it with breast milk. Children consuming foods treated with pesticides and hormones accumulate them in their bodies.

What are protective measures against chemical pesticides in agriculture?

Farmers may be exposed to injurious chemicals. It is important to take all necessary measures to diminish the risks of intoxications. Employees must know how to work with pesticides safely and should be supplied with protective equipment. Workers must also know the warning signs of pesticide poisoning.
