Aspects regarding the influence of pesticides on the trophic system: soil-water-plant

Résumé

The issue of residual pesticides in food is of great importance worldwide today. This situation has led many countries to draw up rules with limited quantities allowed in food. Their very high toxicity causes acute intoxications, accumulation in the body and chronic poisoning. Pesticides are highly dangerous compounds due to the persistence in the environment, accumulation of residues in food, infiltration into soil, transmission into wastewater, rivers and lakes, migration into deep soil layers, interstitial and groundwater, and atmospheric formation by air currents. Uncontrolled accumulation and migration into soil and groundwater of pesticides can lead to significant distortions in environmental factor parameters. The purpose of the work was to quantify the results by applying a neonicotinoid pesticide treatment on onion cultivation throughout the life cycle. The work demonstrates the need, but also the toxicity of pest control substances.
