What harm does pesticide residue belong to and how to deal with pesticide packaging waste?

A: Pesticide residue is a man-made chemical hazard, which refers to the total name of undecomposed trace pesticide precursors, toxic metabolites, degradation products and impurities left in organisms, harvests, soil, water and atmosphere after pesticide application in agricultural production. Agricultural packaging waste is best recycled by qualified processing units.

1. What are the hazards of pesticide residues?

1, pesticide residue belongs to man-made chemical hazards, which refers to the general name of trace pesticide precursors, toxic metabolites, degradation products and impurities left in organisms, crops, soil, water and atmosphere after pesticide application in agricultural production.

2. Causes of pesticide residues

(1) Some pesticides, such as organochlorine pesticides such as DDT, are difficult to degrade in soil or plants in a short time and remain for a long time.

(2) Due to the long-term use of pesticides, weed pests have developed drug resistance, or the use method is wrong and the effect is not obvious, which leads users to increase the dosage without authorization in order to achieve better results, thus causing a vicious circle.

(3) The knowledge of pesticides is not enough, only the effect is pursued, and the characteristics of pesticides are not paid attention to. 70% of pesticides are pesticides, 70% are organophosphorus pesticides, and 70% are highly toxic and highly residual pesticides.

(4) The products of some pesticides decomposed by microorganisms in soil are still toxic.

Second, how to deal with pesticide packaging waste

1. Pesticide residues in pesticide packaging waste. If it is randomly discarded in ridges, ponds and rivers, the residual pesticides will enter the surrounding environment and pollute the water and soil.

2. Generally, after spraying pesticides, pesticide packaging wastes should be burned centrally. Although it will produce harmful gases, it can reduce environmental pollution to a certain extent. If there is a special pesticide packaging waste recycling station in the local area, it is best to send the packaging waste to the recycling station for recycling by professionals.
