PlasticsMaterials with large molecular chains of natural or fossil raw materials, produced by chemical or biochemical reactions. More are everywhere – no surprise plasticsMaterials with large molecular chains of natural or fossil raw materials, produced by chemical or biochemical reactions. More are used even in agriculture – the fields are full of it – mulch foils, foil tunnels, irrigation systems. The end of life of these products is usually not taken into account. Many of these are never collected and growing amounts of plasticsMaterials with large molecular chains of natural or fossil raw materials, produced by chemical or biochemical reactions. More and microplasticsMicroplastics is a general term for plastic fragments of various origins up to 5mm in size. Their existence is mainly associated with their presence i… More in soil contribute to soil degradation and poor water retention.

Plastics are mixtures of polymers and additives adjusting the material properties. It was shown that additives like triclosanTriclosan is chemically called 5-Chloro-2-(2,4-dichlorophenoxy)phenol, it is a compound with strong antimicrobial and antifungal effects. It is added … More and bisphenol A in microplastics impair viability and activity of organisms. 8, 9
