From the accessible data of the studies carried out so far, a basic summary of their creation was created, and characteristic properties that are essential for the evaluation of adverse effects on human health and the environment. From the field of organophosphorus pesticides, it was found that pesticides containing a phosphorothioate part can be easily oxidized by chlorine to the corresponding oxone derivative, while organophosphorus pesticides with a phosphate part are very stable in the presence of chlorine. The resulting oxon forms can be more effective inhibitors of acetylcholinesterase than their parent compounds and at the same time be stable enough (more than 24 h) to reach the consumer, on whom they can, however, have a negative effect. At the same time, disinfection by- products from pesticides can be more toxic than the original compounds. These include chloroxon, diazoxon and...
