Characteristics of persistent organic pollutants

First, accumulation. In other words, it can stay in the environment for a long time. Generally speaking, its chemical composition contains chlorine. Adding chlorine atoms to the structure of organic carbon compounds will greatly increase the stability of this compound. Of course, it will be a threat to the whole ecosystem and human health for a long time.

Second, scalability. Its characteristic is that it can be amplified step by step through the food chain, that is to say, in the natural environment, there may be extremely low concentrations in the atmosphere, water and soil, and even this concentration cannot be monitored, but it can enter plants or lower organisms through the atmosphere, water and soil, and then gradually amplify the trophic level. The higher the trophic level, the higher the accumulation, the highest for human beings, and finally the great influence on human beings.

Thirdly, for Pops, it is semi-volatile, that is, it has a certain volatility, which determines that it can drift around the world and can drift to some areas in a long distance, that is, areas where Pops are not produced or used at all, but it can be moved to that place because of its long-distance drift.

Fourth, it has a very serious impact on health and ecology. At present, the evidence of epidemiological research is not sufficient, but there are many signs that it has a serious impact on ecology and human health. Its main feature is its hormonal activity, mainly the effect of estrogen.
