  • chemical pollution includes all the major pollutants resulting from human activity such as drugs, pesticides, hydrocarbons, metals and heavy metals... These chemicals are dangerous for the environment which they pollute durably because of their high toxicity and low biodegradability. Current sanitation systems (collective or not) are very inefficient in the face of this complex and varied pollution. Pollutants therefore end up in the natural environment and are bio-accumulated. In this way, they move up the food chain and increase their concentration at each new level.
