CMR products are substances recognised as carcinogenic and/or mutagenic and/or reprotoxic, meaning toxic to reproduction. Since the last world war, several million chemical molecules have been dispersed into the environment. About 100,000 chemical substances have been marketed. Of these 100,000 substances, approximately 30,000 are currently on the market. In total, about 5,000 of these chemical substances have been summarily studied from a toxicological point of view, which has led to a cursory evaluation of their impact on human health. Of these 5,000 substances, the carcinogenic properties of only a few hundred molecules (about 900) have been studied. Industrialised societies, such as our own, must therefore address multiple, multiform and diffuse chemical pollution, often unknown, which is the cause of many diseases common today. This is the theory put forward by cancer researchers at the ARTAC (Association for Research and Treatments Against Cancer). This is also why the REACH regulations aim to re-examine approximately 30,000 molecules over the next 11 years.
