Chemicals are everywhere: in the air we breathe, in the food we eat, in the water we drink, in the cosmetics we use, the shoes we wear or in the toys with which our children play with. Chemicals are part of our daily lives and we are not always aware of how they affect us. Many everyday life products have not been adequately tested and hence pose a serious health. As a result, they can have severe impacts on our health and there is a worrying increase in health problems due to the use of chemicals. The current assessments of chemicals are usually based on the evaluation of single substances, chemical by chemical, looking at how they affect us, but they do not provide us with sufficient security and hence remain dangerous.
