Thanks to the progresses of science our standard of living grows, but at the same time, we introduce new potential dangers in our environment, in our food and for some people at their workstation. Understanding the chemical product, controlling it, finding preventing answers and the antidotes, that is the mission of PREVOR. Thanks to our research works, they anticipate the dangers in the modification ways that allow, without changing the interest of the products or to decrease the level of danger. We want to be the partner of everyone who wants to diminish the chemical risk in proposing new solutions to control the dangers without reducing the productivity and the advantages of the scientific progresses. We are scientists that work on the progress of the safety.
