The Dutch Toxicology Association was founded on January 18, 1979. The association currently has more than 600 members, making it one of the largest toxicological associations in Europe. The NVT is an open association: anyone working in a field related to toxicology, or following a study that trains for a position in the field of toxicology, can join as a member. The members of the association have very different backgrounds, such as biology, biochemistry, agriculture, chemistry, (animal) medicine, biomedical sciences, pharmacy or environmental science.
