The safety of the environment and the quality of our own health are important. The growth of the global population and an increasing industrialization are key factors putting pressure on the environment and, in that way, threatening our health. In our research we address in particular the risks of chemicals that are being produced in increasing volumes to satisfy the needs of the growing world population. Although these chemicals often serve useful purposes such as lower energy costs, cleaner materials, fire safety and faster transport, they are often harmful to the environment and the human body. They can bioaccumulate, cause cancer, disrupt hormonal processes, and weaken the immune system of organisms. We develop methods for their analysis, study their environmental fate, test their toxicity, advise authorities, train other laboratories in measuring them, and teach young people in this highly specialized work.
