VII. Chemicals in the Marine Environment

 Of the many chemicals produced and used in human activities, some have harmful effects on people and wild animals. At the MERI, we not only study the impact of these chemicals on the survival and reproductive capacity of marine organisms from the standpoint of environmental conservation and marine species protection, but we also are developing testing methods to evaluate their toxicity. So far, we have studied the impact of endocrine disruptors on marine organisms as well as the bioaccumulation of dioxins in seafood across the country, and have developed biological monitoring methods to evaluate the concentration of chemicals and the state of pollutants in the ocean. Furthermore, we have also investigated experimental methods for studying the impact of chemicals on the maturation and early life-stage development of Japanese whiting as well as acute impacts on zooplankton including Tigriopus copepods and have developed methods for studying reproductive impacts, all with the objective of assessing the environmental risk of certain chemicals.
