From September 6th to September 9th, 2021, we participated in the 13th EMECS Conference.

This conference was held at ONLINE LIVE and On-demand due to the influence of the global epidemic of the new coronavirus.

We made an online presentation entitled "Combined Effects of Organotin Alternative Antifouling Biocides (Sea-Nine 211, Diuron, Irgarol 1051) on Sea Urchins". It was shown that the presence of multiple organotin alternative antifouling biocides is more toxic to sea urchins than when used separately. In particular, Irgarol 1051 was found to have a more combined effect than Diuron in the low concentration range (1 µg / l to 5 µg / l).

We will continue to conduct surveys and research on the environment and make presentations.
