Summary: Our previous show on copper-based bottom paints featured the coatings-industry point of view. In this segment, we’ll find out more about the environmental issues that are leading to bans on the west coast. Our guest, Nan Singhasemanon (California State Department of Pesticide Regulation), will fill us in on the current status of new legislation and why the regulations have so many supporters. We’ll also find out more about how coatings can prevent the growth of barnacles, algae, and other marine organisms, and we’ll find out what environmental concerns are associated with copper-based paint. Finally, we’ll discuss what California has already done to reduce copper contamination, and we’ll talk about existing and upcoming alternatives to copper-based paint.
