Toxic paint
 

Many marine paints contain metallic compounds to keep barnacles and
algae away, but those compounds can leech into the water killing a wide
variety of marine animals. Now,
University of Florida researchers have created a new paint additive
using natural compounds from a marine worm. These compounds could be
useful as additives to marine paints because they affect the
chemo-receptors that may help the barnacle larvae find a marine surface
to settle on. Take a look at this report about toxic paint, this isn't
