| naphthalene |
Essentially two benzene rings linked together, naphthalene is a solid material derived from coal tar. It is one of two chemicals commonly used to make mothballs. It is highly toxic and in some individuals, particularly those of dark skinned races, can produce a catastrophic breakdown of red blood cells, resulting in anemia or acute kidney failure. Listed as a priority water pollutant by EPA, it bioconcentrates in aquatic organisms.
