Abstract: Abstract
Light-sticks are used as bait in surface long-line fishing, to capture
swordfish and other large pelagic predators. When discharged in the
ocean, it may reach the beaches. The traditional Brazilian community of
Costa dos Coqueiros, Bahia, use light-sticks as a medicine for
rheumatism, vitiligo and mycoses. It may affect the marine life when its
content leak in the open ocean. This work evaluated and identified the
acute and chronic toxicity of the light-stick. A high acute toxicity was
observed in the mobility/mortality of Artemia sp.; in the fertilization
of sea urchin eggs, and a high chronic toxicity in the development of
the pluteus larvae of the same sea urchin. The main compounds that
probably caused toxicity were the volatiles such as the fluorescent PAH
and oxidants such as the hydrogen peroxide. Its disposal in the open
ocean is a potential threat for marine life.
