Abstract :
[en] Despite their common occurrence in Guadeloupe, little is known
about levels and effects of pollutants in free-ranging green (Chelonia
mydas) and hawksbill (Eretmochelys imbricata) turtles. The aims of this
study were 1) to evaluate levels of persistent organic pollutants and
trace elements in Guadeloupian marine turtles, 2) to assess the risk for
turtle embryo facing chemical exposure. Eggs
and dermis were collected from 11 green and 4 hawksbill turtles and
analysed for inorganic and organic pollutants. Chemical risks were
evaluated for turtle embryos through a screening risk assessment (SRA).
ΣPCBs and chlordecone were the main contaminant groups in green and
hawksbill turtles. Contaminant levels were lower in the Guadeloupean
populations than in the other ones. p,p'-DDE, selenium, mercury and
cadmium could affected the marine turtle embryos. This study is the
first to provide levels of pollutants in marine turtles from Guadeloupe.
