Some Organochlorine Pesticides (OCPs) can pose numerous adverse effects on biota. Marine turtles face numerous threats, in particular those related to anthropogenic activities. Therefore, development and improvement methodologies for monitoring chemical compounds are a relevant task. In this work, we developed a methodology based on the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction for detection of twelve OCPs, by gas chromatography with electron capture detector, in fat and liver samples of green sea turtles. Quantification limits were lower than 5.3 ng g-1; acceptable recovery rates for most compounds; medium matrix effect; matrix-calibration with linearity at the range from 1.0 to 200 ng g-1. This methodology provides contributions for the study of pesticide residues with adverse effects on sea turtle health, important skills for new directions in conservation issues.
