The concentrations of endocrine disruptors were determined in 36 liver tissue, serum and whole blood sample extracts drawn from 15 Blue Lagoon National Park Kafue lechwe. Out of 10 analytes evaluated, 89% of the sample extracts showed very high dieldrin concentrations of between 0.08-100 μg/mL in serum, 0.08-24.8 μg/mL in whole blood and 0.08-4.6 μg/g wet weight in liver tissue extracts. pp-DDE was detected in 83% of the sample extracts at 0.006-5.1 μg/mL in serum, 0.006-8.5 μg/mL in whole blood and 0.006-0.12 μg/g wet weight in liver tissue extracts. There was strong correlation between pp-DDE and dieldrin in all the three matrices. Deltamethrin and endosulfan detected at 50% frequency each. Percent recoveries in spiked laboratory blanks ranged between 60-100% while calculated detection limits ranged from 0.004 to 0.21 μg/mL for all the endocrine disruptors evaluated. © 2009 Springer Science+Business Media, LLC.
