Dechlorane Plus in eggs of two gull species (Larus michahellis and Larus audouinii) from the south-western Mediterranean Sea

Dechlorane Plus (DP) and some of its possible degradation products were measured in eggs from the yellow-legged gull (Larus michahellis) and Audouin's gull (Larus audouinii) from a protected area in the southwestern Mediterranean Sea. Statistically significant differences were found between bot...
