- •
Organochlorine compounds (OCs) accumulate more in egrets feeding on aquatic preys.
- •
Lower OC accumulation is found in egrets that feed on aquatic and terrestrial preys.
- •
OCs of low biomagnification potential do not show selective accumulation in egrets.
- •
The diet differences between species are confirmed with the δ13C and δ15N ratios.
- •
p,p’-DDT in cattle egret is maybe still showing influences of past agriculture use.
