Raptors are still affected by environmental pollutants:Greenlandic Peregrines will not have normal eggshell thickness until 2034
The DDT-induced effects, eggshell thinning and breeding failure in Peregrine Falcon populations, were reverted with restrictions on the use of the compound from the 1970’ies, and in most studied populations the eggshell thickness is back to normal. In Greenland, a previous study of eggshell thinning...

The DDT-induced effects, eggshell thinning and breeding failure in Peregrine Falcon populations, were reverted with restrictions on the use of the compound from the 1970’ies, and in most studied populations the eggshell thickness is back to normal.
