This is slightlylower than the NOEC of 2.5 ppm(2.5 mg/kg) for eggshell thinning in ducks as reported in the original report.
The effects include cancer, death, eggshell thinning, population declines, reduced hatching success, abnormal behaviour, changes in organ development, infertility, birth defects and a range of other illnesses.
According to the OSPAR document on dicofol(Ref. 9),the pattern and magnitude of dicofol on eggshell thinning was similar as that observed with p, p ' -DDE.
Long-term effects are eggshell thinning, with effects on reproduction(Van Rijn et al., 1995). In ducks, effects on eggshell strength were found in dietary studies(126 days) starting from 2.5 mg/kg dicofol.
This is slightly lower than the NOEC of 2.5 mg/kg for eggshell thinning in ducks reported by Belfroid A. et al.(2005)(Ref.1);
In addition,further experiments revealed effects on the reproduction of owls and pigeons where eggshell thinning at a concentration of 3 mg/kg feed was demonstrated.
Wiemeyer et al.(2001)reported that the lowest observed dietary effect concentration for eggshell thinning was 3 mg/kg and that the no observed adverse effect concentration(NOAEC) was 1 μg/g(Ref. 11).
Besides these effects, data from laboratory studies with Japanese quail and American kestrels indicate that HBCD atenvironmentally relevant doses could cause eggshell thinning, reduced egg production, reduced egg quality and reduced fitness of hatchlings.
You're skating on thin eggshells right now.
