High dioxin concentrations and mortality of embryos in eggs of Dutch songbirds
Wednesday, May 16, 2012
A new study of the Bargerveen Foundation shows that the eggs of meadow pipits and wheatears have high dioxin doses. These toxins may cause the embryonic abnormalities which the study found, but further research is needed.
The research has focused on two Dutch nature reserves: the North Holland Dune Reserve and Aekingerzand, a drift sand area in Drenthe. The dioxins in the eggs are probably from insects which get these toxins from the soil. The first results are published this week in the Vakblad voor Natuur, Bos en Landschap.
Because dioxins are spread through the air, the researchers expect that songbirds in many more places than previously thought are exposed to the consequences of dioxin poisoning.
Dioxins are mainly released from combustion processes, for example in industry and traffic.
