[The Hwankyung Ilbo] Most of the mass strandings of wild birds (more than 2 birds in the same area, average 20 birds) occurred in the past year were caused by pesticides.
According to a research by the National Institute of Environmental Research (NIER) that analyzed 32 mass strandings (633 birds) of wild birds happened from January 2017 until recently, 28 cases (566 birds) out of 32 were caused by pesticides.
The cause analysis of 32 cases found that bird flu viruses were found to be negative, but agricultural chemicals used for pesticide were detected in the 566 birds.
In the remaining 4 cases (67 birds), the pesticide component was not found and the obvious cause of death was not identified. The researchers estimated that they were common deaths caused by sickness, starvation and accident.
Pesticide compounds above lethal dose were detected in the rice seeds found in the stomach of most of the birds’ body except the 4 cases.
NIER said “it is illegal to intentionally spray the seeds covered with pesticides with the purpose of killing wild birds, that is banned by the ‘Wildlife Protection and Management Act’.”
The institute is planning to reinforce equipment and manpower from this year in an attempt to analyze the pesticide compositions of most of the mass strandings that occur simultaneously in two or more birds.
