High levels of dioxins found in chicken eggs sampled near waste incinerators and metallurgical plant in China

(Beijing, China) High levels of dioxins and similar dangerous pollutants were found in free range chicken eggs samples taken close to waste incinerators and other industrial hot spots in six localities in China, according to a new study released today. Chicken eggs are an important part of the Chinese diet, and the study warned that contamination found in the egg samples represents a serious threat to the public health of populations living in these locations.

Dioxins are dangerous in extremely small concentrations, and they cause neurobehavioral disorders, have a negative impact on the body’s system for regulating hormones (endocrine system), and some are human carcinogens.

“The way to prevent human exposure to toxic chemicals in China is to prevent dioxin releases at waste management sites and put in place better emissions control in metallurgical plants– not to stop eating free range eggs,” says Mao Da from Chinese NGO Insight Explorer.

IPEN (an international network), Arnika Association (Czech Republic) and Insight Explorer (Beijing, China) conducted the survey of free range chicken eggs in the vicinity of several industrial sites in China, which are potential hot spots for persistent toxic chemicals. High levels of very toxic and very persistent dioxins and PCBs were found in samples taken close to waste incinerators and one metallurgical plant, while low levels were found in egg sample from a supermarket in Beijing.

The presence of a very high level of brominated dioxins in eggs collected near a municipal waste incinerator in Wuhan shows serious contamination most likely caused by inappropriate handling (burning) of e-waste containing high levels of brominated flame retardants.

According to the report, the high levels of dioxins and other persistent pollutants in free range chicken eggs from the vicinity of several waste incinerators underline the need to 1) increase non-toxic waste recycling in China instead of massive building of new large waste incinerators, and 2) tighten the control of management of waste incineration residues and other unintentional toxic releases from waste incineration.

 “Preference should be given to waste minimization and waste recycling in agreement with the Stockholm Convention which China ratified. At the same time, import of e-waste containing high volumes of toxic chemicals to China should be avoided. Recycling of non-toxic waste is a more environmentally friendly approach to waste management than building waste-to-energy plants and incinerators,” says Jindrich Petrlik, co-chair of Dioxin, PCBs and Waste Working Group of IPEN and chairman of Arnika Association.

The data and analyses of free range chicken eggs were obtained from local people and/or sampled by Chinese NGOs Insight Explorer and Green Beagle during field visits in 2013, 2014, and 2015 from six different industrial localities in China and one sample of eggs from a supermarket in Beijing for comparison. These locations were: Beihai, Guangzhou, Wuhan, Qiqihaer, Ziyang, and Shenzhen. Eggs are an important exposure pathway from soil pollution to humans, and eggs from contaminated areas can readily lead to high pollution exposures.
