Environmental Experts Investigate Toxic E-waste Dump in Kalasin






An international team of experts are investigating the industrial hot spots in Khok Sa-ad sub district, Kalasin province. The area is infamous for Thailand’s largest e-waste dump, where scrap from all over the world was formerly collected. The toxic pollution is even enhanced by local dubious dismantling and recycling sites affecting its wider vicinity, including poor local communities. Environmentalists from Arnika [1], EARTH [2], and the local administrative organisation are collecting samples for analysis of toxic chemicals.

Heavy metals, brominated flame retardants (BFRs), or persistent organic pollutants (POPs) are the main suspects of dangerous pollution causing severe health and economic struggles to the villagers of Khok Sa-ad, located approximately 400 km north-east of Bangkok. 

‘The e-waste recycling treatment here lacks any sort of medical or environmental precautions; the scrap is often burned on an open fire in order to obtain valuable metal parts. This leads to poisoning not only for the workers but also for everyone and everything in the area,’ explains Jindrich Petrlik, Arnika’s expert on toxic substances. 

Their team will collect samples of soil, dust, water, and eggs to be analysed in the laboratory. The goal is determining the current levels of contamination with persistent organic pollutants (PBDD/Fs, PCDD/Fs, PBDEs, and dioxins). These chemicals have a serious effect on the human immune and reproductive system.  Previous research has already shown serious contamination with heavy metals.

According to the executive director of EARTH, Penchom Saetang, ‘the e-waste workers of Khok Sa-ad may be facing serious health threats, even if some of them do not know it. In the premises we visited, workers wore only basic personal protection equipment – gloves and facecloths. Villagers from within a 2-km radius also complain because of acrid smoke and breathing problems. This research will show whether waste burning and recycling are the cause,’ says the main figure of the environmental protection and justice movement in Thailand.

For years, the e-waste has been supplied from countries around the world as Thailand lacks effective legislation on waste import and management. Experts suggest that the key solution, not only to this case but also others, is the crucially awaited amendment to the Basel Convention [3], which would put an end to such practices and finally protect vulnerable communities across the globe.
