Heavy Metal Contamination Detected in Chiang Rai Crops and Soil
Recent testing in Chiang Rai has identified heavy metal contamination in local crops and soil samples near major rivers, prompting further investigation.
According to a report by Prachachat Business, officials Yotchanan and Piyarat recently conducted an inspection in Chiang Rai to address concerns regarding heavy metal contamination in local water sources. The investigation involved testing 185 plant samples collected from areas surrounding the Kok, Sai, and Ruak rivers. Results indicated that five of these samples exceeded safety standards, with cadmium being the primary contaminant identified in chili peppers and eggplants. Additionally, out of 52 soil samples analyzed, 20 were classified as being in a high-risk category. For residents and travellers, these findings highlight potential food safety concerns regarding produce sourced from these specific riverbank areas. While the presence of heavy metals is a significant environmental and health indicator, the authorities have announced plans to conduct follow-up testing to confirm the extent of the contamination. At this stage, it remains to be determined how widespread the issue is across the region and what specific mitigation measures will be implemented by local agencies to ensure public safety. Residents and visitors are advised to stay informed through official government updates regarding local agricultural safety and water quality.
