Heavy metal contamination of sediment obtained at sea shore downstream of Dumpsite of Qaanaaq village, Greenland, conducted in 2023.

In 2022, 30 soil samples were obtained in dumpsite of Qaanaaq village. Soils were brought back to the laboratory and were subjected to Japan leaching test No. 46 which is official test for evaluating soil contamination of heavy metals. Soil was mixed with distilled water at liquid to solid raton was 10, then the mixture was shaken for 6 hours. After shaking, mixture was filtrated. Heavy metal concentration of filtrate was analyzed by atomic absorption spectrometry.2022年，研究人员在卡纳克（Qaanaaq）村的垃圾场采集了30份土壤样品。采集所得土壤被运回实验室，开展用于评估土壤重金属污染的官方标准试验——日本第46号浸出试验。具体试验流程如下：将土壤与蒸馏水按液固比10混合，随后将该混合体系振荡6小时；振荡结束后，对混合物进行过滤。最后采用原子吸收光谱法对滤液中的重金属浓度进行分析测定。
