Abstract

Artisanal and small-scale gold mining (ASGM) activities often pollute soil, water, and air, thereby achieving widespread proliferation, and contaminating the surrounding biota including plants. Mercury contamination on agricultural land around ASGM areas has been widely reported. This study aims to determine the total mercury contamination in plants and soil around active ASGM sites in Sukabumi Regency, Indonesia, namely, Waluran, Lengkong, and Ciemas Districts. Total mercury (Hg) content was measured from 27 plant samples (including cassava [Manihot utilisima], rice [Oryza sativa], and papaya [Carica papaya]), 7 rhizosphere soil samples, and 7 non-rhizosphere soil samples. Data were analyzed using Kruskal–Wallis test. Results showed no significant difference in total mercury concentrations among locations or plant parts, between rhizosphere and non-rhizosphere soils (p > 0.05), and among cassava plant parts, papaya, and rice. The highest mercury level was found in cassava (0.33–43.27 ppm). Mercury contamination in rice and papaya was relatively low at 0.03– 1.22 and 0.06–5.11 ppm, respectively. According to the Regulation of the Head of BPOM of the Republic of Indonesia Number 23 of 2017 concerning the Maximum Limit of Heavy Metal Contamination in Processed Food, 0.03 ppm is the maximum limit of mercury contamination in fruits, vegetables, and cereals. Therefore, all plant samples around the ASGM sites have exceeded the maximum mercury contamination and thus are not suitable for consumption.
印度尼西亚Sukabumi县手工和小规模金矿选定食用植物和土壤中的汞污染
手工和小规模金矿开采(ASGM)活动经常污染土壤、水和空气,从而实现广泛扩散,并污染周围的生物群,包括植物。ASGM地区周边农业用地汞污染已被广泛报道。本研究旨在确定印度尼西亚Sukabumi县(即Waluran、Lengkong和Ciemas地区)ASGM活跃场地周围植物和土壤中的总汞污染。测定了27个植物样品(包括木薯[Manihot utilisima]、水稻[Oryza sativa]和木瓜[Carica papaya])、7个根际土壤样品和7个非根际土壤样品的总汞(Hg)含量。数据分析采用Kruskal-Wallis检验。结果表明,总汞浓度在不同地点、不同植物部位、根际土壤与非根际土壤之间以及木薯、木瓜和水稻之间均无显著差异(p > 0.05)。木薯的汞含量最高(0.33-43.27 ppm)。水稻和木瓜的汞污染相对较低,分别为0.03 ~ 1.22 ppm和0.06 ~ 5.11 ppm。根据印度尼西亚共和国BPOM负责人关于加工食品中重金属污染最高限量的2017年第23号条例,0.03 ppm是水果、蔬菜和谷物中汞污染的最高限量。因此,ASGM场址周围的所有植物样本均已超过最高汞污染水平,因此不适合食用。
