Potential toxic element accumulation in soils and plants is one of the leading environmental problems in recent years. In many countries, mining enterprises are generally abandoned for reasons such as increasing costs, depleted reserves, and changes in ore quality. The negative effects on the environment during or as a result of these activities are known. The focus is on investigating the Hg concentration accumulated in the soil and plants around the abandoned mercury quarry located in the north-west Black Sea region (Tezcan Hg Mine). While the distribution of Hg and As is observed toward the downward slope in the mining area, it has been observed that it decreases as it moves away from the source area. The relationship of Hg concentration with granite intrusions in the areas of upward slope and topographic barriers is due to the alteration of the hydrothermal phase mineralizations and the accumulation of ore rocks. According to the Geoaccumulation Index in the lands around the abandoned mercury quarry in the Northwest Black Sea region, AsIgeo and HgIgeo accumulation are found as extremely; according to contamination factor, CFAs and CFHg values are found as very high; according to enrichment factor, EFAs and EFHg are found as extremely high; according to the Potential Ecological Risk Factor, As and Hg are found as very risky, and according to the Pollution Load Index, they are found as Pollution. As well as in soils, As and Hg concentrations were determined in Mentha longifolia (L.) L. subsp. typhoides (Briq.) Harley (dere nanesi) from the Lamiaceae (Turkish name: Ballıbabagiller) family, Taraxacum buttleri Van Soest (karahindiba) from the Asteraceae (Turkish name: Papatyagiller) family, Plantago lanceolata L. (damarlıca) from Plantaginaceae (Turkish name: Sinirotugiller) family, and Pyracantha coccinea M. Roem. (ateşdikeni) from the Rosaceae (Turkish name: Gülgiller) family, which were collected from the same locations. According to 207Pb/206Pb—208Pb/206Pb, the origin of lead in the soils within the enterprise is of geogenic origin, and according to the results of 87Sr/86Sr—143Nd/144Nd, it is thought that the samples examined are caused by granitoid.

黑海西北部(土耳其)废弃汞采石场土壤中 Nb-Sr-Pb 同位素分析、土壤和植物地球化学、生态风险评估及其对人类健康的影响

土壤和植物中潜在的有毒元素积累是近年来主要的环境问题之一。在许多国家,矿山企业普遍因成本增加、储量枯竭、矿石质量变化等原因而被放弃。在这些活动期间或由于这些活动对环境的负面影响是已知的。重点是调查黑海西北部地区废弃汞采石场(特兹坎汞矿)周围土壤和植物中积累的汞浓度。虽然观察到 Hg 和 As 的分布是朝着矿区下坡的,但已经观察到它随着远离源区而减少。上坡和地形障碍区的Hg浓度与花岗岩侵入体的关系是由于热液相矿化的改变和矿岩的堆积。根据黑海西北部地区废弃汞采石场周围土地的地质积累指数,AsI发现geo和 HgI geo积累非常多;根据污染因子,发现 CF As和 CF Hg值非常高;根据富集因子,EF As和 EF Hg极高;根据潜在生态风险因子,As 和 Hg 被认为是非常危险的,而根据污染负荷指数,它们被认为是污染。与土壤一样,在长叶薄荷(L.) L. subsp.中测定了 As 和 Hg 浓度。伤寒(Briq.) Harley (dere nanesi) 来自唇形科(土耳其语名称:Ballıbabagiller)家族,Taraxacum buttleri Van来自菊科(土耳其名称:Papatyagiller)科的 Soest(karahindiba)、来自车前草科(土耳其名称:Sinirotugiller)的车前草 (Damarlıca) 和Pyracantha coccinea M. Roem。(ateşdikeni) 来自蔷薇科(土耳其名称:Gülgiller)家族,它们是从同一地点采集的。根据207 Pb/ 206 Pb— 208 Pb/ 206 Pb,企业内部土壤中铅的来源为地源成因,根据87 Sr/ 86 Sr— 143 Nd/ 144 Nd的结果认为检查的样品是由花岗岩引起的。
