The aim of our study is to determine the hyperaccumulatory properties by examining heavy metal accumulation (Co, Ni, Fe) in endemic Anchusa leptophlla subsp. tomentosa, Alyssum pateri pateri, Glaucium acutidentatum and non Erysimum uncinatifolium species collected from a copper mining area Elazığ Maden district. All are hyperaccumulator according their Bioconcentration Factor (BCF) values Co el...

in this study, the mineralogical composition and concentration of heavy metals in surfacesediment of north west persian gulf (musa estuary and hendijan coastline) were investigated. fifteensampling sites were selected and the sediment samples were collected using peterson grab sampler in august2013. xrd analyses demonstrated that the sediments of study area are principally composed of calcite,q...

With the rapid development of economy, heavy metal soil pollution causes ecosystem deterioration and raises serious concerns. Topsoil samples (n = 205) were collected to investigate characteristics, risk levels, sources metals in topsoil eastern Tibet. Heavy contents, such as As, Hg, Pb, Cr, Mn, Mo, Ni, Cu, Zn, Cd, tested, potential analyzed using correlational principal component analysis. The...

water and sediment samples were collected from six different stations, located along the nil river between february and june 2015. concentrations of cadmium, lead, zinc, and copper were determined. the extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (cf), pollution load index (pli), and the geoaccumulation index (igeo). the result...

As a primary sink of pollutants, urban soil heavy metal pollution and its influence on residents ecosystems has been becoming one the most important environmental problems. In present study, four indices, Geoaccumulation index (Igeo), improved Nemerow (IMN), degree contamination (mCd), security (CSI), as well potential ecological risk (RI), were used to evaluate individual or integrated for sam...

The concentration and distribution of trace metals were determined in sediment cores from the Khuan Khi Sian wetland, Thailand. collected seven stations dry wet seasons 2022. Pb, As, Cd season range 0.00–60.16, 0.00–6.68, 0.00–0.92 mg/kg (dry weight), respectively. Meanwhile, 0.00–12.12, 0.00–3.86, vertical profiles metal concentrations core show a general increase bottom to top. Average heavy ...

Phân tích dạng hóa học của nguyên tố Mangan là cần thiết để đánh giá mức độ ô nhiễm trong đất ở các khu vực khai thác khoáng sản. Trong nghiên cứu này, nồng mẫu được xác định bằng phương pháp quang phổ khối plasma cảm ứng cao tần. Nghiên này cũng áp dụng quy trình chiết liên tục Tessier hoá bãi thải và nông nghiệp gần thãi mỏ chì/kẽm làng Hích, huyện Đồng Hỷ, tỉnh Thái Nguyên. Kết quả cho thấy,...
