Oil and pollutants resulting from its extraction and exploitation are considered as one of the serious problems for human health. Vast oil fields of Ahvaz City located in southern Iran are known as one of controversial subjects in contamination with heavy metals. In this study, oil fields' soils of Ahvaz city (Ab-Teymour) were chemically analyzed in order to determine the concentration of eight...

eight selected heavy metals (cu, zn, pb, cd, cr, mn, fe and al) in surface and sub-surfacesediments in the northern coast of sfax (tunisia) were studied in order to assess the sediment quality and tohighlight the anthropogenic contributions to heavy metal distributions in the two study sediment levels.multiple chemometric approaches based on geographic information system (gis), enrichment facto...

Human activities around or within national highways, combined with atmospheric mixing, produce road dust, which can cause health problems through a variety of exposure routes. Thus, the study was aimed to investigate contamination, spatial distribution, potential ecological and human risks various toxic heavy metals such as lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd), zinc (Zn), nickel ...

Kadmium (Cd) merupakan logam berat berbahaya yang dapat mengakibatkan terjadinya pencemaran di perairan. Penelitian ini bertujuan untuk mengetahui kandungan Cd pada matriks air, sedimen, dan ikan nilem (O. hasselti) Sungai Tajum, Banyumas serta tingkat berdasarkan Single Pollution Index (Pi), Contamination Factor (CF), of Geoaccumulation (Igeo), Bioaccumulation (BAF), Estimated Daily Intake (ED...

Ag và Sn tuy không được xếp vào loại độc hại nhưng cả hai đều có những tác động tiềm ẩn đối với môi trường, hệ sinh thái vì thế việc kiểm soát đánh giá mức độ ô nhiễm của chúng vẫn rất cần thiết, đặc biệt ngày nay khai thác khoáng sản, vật liệu nano càng phát triển dẫn tới giải phóng ra lượng Ag, nhiều. Do đó, nghiên cứu này tập trung kim trong trầm tích sông Cầu – Thái Nguyên. Các dạng liên kế...

This paper provides an overview of different methods assessing the trace metal (TM) contamination status sediments affected by anthropogenic interference. The geochemical background determination are also described. A total 25 papers covering rivers, lakes, and retention tanks in areas subjected to pressure from last three years (2019, 2020, 2021) were analysed support our examination assessmen...

Pawara area is a mining district in the eastern region of Cameroon. Mining generally artisanal and semi-mechanized, practiced by local miners immigrants from neighboring African countries China. The lack strict regulations control activities permits to use illegal substances, especially Hg gold separation. These expose toxic heavy metals pollution. This study highlights source concentration soi...

Diffuse water pollution from agriculture (DWPA) is one of the major factors causing in Lakes Palić and Ludaš, two largest shallow lakes Pannonian Basin Serbia. These are protected under national international law. On basis number strictly bird species, Ludaš Lake has been classified as a wetland importance since 1977 (Ramsar site 3YU002); 2021, both were nominated potential Natura 2000 areas. D...

lead as non-essential metal, is known the source of toxicity and impacts on the environment and humans. the goal of recent paper is to determine the pb concentration of road and road margin dust of ghamishlu wildlife refuge in isfahan province with an area about 120,000 hectares surrounded by four main roads. traffic load in the southern freeway have been reported as about 3600-19000 cars/day. ...
