Red Sea coastal development has rapidly accelerated in recent decades that led to a rise the anthropogenic heavy metal levels sediments. A total of 80 surficial sediment samples were collected from shallow waters along eastern coast near Jeddah, Saudi Arabia. These three locations, designated as North, Middle and South assess concentrations six metals: chromium (Cr), manganese (Mn), nickel (Ni)...

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...

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...

Global water shortage is caused not just by the physical scarcity of water, but also gradual deterioration quality resources such as lakes, streams and rivers with heavy metals. This present study evaluated status Mn, Fe, Cr, Cu, Ni, As, Zn, Pb Cd in sediments from lower Orange River Inductively Coupled Plasma Atomic Emission Spectrometry technique collecting a total eleven samples, each weighi...

A study has been conducted to evaluate the degree of Heavy Metals (HM)contamination on farm soils Wakwa’s, using enrichment factor (EF), geo-accumulation index (Igeo), pollution load (PLI), Ecological risk factors (Eir), indices(PER) and statistical analysis.In currentstudy, composite surface agricultural soil samples were collected in 4 sites analyzed for concentration HMs including As, Ba, Co...

Bu çalışmada, İstanbul ilinin yapım yılları farklı iki otoyolu olan, E80 Tem Otoyolu ve Kuzey Marmara Otoyolu’nun bölgelerinden alınan 36 adet toprak numunesinin inorganik element konsantrasyonlarının belirlenmesi, ayrıca kirlilik faktörü (CF) jeo-birikim (Igeo) indeksi hesaplamaları yapılarak, çevre toksikolojisi halk sağlığı çerçevesinde değerlendirilmesi amaçlanmıştır. Indüktif Eşleşmiş Plaz...
