The impact of heavy metal contamination caused by human activities on mangroves, rivers, estuaries, and coastal wetlands has gained attention recently. In this study, the presence metals in mangrove Sepang Besar River's surface sediments was examined. As, Mo, Pb, Cr, Co, Cd, Ni, Hg concentrations sand were measured using inductively coupled plasma mass spectrometry (ICP-MS). Across all sampling...

background: evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. methods: in this study, total and ...

The current study was conducted on the valley of Duhok and agricultural lands irrigated from it, where three sites were identified for collecting samples quarterly soil sediment using clean plastic bags purpose measuring lead, nickel, cobalt copper. Pollution load index (PLI), Nemerow pollution (PIN), Potential Ecological Risk (PER) Geo-accumulation Index (Igeo) also calculated according to int...

This research intends to offer a scientific foundation for environmental monitoring and early warning which will aid in the protection management of Qaroun Lake. Lake is increasingly influenced by untreated wastewater discharge from many anthropogenic activities, making it vulnerable pollution. For that, six pollution indices, namely contamination factor (Cf), enrichment (EF), geo-accumulation ...

In the recent years, agricultural soils have received more chemicals in various forms for higher yields. This may result in the accumulation of metals in soils which subsequently may be transferred into the agricultural crops. In the present investigation, nickel content of 58 composite soil samples and also agricultural crops, is studied. Ni in samples of soil and agricultural products were ex...

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...

The uncontrollable population growth is reaching Benin's rivers, especially the coastal lagoon, raising then thorny problem of pollution, which considerably accentuated by malevolent behavior populations. aim this paper to characterize degree contamination water and sediments lagoon in heavy metals (Cd, Cr, Zn, Cu, Pb Fe) through dosage with molecular absorption spectrophotometer type DR 3900. ...
