Constructed wetlands are an affordable and reliable green alternative to conventional mechanical systems for treating domestic sewage. This study investigates the potential of 14 tropical wetland plant species removing heavy metals from sewage through bioconcentration factor (BCF), translocation (TF), enrichment (EF), geoaccumulation index (Igeo) using batch mesocosm studies. Plants with BCF &g...

Coastal aquatic ecosystems are environments increasingly affected by human activities due to urban discharges and their use as dumps. The objective of this study is determine the profiles metallic elements concentration (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Pb) Cotonou channel sediments evaluate quality. For this, surface (0-5cm) were sampled at 13 sites along channel. Thus,Geoaccumulation I...

Selected heavy metals (Cr, Cu, Ni, Pb and Zn) in surface sediments from the coastal Shandong Peninsula (Yellow Sea) have been determined to evaluate the spatial distribution and potential ecological risk. Results showed that heavy metal concentrations in the sediments generally met the criteria of China Marine Sediment Quality. However, both the enrichment factor (EF) and geoaccumulation index ...

increasing in concentration of heavy metals such as lead, cadmium, nickel, chromium and zinc cause considerable harmful effects on soil and environment. these elements are also hazardous to health of humans and wildlife. petrochemical plants and refineries pollution increase the amount of carcinogenic and tratogenic compounds in environment. the main goal of recent paper is the studying of soil...

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 ...

The Al-Salam Lagoon is one of the recreational sites along Jeddah coast, showing environmental impacts urbanization coast. A sediment core (220 cm) was collected from intertidal zone to evaluate heavy metals (Fe, Mn, Cr, Ni, Cu, Zn, and Pb) geochemical indices (contamination factor, geo-accumulation index, pollution load index). In organ-ic-rich muddy sediments (0–100 cm), there a high content ...

The goal of this research is to assess hazardous heavy metal levels in PM2.5 fractioned road dust order quantify the risk inhalation and potential health effects. To accomplish this, Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was used determine concentrations eight metals (Cr, Cu, Ni, Zn, Cd, As, Pb, Hg) portion samples from five different land use areas (commercial, residential, ind...

The main objective of the present study is to assess level contamination, source identification, and health risk assessment heavy metals in industrial soils Aurangabad. A total 15 Soil samples were collected with a sampling density 3–5 composite soil from 0–10 cm surface soil, analyzed (Ni, Pb, Cd, Zn, Cr, Mn, Fe, Cu) using atomic absorption spectroscopy. geographical information system (GIS) t...
