Data dealing with the assessment of heavy metal pollution in road dusts in Jeddah, Saudi Arabia and its implication to human health risk of human exposure to heavy metals, are scarce. Road dusts were collected from five different functional areas (traffic areas (TA), parking areas (PA), residential areas (RA), mixed residential commercial areas (MCRA) and suburban areas (SA)) in Jeddah and one ...

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 ...

When residents of Volos, a city in central Greece, are trying to recall their daily life after the end quarantine due COVID-19, soil pollution survey provided valuable insights, which compared with 4-year study carried out that area before pandemic period. Using appropriate indices, namely contamination factor (CF), load index (PLI), geo-accumulation (Igeo), ecological risk (Er), and potential ...

The increasing industrial activities, number of vehicles on road and population in large cities causes the contamination air urban environment, eventually affect human health. Therefore, aim this study was to collect soil dust samples from twelve roadside academic institutions Dhaka City, Bangladesh. One sites is control site for study. elemental (Ca, Fe, K, Ti, Sr, Zn, Zr, Rb, Cr, Ni, Pb Cu) c...

Soil pollution refers to the contamination of soil by harmful substances that can have adverse effects on plant and animal life, it also negative affects health-being humans. The sources include industrial activities, agricultural practices, mining transportation activities. contaminants in heavy metals, pesticides, herbicides, fertilizers, petroleum products, other chemicals. These seep into a...

Spatial concentrations and chemical fractions of heavy metals (Cr, Cu, Pb, Zn and Cd) in 16 sampling sites from the Honghu Lake were investigated using an atomic absorption spectrophotometer and optimized BCR (the European Community Bureau of Reference) three-stage extraction procedure. Compared with the corresponding probable effect levels (PELs), adverse biological effects of the studied five...

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...

Mining is an activity that involves the use of chemicals and results in unsustainable dangerous conditions for miners, their families, community surrounding ecosystem. This study was done to assess metallic contamination soils sediments Bétaré-Oya gold artisanal mine district, East-Cameroon. A total thirty (30) samples exploited soils, control were taken from mining sites Lom, Mbal Mali. The co...
