We reviewed over 226 studies dealing with arsenic (As) in water bodies (124 sites or
regions; 5,834 samples), soils (44; 2,700), sediments (56; 765), rocks (6; 85), mine waste …

Some biomolecules are well known for the complexation of heavy metals from wastewater:
cellulose, alginate, pectins, and starches for example. However, less used natural molecules …

Intensive human activities, in particular agricultural and industrial production have led to
heavy metal accumulation in the peri-urban agricultural soils of China threatening soil …

Concentrations of heavy metals in water and sediment samples of Buriganga River in the
capital city Dhaka, Bangladesh, were studied to understand the level of heavy metals and …

This study investigated the spatial distribution, contamination, potential ecological risks and
quantities of pollutant sources of six heavy metals (HMs) in sediments of 47 rivers. The …

Diffuse pollution formed during a surface runoff on paved surfaces is a source of heavy
metals (HMs) of various origin. This research study indicates the connection between bottom …

Trace elements contamination in estuarine and bay ecosystems has become a serious
problem, especially in bays with frequent aquaculture activities. To explore the pollution risk …

This study used PMF and geostatistics to quantify sources of PAHs based on 30 samples
tested for 16 PAHs in surface sediment from the Yangtze River Estuary (YRE) in February …

The study assessed the composition, health risk, and sources of trace elements of road dust
collected from three major metropolitan cities in Bangladesh. Pellets were prepared from the …

In this study, positive matrix factorization, multilinear engine 2, and geographic information
systems were used to characterize the spatial-temporal patterns of sources for nine heavy …
