The objectives of this study are to use different types of indexes to assess the current pollution status in Mengkabong lagoon and select the best index to describe the Mengkabong sediment quality. The indexes used in this study were Enrichment Factor (EF), Geo-accumulation Index (Igeo), Pollution Load Index (PLI) and Marine Sediment Pollution Index (MSPI). Different indexes give diverse status...

The lake management strategy of sediment dredging (removal) is periodically undertaken in shallow, eutrophic Mogan Lake, an important recreation area. This study aims to use certain indices - enrichment index (EF), contamination/pollution (CF), degree contamination (Cd), pollution load (PLI), geoaccumulation (Igeo), potential ecological risk (Eri), integrated (PER), and mean probable effect con...

A good understanding of urban soils metal contamination and locating their pollution sources due to industrialization and urbanization is important for addressing environmental problems. Urban soil samples near industrial locations in the Greater Toronto Area (GTA), Ontario, Canada were analyzed for metal (Cr, Mn, Fe, Ni, Cu, Zn, and Pb) contamination. Multivariate geo-statistical analysis (cor...

Introduction: Heavy metals (HMs) accumulated in the road dust may be transferred to the surrounding land and water bodies and pose ecological risks. Hence, such pollution should be considered, especially in coastal roads. This study focuses on the HMs pollution of dust settled on the surface of coastal roads along the Persian Gulf in Bandar Abbas city. Materials and Methods: In this study, ro...

This study examined the spatio-temporality of heavy metal concentrations (Al, Cd, Co, Cr, Fe, Mn, Ni, Pb and Zn) in sediments Lake Bafa, one most important wetlands Turkey’s Aegean region. The evaluated sediment quality according to threshold effect concentration (TEC) probable (PEC) values based on guidelines (SQG), provided a potential ecological risk assessment (PERI) along with indices such...

This paper examined the efficiency of artificial neural network (ANN) and multivariate linear regression (MLR) models in prediction groundwater quality parameters such as ecological risk index (ERI), pollution load (PLI), metal (MPI), Nemerow (NPI), geoaccumulation (Igeo). 40 samples were collected systematically analyzed for mainly heavy metals. Results revealed that adopting measured is effec...
