due to the lack of water quality of resourses in country, exact review of available water resources quality, especially in terms of heavy elements (heavy metals) has a particular importance. due to industrial towns 1 and 2 of yasuj city and also yasuj wastewater treatment, surveying environmental harmful effects of heavy metals on this river is very important. to investigate the changes of heav...

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...

Fresh water scarcity is considered a significant component, and potentially one of the most critical, global climate change. With rapid development industry, there an increasing risk freshwater contamination by heavy metals (HMs). The danger HM pollution also attributed to their accumulation, which can subsequently become source secondary in aquatic environments. In Lake Gusinoe basin, located ...

The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

Core sediment (sapropel) samples were collected from Lake Okunozero, the Republic of Karelia, Russia, to assess distribution heavy metals and their main fractions, probable sources pollution, potential ecological toxicological risks for water body. Heavy metal concentrations measured by mass spectrometry method using an XSeries-2 ICP-MS. The sequential extraction sapropel was performed scheme T...

Soil samples in Moryayla village located 156 km northeast of Erzurum and Cu mineralization area around it were collected randomly. In these samples, 20 taken order to investigate the metals found pollution limits sources that cause this pollution. The geochemical analyzes (Cd, Cr, Cu, Ni, Pb, Zn Fe) soil made evaluated with parameters. calculation parameters, enrichment factor (EF); geoaccumula...

introduction we can obtain useful information about aquatic systems by studying heavy metals in surface sediments. marine sediments can bring out the aquatic contamination. due to heavy metal toxicity, hard biodegradation and easy bioaccumulation in aquatic ecosystems, various indices have been developed such as sediment quality guidelines (sqgs), enrichment factor (ef), pollution load index (i...
