air pollution is today a major problem for modern societies. it has long been recognized as a potentially lethal form of pollution. increasing pollution levels due to rapid urbanization and growth in emission related to vehicular transportation are now caused major concern. the mobilization of heavy metals into the biosphere by human activities has become an important process in the geochemical...

Soil plays an important role in the accumulation and transport of potentially toxic elements (PTEs), from surface into aquifer. PTEs can get to environment naturally, but also different kinds contamination sources. In this study, a soil profile located vicinity well field Petruševec, one most fields related public water supply City Zagreb, was analyzed. The main aim study determine properties w...

It is a well–known fact that heavy metal pollution in sediments causes serious problems not only the Danube basin, but also large and small adjacent river streams. A suitable method for assessing level of metals their toxicity calculation indices. The present research aims to assess Lower surface collected along course (between 180 60 km) up point where River flows into Delta Biosphere Reserve ...

In tropical and subtropical latitudes, woody plants known as mangroves flourish in slimy, anaerobic soils on the boundary between land sea. They can withstand extreme weather conditions like high temperatures, unreliable tides, strong winds, salt. The objective of this study was to determine concentration nine trace elements (Hf, Ga, Ba, V, Cs, Sc, Sb, Ta, Co) sediment mangrove forest along wes...

background: evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. methods: in this study, total and ...

Heavy metals in soil are a potential threat to ecosystems and human well−being. Understanding the characteristics of heavy metal pollution prediction ecological risk crucial for regional eco−environment agricultural development, especially irrigation areas. In this study, Xiaohe River Irrigation Area Loess Plateau was taken as study area, concentration, well their accumulation degree distributi...

Introduction. Urban runoff sediments contain heavy metals that generate risk to the environment. Several assessment indexes for have been developed, which show level of contamination particles in environment and their origin. Besides, sediment is also associated with particle size distribution hydrometeorological characteristics. Objective. This work seeks evaluate from collected an experimenta...

Two short sediment cores collected from mangrove areas of Manori and Thane creeks along Mumbai coast were analysed for sediment composition and metals (Fe, Mn, Cu, Pb, Co, Ni, Zn, Cr and V). The statistical analysis of Pearson correlation matrix proved that there is a significant relationship between metal concentration and finer grain size in Manori creek while poor correlation was observed in...

The main purpose of the research was to analyze distribution Arsenic (As), Cadmium (Cd), Copper (Cu), Iron (Fe), Nickel (Ni), Cobalt (Co), Mangan (Mn), and Zinc (Zn) in soft tissues, shells, associated surface sediments Cerithidea obtusa (C. obtusa) mangrove snails collected from Sungai Besar Sepang. concentration iron (Fe) found be highest relation other toxic elements sediments, shells C. obt...

Surface sediment samples were collected from different streams of Awetu Watershed in southwestern Ethiopia. Sediment analyzed for As, Cd, Cr, Pb, and Hg levels using inductively coupled plasma optical emission spectrometry. The heavy metal concentration ranged 183.60 to 1,102.80 mg/kg As (mean 623.32 ± 291.65 mg/kg), 4.40–303.20 Cd (151.09 111.5 149.20–807.20 Cr (375 212.03 485.60–3,748.80 Pb (...
