The contamination of riverbed sediments by heavy metals has assumedserious problems due to their toxicity and accumulative behavior. The present studyinvestigated the concentrations of heavy metals from the bottom sediments of ShitalakhyaRiver to understand the level of contamination and their distribution. The averageconcentrations of heavy metals Al, K, Ca, Mg, Fe, As, Cu, Co, Cr, and Zn are ...

This is a preliminary report on total mercury (THg) in core sediments (\63 lm particle size) of Sunderban mangrove wetland, northeastern part of the Bay of Bengal, India. Cold vapor atomic absorption spectrometry (CVAAS) was used for THg determination. The concentration varies from 9.8 to 535.1 ppb (ngg). Results revealed variations over premonsoon and postmonsoon month at different core depth,...

Coastal environmental assessment techniques have evolved into one of the most important fields for long-term development and management coastal zones. So, overall aim present investigation was to provide effective approaches making informed decisions about Gamasa coast sediment quality. Over a two-year investigation, samples were meticulously collected from estuary littoral shelf. The inductive...

Heavy metal (Pb, Zn, Cu, Cr, Ni, Mn and Cd) concentrations were investigated for the first time in core sediments of the Municipal Lake of Yaounde, Cameroon. The area under study receives domestic raw sewage from surrounding populated neighborhoods through River Mingoa, main tributary of the lake. Other activities like automobile service stations, garages, non operational effluent treatment sta...

The river Nile is a dominating physical feature of the northeastern part of the African continent, covering areas exhibiting varieties and contrasts in topography, climate vegetation and people. So, in this study, we estimated the contamination of the Nile sediment with some major and trace heavy metals in core samples which can cause some undesirable health effects. Concentrations of all eleme...

In Poland’s largest mining district, the Upper Silesian Coal Basin, there is a growing interest in resource development by small operators. Some concession areas are not yet directly affected industry. The objects of this research two such and goal to determine load heavy metals (HM) soils prior projects assess extent their contamination at stage. studied were Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn, wh...

One of the most effective nature conservation measures is creation territories where human impact limited, this called specially protected natural areas. A significant contribution to increasing area Russian Federation covered by areas was made State Nature Reserve in Leningrad Region, known as “East Gulf Finland”. Initially, reserve supposed include island Gogland (but it now not part area). T...

The present research was carried out to examine the health and environmental impacts associated with coal mining activities in Makarwal area Pakistan. To achieve objectives, 41 soil samples were collected from coalmine-affected areas analyzed for major toxic trace elements (TTEs) using atomic absorption spectroscopy. Most of have extremely high concentrations metals such as Ni, Cd, Cr, Cu, Zn, ...

This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located Carpathian Mountains – Pannonian Basin south Danube River (Serbia). The main objective was to determine contamination by ten potentially toxic elements (As, B, Cd, Cr, Cu, Mn, Mo, Ni, Pb, Zn) and evaluate associated ecological risk via different indices. physicochemical parameters, pH, or...
