This study summarizes the chemical effects that can occur during corrosion process of carbon steel in a CO2-saturated aqueous environment. Particularly, it focuses more on results small contaminations environment have process. Underground waters present complex chemistry with several different dissolved ions (chlorides, carbonates) even high concentrations impact substantially rates these mater...

Brominated flame retardants (BFRs) including polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) were determined in Baikal seals (Pusa sibirica) collected from Lake Baikal to reveal their contamination status, accumulation features and temporal trends. Organohalogen compounds analyzed were detected in all the blubber samples of Baikal seals. DDTs were the most abundant co...

Data from recent sediment and surface water surveys have been collated and mapped to illustrate the spatial distribution of contaminants across the entire Great Lakes basin. Information from historical surveys, together with data from surface water monitoring programs in three major connecting channels, has also been collated in order to evaluate temporal trends. In general, Lakes Superior and ...

The most significant impact of a landfill on the surrounding environment has been consistently identified as arising from the leachate (Farquhar 1989; CAE 1992; Mulvey 1997). Therefore, environmental monitoring programmes for landfills tend to focus on the detection of leachate impacts, particularly any contamination of ground and surface water (Lee and Jones 1991; DCC 1994). Conventional monit...

Libreville, the largest city in Gabon, adversely impacts Komo Estuary and Akanda National Park aquatic ecosystems through discharge of domestic industrial waste. Fecal Indicator Bacteria (FIB: Escherichia coli fecal streptococci) were enumerated using culture-based methods water from 40 sites between 2017 2019 including coastal outlets, mangrove channels, open bays littoral rivers. Contaminatio...

Alluvial soils can store a wide range of metal contaminants originating from point and diffuse sources. The biological health of these soils is important as they act as an interface between terrestrial and aquatic environments, therefore playing an important role in maintaining the quality of surface waters. The aim of this work was to examine the lability, solubility and bioavailability of Pb,...

Contamination by hazardous substances is one of the main environmental problems in eastern Gulf Finland, Baltic Sea. A trilateral effort to sample and analyse heavy metals (HMs), polycyclic aromatic hydrocarbons (PAHs), organotins from bottom sediments 2019–2020 were conducted along with harvesting historical data Russian, Estonian Finnish waters. We suggest that input still occurs ship traffic...

Lubumbashi (DR Congo)—the capital of copper mining—has been considered as one the richest mining regions world for more than a decade. These riches have brought along multiple companies responsible soil, river water and vegetable pollution, in many African cities. The aim present study was to quantify evaluate pollution levels potential sources irrigation contamination by metals As, Cd, Cr, Cu,...

In this research we assessed the concentration of total mercury in the muscle, liver and gill tissues of Indian spiny turbot, Psettodes erumei caught from Jask coastal waters in Hormozgan province. Fifteen fish specimen were caught using trawl in spring season 2008. After biometrical measurements and sex determination, muscle, liver and gill tissues were collected mercury was extracted from the...
