... and sediment texture) were also assessed. Findings Concentrations of P, Fe and Al in waters exceeded the national standards, but sediments were not considered to be contaminated by metals or nutrients. Water and sediments tended to exhibit marginal toxicities, excluding the sediments from JQT007 and JQT008...

... assessments are required to fully address the risks to resident fauna of anthropogenic contaminants deposited in estuarine sediments. Originality/value The paper presents an updated discussion of the methodologies for environmental assessments of contaminated estuarine sediments. © Emerald Group...

... A questionnaire was designed and developed as a descriptive survey of the target population's perceptions of the impact of chemical contaminants on health. Statistical data analysis was conducted to determine the response difference among variables. Findings The survey demonstrated higher perceptions...

... of German governmental research institutions have been integrated in the paper. Findings In Brazil, despite the lack of a federal public policy, the State of São Paulo has approved specific rules to deal with contaminated sites. Topics that could be targets of scientific studies have been identified...

..., this factor is seasonal, and is particularly dependent on rainfall (see Figure 1). The conductivity parameter is important for indicating contamination by inorganic substances or tidal effects. It is crucial in determining water quality, since organisms are affected when conductivity levels are much...

Hassan; Ramzi Taha; Abdulwahid Hago; Bader Al‐Shandoudi; Yahia Al‐Suleimani Purpose To investigate the effect of cement and cement by‐pass dust (CBPD) as a stabilizer on the geotechnical properties of oil‐contaminated soils resulting from leaking underground storage tanks...

...S.A. Mashi; S.A. Yaro; P.N. Eyong Purpose Contamination of the environment by heavy metals is a phenomenon of global importance today. When present in high concentrations in the environment, heavy metals may enter the food chain from soils and result in health hazards. Accumulation in street dust...

...G. Pepin; H. Baroudi; M. Nomine Supporting many policies of contaminated sites management, the risk assessment methodology needs a deep knowledge of the characteristics of the contamination of soils. Physico‐chemical analysis has to take in account the heterogeneity and the specificity of the soil...

... are exposed to both copper and lead pollution as a consequence of the inhalation and ingestion of heavy metals, which often involves significant bio‐accumulation through trophic levels. This paper explores aspects of an important source of severe dietary contamination which has potential public health...

...Lars Meierling; Werner Hegemann The aerobic microbial treatment of a groundwater contaminated with several organic compounds was investigated. This microbial process was combined with posttreatment by activated carbon. Mixed cultures were immobilised on polyurethane foam carrier material...

...Ross Prizzia This paper describes the concept of natural attenuation and its role as a remediation method. It contains examples illustrating the various modalities via which natural attenuation may assist in dealing with environmental contamination. The scientific literature describes natural...

... of this area. In order to achieve organized land occupation and self‐sustained development, thematic maps of the physical environment were elaborated. Analysis of the water sources supply and recreation have been completed. The risk of water contamination has increased, caused by the increase of tourism...

.../Air clinic” was investigated. The ability of particles to remain airborne or pass through filters depends on the size and density of particles. Air clinic device removed bacterial and mould contaminants in efficiencies up to 98.7 per cent and 67 per cent respectively, after 30 minutes of operation...

... medium contaminating it and affecting consumers’ health. This work concerns the study of migration of DINP and DOP plasticisers from PVC sheets into foodstuffs. PVC sheets using either type of plasticisers with different concentrations were prepared and then put in contact with different food simulants...

...J.J.W. Mol Petrochemical and refining operations can cause severe environmental damage due to emmisions to soil, air and ground‐ and surface water. The general framework for remedial actions is primarily determined by the legal framework and the actual risks associated with levels of contaminants...

... are for a federally protected wildlife. The electrokinetic process will be used to mobilize and extract heavy metals from the metals‐contaminated soil by applying a low amperage direct current across an array of electrodes placed in the contaminated soil. The demonstration will focus on the effectiveness of the EK...

...S.M.E. Meehan; T.R. Weaver; C.R. Lawrence Cyanide is extremely toxic to both human and aquatic life and exists as a contaminant in soils and groundwater at decommissioned gasworks sites due to past industrial practices. This included the processing and disposal of gas purification wastes which...
