摘要:... Various methods for calculating metal enrichment and contamination factors are reviewed in detail and a modified and more robust version of the procedure for calculating the degree of contamination is proposed. The revised procedure allows the incorporation of a flexible ...

摘要:Abstract(#br)An equation which gives the degree of contamination in magmas evolving by assimilation-fractional crystallization is derived.(#br)In an assimilation-fractional crystallization process which proceeds with constant r and D (De Paolo, 1981), if a trace element in the pa...

摘要:Abstract(#br)The concentrations of seven trace metals (Fe, Mn, Cu, Cr, Co, Pb and Zn) in three sediment cores were analysed to assess the depositional trends of metals and their contamination level in the Mandovi estuary, west coast of India. All sediment cores showed enrichm...

摘要:... the accumulation and associated risk of metal contamination would also be expected to change from upstream to downstream reaches. Speciation and degrees of contamination of metals in sediments from the upstream and downstream of river catchments of the southern Bohai Sea were...

摘要:... Molecular analysis was used to assess cell contamination by employing specific probes, namely transition protein 2 (TP2), mitochondrial cytochrome C oxidase II (COX II), and sulfated glycoprotein 1 (SGP1). Molecular analysis of the samples demonstrated that morphological...

摘要:Abstract(#br)The objective of the study is to reveal the seasonal variations in the river water and sediment quality with respect to heavy metal contamination. To get the extent of trace metals contamination, water and sediment samples were collected from five different sites alo...

摘要:... In addition to the parameters of the Gaussian CWM, each mixture component has a parameter controlling the proportion of outliers, one controlling the proportion of leverage points, one specifying the degree of contamination with respect to the response variables, and anoth...

摘要:... The aim was to establish a baseline for Campylobacter contamination of carcasses against which future interventions could be assessed. However, in the United Kingdom researchers wanted to explore whether different ratios of neck to breast skin in samples could affect the resu...
