Assessment of Bioaugmentation and Biostimulation Efficiencies for Petroleum Contaminated Sediments
The effectiveness of hydrocarbon bioremediation strategies approaches is depending on various issues such as type and volume of pollution, nutrient accessibility in the target ecosystem, time, biodiversity of microorganisms, pollutant bioavailability and many others. In the present research, laboratory studies were carried out on the bioremediation of coastal sediment samples ...
متن کاملEvaluation of alternative approaches for screening contaminated sediments and soils for polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans.
Traditional high resolution mass spectrometry (HRMS) analysis for polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) can be time consuming and expensive. Consequently, alternative methods are of great interest to regulatory agencies and others characterizing contaminated sites. One factor that hinders acceptance of alternative methods is a lack of performance informat...
متن کاملEnvironmental toxicology of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans.
Few environmental compounds have generated as much interest and controversy within the scientific community and in the lay public as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Their ubiquitous presence in the environment and the risk of accidental exposure has raised concern over a possible threat of PCDDs or PCDFs to human health. The most extensively ...
متن کاملCharacterization of polychlorinated dibenzo-p-dioxins and dibenzofurans in different particle size fractions of marine sediments.
The distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was examined according to particle size in marine sediments, with a particular focus on fine particulates. Samples from different coastal sites were fractionated into five size groups (<2, 2-5, 5-10, 10-20, and 20-63 microm diameter) by gravitational split-flow thin fractionation. Despite the different size profil...
متن کاملSources and distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans in sediments from Masan Bay, Korea.
Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/DFs) were measured in sediments collected from Masan Bay, Korea. Almost all tetra- through octachlorinated PCDDs/DFs were identified, including the 17 2,3,7,8-substituted PCDDs/DFs. Total concentrations of PCDDs/DFs in sediments ranged from 102 to 6,493 pg/g dry weight. Concentrations of 2,3,7,8-tetrachlorinated dibenzo-p-dioxin (TeCDD)...
