  2. 1. Application of two dimensional compound specific carbon-chlorine isotope analyses for degradation monitoring and assessment of organic pollutants in contaminated soil and groundwater

    Author : Charline Wiegert; Örjan Gustafsson; Thomas Hofstetter; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organochlorines; chlorinated ethenes; PCE; TCE; hexachlorocyclohexanes; soil contamination; groundwater contamination; remediation; natural attenuation; biodegradation; carbon isotopes; chlorine isotopes; CSIA; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Nearly 250,000 sites with past and present potentially polluting activities need urgent remediation within Europe. Major pollutants include organochlorines (OCls), e.g. chlorinated ethenes (CEs) and hexachlorocyclohexanes (HCHs), mainly used as industrial solvents and pesticides, respectively. READ MORE

    Abstract : Chlorinated organic compounds (OCls) from anthropogenic sources are generally considered to be a class of chemicals with high potential for ecotoxicity, including infamous substances such as polychlorinated biphenyls (PCB), dichloro-dibenzo-trichloroethane (DDT) and polychlorinated dibenzo-p-dioxins (PCDD). OCls are also produced naturally, sometimes at the same order of magnitude as anthropogenic compounds. READ MORE
