Reports Outline Environmental Contamination and Toxicology Study Findings from Baylor University

June 6, 2014



By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Current study results on Environmental Contamination and Toxicology have been published. According to news reporting originating from Waco, Texas, by VerticalNews correspondents, research stated, "A selective pressurized liquid extraction technique (SPLE) was developed for the analysis of polychlorodibenzo-p-dioxins, polychlorodibenzofurans (PCDD/Fs) and dioxin-like polychlorobiphenyls (dl-PCBs) in clam and crab tissue. The SPLE incorporated multiple cleanup adsorbents (alumina, florisil, silica gel, celite, and carbopack) within the extraction cell."

Our news editors obtained a quote from the research from Baylor University, "Tissue extracts were analyzed by high resolution gas chromatography coupled with electron capture negative ionization mass spectrometry. Mean recovery (n=3) and percent relative standard deviation for PCDD/Fs and dl-PCBs in clam and crabs was 89 2.3 and 85 4.0, respectively. The SPLE method was applied to clams and crabs collected from the San Jacinto River Waste Pits, a Superfund site in Houston, TX. The dl-PCBs concentrations in clams and crabs ranged from 50 to 2,450 and 5 to 800 ng/g ww, respectively."

According to the news editors, the research concluded: "Sample preparation time and solvents were reduced by 92 % and 65 %, respectively, as compared to USEPA method 1613."
