Levels and distribution of organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs) in topsoils from SE Romania

Pages 76-86
Antoaneta Ene, Oleg Bogdevich, Alina Sion

• GC–ECD and GC–MS were used for OCP and PAH determination in soils from SE Romania.
• Emphasis was made on Galati industrial sites and Lower Prut Meadow natural reserve.
• Analyzed OCPs were: HCH isomers, DDT homologs, heptachlor and chlordane.
• Total OCP concentrations were in the range 6–12,644ng/g dry weight.
• Total PAH content (9–25,352ng/g dry weight) is lower in depth that at surface.

• PAH levels of vegetables from e-waste recycling site were quantified.
• High molecular weight PAHs were enriched in plants relative to soils.
• Soil and plant profiles indicated that uptake of PAHs by plants were selectable.
• High level of PAHs in vegetable may pose a potential risk to the consumers

Use of time-of-flight mass spectrometry for large screening of organic pollutants in surface waters and soils from a rice production area in Colombia

• TOF MS hyphenated to LC and GC allows large screening of many organic pollutants.
• Surface waters and soils from a Colombian agricultural area were analyzed by TOF MS.
• Several pesticides and metabolites were detected and unequivocally identified.
• Accurate-mass full-spectrum data allowed the detection of emerging contaminants.

Assessment of legacy and emerging persistent organic pollutants in Weddell seal tissue (Leptonychotes weddellii) near McMurdo Sound, Antarctica

• PBDE measuring in Weddell seal blubber.
• DDE/DDT ratios continue to increase over the past 25years in Weddell seal tissue.
• Weddell seal PBDE burden may be a function of local and/or long-range transport.

Temporal trends of polychlorinated biphenyls and organochlorine pesticides in Great Lakes fish, 1999–2009

Pages 284-290
Fengchih Chang, James J. Pagano, Bernard S. Crimmins, Michael S. Milligan, Xiaoyan Xia, Philip K. Hopke, Thomas M. Holsen

• PBT concentrations in lake trout decreased significantly in Lakes Huron, Ontario, and Michigan between 1999 and 2009.
• Among the PBTs measured PCBs had the smallest decreasing rates, about one half to one third of those for the other PBTs.
• For Lakes Huron, Ontario, and Michigan the lowest detectable annual concentration changes were 5–10% at 80% power.
