A. Demond, A. Franzblau, D. Garabrant, X. Jiang, P. Adriaens, Q. Chen, B. Gillespie, W. Hao, B. Hong, O. Jolliet, and J. Lepkowski
pp 1296–1302

• This article reviews scientific field studies that examine the relationship between living on soil contaminated with dioxins and the level of dioxins in people’s serum, with an emphasis on the University of Michigan Dioxin Exposure Study (UMDES), the largest and most comprehensive study of its kind.

Influence of Organic Matter Content and Human Activities on the Occurrence of Organic Pollutants in Antarctic Soils, Lichens, Grass, and Mosses
Ana Cabrerizo, Jordi Dachs, Damià Barceló, and Kevin C. Jones
pp 1396–1405

• Banned pesticides such as HCB and p,p′-DDE, and other legacy and ongoing pollutants such as PCBs and PAHs, were measured in different vegetation types and soil samples collected at selected areas from Antarctic Peninsula (Deception and Livingstone Islands, Southern Shetlands).

Modern and Fossil Contributions to Polycyclic Aromatic Hydrocarbons in PM2.5 from North Birmingham, Alabama in the Southeastern U.S.
Li Xu, Mei Zheng, Xiang Ding, Eric S. Edgerton, and Christopher M. Reddy
pp 1422–1429

• In this study, we advanced the radiocarbon analysis from bulk carbon to compound class specific radiocarbon analysis (CCSRA) to determine Δ¹⁴C and δ¹³C values of PAHs in PM_2.5 samples for investigating biomass burning and fossil fuel source contributions to PAHs from one of the Southeastern Aerosol Research and Characterization (SEARCH) sites in North Birmingham (BHM), Alabama during winter (December 2004-February 2005) and summer (June-August 2005) by accelerator mass spectrometry.

Organochlorine Insecticides Lindane and Dieldrin and Their Binary Mixture Disturb Calcium Homeostasis in Dopaminergic PC12 Cells
Harm J. Heusinkveld and Remco H. S. Westerink
pp 1842–1848

• Current hypotheses link long-term environmental exposure of humans to persistent organochlorine (OC) insecticides lindane (HCH) and dieldrin (HEOD) to the development of neurodegenerative disorders, such as Parkinson’s disease. In this paper we describe the effect of dieldrin and a binary mixture of dieldrin and lindane on a critical parameter of neuronal function and survival, i.e., intracellular calcium homeostasis.
