Pages 50-55
Shabana Siddique, Qiming Xian, Nadia Abdelouahab, Larissa Takser, Susan P. Phillips, Yong-Lai Feng, Bing Wang, Jiping Zhu

• Dechlorane plus levels in human milk were lower than polybrominated diphenylethers.
• Dechlorane plus and polybrominated diphenylethers have different sources.
• Isomer ratios of dechlorane plus were similar to its commercial formulations.

Brominated flame retardants and polychlorinated biphenyls in human breast milk from several locations in India: Potential contaminant sources in a municipal dumping site

Pages 87-95
Gnanasekaran Devanathan, Annamalai Subramanian, Agus Sudaryanto, Shin Takahashi, Tomohiko Isobe, Shinsuke Tanabe

• Contamination status of organohalogen compounds in human milk samples from India was investigated.
• Significantly high levels in municipal dumping site indicate that the open dumping sites could act as potential sources.
• Different organohalogen profiles between dumping site and general population suggest region-specific sources and pathways.
• Hazard Quotient values for PCBs exceeded one, indicating that infants/mothers living around dumping site are at high risk.
• This is the first comprehensive study on the pollution of BFRs from India.

Tri-decabrominated diphenyl ethers and hexabromocyclododecane in indoor air and dust from Stockholm microenvironments 2: Indoor sources and human exposure

Pages 141-147
Cynthia A. de Wit, Justina Awasum Björklund, Kaj Thuresson

• Indoor air and dust from Stockholm microenvironments contain tri-decaBDEs and HBCD.
• BFR levels were linked to electronics, foam furniture, mattresses and bed pillows.
• Dust ingestion may be important for toddler's exposure to PentaBDE and HBCD.
• Inhalation of office air is also an important exposure route for PBDEs for adults.

The effect of in utero exposure to dioxins and polychlorinated biphenyls on reproductive development in eight year-old children

Pages 181-187
Pen-Hua Su, Po-Chin Huang, Ching-Yi Lin, Tsung-Ho Ying, Jia-Yuh Chen, Shu-Li Wang

• BA appeared to be unaffected by exposure level, indicating normal growth.
• E2 concentrations were significantly related to PCDD/Fs+PCB exposure level.
• Fundus length correlated with PCBs exposure level in girls.

Analysis of the toxicogenomic effects of exposure to persistent organic pollutants (POPs) in Slovakian girls: Correlations between gene expression and disease risk

Pages 188-199
Partha Sarathi Mitra, Somiranjan Ghosh, Shizhu Zang, Dean Sonneborn, Irva Hertz-Picciotto, Tomas Trnovec, Lubica Palkovicova, Eva Sovcikova, Svetlana Ghimbovschi, Eric P. Hoffman, Sisir K. Dutta

• A structural effect of POP exposure on gene expression was established.
• Common genes of interest to POP exposure were identified.
• The associated network of genes involved in POP exposure was identified.
• The molecular mechanism of toxicity in POP exposure was provided.
• This study will help with the identification of predictive markers in a POP exposure scenario.

Chronic risk assessment of exposure to volatile organic compounds in the atmosphere near the largest Mediterranean industrial site

Pages 200-209
Noelia Ramírez, Anna Cuadras, Enric Rovira, Francesc Borrull, Rosa Maria Marcé

• We have monitored 86 volatile organic compounds (VOCs) near the largest chemical site of South Europe. We have not found non-carcinogenic health effects as results of VOC exposure. We have found a global cancer risk of 3.3 cases per 10,000 people exposed. This result is above the values recommended by the WHO and the USEPA. We have also found some influence of the analytical method in the estimated risk.
