      LEAD POISONING IS ENTIRELY PREVENTABLE
       
      Lead poisoning is entirely preventable, yet lead exposure is estimated to account for 0.6% of the global burden of disease, with the highest burden in developing regions. Childhood lead exposure is estimated to contribute to about 600,000 new cases of children with intellectual disabilities every year. Even though there is wide recognition of this problem and many countries have taken action, exposure to lead, particularly in childhood, remains of key concern to health care providers and public health officials worldwide. (Taken directly from WHO website)
       
      The Global Alliance to Eliminate Lead Paint is a cooperative initiative jointly led by the World Health Organization and the United Nations Environment Programme to focus and catalyze the efforts to achieve international goals to prevent children’s exposure to lead from paints containing lead and to minimize occupational exposures to lead paint.

      JOURNAL ARTICLES
       
      Air Pollution
      The authors investigated whether low-level exposure to air pollution is associated with gestational diabetes and preeclampsia. The results showed that the prevalence of gestational diabetes increased with each nitrogen oxides (NOx) quartile, with an adjusted odds ratio (OR) of 1.69 (95% CI: 1.41, 2.03) for the highest (> 22.7 µg/ m3) compared with the lowest quartile (2.5–8.9 µg/m3) of exposure during the second trimester. The adjusted OR for acquiring preeclampsia after exposure during the third trimester was 1.51 (1.32, 1.73) in the highest quartile of NOx compared with the lowest. Both outcomes were associated with high traffic density, but ORs were significant for gestational diabetes only. They concluded that NOx exposure during pregnancy was associated with gestational diabetes and preeclampsia in an area with air pollution levels below current air quality guidelines

      Chemicals
      Bisphenol A (BPA), a widely used endocrine-disrupting chemical, has been associated with increased body weight and fat deposition in rodents. The authors examined whether prenatal and postnatal urinary BPA concentrations were associated with body mass index (BMI), waist circumference, percent body fat, and obesity in 9-year-old children (n = 311) in the CHAMACOS longitudinal cohort study.  Consistent with other cross-sectional studies, higher urinary BPA concentrations at 9 years of age were associated with increased adiposity at 9 years. However, increasing BPA concentrations in mothers during pregnancy were associated with decreased BMI, body fat, and overweight/obesity among their daughters at 9 years of age.
      Environmental Health Perspectives
       
      The authors conducted an environmental epidemiology study of BPA exposure and CpG methylation in pre-adolescent girls from Gharbiah, Egypt hypothesizing that methylation profiles exhibit exposure-dependent trends. They found that CpG methylation varied widely among girls, and higher urinary BPA concentrations were generally associated with less genomic methylation. Based on pathway analyses, genes exhibiting reduced methylation with increasing urinary BPA were involved in immune function, transport activity, metabolism, and caspase activity. In particular, hypomethylation of CpG targets on chromosome X was associated with higher urinary BPA. Using the Comparative Toxicogenomics Database, the authors identified a number of candidate genes in the  sample that previously have been associated with BPA-related expression change. They concluded that the data indicated that BPA may affect human health through specific epigenomic modification of genes in relevant pathways. Thus, epigenetic epidemiology holds promise for the identification of biomarkers from previous exposures and the development of epigenetic-based diagnostic strategies.

      Global Change
      Background: Although many studies have shown that high temperatures are associated with an increased risk of mortality and morbidity, there has been little research on managing the process of planned adaptation to alleviate the health effects of heat events and climate change. The authors examined how public health organizations should implement adaptation strategies and, second, how to improve the evidence base required to make an economic case for policies that will protect the public’s health from heat events and climate change.

      Water and Sanitation
      The authors collected a time series of virus samples from six deep municipal water-supply wells. Three of these wells draw water from beneath a regional aquitard, and three draw water from both above and below the aquitard. The authors also sampled a local lake and untreated sewage as potential virus sources. Viruses were detected up to 61 percent of the time in each well sampled, and many groundwater samples were positive for virus infectivity. Lake samples contained viruses over 75 percent of the time. Virus concentrations and serotypes observed varied markedly with time in all samples. Sewage samples were all extremely high in virus concentration. Virus serotypes detected in sewage and groundwater were temporally correlated, suggesting very rapid virus transport, on the order of weeks, from the source(s) to wells. Adenovirus and enterovirus levels in the wells were associated with precipitation events. The most likely source of the viruses in the wells was leakage of untreated sewage from sanitary sewer pipes.

      E Waste: Solving the e-waste problem (StEP) 
       
      In her recently published StEP Green Paper titled “Transboundary Movements of Discarded Electrical and Electronic Equipment”, Djahane Salehabadi sheds important light on the nature of transboundary e-waste flows and highlights key considerations and challenges related to national and international e-waste policy.
       
      A huge percentage of the world’s electrical and electronic equipment begins its life in China. What is less widely known is that China is also the end-of-life destination for much of the world’s waste electrical and electronic equipment, commonly known as “e-waste”.  As both Chinese and worldwide consumption of electrical and electronic equipment have increased in recent years, so have the environmental and health consequences of its disposal. A new Green Paper titled “E-waste in China: A country report” published by the Solving the E-waste Problem (StEP) Initiative explores and offers key insights into the scale and dynamics of the e-waste problem in China.
       
      A new StEP Green Paper produced by Öko-Institut and PAN-Ethiopia provides a timely overview of the current e-waste situation in Ethiopia and explores possibilities for improving e-waste management in the future.
       
      Note: The StEP Green Paper Series is a publication tool for research findings which meet the core principles of StEP and contribute to its objectives towards solving the e-waste problem. StEP members agreed on this support of the author(s)’ work, but do not necessarily endorse the conclusions made. Hence, StEP Green Papers are not necessarily reflecting a common StEP standpoint.
       
       
      PCBs and PBBs: Polychlorinated biphenyls classified as carcinogenic to humans and polybrominated biphenyls probably carcinogenic to humans.
       
      In February 2013, 26 experts from 12 countries met at the International Agency for Research on Cancer (IARC), Lyon, France, to reassess the carcinogenicity of polychlorinated biphenyls (PCBs) and polybrominated biphenyls (PBBs). These assessments will be published as volume 107 of the IARC Monographs. Link to IARC re recent meeting of experts
      Taken directly from Lancet Oncology:  “On the basis of sufficient evidence of carcinogenicity in humans and experimental animals, the Working Group classified PCBs as carcinogenic to humans (Group 1)”. “On the basis of these similarities with PCBs, and together with inadequate evidence for carcinogenicity in humans and sufficient evidence in experimental animals, PBBs were upgraded to Group 2A, probably carcinogenic to humans”.
