      Air Pollution
      The authors explored whether birth weight at term is affected by PM2.5, PM10 (PM ≤ 10 µm), and gaseous pollutants. Several PM2.5 chemical components were associated with LBW. Risk increased 4.9% (95% CI: 3.4, 6.5%), 4.7% (3.2, 6.2%), 5.7%  (2.7, 8.8%), and 5.0% (3.1, 7.0%) per interquartile range increase of PM2.5 aluminum, elemental carbon, nickel, and titanium, respectively. Other PM2.5 chemical components and gaseous pollutants showed associations, but were not statistically significant in multipollutant models. The trimester associated with the highest relative risk differed among pollutants. Effect estimates for PM2.5 elemental carbon and nickel were higher for infants of white mothers than for those of African-American mothers, and for males than females. The authors noted that most exposure levels in their study area were in compliance with U.S. Environmental Protection Agency air pollution standards; however, they identified associations between PM2.5 components and LBW. Findings suggest that some PM2.5 components may be more harmful than others, and that some groups may be particularly susceptible.

      The authors prospectively evaluated the associations of maternal air pollution exposure with markers of placental growth and function among 7,801 pregnant women in the Netherlands. Higher PM10 and NO2 exposure levels were associated with lower second-trimester maternal soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF) levels. PM10 and NO2 exposures averaged over total pregnancy were associated with higher sFlt-1 and lower PlGF levels in fetal cord blood, consistent with an anti-angiogenic state. PM10 and NO2 exposures were not consistently associated with second- or third-trimester placental resistance indices. NO2 exposure was associated with third-trimester notching (odds ratio 1.33; 95% CI: 0.99, 1.78 per 10-μg/m3 increase in the prior 2 months). PM10 and NO2 exposures were associated with lower placenta weight (–11.8 g; 95% CI: –20.9, –2.7, and –10.7 g; 95% CI: –19.0, –2.4, respectively, per 10‑μg/m3 increase in the prior 2 months), but not with placenta to birth weight ratio. The results suggest that maternal air pollution exposure may influence markers of placental growth and function.

      Chemicals
      There is increasing interest in the potential effects of polybrominated diphenyl ethers (PBDEs) on children’s neuropsychological development, but only a few small studies have evaluated such effects.
      The authors examined the association between PBDE concentrations in colostrum and infant neuropsychological development and assessed the influence of other persistent organic pollutants (POPs) on such association. Increasing Σ7PBDEs concentrations showed an association of borderline statistical significance with decreasing mental development scores. BDE-209, the congener present in highest concentrations, appeared to be the main congener responsible for this association. There was little evidence for an association with psychomotor development. After adjustment for other POPs, the BDE-209 association with mental development score became slightly weaker. The findings suggest an association between increasing PBDE concentrations in colostrum and a worse infant mental development, particularly for BDE-209, but require confirmation in larger studies.

      Children and adults are still routinely exposed to very high levels of lead in developing countries, particularly in regions with a long mining history, such as the Andes. This study focuses on Peru, which ranks among the world’s top five producers of silver, zinc, lead and copper and has a long and conflict-ridden mining history. The objective of this study was to estimate the population of Peru living in the vicinity of active or former mining operations that could be exposed to lead from contaminated soil. Spatial analysis indicated that 1.6 million people could be living within 5 km of an active or former mining operation. The authors concluded that soil contamination with lead is likely to be extensive in Peruvian mining towns but the level of contamination is spatially far from uniform. Childhood exposure by soil ingestion could be substantially reduced by mapping soil lead levels, making this information public and encouraging local communities to isolate contaminated areas from children.

      Pesticide volatilization and vapor drift can have adverse effects on non-target, sensitive ecosystems and human health. Four approaches for pesticide volatilization screening based on Fick’s Law were investigated. In each approach, vapor pressures or environmentally relevant partition coefficients were used to describe pesticide behavior in an agricultural field system and to predict 24-h cumulative percentage volatilization losses. The multiphase partitioning approach based on soil-air  and water-air  partition coefficients was found to most accurately model literature-reported pesticide volatilization losses from soils.

      Although Integrated Environmental Health Monitoring (IEHM) is considered an essential tool to better understand complex environmental health issues, there is no consensus on how to develop such a programme. The authors reviewed four existing frameworks and eight monitoring programmes in the area of environmental health. We identified the DPSEEA (Driving Force-Pressure-State-Exposure-Effect-Action) framework as most suitable for developing an IEHM programme for environmental health impact assessment. Our review showed that most of the existing monitoring programmes have been designed for specific purposes, resulting in narrow scope and limited number of parameters. This therefore limits their relevance for studying complex environmental health topics. They proposed a DPSEEA-based conceptual framework for an IEHM programme that would enable monitoring and measuring the impact of environmental changes on human health.

      Acrylamide is a common dietary exposure that crosses the human placenta. It is classified as a probable human carcinogen, and developmental toxicity has been observed in rodents. The authors examined the associations between prenatal exposure to acrylamide and birth outcomes in a prospective European mother–child study. Both acrylamide and glycidamide Hb adducts were associated with a statistically significant reduction in birth weight and head circumference. Findings were similar in infants of nonsmokers, were consistent across countries, and remained after adjustment for factors associated with reduced birth weight. Maternal consumption of foods rich in acrylamide, such as fried potatoes, was associated with cord blood acrylamide adduct levels and with reduced birth weight. The authors concluded that dietary exposure to acrylamide was associated with reduced birth weight and head circumference. Consumption of specific foods during pregnancy was associated with higher acrylamide exposure in utero. The authors concluded that confirmation of  these findings would suggest that dietary intake of acrylamide should be reduced among pregnant women.

      After a rapid expansion of malaria prevention and control programmes between 2004 and 2009, global funding to fight malaria levelled off between 2010 and 2012. According to the World malaria report 2012, a funding slowdown could reverse recent gains in the fight against one of the world’s leading infectious killers. WHO (17/12/12)

      The UNICEF progress report says early funding by donors meant crucial supplies of ready-to-use therapeutic food were purchased in good time and pre-positioned. However, there were significant challenges in the year due to people being displaced into neighbouring countries because of conflict in Mali, insecurity and severe flooding.  UNICEF (11/12/12)
       
      Countries have successfully launched a new commitment period under the Kyoto Protocol, agreed a firm timetable to adopt a universal climate agreement by 2015 and agreed a path to raise necessary ambition to respond to climate change. UNEP (9/12/12)

      While vulnerability to climate change poses risks to all communities, the impacts are likely to be tilted against many of the world’s poorest regions, which have the least economic, institutional and technical ability to adapt and cope. “Seeds of Knowledge” aims to show that grassroots, community-led responses are already playing an essential role in building resilience to climate change across all regions of the world.

      High blood pressure has become the world's deadliest disease-causing risk factor. But for Indians, indoor air pollution – from chulhas burning wood, coal and animal dung as fuel – has been found to be a bigger health hazard, claiming 500,000 lives in India every year, according to the WHO. Times of India (14/12/12)
