Acceleration of emissions reductions in household coal stoves and modest improvements in other sectors, however, have the potential to considerably lower outdoor pollution and reduce total exposures to about 70% of those today (Scenario 1). Reducing total exposures closer to these international benchmark levels will require moving away from coal and wood as household fuels and even more control on other sources (Scenario 2). The first package of moderate control measures (Scenario 1) considered in this assessment will result in a slow decline in impacts(Figure) and a cumulative health savings over trends in 2013, but leave annual per capita health impacts only about 25% lower than today after ten years. A more aggressive set of control measures (Scenario 2), however, will result in more health protection over the period and reduce annual impacts by approximately 60% from current levels in 2025 . In terms of impact per capita,this would represent nearly a 70% reduction over the period taking population growth into account.

Serum and hair zinc in severely malnourished Bangladeshi children associated with or without acute lower respiratory infection.

Objective. To assess the zinc status in Bangladeshi children suffering from severe protein energy malnutrition (severe PEM), acute lower respiratory infection (ALRI), PEM presented with ALRI and to evaluate the relationship of zinc status with aforementioned clinical conditions. Methods. We assessed zinc status by simultaneous estimation of serum and hair zinc of Bangladeshi children less than 5 yr of age suffering from severe PEM, ALRI, severe PEM presented with ALRI and compared them with zinc status of wellnourished healthy children (control) in a hospital based cross sectional four cell study. Zinc concentration was estimated by Flame atomic absorption spectrophotometry. Results. The number of children enrolled in severe PEM, ALRI, ALRI with PEM and control were 47, 35, 32 and 38 respectively (total number 152). Both serum and hair zinc in univariate analysis were found significantly (p<0.05) low in severe PEM, ALRI and severe PEM associated with ALRI. However, in multivariate analysis, when serum and hair zinc were included in the same model, both serum and hair zinc were found to have significant negative association with PEM (p=0.002 & 0.013 respectively) and with ALRI only when ALRI was associated with PEM (p=0.043 and 0.034 respectively). Conclusion. Severe PEM and PEM with ALRI were significantly associated with low zinc status.
