Investigation of the chemical nature and sources of particulate matter at urban locations in four Chinese cities during a severe haze pollution event finds that the event was driven to a large extent by secondary aerosol formation.

Approximately 2.8 billion people cook with solid fuels. Research has focused on the health impacts of indoor exposure to fine particulate pollution. Here, for the 2010 Global Burden of Disease project (GBD 2010), we evaluate the impact of household cooking with solid fuels on regional population-weighted ambient PM2.5 pollution (APM2.5). The researchers estimated the proportion and concentrations of APM2.5 attributable to household cooking with solid fuels (PM2.5-cook) for the years 1990, 2005, and 2010 in 170 countries; and associated ill-health.

Exposure to household air pollution (HAP) from inefficient biomass and coal stoves kills nearly 4 million people every year worldwide. HAP is an environmental risk associated with poverty that affects an estimated 3 billion people mostly in low- and middle-income countries. The objective of the study was to estimate the number of low-income Americans exposed to potentially health-damaging concentrations of HAP.

Epidemiological studies have reported associations between air pollution exposure and increases in cardiovascular morbidity and mortality. Exposure to air pollutants can influence cardiac autonomic tone and reduce heart rate variability, and may increase the risk of cardiac arrhythmias, particularly in susceptible patient groups.

Forests (and landscapes with trees) are such an important part of a number of different Sustainable Development Goals that we recommend working towards a transformative ‘forest module’. The module improves on the more limited current focus on sustainable forest management, deforestation and reforestation targets.

The extent of urban air pollution in Pakistan—South Asia’s most urbanized country—is among the world’s most severe, significantly damaging human health, quality of life, and the economy and environment of Pakistan.

5921–5941One seventh of the world's population lives in the Indo-Gangetic Plain (IGP) and the fertile region sustains agricultural food crop production for much of South Asia, yet it remains one the most under-studied regions of the world in terms of atmospheric composition and chemistry. In particular, the emissions and chemistry of volatile organic compounds (VOCs) that form surface ozone and secondary organic aerosol through photochemical reactions involving nitrogen oxides are not well understood.

Central Electricity Regulatory Commission (CERC) May 15th 2014 order issued revising biomass tariff upwards as well as changing Solar PV, Thermal, Hydro and other tariff substantially by revising capital values for the Financial Year 2014–15.

Thousands of volatile organic compounds (VOCs) in the Earth's atmosphere exist which play an important role in various photochemical processes. However, the global model simulations of tropospheric chemistry deal with limited data of speciated VOCs. In the present study, we have used the Global Fire Emissions Database inventory of VOCs emitted from biomass burning in India during the period from 1997 to 2009.

This document reflects the current state of the art in the growing topic of generating cooking energy by using dry biomass for gasification. It includes the technical background, together with project examples, as well as more recent developments in gasifier stove technologies.
