China presently contributes the largest amount of anthropogenic mercury (Hg) emission into the atmosphere in the world. Over the past decade, numerous studies have been conducted to characterize the concentration and forms of atmospheric Hg in China, which provide insights into the spatial and temporal distributions of atmospheric Hg through ground-based measurements at widely diverse geographical locations and during cruise and flight campaigns. In this paper, we present a comprehensive review of the state of understanding in atmospheric Hg in China.

Corporate climate action is increasingly considered important in driving the transition towards a low-carbon economy. For this, it is critical to ensure translation of global goals to greenhouse-gas (GHG) emissions reduction targets at company level. At the moment, however, there is a lack of clear methods to derive consistent corporate target setting that keeps cumulative corporate GHG emissions within a specific carbon budget (for example, 550–1,300 GtCO2 between 2011 and 2050 for the 2 °C target).

Carbon markets are considered a key policy tool to achieve cost-effective climate mitigation1, 2. Project-based carbon market mechanisms allow private sector entities to earn tradable emissions reduction credits from mitigation projects. The environmental integrity of project-based mechanisms has been subject to controversial debate and extensive research1, 3, 4, 5, 6, 7, 8, 9, in particular for projects abating industrial waste gases with a high global warming potential (GWP).

In this study, we evaluated 10 months data (September 2009 to June 2010) of atmospheric aerosol particle number size distribution at three atmospheric observation stations along the Baltic Sea coast: Vavihill (upwind, Sweden), Utö (upwind, Finland), and Preila (downwind, Lithuania).

While insufficient sanitation facilities often get represented in statistics and are reported in the literature on urban infrastructure planning and contested urban spaces, what is often left out is the everyday practice and experience of going to dysfunctional toilets, particularly by women. By analysing the practices and problems associated with toilet use from a phenomenological perspective, this article aims to situate the issue in the everyday lives of women.

The law and policy frameworks for allocation or reallocation of water to different uses, or within a category of use, remain underdeveloped in India. This paper intends providing a starting point for a conversation on the law and policy dimensions of inter-sectoral water allocation. Focusing on a specific inter-sectoral water allocation conflict in Rajsamand District, Rajasthan, it illustrates gaps in the existing law and policy frameworks and highlights multiple issues that need to be addressed.

Bihar's public distribution system used to be one of the worst in India, but the system has improved significantly from 2011 onwards. The National Food Security Act, backed early on by the political leadership, enabled the state to include the bulk of the rural population in this improved system. However, there is still a long way to go in ensuring that the system is reliable, transparent and corruption-free.

The meeting to draw up a climate change regime for 2020 and beyond in Paris later this year will, as usual, be fraught with overwhelming complexity. Will "climate clubs" be able to offer room for making greater efforts in smaller groups?

Non-thermal microwave/lower frequency electromagnetic fields (EMFs) act via voltage-gated calcium channel (VGCC) activation. Calcium channel blockers block EMF effects and several types of additional evidence confirm this mechanism. Low intensity microwave EMFs have been proposed to produce neuropsychiatric effects, sometimes called microwave syndrome, and the focus of this review is whether these are indeed well documented and consistent with the known mechanism(s) of action of such EMFs.

Road dusts contribute a large fraction of air pollution in urban environment of India. In the present work, contamination assessment of ions and elements i.e. F−, Cl−, NO3 − , 2 SO4 − , NH4 + , Na+, K+, Mg2+, Ca2+, As, Cr, Mn, Fe, Ni, Cu, Zn, Pb and Hg in the road dusts of the most industrialized area of central India: Raipur (capital, Chhattisgarh state) is described during year: 2008-2013.
