The Himalayas - SLCPs in High Elevation Regions
SLCPs, especially BC and co-pollutants, are major contributors to the South Asian atmospheric brown cloud, with important consequences for monsoon rainfall and glacier retreat. Fast action on SLCPs could help slow the ra...

Effects on Public Health - Air Pollution, a Preventable Risk
SLCPs, particularly O3 and BC and co-pollutants, which are important parts of PM2.5 air pollution, are harmful to human health. Globally, PM2.5 is a major global cause of premature mortality. Indoor and outdoor PM2.5 air...

What are Short-Lived Climate Pollutants?
SLCPs are substances with a relatively short lifetime in the atmosphere – a few days to a few decades – and a warming effect on near term climate. The main SLCPs are BC, CH4, tropospheric O3, and many HFCs. A reduction i...

Major industrial sectors emitting metals in the Mediterranean region
In the Mediterranean countries, according to the National Baseline Budget (NBB) inventory, atmospheric emissions of metals are mostly related to the cement industry (Hg, Cu), production of energy (As, Cd, Ni) and the m...

How mercury can enter our environment
While some pollutants are restricted in their range and in the size and number of the population they affect, mercury is not one of them. Wherever it is mined, used or discarded, it is liable – in the absence of effectiv...
