The Himalayas - SLCPs in High Elevation Regions 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 rate of warming over the Himalayan-Tibetanplateau, with multiple benefits for public health, food security and disaster risk reduction.

Effects on Public Health - Air Pollution, a Preventable Risk 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 pollution are the fourth and seventh leading risk factors for early mortality globally. In 2010 indoor and ambient outdoor particulate matter pollution were estimated to have caused over 3.5 and 3.2 million premature deaths respe...

What are Short-Lived Climate Pollutants? 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 in SLCP emissions will quickly have a major positive effect on public health, agriculture in addition to the short-term mitigation of climate problems.

Major industrial sectors emitting metals in the Mediterranean region 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 metal industry (Pb, Zn). Water releases appear to be mostly related to the fertiliser industry (Hg, As, Pb), metal industry (Ni, Zn) and wastewater treatment plants (Cd, Cu), with important contributions also from the energy sec...

Compact fluorescent lamps (CLFs) Compact fluorescent lamps (CLFs)
Mercury is widely used in compact fluorescent lamps (CFLs) and the demand for them is increasing in the quest for energy efficiency. According to the EU Directive 2002/95/EC on the restriction of hazardous substances in electrical and electronic equipment (RoHS Directive), mercury content in CFLs not exceeding 5 mg per lamp is allowed. These lamps reduce electricity consumption so that in countries that generate electricity largely from coal, the...

How mercury can enter our environment 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 effective disposal methods – to finish up thousands of kilometers away because of its propensity to travel through air and water. Beyond that, it reaches the environment more often after being unintentionally emitted than through negligen...

Global mercury supply Global mercury supply
Artisanal and small-scale Gold Mining (ASGM) is the largest sector of demand for mercury, using it to separate the metal from the ore. Though mercury mining and by-products were very high in the eighties, since then, mining practices have reduced and recycling is on the rise.

Discharge of selected pollutants Discharge of selected pollutants
Discharge of selected pollutants around Caspian sea. Air quality has generally improved in recent years, mainly because industrial production has dropped drastically since the collapse of the Soviet economic system. But increasing emissions from the expanding oil and gas sector, and a growing number of cars in cities, not only affect the health of local people but contribute to the accumulation of greenhouse gases in the atmosphere, in ...

All data and information were prepared in close collaboration with the GIWA Black Sea team and the GIWA secretariat. The graphics were not used in this form in the final report on the Black Sea, published in 2005.

Mining waste emissions to land and water in Australia Mining waste emissions to land and water in Australia
PRTRs (Pollutant Release and Transfer Registers) are databases of chemical releases to air, land and water from factories or other sources. Targeting a broad public audience, they support our right to information on toxic waste and air pollution. The Australian National Pollutant Inventory (NPI), for instance, not only provides the public with free access to data on its website but also helps facilities estimate and report emissions.

Cell phone composition Cell phone composition
It is impossible to detail all the types of waste directly or indirectly involved in manufacturing mobile phones. In developed countries production processes manage to keep sensitive materials in a closed circuit, without any waste escaping to the outside world. Production – “Made in Elsewhere” – does not usually take place where the phones are most widespread. Degrees of efficiency in health and environmental protection vary. In some assembly ...

When the city harms its own water resources When the city harms its own water resources
In areas where surface water is not readily available (located far from areas of need), groundwater is the primary water source. Groundwater aquifers supply an estimated 20% of the global population living in arid and semi-arid regions. Despite their widespread presence, groundwater aquifers in arid areas receive only limited or seasonal recharge, making such aquifers susceptible to rapid depletion. The Northern Sahara Basin Aquifer, for example,...
