Organic water pollutants from point sources Organic water pollutants from point sources
Organic-matter pollution in industrial wastewater was documented by MED POL through an inventory of industrial point sources of pollution in 2003. The areas with the highest Biochemical Oxygen Demand (BOD) are the southern shore of the Western Basin, the eastern coast of the Adriatic, the Aegean and the northeastern sector of the Levantine Basin. These regions, in general, also have insufficient sewage wastewater treatment facilities. This indic...

Contrast between contemporary and pre-disturbance transports of total nitrogen through inland aquatic systems resulting from anthropogenic acceleration of this nutrient cycle Contrast between contemporary and pre-disturbance transports of total nitrogen through inland aquatic systems resulting from anthropogenic acceleration of this nutrient cycle
While the peculiarities of individual pollutants, rivers, and governance define the specific character of water pollution, the general patterns observed for nitrogen are representative of anthropogenic changes to the transport of waterborne constituents. Elevated contemporary loadings to one part of the system (such as croplands) often reverberate to other parts of the system (to coastal zones, for example), exceeding the capacity of natural syst...

Balkans: hazardous industrial sites, water pollution and mining hot spots Balkans: hazardous industrial sites, water pollution and mining hot spots
The environmental legacy associated with extraction industries is all too familiar. Badly operated or abandoned mining sites have already caused severe pollution, some with impacts spilling across national boundaries: heavy metal spills from Baia Borsa tailings in Romania; the cyanide spill from Baia Mare in Romania; heavy metal spills from Sasa tailings in Macedonia; and various releases at Majdanpek and Veliki Majdan in Serbia, and Mojkovac in ...

Regional trends in biological oxygen demand Regional trends in biological oxygen demand
The graphic is a global comparison of the biological oxygen demand measured in milligrams per litre. It covers the years from 1976 - 2000. The biological oxygen demand refers to the amount of oxygen required by aerobic microorganisms to decompose the organic matter in a sample of water, such as that polluted by sewage.

Iceland, topographic map Iceland, topographic map
Iceland is located in Northern Europe, is an island between the Greenland Sea and the North Atlantic Ocean, northwest of the UK, comprising 103,000 sq km. It has an estimated population of 296,737 (2005). Major environmental concerns are: water pollution from fertilizer runoff; inadequate wastewater treatment.

The Kyrgyz Republic (Kyrgyzstan) is located in Central Asia, west of China, comprising of 198,500 sq km. It has a population of 5,146,281 (2005). Major environmental concerns are: water pollution; many people get their water directly from contaminated streams and wells; as a result, water-borne diseases are prevalent; increasing soil salinity from faulty irrigation practices.

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.

Oil pollution in Azerbaijan Oil pollution in Azerbaijan
There are hundreds of abandoned oil wells in Azerbaijan, and thousands in Kazakhstan, many of which have been submerged by the rising sea. There are reports of big leaks into the water, killing waterfowl and fish. Thousands of hectares of soil on Azerbaijan’s Apsheron peninsula are unsuitable for agricultural use.

Oil spill off the coast of Apsheron peninsula Oil spill off the coast of Apsheron peninsula
Thousands of hectares of soil on Azerbaijan’s Apsheron peninsula are unsuitable for agricultural use due to oil spills. The largest of these oil spills happened in May 1996. Oil extraction is happening off shore, in the Caspian Sea, and the oil is transported by pipelines.

Environment and security issues in Ukraine Environment and security issues in Ukraine
Compared to its neighbours, Ukraine has a very low Environmental Sustainability Index (ESI) (ranking 108 out of 146 countries; Esty et al. 2005). This is primarily due to the high energy and pollution-intensity of its industry, pressure on ecosystems due to intensive agriculture, water stress on part of its territory, and insufficiently developed environmental institutions.

Environment and security issues in Moldova Environment and security issues in Moldova
Since water resources are of particular importance to Moldova, water pollution is viewed as a nationally significant threat. Moldova does not have large lakes, and all its larger rivers originate outside its borders. there are many other issues facing Moldova's environment and security future.

Water competition between cities and agriculture Water competition between cities and agriculture
It is estimated that water pollution denies close to 1.3 billion people (20% of the global population in 2000) access to clean water supplies. In 1986, WHO reported that there were 250 million new cases of waterborne diseases each year, causing the deaths of nearly 3.5 million people. An estimated 4.2 billion cases of waterborne diseases are reported each year, with diarrhoea accounting for 4 billion of the total (Cosgrove and Rijsberman, 2000; R...
