What is in a computer What is in a computer
On average a computer is 23% plastic, 32% ferrous metals, 18% non-ferrous metals (lead, cadmium, antimony, beryllium, chromium and mercury), 12% electronic boards (gold, palladium, silver and platinum) and 15% glass. Only about 50% of the computer can be recycled, the rest is dumped. The toxicity of the waste is mostly due to the lead, mercury and cadmium – non-recyclable components of a single computer may contain almost 2 kilograms of lead. ...

Mercury pollution - transport and cycle Mercury pollution - transport and cycle
Mines use toxic chemicals including cyanide, mercury, and sulphuric acid, to separate metal from ore. The chemicals used in the processing are generally recycled, however residues may remain in the tailings, which in developing countries are often dumped directly into lakes or rivers with devastating consequences. The accidental spillage of processing chemicals can also have a serious impact on the environment. For example, at the Baia Mare mine ...

Discharge of pollutants in the Caspian Sea - mercury and cadmium Discharge of pollutants in the Caspian Sea - mercury and cadmium
Mercury and Cadmium are classified as toxic metals, and are persistant pollutants in the environment, that stays in the system and is accumulated through the food chains. The main release of these pollutants are on the west coast of the Caspian Sea, off the coast of Russia and Azerbaijan.

Toxic metals in sediments of the Caspian Sea (Arsenic, Mercury and Copper) Toxic metals in sediments of the Caspian Sea (Arsenic, Mercury and Copper)
Sampled sediments in the Caspian Sea show that arsenic is spread out at multiple locations, but primarily on the southern and southwest shores of the Sea, on the shores of Iran and Azerbaijan - where also Copper is accumulated in the sediments. Mercury is concentrated on the Apsheron peninsula of Azerbaijan.

Industrial pollution and waste hotspots in the Ferghana Valley Industrial pollution and waste hotspots in the Ferghana Valley
Mercury mining, uranium mining, chemical and textile industries, oil facilities and processing plants which contribute to the contamination of the soil with highly toxic heavy metals are recognized as environmental challenges in the region. Even though past spills and contaminations have caused tensions between the different countries of the region, officials do not consistently regard environmental pollution by existing facilities as a security ...

Mercury levels in indigenous women Mercury levels in indigenous women
Many POPs (persistent organic pollutants) and heavy metals from emissions further south are accumulated in Arctic food chains and ultimately in indigenous peoples. While fear of these compounds sometimes has resulted in abandonment of traditional foods, this has also led to more unhealthy food habits acquired from non-indigenous peoples. Most indigenous peoples in smaller communities still supply a large share of their household foods from natura...
