Russia cadmium

In 1988, cadmium metal production in the United States increased significantly and imports decreased, but exports increased. Dramatic increases in cadmium prices in 1988 were attributed to the tight supply of cadmium worldwide, heavy speculative trading, and the large quantities of cadmium being purchased by the nickel—cadmium battery industry, particularly in Japan. About 30 countries are cadmium producers, led by Russia, Japan, the United States, Canada, Belgium, Germany, and Mexico, which cumulatively represented 64% of the 1988 reported world cadmium production of 19,773 metric tons.

For each sea the contribution of various emission sources to atmospheric depositions was assessed. It is obvious that the countries with high emissions, located close to the seas, make the highest contributions to anthropogenic depositions. For example, the most significant contribution to the North Sea comes from the United Kingdom (28%) and Germany (16%). The main anthropogenic contributor to the Caspian Sea is Russia (46%), followed by Azerbaijan (22%) and Turkey (12%). Similar information is also available for cadmium and mercury.

Manufacture of iron-nickel oxide batteries commenced in 1908, but the system did not have the commercial success of nickel-cadmium. Until comparatively recently, there was only a very limited production of stationary batteries in the USA, Germany and Russia. Developments of improved iron electrodes have altered the situation, and the iron-nickel oxide system is now being actively considered for EV propulsion and other applications. 

As of2008, China, Korea, Canada, Kazakhstan, Japan, Mexico, Russia, and the United States were among the largest producers of cadmium. 

The data on annual wood biomass production in the main forest types have been taken from (Bazilevich, 1993). We used the value of maximum permissible level of lead in the wood equal to 0.(X)5 g/kg as an accepted in Russia (Moiseev, 1994). To estimate cadmium accumulation in the biomass, the background values equal to 0.25 mg/kg for coniferous species, 0.5 mg/kg for small leaf species and 0.6 mg/kg for broad leaf species (Uchvatov, 1995), were used. The metal accumulation in the wood biomass was not calculated for the areas without forest ecosystems, for example, tundra and steppe ecosystems. We supposed that metal conservation in the biomass of these natural ecosystems was only temporal with subsequent mineralization of organic matter and entering biogeochemical cycling. 

Environmental friendliness is of course only one important aspect to be considered. Explosives that show extraordinary properties such as stability, sensitivity, initiation efficiency, compatibility, or other properties can find their application in some special cases even though they will not meet the green criteria. Typical examples of such explosives may be the mercury salt of tetrazole or cirkon (cadmium(ll)tris-carbonohydrazide) perchlorate used in Russia [12, 13]. 

Cadmoselite is a black hexagonal mineral named after its chemical composition, CdSe. Its type locality is Tuva, Siberia, Russia and was discovered by Bur yanovae/o/. in 1957. It is a rare mineral but its synthetic counterpart, cadmium selenide, which forms a red or grey to brown powder, is known in a pigment context, principally in conjunction with cadmium sulfide to form orange to red cadmium selenide sulfides (. v.).
