The discharge of organic pollutants into lakes or declines in the concentrations of copper, zinc, and other heavy metal toxins may promote the growth of phytoplankton (e.g. algal blooms ). Greater biological activity may then increase anoxic conditions in lake bottoms, which stimulate the reductive dissolution of (oxy)(hydr)oxides and increase the mobilization of arsenic. In particular, Martin and Pedersen (2002) concluded that reduced discharges of copper, zinc, and nickel to Balmer Lake, Ontario, Canada, increased phytoplankton production and arsenic mobility in the lake. 

Cobalt Arsenates.—The ortho-arsenate, Co3(As04)2.8IT20, occurs in nature as erythrite or cobalt bloom in the form of monoclinic crystals isomorphous with vivianite, Fes(P04)2.8lI20, and perhaps with nickel ochre, Ni3(As04)z.8H20. Its crystallographic elements are ...

Among the numerous commercial light stabilizers only a few are suitable for low density polyethylene (LDPE). This is mainly due to the fact that most light stabilizers are not sufficiently compatible at levels of concentration necessary for the required protection and so they bloom more or less rapidly. Initially, UV absorbers of the benzophenone and benzotriazole types were used to protect LDPE materials. With the development of nickel-quenchers, significant improvement in the light stability of LDPE films has been achieved. For reasons of economy, however, combinations of nickel-quenchers with UV absorbers are mainly used. The service life of LDPE films may be increased by raising the concentrations of light...

Steels for WWER-type RPVs are of low-alloyed type, mostly with bainitic microstructure, and thus their radiation damage nature is, in principle, identical with all other RPV steels, with matrix damage, formation of copper-rich precipitates and solute segregation in grain boundaries. Additionally, in materials with a high nickel content, the existence of a late blooming phase is not excluded.

Smaltite, also known as skutterudite or tin white cobalt, is a cobalt arsenate mineral with composition (Co,Ni)As3 , in which the cobalt content exceeds that of nickel iron is a common impurity. It occurs as metallic silver-white cubes or with massive form, often with pink surfaces caused by oxidation (cobalt bloom) to erythrite q.v.). Smaltite is named after its discovery at Skutterud (Norway) and its use in the production of smalt q.v.). If forms in hydrothermal veins associated with cobalt deposits in areas such as Cobalt (Ontario, Canada), Freiberg (Germany), Andalusia (Spain) and Cornwall (England).
