Mortality Study of NickelCadmium Battery Workers by the ...

group of nickelcadmium battery workers by the method of regression models in life tables (RMLT). Before the data were first analysed,1 the main hypotheses of interest were listed in order to minim minimise multiple testing and the generation, purely by chance, of some significant results. The hypotheses were arrived at on the basis of other

generation of hydroxyl ions (, the current density) and the steady state conditions of the diffusion processes associated with the precipitation reaction. The diffusion processes involved are nickel or cadmium ions diffusing into the pore structure, H ions diffusing into the pore structure, and OH~ions diffusing into the bulk of the solution from the pores of the electrode. The relative ...

Primary concept of nickel toxicity

Nickel is discharged into the atmosphere either by nickel mining or by various industrial processes, such as power plants or incinerators, rubber and plastic industries, nickelcadmium battery industries and electroplating industries. The extensive use of nickel in various industries or its occupational exposure is definitely a matter of serious impact on human health. Heavy metals like nickel ...
