Problem Statement Industries are generated waste water, which contain dyes and pigments in waste water. Characteristically high in colour and organic content (Grag, et al., 2004). Dyes are widely used in industries such as textile, rubber, paper, plastic, and cosmetic. There are many of dyes exist in industries and one of them is methyl red and through nano zerovalent iron removal of dyes from waste water. Dye industry effluents constitute one of the most problematic wastewaters to be treated…

This may cause accumulation of errors rapidly in the cell and its progeny. * Those in signaling (endocrine) machinery of the cell. This leads transmission of the error signals to nearby healthy cells as well. * Those that allow the cells to migrate and disrupt more healthy cells away from the primary site of origin. * Those that make the cell immortal so that the abnormal cell refuses to die. Hormonal changes Notable among these are changes in the female hormone levels estrogen. Excess…

The data from epidemiological, animal and in vitro studies indicated the nature of interaction between PAHs and metals varies from synergism to additivity or antagonism. In this chapter, the combined toxicity of PAHs and metals on toxicokinetic and toxicodynamic endpoints, and possible mechanism of actions were discussed. In addition,…
