An Environmental Risk Assessment Model for the Chemical Synthestic Pharmaceutical Wastewater by Euglena

Article Preview

Abstract:

Trying to carry out environmental risk assessment for the chemical synthestic pharmaceutical wastewater quantificational, the investigation for the fauna of aquatic protozoa, co-relationship analysis among different concentrations of wastewater and survival rates of primarily selected protozoa, and fitting function analysis were performed. At last the euglena, the representative bio-indicator, was selected according to the principles of being dominant species, high co-relationship and high coefficient of fitting function. The optimal culture time was set as 60 mins empirically, that at this point the survival rates of euglena were influenced by the concentrations of wastewater mainly with the biggest difference spectrum of 0.183 and highly significant negative co-relationship (r=-0.9988, P=0.022). The equation of fitting function was: y=-0.69x+0.82; the risk levels were set according to the fitting function: survival rate≥0.82, no risk; 0.41
