Abstract

Modernization of human society generates numerous chemical from different sources and stimulate serious hazard to the ecosystem. Consequently, people are exposed to thousands of chemicals on daily basis by food, air, water, soil, dust, or the products we use without knowing their harmful effect. It’s not easy for people to identify if those chemicals are risky to their wellbeing or not. These encountered problems require immediate scientific attention to find appropriate and cost effective solutions. Most ecological risk assessments are based on chemical residue analysis of environmental parameters, such as surface water, sediments and soils in addition to determination of species diversity and density of wildlife, though the biological significance of measured chemical concentrations are not so specific and quantitative [1]. Chemical analysis cannot predict actual bio available chemicals, assumed that it is 100% as obtained from analysis of environmental matrix.
