Inorganic Arsenic Pollution

2. Introduction
Rapid industrial development, population explosion and urbanization in developing countries heighten environmental pollution. Environmentalists and greenpeace agencies have increasingly addressed the impact of chemicals to fully recognized as global issue and their increased awareness pushed governors toward more stringent legislation. [1, 2] Of all the natural resource of the world, water is the most abundant covering more than 75% of the earth’s surface. It is recognized as elixir of life and known as general solvent in its pure form. But in the present scenario surface and ground water is terribly polluted by organic and inorganic contaminants. [3]
Some of these pollutants, noticeably heavy metals are potentially hazardous

Living organisms are exposed to the toxic arsenic species primarily from food and water. Drinking water is a major source of inorganic arsenic mainly caused by geochemical reactions, industrial waste discharges, or agricultural use of arsenical herbicides, fungicides and insecticides. There are few and recent findings documenting the occurrence of arsenic above the WHO limit in rural communities in the Rift Valley of Ethiopia where groundwater is the only available drinking water.

Sisal fiber is the most largely quantity widely used, ultrafine fibrous network, highly crystalline structure, derived from matured leaves by crushing and putting them through a process of natural drying, brushing and decortication. It possesses moderately remarkable mechanical strength, stiffness, durability, high purity, low density, ability to stretch, and resistance to deterioration in saltwater which is comparable and may compete with glass fiber in specific strength and modulus. These features made it a candidate as reinforcing material in polymeric resin matrices to make useful structural composite materials. According to research findings based on analysis of chemical composition of sisal fibers, cellulose is most dominant, hemicellulose and lignin contents are comparable while pectin, wax and ash accounts minimal amount.
