Cleaning agents water quality

There are a number of other media which are also pigmented with P.V.23. The list includes office articles and artists colors, such as drawing inks and fiber-tip pen inks, wax crayons, oil paints, and high quality water colors, water- or solvent-based pigmented wood stains, cleaning agents, and mass colored paper.

Everything we put down the drain or flush (down the commode) ends up in our watersheds which can affect the health of terrestrial and aquatic wildlife, plants, the atmosphere, and the water quality in our area. Residential and commercial use of chemicals constitutes a very large, nonpoint source of environmental contamination. A typical source of environmental contaminants are products used for household use such as cleaning agents, surfactants, pesticides, fertilizers, lawn and garden treatments, paints, sealants, and even discarded or flushed medicines. It is imperative that those seeking a healthy lifestyle and reduction in pollutant exposure choose with care the products they use to clean and maintain their homes, yards, and pets.

Tamarind concentrate shall be obtained by hot water extraction of clean tamarind pulp, with subsequent concentration under vacuum. The tamarind fruits shall be mature, sound, fresh and shall be free from insect and fungal attack or any other blemish which affects quality. There should not be any added colouring or flavouring agents. 

When water samples collected from the field were spiked with the 6-endotoxin and tested, sensitivity and precision of the ELISA procedure decreased regardless of the pH tested. Two procedures, anion exchange chromatography and dot-blotting, were explored for sample clean-up and concentration when sample work-up is needed. In addition, problems with assay development are also discussed. As more biochemical agents are introduced into the agricultural market, derived either from classical or molecular approaches, it is critical that analytical methods are in place for quality control and to monitor the presence of these agents in the environment.
