The sol-gel-entrapped microbial cells have shown excellent tolerance to different alcohols [99], The immobilized E. coli cells followed the Michaelis-Menten equation when quantified with the (3-glucosidase activity via the hydrolysis of 4-nitrophenyl-(3-D-galactopyranosdie [142], The sol-gel matrices doped with gelatin prevented the cell lysis, which usually occurs during the initial gelation process [143], Microorganisms are now widely used in the biosorption of different pollutants and toxicants. Bacillus sphaericus JG-A12 isolated from uranium mining water has been entrapped in aqueous silica nanosol for the accumulation of copper and uranium [144], Premkumar et al. [145] immobilized recombinant luminous bacteria into TEOS sol-gel to study the effect of sol-gel conditions on the cell response (luminescence). The entrapped and free cells showed almost the same intensity of luminescence (little lower), but the entrapped cells were more stable than the free cells (4 weeks at 4°C). This kind of stable cell could be employed in biosensors in the near future.

Thoroughly referenced from a wide variety of sources, this book contains information on industrial solvents, pesticides, metals, air pollutants, and toxic gases and drugs, as well as other substances. The information presented for each chemical substance is concise yet thorough and does not require advanced training to comprehend. For each chemical, the author provides the CAS number, lUPAC name, molecular formula, synonyms, uses and exposures, toxicity and health effects, the exposure limits, and methods of proper storage and disposal. Tables and appendices are included where appropriate.

Surfactant-modified cellulose fibres appeared to be effective sorbents for the removal of organic compounds dissolved in aqueous media. Given the ready availability of this type of substrate and its low cost, the present approach could be promising in applications related to the removal of organic pollutants and toxic substances in wastewaters. However, the adsorbed surfactant molecules were found to desorb from the cellulose surface during the recycUng of the substrate [29], limiting its possible use for multiple adsorption cycles in a... 

On the other hand, there is the over-increase of world population and its related problems it has been claimed that humans have already exceeded the planet s ability to sustain their level of consumption, known as Earth s carrying capacity , by about 20%. That figure is expected to climb as more than 2 billion people living in India, China and other developing countries raise their standards of living in the near future, which will certainly cause ever-increasing pollution and toxic effects, unless more careful measures are planned and put in action.
