The data available on the Indian POPs pollution scenario shows need for every concern. But the interest shown by the concerned agencies is very minimal for reasons obvious. The participation by NGOs and public is not encouraged in this critical issue. Effort by the scientific community is waning for want of encouragement and should be stimulated in a systematic and coordinated fashion. As a first step to this, available information on the existence of PTS, their distribution, transport and bioaccumulation in the Indian environment and biota should be gathered in a systematic manner.

Part II of this book represents the bulk of the material on the analysis and modeling of biochemical systems. Concepts covered include biochemical reaction kinetics and kinetics of enzyme-mediated reactions simulation and analysis of biochemical systems including non-equilibrium open systems, metabolic networks, and phosphorylation cascades transport processes including membrane transport and electrophysiological systems. Part III covers the specialized topics of spatially distributed transport modeling and blood-tissue solute exchange, constraint-based analysis of large-scale biochemical networks, protein-protein interactions, and stochastic systems. 

T(he increasing development and use of insecticides and other pesticides constitute a growing hazard for contaminating our water supplies. To keep pace with the use (5,6) of these toxicants, more information is needed on distribution, transport, exchange mechanism, degradation products, and metabolites of these substances. Thus, convenient and sensitive methods of analysis are essential to the success of research in this field. Furthermore, pesticide levels in water can be monitored more accurately by improved analytical techniques. Accurate and rapid procedures are especially needed when prompt information or action is necessary. Even when low concentrations of pesticides do not show immediate adverse effects, detrimental results may eventually occur, since it has been observed that a number of these toxicants are concentrated in a variety of aquatic plants and animals.

In natural water, trace metals can be present in the form of free ions, complexes or organo-metallic compounds. They also may be adsorbed onto particidate matter. Many phenomena affect the distribution of trace metals between dissolved and particulate forms when they enter estuaries, having been transported by rivers. The origin of these phenomena is that the metals are exposed to an environment with increasingly different physical and chemical characteristics. In order to understand the distribution, transport, bioavailability, etc., of trace metals, their physico-chemical...

A further OECD Council Decision in 1991 focused on HPV chemicals. These decisions prompted the development of a minimum hazard data set to describe an HPV chemical - the Screening Information Data Set, or SIDS. This includes physicochemical properties (melting point, boiling point, vapor pressure, water solubility, and octanol-water partition coefficient) environmental fate (stability in water, photodegradation, biodegradation, and an estimate of distribution/transport in the environment) environmental effects (acute toxicity to aquatic vertebrates, invertebrates, and plants) and human health effects (acute toxicity, repeated-dose toxicity, toxicity to the gene and the chromosome, and reproductive and developmental toxicity). 

A recent case-control study in a cohort of about 100,000 male refinery workers from five petroleum companies revealed no excess in kidney cancer in refinery workers (Poole et al. 1993) The relative risk for any exposure above refinery background levels was estimated to be 1.0. In contrast, workers involved in the distribution, transport, and movement of petroleum products (job category... 

The storage, trade and distribution of pharmaceutical products are carried out by various companies, institutions and individuals. The nature of the risks involved, however, is likely to be the same as those in the manufacturing environment, e.g. mix-ups, contamination and cross-contamination. There are thus aspects of distribution to which the principles of GMP should be applied. These include, but are not limited to, storage, distribution, transportation, packaging, labelling, documentation and record-keeping practices.
