Hazardous Chemicals: Overview, Toxicological Profile, Challenges, and Future Perspectives offers comprehensive coverage of hazardous chemicals and their routes of exposures, mechanism of toxicity, hazard control measures, handling and storage, emergency guidelines, and safety measures. The book is organized into specific classifications of chemical hazards: pesticides, fertilizers, insecticides, automotive, paint and paint solvents, chemical manufacturing solvents, dyes, cleaning agents, pharmaceuticals, and radioactive products. It discusses the health risk and environmental impact of these toxic substances. It also provides management strategies including risk assessment, risk management, and risk communication. Hazardous Chemicals is a practical resource for researchers, academics, industry professionals, graduate and postgraduate students in toxicology and environmental science engaged in the evaluation of toxic substances and human health concerns.

Dendrimers referred as the ¿Polymers of the 21st century¿ have advanced from a concept to become a new category of polymers with a novel architecture, high loading capacity and versatile chemical structures. The key factors that facilitate steady increase of its application are non-toxicity, multifunctionality, Biodegradability, and nonimmunogenicity of dendrimers. Recent advances have generated avid studies at the frontiers of organic, inorganic, supramolecular and polymer chemistry. This book covers physico-chemical properties, classification, approaches for dendrimer synthesis, characterization, along with their potential applications in areas of research, technology and treatment like dendrimers for targeted drug delivery, gene delivery, printing inks and paints, cosmetics, light harvesting materials, and waste water treatment. This book clearly demonstrates the various applications of dendrimer and indeed substantiates the high hopes for green future.

The Science and Technology of plastic coatings is described in a comprehensive and clear manner with the basic chemistry and their properties of coatings. Also described are the function of coatings and manufacturing technology and their applications in electronics. Plastic coatings are a relatively youthful field offering exciting challenges and carrier opportunities. Any given coatings are more technically challenging than the so-called pure research. Any given coatings must meet a given set of requirements. There are innumerable possible raw materials, combinations and proportions. Test methods are highly error-prone and do not give results that predict well performance. The formulator is faced with variable substrates and application methods. There are also other factors like cost constraints, time constraints etc. in fact, as one looks at the complexities of the field, one sometimes wonders how a useful coating ever gets formulated. The plastic coatings for an electronic component like circuit boards, electronic assemblies, coil, and wire worked in the laboratory, which is based on the formulation.
