The environment in which human beings live is complex and we may encounter many different potentially toxic chemical substances during the course of our lives. These xenobiotic agents may invade the living system in the form of environmental pollutants, in the diet, as pharmaceutically administered compounds or even as chemical weapons and it is becoming widely recognised that free radicals are often involved in this toxicity.
The book covers all aspects of toxic agents in the environment from their detection to their effects. Final year undergraduates and postgraduates studying...

Studies of free radicals on surfaces are of interest for several reasons: the spontaneous or stimulated formation of radicals from adsorbed molecules may represent one possible mechanism for heterogeneous catalysis. In some cases the radicals are ionic, indicating that primary oxidation and reduction reactions occur. Radicals can also be used as probes to investigate diffusion processes on catalytic surfaces. The first direct observations were made more than 30 years ago, but detailed studies of structure, reactions and mobility have only recently become feasible with the advent of powerful...
