Ozone depletion global hazard

A mechanism of action describes the molecular sequence of events (covalent or non-covalent) that lead to the manifestation of a response. The complete elucidation of the reactions and interactions among and between chemicals, include very complex and varied situations including biological systems (macromolecular receptors, physical phenomena (thermodynamics of explosions) or global systems (ozone depletion). Unfortunately, this level of mechanistic detail is often unavailable but recent advances in molecular toxicology and others hazards, at the molecular level, have provided valuable information that elucidates key steps in a mechanism or mode of action. ... 

Global warming and ozone depletion are the two primary global hazards associated with chemicals production and use. Chemicals that have structural features capable of absorbing infra-red radiation have the potential to contribute to global warming (see Table 2.4). ... 

It is imperative that common global approaches are adopted in chemicals and hazardous substances management. While in the past, the approach has been more specific issue-based with clearly outlined boundary conditions (e.g., Montreal Protocol on Ozone Depletion, Stockholm Convention on Persistent Organic Pollutants), the current approach entails a globalised strategic integrated view. 

Global hazard examines adverse consequences that occur on a larger scale area and include stratospheric ozone depletion and effects of chemicals on global climate change. 

The selection of a suitable solvent depends upon many factors including environmental acceptability, acceptable toxicity, performance characteristics, flammability, and availability. Environmental issues include ozone depletion potential, contribution to global warming, and the potential to produce smog due to VOCs. Many used, spent, or some unused solvents being disposed of are classified as hazardous waste and are subject to annual emissions re-...
