CHM310H1 Lecture Notes - Naphthalene, Anthracene, Phenanthrene
Document Summary
Persist in the environment, don"t undergo degradation, insoluble, semi-volatile, halogenated. Stockholm convention: international treaty signed to eliminate or restrict the production and use of persistent organic pollutants (pops), signed in 2001, implemented in. These compound not only accumulate, but also has the ability for long-range transport. Global distillation: releaser these compound at high temperature low latitude, then depend on their molecular property, they have more or less tendency to move around. Highly volatile compound, not highly soluble: dispersed globally with no preference. Low vp, high mw, high kow: does not really move. Mechanism through evaporation, and condense, in higher latitude, more likely to condense and stick around. Pops persistent in fat tissue of higher latitudes. Higher concentration of pops in the arctic ocean than in the tropics. Look at concentration of pops in tree barks. Pulse ; follow the pulse moving through the system.
