Global distribution of persistent organochlorine compounds.

摘要: The global distribution of 22 potentially harmful organochlorine compounds was investigated in more than 200 tree bark samples from 90 sites worldwide. High concentrations organochlorines were found not only some developing countries but also industrialized countries, which continue to be highly contaminated even though the use many these is restricted. relatively volatile (such as hexachlorobenzene) dependent on latitude and demonstrates distillation effect, whereas less endosulfan) are effectively distilled tend remain region use.
