Should the production and use of chlorine and all chlorinated
organic compounds be halted, in view of their adverse effects on
the environment and human health? Those in favour argue that
certain chlorinated compounds (PCBs, DDT, CFCs, etc.) have large
negative environmental effects. The use of chlorine in
disinfectants leads to the production of chloroform, while bulk
products (PVC) contribute to the production of chlorinated
dibenzo-p-dioxins and dibenzofurans when they are burned. Those
against argue that chlorine and many chlorinated compounds are
essential in the control of human health (the prevention of disease
transmitted through drinking water that has not been disinfected),
and that chlorinated compounds are indispensable intermediates in
many production processes, representing a vast economic value. But
such discussions often ignore the fact that Nature contributes
significantly to the production of chlorinated organic compounds.
More than 1000 such compounds are known, and their contribution to
the biogeochemical cycling of chlorine is underestimated. Chlorine
is organically bound in large quantities to humic materials, and
natural production mechanisms are known for low molecular weight
compounds (methyl chloride, chloroform, chlorinated
dibenzo-p-dioxins and dibenzofurans). The role of these compounds
in the environment is largely unknown. Naturally-Produced
Organohalogens gives a complete overview of the present state of
knowledge on the subject, giving a much needed balance to the
argument sketched out above.
