It was not possible to make any detailed assessment of trends due to the haphazard nature of the existing analyses. From the existing data the most significant POP appeared to be DDT which was used for indoor spraying according to WHO guidelines. Most countries have a ban on other uses of DDT but unauthorised uses have not been ruled out. Dieldrin and aldrin have been used mostly for termite control but this has been phased out and banned. Although not a POP chemical, it was noted that methylbromide will be phased out under the Montreal Protocol.
Obsolete chemicals remain a problem in all countries and dealing with it is extremely costly.
There are no suitable incinerators in full-time operation in the region to dispose of these. In discussing further information needs, the shortage of suitable analytical facilities was again emphasised. The problem of easily identifying POPs through suitable labelling was mentioned and ongoing work under the IFCS in harmonising the classification and labelling was noted. Information on risk assessment and exposure to POPs was needed by most countries and it was agreed that networks must be expanded throughout the region. The major barriers are lack of funding and human capacity.
