NEW DELHI: The fate of a toxic chemical is yet to be decided in India, despite 90 nations voting for a global ban on its usage. Pentachlorophenol (PCP), a persistent organic pollutant (POP) which is mainly used as a wood preservative in India has been banned completely at the Conference of Parties (COP) 7 of the Stockholm convention held earlier this month in Geneva. Exposure to PCP is even linked to certain types of cancers.
