The US will sign an international treaty to control persistent organic
pollutants (POPs) at a convention in Stockholm next month. The announcement
comes weeks after the US unilaterally rejected the Kyoto Protocol to stem global
warming. Known as the 鈥渄irty dozen鈥�, POPs comprise 12 toxic pesticides and
industrial chemicals, including DDT and dioxins. 鈥淪ome nations have a harder
time addressing these threats, and this treaty promises to lend them a hand,鈥�
said George W. Bush.
