GRAFTON (AP) - Some of the farm chemicals picked up in this year's record-setting Project Safe Send collection are considered highly toxic. Still, officials say they're typical of the old and unused pesticides brought to collection sites each year.

DDT, chlordane and toxaphene were among the chemicals picked up by the annual state pesticide pickup organized by the state Agriculture Department. The Stockholm Convention on Persistent Organic Pollutants, a United Nations-sponsored treaty, included the chemicals on its "dirty dozen" list.

Spokesman Ted Quanrud said chlordane is banned worldwide. He said toxaphene is an insecticide used as a cattle dip for scabies.

Quanrud said Project Safe Send also picked up Paris Green, a pesticide once used back in the Dust Bowl years to keep grasshoppers from entering wheat fields.

The department said this year's statewide collections brought in nearly 100 tons of pesticides, topping the record set in 2002. Project Safe Send is funded through registration fees paid by pesticide makers.
