Canada said March 31 it would launch a new review of the commonly used agriculture herbicide atrazine to specifically study whether it makes drinking water unsafe.
The announcement of a came on the same day the Pest Management Regulatory Agency said another review, , found no new restrictions were warranted on use of the pesticide in Canada.

Atrazine, primarily produced by Swiss chemicals company Syngenta, is used to kill broadleaf weeds in corn and sugarcane crops, as well as in turf, such as golf courses and residential lawns. It is commonly used in Canada, the U.S. and Australia, but was banned in the European Union in 2004.
