The World Health Organization (WHO) recently raised the risk warning on several common pesticides to "probable" carcinogens-and now an environmental lobby group wants their use restricted in parks and gardens.
The Advocate Precautionary Principle (APP) group says there is now enough evidence to stop the use of the pesticides where children and pregnant women often gather.
Its recommendation follows a report by the WHO's International Agency for Research on Cancer that raised the risk level from possible to probable carcinogens for the herbicide Glyphosate and the insecticides Malathion and Diazinon.
Glyphosate, which is the active ingredient in Monsanto's Round Up range of weed killers, has been found in air and water samples and in food. People who live near sprayed areas or gardens are at higher risk for developing cancer.
In its call for a ban, the APP says that it's now established that pesticides cause acute and chronic health problems, and that doctors need the training to identify cases of pesticide poisoning.
