One-third of backyard soil unsafe to grow vegies

Macquarie University/The Lighthouse New research has found Australian backyard gardens near busy roads and in older homes often have high levels of lead and other contaminants in their soil, making them unsafe to grow food. More than a third of the soil tested across thousands of Australian homes had unsafe levels of lead, according to new research from Macquarie University’s VegeSafe, the largest citizen science program of its kind. Digging deep: Research Fellow Dr Cynthia Isley, Master of Research student Kara Fry and Professor Mark Taylor in the lab at Macquarie University. “Our program has helped thousands of home gardeners across Australia make sure the food they grow is safe to eat,” says Professor Mark Taylor, an environmental and human health scientist at Macquarie University who set up the VegeSafe program in 2013.

Toxic secret in Aussie backyards

Toxic secret in Aussie backyards Australians are increasingly growing food in their backyards but a new study has found dangerous levels of contamination could be exposing children to risk. Home & Decorating by James Hall 5th May 2021 5:46 PM An expansive survey of Australian soil samples has found more than one-third of vegetable gardens across the nation could produce food containing dangerous levels of lead. The study, led by Macquarie University and published in the journal Environment International, tested samples from more than 3600 Australian homes, including 1530 from Sydney. It found 35 per cent of vegetable gardens across the country had levels of lead that were above the Australian guidelines for homes with gardens that produce food or are in contact with the soil , according to study co-writer Cynthia Isley.
