Published in 23/1/2014
Researchers did not discourage agriculture in cities, but point out the risk to human health that may be present.
Urban gardens are becoming increasingly popular,and as such, were, for the first time, evaluated by the researchers from the department of Chemistry and CESAM. Based on samples collected in the area of Porto, the results showed that levels of some metals, such as cadmium, copper, lead and zinc, exceeded the values recorded in natural areas away from contamination sources - such as roads and airports - but also exceeded the maximum values imposed by the EU.
