Heavy metals are often found in urban backyards.
The heavy metals and metalloids which pose the greatest risk to human health when found in soil are Arsenic, Cadmium, Chromium, Copper, Manganese, Nickel, Lead, and Zinc. These heavy metals when ingested have been linked to cancers, kidney, bone and nerve damage.
In urban areas, the heavy metal of most concern is lead, which may have accumulated in the soil due to the past use of lead-based paints on old houses, sheds and fences and from the emissions of cars run on leaded petrol before it was phased out.
Soil naturally contains small amounts of lead in the range of 15-40 parts of lead to one million parts of soil (ppm). In some urban areas however, lead levels in the soil may be as high as 500 - 10,000 ppm which is way above the safe level of 300ppm in Australia.
