Academics helping Ukrainians to study soil in bomb-hit farmland say have found surprising levels of contamination in some craters.
Professor Nicola Cannon said: “The farmers are a very resilient bunch. The problem is if they just put the soil back into the holes.”
They have initially tested 28 craters, uncovering samples of mercury and lead.
“If there was something like mercury or lead or, worse than that, like depleted uranium in the bomb, then with the cultivation, that could end up in the food chain.”
Contamination by heavy metals has the potential to impact human health long after the war has ended.
Prof Cannon said: “We’ve seen levels of mercury, lead, various metals, copper….which was surprising as it’s such a valuable element, but we found one crater had very high levels, which probably means some was stuck in a bomb.”
To work out how to find polluted soil, RAU staff, alongside researchers from Sumy National Agricultural University (SNAU) in Ukraine, developed a sampling method on Salisbury Plain in Wiltshire.
Soil samples are then analysed using specialist equipment from the RAU’s Cirencester campus.
Trainers are now being taught to show others http://selerapedas.com/ in Ukraine how to check bomb craters.
Prof Cannon said: “These farmers cannot afford to wait until the end of the war to correct land which has been damaged and contaminated by bombs.
“They need immediate, and ongoing, help to know what parts of their land are safe, and unsafe, to use for crops.”
