Asylum Seekers in Greece at Risk of Lead Poisoning, Activists Warn Anthee Carassava ATHENS - Bullet casings, weapons and unexploded mortars have been found at a military firing range-turned refugee camp in Greece, endangering the lives of thousands of asylum seekers and aid workers. International activists, though, are most concerned about potential lead poisoning which the heavy metals and their residue have left behind. The shocking revelation comes amid calls by Human Rights Watch for authorities on the island of Lesbos to suspend ongoing construction at the Kara Tepe camp and instead survey the soil of the former firing range for ordnance and potentially poisonous concentrations of lead. "Academic research has shown that firing ranges are sites with soil lead contamination, meaning that anyone living or working on a former firing range could be exposed to lead through dust or soil,"said Katarina Rall, a senior researcher at HRW who was involved in an extensive study of the Kara Tepe camp. "So based on the research, we are concerned about the risk of lead poisoning for those living and working there, in particular, small children and pregnant people." .
