Italy still strugle from the catastrophe where 1 kilogramm of dioxin was relized in nature in 1976. http://en.wikipedia.org/wiki/Seveso_disaster

And also 6 tonnes of other crap; further, I'm not terribly impressed when I read about 0 increase in all-cause mortality decades after the disaster, countered only by a later paper that smells like datamining ('neoplasms'? really? where's my all-cause mortality? That's what we care about!)
