Rome fell after they stopped using lead. There is no evidence whatsoever that lead was widely known to be toxic, until a group of conspirationists took over the academia. In fact such a belief couldn't have been widespread. The historical quotes appear to be fabricated. In fact it's essential. Roman sewers and sanitation quickly flushed it down the drain, by 235 it was in chaos, long distance trade was no longer possible and a thousand years long dark age ensued. The original depletion happened deep in prehistory, the most major event happening around 26kya. Also by ice cores, substantiated by geological changes and mammoth skeletons.
