Catalan data from European Pollutant Emission Register on Google Earth/Maps

People tell me that emission reporting is routinely fiddled in Barcelona, as is monitoring by local authorities, and the true location of Spanish polluters–crucial for studying health effects–seems to be vague at best, but this (quite old) collection for GE gives us a handy way of discovering interesting stuff like, oh, the Gonvarri metal treatment plant near Castellbisbal on the Llobregat was delivering 382kg of zinc and compounds annually to water, from which I assume a small quantity makes its way into the water you drink in down-town Barcelona. Pic of part of the neighbouring Celsa facilities (CO2 to air = 162,000,000kg, cadmium and compounds to water = 252kg) here.
