Shame it took humanity so long to figure out the dangers of lead before it got spread out all over the place, but this sounds like an interesting potential solution.
How is the situation in Norway? I haven't heard of any lead pollution since I've lived here, so I assume it isn't a problem. The water is sooo good here!
Yeah, that's true. I think we banned lead-based fuel in Norway in the 80s, and ammunition with lead was banned just 10 years or so ago.
It's not a problem in Norway (or any other rich country) anymore, except if you work at a place that handles lead. This would typically be if you are working with car batteries on a regular basis. You could of course get poisoned if you spend a lot of time in buildings that have very old paint, or store acidic products such as wine in containers made from ceramics. But there are no problems with the drinking water here in Norway at most times.
But what about third world countries???
The situation is much dismal in poor countries thanks to corruption and malfeasance.
In my country arsenic contamination is taking toll and to make it worse there is no one to take notice or do something about it.
Third world countries have a lot more problems with lead in their drinking water than industrial/rich countries. Regions with mining operations close to drinking water are probably the ones who are most exposed to lead poisoning. Maybe some countries even still allow to have lead in the fuel (I sadly have no idea)?
Arsenic contamination is also a huge problem that can have fatal consequences! It sucks that no one is doing anything about it, @xabi :(
