When you get deep into these widespread public health issues you start to realize that there's always going to be at least one that you or your locale is at risk for. If it's not the water, it's the food. If it's not the food, it's the air. If it's not the air, it's the soil. If it's not the soil, it's your building. And so on...
The best you can do, in the end, is to avoid paranoia or panic and just aim for some systematic detection, mitigation and prevention processes in your household. With a little luck and a good system, you cheat death or disability, temporarily. You cannot create an ironclad guarantee of safety, but there are many things that you can do something about.
I figure tallying the top ones based on impact on life expectancy makes some sense. The list is probably going to be dominated by the top two or three items. Probably obesity (4 years?) followed by air pollution (1 year maybe) in my case. Not much point worrying about the barely detectable stuff.
