OK , now it's time for a broken down old man who got his qualifications in the 70s to remind the EPA scientists how epidemiology and toxicology work in the real world.
On Aug 19th in downtown Pittston, some of the planets best tasting tomatoes were thrown around celebrating yet another year of great crops. If our liberal friends did not have their heads up their rectums, the science of coal ash toxicity was there to observe.
It's cold this morning and I am bored so read awhile.
Let me explain how you determine if things are toxic. We can separate out acute and chronic toxicity easily. Cyanide is toxic, I take some and I die, yep it's toxic. However, how about if cigarette smoking has an effect on cardiovascular desease. I have a cigarette and I don't die. I smoke 100 cigs and I am still fine, how do we determine cause and effect? The best study ever run was the 1948 Framingham srudy and EPA scientists will acknowedge that one. This is a coal board so I will just Wiki the reference. http://en.wikipedia.org/wiki/Framingham_Heart_Study
Now coal ash does have toxic compounds embedded and releasing millions of tons into a river is never a good idea and should never happen again, however, assessing the relative harm associated with ash and for example CO2 is a matter of benefit/risk. That is what Sam and his hoards of uneducated lunies never care about. The stupid law of best practices is an unending quest for the holy grail without worrying about costs.
So let's get back to the humble Pittston tomato.
Here we have a classic Framingham-type database spread over 100 years at least. NJ tomatoes are grown in soil but in Pittston crops are grown in mine rock, coal ash and culm. So we have two distinct populations, near to each other and the effects of coal ash can be statistically studied. So we do that? No of course not, we just rabbit on about best practices. We are governed by idiots that that were elected by morons.
Cancer clusters and clusters of radioactive poisoning and clusters of cause and effect on just about anything are drawn up on global maps for the educated to study. I have some of these (now very outdated) atlases. I can tell you many things like we were idiots to let marines get exposed to radioactive clouds of dust in the 50s. I can tell you how many millions will die from Fukushima (yes, millions). We can tell you how many will still die from Chernobyl and I can tell you next August I am going to Pittston to throw tomatoes around and eat the local produce.
Now don't get me started about CO2.
