Mercury increase in Great Lakes

Levels of mercury in pike and walleye increasing from: Minnesota Public Radio
February 17, 2009

St. Paul, Minn. — Mercury levels are increasing in pike and walleye in Minnesota. Minnesota Pollution Control Agency scientist Bruce Monson studied data from the past 25 years.

Monson found that from the 1980s through the mid 1990s mercury levels decreased, but since then they've been on the rise. Monson says that corresponds to an increase in global mercury emissions from 1990 to 1995.

"We're affected by global emissions. 90 percent of the mercury that gets deposited is actually from outside the state." [READ: China]

Minnesota has already greatly reduced its mercury emission levels, and it will cut emissions again by 93 percent by 2025. The state is also working with other states to push the federal government into take action to cut mercury pollution globally.

Drugs in Drinking Water

Environmental concerns about the quality of source water suddenly include the active ingredients from pharmaceuticals/drugs. And people wonder why they're told they ought not dump old prescriptions in the toilet as a disposal method? Or put them in a landfill? Hmmmm ... where are they supposed to go? One recommendation I saw a couple years ago was to return it to the pharmacy where you bought it, since they will have a disposal program for their own waste. Of course, theirs could be going into a landfill, too - it just won't go in the ordinary trash. oooh, any my home town is on the map with a cute red "tested positive" dot.

Wow ... what a concept. How are they going to explain parts per trillion? really, really small? Apparently since most of this stuff gets into the waters and sewers through human excretion, it might be an added incentive for more patient-specific dosing.
