Um
Hg compunds amalgamated with other substances leaches quite easily into water. Elemental Hg will bind like nobodies business with iron and will not leach into the water table. hence when you crush a fluorecent lamp into a pulp in a landfill, the HG will bind up with any Iron near by. There is Federal test, Toxicity Chracteristic Leachate procedure test which dictates what is acceptable, the product I worked on was modified to pass this test.
per Hg in fish, depends on what you concider toxic. I dont buy all the hysteria over it but I guess if your concerned dont eat it. Also doesnt it occur to you that Hg, in vapor form in the atmosphere is what is dumped into the oceans? Or Hg in various forms in the enviroment naturally will leach into rivers and streams. Most Hg is Primarily from coal burning power plants. We could get rid of fluorescent lamps and use more power and hence put even more Hg vapour in the sky
There is a study which assume we outlawed fluorescnt lamps and used Incandescent lamps and assume the same % of power from coal would result in about 1000 times more mercury pollution into the environement vs lamps. So there you have it, stop reading the media drive by articles LOL
From wikipedia:
Quote:
Unlike many other metals, iron does not form amalgams with mercury. As a result, mercury is traded in standardized 76 pound flasks (34 kg) made of iron.[15]
So do you know what you are talking about or just got things mixed up?
Anyways, I think the real issue is determining the level of effect on the population as a whole. Especially with things like heavy metal posioning. Some level of exposure will affect some part of the population, how much exposure and effects are acceptable is the question. Right now I don't really see many studies trying to determine this for Hg or anything else.
