Thread: USA: ALL Freshwater Fish Tested are Positive for Mercury

unfortunately the article omits the level of contamination , any mercury at all is contamination agreed , however just what amounts are we talking about here ?

^Aw Mid, don't ruin the chance for some creative hysteria by asking logical questions.....

Yes, "Hysterics" over neuro toxins in consumer foods.

100 Percent of Fish in U.S. Streams Found Contaminated with Mercury

(article continues..)
All fish were contaminated with mercury, more than 66 percent of them at levels higher than those set by the Environmental Protection agency as a "level of concern for fish-eating mammals," according to Reuters. More than 25 percent of the fish were contaminated at levels higher than those set as the threshold for human consumption.


The study is the first to focus on mercury contamination of streams, rather than lakes, reservoirs, wetlands or oceans. The researchers found the highest mercury concentrations in fish from the coastal blackwater streams of the Southeast. Apparently the combination of pine forests and wooded wetlands found in these regions transforms mercury very effectively into its more toxic organic form (methylmercury). Mercury concentrations were also high in streams fed from areas with a history of mining.

that is a concern , any indication of how much is actually entering the human food chain or are these sources quarantined ?

Good news for the Disease Care Megacorporations.

Quarantined? No, the test fish were taken from the streams. Store bought and farmnd fish are also showing elevated levels of contamination. ( in article )

I would eat farmed fish for anything, living in excrement high levels of antibiotics are used.

Corporate greed, (mandated by law, corporate boards must care about nothing but profit margins ) is rendering the entire food chain inedible.

Understatement of the year...

If you take a fish oil supplement be sure of its source for the above reasons

^Exactly how would you do that?

No suprise from the country that is home to the most polluted coastal marine ecosystem in the world.

So what, doesn't stop people from eating fish,, and sure as hell don't worry me,, mercury is worth a lot of money, altho I have not seen the prices on a flask for sometime,
I figure after they cremate me they can dip up a flask or 2 and pay for my funeral..

Mercury Transport in Stream Sediments of the Colorado Plateau, by William L. Graf © 1985 Association of American Geographers.

Abstract

Field, documentary, and laboratory analyses show that geomorphic processes are a central component in explaining the origins and transportation of the 2,200 kg of mercury annually deposited in Lake Powell in Arizona and Utah. Almost all the mercury in the lake is derived from weathering of natural source rocks in the lake's 279,000 km2 drainage area and delivered in fluvial sediments. Of the mean annual mercury input to the lake, 40 percent comes from a single tributary, the Green River. The Colorado River contributes 40 percent of the water to the lake, but only 6 percent of the mercury. Local Canyon Lands streams contribute only 9 percent of the lake's water but 36 percent of the mercury and 40 percent of the sediment. Downstream distribution of mercury in fluvial sediments of ephemeral streams is directly related to exposures of geologic units in the contributing drainage area. In the arid and semi-arid Colorado Plateau, mercury is not generally associated with fine particles, enrichment does not occur in the transition from host rock to stream sediments, and organic materials are largely absent from stream sediments and so do not play a significant role in concentrating mercury. The regional mercury budget shows a definite spatial structure: streams contributing large amounts of mercury to the lake either discharge large quantities of sediment or have extensive outcrops of particular geologic formations (Chinle or Morrison) in their drainage areas. Mercury in the Colorado Plateau streams demonstrates that understanding of chemical cycles in the natural environment depends in part on an appreciation of the spatial characteristics of the physical processes involved.

Who would have thunk that it's a natural occurrence? Surely Cheney is lurking somewhere behind the scenes. Nerrr yeah! I'm Dick Cheney and I ooze mercury! Nerr, yeah, see!

Perhaps that explains why yanks seem so odd

It's going to get a lot worse in other countries too.......for many years to come, since those new compact fluorescent tubes have a lot of mercury in them.

I wonder which mining company(ies) paid for this research?

I get it now... Ha ^
Musty has a second nic. to agree with herself on her conspiracy/subversion posts

Mercury has been around since time immemorial as it occurs naturally, and I would imagine that we have all eaten fish with mercury in it as we do other foods.

What worries me about farmed fish is that we totally rely on the companies to ensure that the food that the fish are fed on does not contain levels of pesticides and other chemicals which could harm us. Also the heavy use of antibiotics could be harmful.

So give me a fish caught by rod and line anytime from a fast moving stream.

See How lucky we are to be old fuckers.
God damn we will miss all the fun of the ones being born only partly assembeled and fucked in the head like Mustyclit keeps posting about because of bulldozing old buildings into the river.
Give a thinking human the tools and supplies and he will fuck up a shit samdwich in a hurry.
Lucky we only got about 15 more years ..we will miss the best part.

^Your grandchildren and their children, will have to deal with it though.

Alarming Levels Of Mercury And Arsenic Found In Chinese Freshwater Ecosystem

ScienceDaily (Jan. 10, 2008) — A team of researchers, led by biologists at Dartmouth, has found potentially dangerous levels of mercury and arsenic in Lake Baiyangdian, the largest lake in the North China Plain and a source of both food and drinking water for the people who live around it.

The researchers studied three separate locations in Lake Baiyangdian, all at varying distances from major sources of pollution, such as coal emissions, agricultural runoff, and sewage discharge. They found concentrations of arsenic and mercury in fish were above the threshold considered by the U.S. Environmental Protection Agency (EPA) to pose a risk to humans and wildlife.
"It's important to study this system because it is typical of many throughout China where human activity and industrialization are having detrimental effects on the environment with major human health implications," says Celia Chen '78, a research associate professor of biological sciences. "It makes perfect sense to apply what we're learning about lakes in the U.S. to other places in the world, like China, that have a growing global impact."
Chen and her team were curious to learn how arsenic and mercury, two toxic environmental metals, moved through the food web in a freshwater ecosystem known to be polluted and contaminated. In a process called bioaccumulation, mercury and arsenic were found throughout the food web, from the water, into the algae, through the tiny algae-eating zooplankton, to the fish. As expected, the researchers found that more nutrient-rich environments supported larger algal blooms, which resulted in lower concentrations of mercury and arsenic in the water due to uptake by the algae.
In their previous work, the researchers found that when there is a lot of algae present, mercury and arsenic are biodiluted, or more dispersed, so zooplankton that eat the algae are exposed to lower levels of the metals and transfer less to fish.
"Despite this potential interaction - a decrease in bioaccumulation due to high algal biomass - the mercury and arsenic in this system are high enough to be of concern to humans and wildlife that drink the water and consume fish," says Chen. "For example, we saw arsenic levels in the water that represent more than fifty times the EPA-recommended limit for consumption of fish and shellfish."
Chen's co-authors include Carol Folt, dean of the faculty and professor of biological sciences at Dartmouth, Paul Pickhardt at Lakeland College, and M.Q. Xu at the Chinese Academy of Sciences in Beijing. Chen and Folt are both affiliated with Dartmouth's Center for Environmental Health Sciences and its Toxic Metals Research Program. Funding from the National Science Foundation and the National Institute of Environmental Health Sciences supported this work.
The findings were published online on Dec. 24, 2007, in the journal Water, Air, and Soil Pollution.

I give a fuck less, when my offspring hit 18, they are on their own, it is the way nature has it set up, Humans are the only ones that hang on to have control.

^Proof that some people should never have been able to reproduce. You sound like the kind of person who would leave shit smeared all over the toilet after you because it's not your problem who has to use it next. Idiot.
