Are enviro-nuts EVER satisfied??

Catalytic converters: source of pollution?

Massachusetts scientists say toxic metals from automotive catalytic converters have been detected for the first time in U.S. urban air.

The research was conducted by Swedish scientists working in collaboration with researchers from the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution.

The scientists found high concentrations of platinum, palladium, rhodium and osmium in air over the Boston metropolitan area. Although the particles are not yet considered a serious health risk, evidence suggests they potentially could pose a future danger as worldwide car sales increase from an estimated 50 million in 2000 to more than 140 million in 2050.

Finding ways to "stabilize" those metal particles within the converters "should be a priority to limit their potential impact," says lead researcher Sebastien Rauch of Chalmers University of Technology in Goteborg, Sweden. Scientists have also detected elevated concentrations of the elements in Europe, Japan, Australia, Ghana, China and Greenland.

Catalytic converters reduce emissions of carbon monoxide, hydrocarbons, nitrogen oxides and other pollutants.

The study is to appear in the Dec. 15 issue of the American Chemical Society's journal, Environmental Science and Technology.

Old news. Not much different than the special low emissions fuel developed for California, which turned out to damage engines and release unexpected pollutants.

And no, the enviros are never satisfied. Just look at many of the issues they support...

At some point I expect one of these groups to do a study on human output of carbon dioxide and biological waste with a plan for population reduction. But the avian influenz HN51, ebola, will take care of THAT problem

But wait? Another reason not to worry about this study. Aren't we going to run out of oil by 2050, and costal cities like Boston dissapear into the ocean due to global warming, washing away all of the platinum, palladium etc from the streets of Beantown?

Oh no! We're doomed!

While there is some need to be watchdogs on the environment, sooner or later the enviros will figure out that the best way to fix things is do away with humans... then they'll start killing themselves off "to save the earth". After they are gone, it may be a much nicer place.

Given half a chance, the earth repairs itself... whether by war, or disease, or natural catastrophe...

Heavy metals are pollutants.... you sound surprised. I didn't make it past grade 8 and I knew that heavy metals were considered carcinogenic.

I'm not sure what qualifies someone as an "enviro-nut", though. 10 years or more ago, I had made remarks that, even though we had found new methods and materials, we shouldn't get lax in our attitudes... history has shown that the excesses of consumers will ALWAYS overload ntures ability to deal with common compounds.

We slopped R-12 around with abandon.... AC systems, hair spray and whipped cream propellant and God knows what else. Now, many are guilty of slopping R-134a around like it was water.... the same R-134a that was originally to be a "stop gap" safer replacement for R-12. How long before someone discovers the dangers that this particular excess will deliver upon us.

FWIW, I spent most of my childhood on Canadian army bases.... asbestos was the insulation of the day. My job includes daily "ablutions" in carcinogenic liquids, chock full of heavy metals and Lord only knows what chemical changes..... Am I ill... well, I suffer from the ravages of aging and the toll my daily tasks take on me...

However, our lifestyles have overtaken us. Fresh fruit and vegetables weren't good enough. We first had to force this stuff out of the ground with chemicals, bypassing that "je ne c'est quois" that nature gave it. Then we had to process it and "enrich" it and add chenicals to it and add a label that says "MAY CONTAIN..." I'm putting this shit in my belly... can we please come up with something better than "MAY CONTAIN....".

It doesn't take a college degree to realize that everything we have grown dependant upon has downsides.... electricity - hydro-electric can change the way a river works, atomic power (what can I say).... wind and tidal generators will also surely have an affect on our planet. The things we do, the way we do them, the things we eat and the way we grow them.....

Just as we can be sure that Rich will find another alarming report to post in it's entirety (palgiarism and originality notwithstanding), we can be just as sure that tomorrows advancement can easily turn into next years problem.

I don't think that it's the bad things by themselves that will do us in.... it is our excesses that will do that.

Has it occured to you that we should keep trying until we get it right? If not, then what legacy do we leave to future generations?

Yep, she does. and we may not like the way she does it.

Yeah, on the other hand, my car with no cats just passed emissions. Locally (Alb, NM) they've adopted the OBD-II emissions testing without any sniffer in the tail pipe. My car is completely healthy from the perspective of the OBD-II systems so I passed the test. There is, currently, no visual inspection, so the straight pipes, while raising questions, did not cause my car to fail. And I can put a pair of empty cat cans on for the visual and still pass since my car is healthy according to the diagnostics.

The point is, cats may become superfluous on vehicles later than 1996.

An environut is someone who constantly runs around shouting 'the sky is falling" and posting all manner of gloom and doom reports to instill fear in others, as if the news has just been discovered, even though it might be years old...... Oh, wait! That's Rich.....

A large number of us who live under constant attack from environmentalists consider there to be different degrees of environmentalists.....

There are those who truly care about the environment, but realize that there is no way to absolutely fix all the problems as long as humans are involved, so they are willing to work together and compromise.... they drive classic cars which they keep tuned and in good repair.

There are those who are environmentalists because it's the in thing to do... they work in Hollywood and drive exotic cars and replace it when the tank goes dry.

There are those who are environmentalists because of the drugs they took while residing on the communes raising pigs during the 60s... they still drive their VWs.

There are those who are environmentalists for money... they still have fine Corinthian leather seats in their cars.

There are those who are environmentalists who would just as soon turn the earth into a nature preserve and kick all the people out. This is a small elite group headed by Al Gore and go by the organizational name EnviroNuts or EnviroNatzis and believe there can be no middle ground where plants and animals are concerned.

You seem to have ingested too much lead as a young child. Maybe you can reverse the effects by snorting some asbestos dust. Be sure to wash it down with a good does of DDT...

Ever wonder who benefits from the 150 MILLION U.S. taxpayer dollars spent each DAY in Iraq?

The future generations will have far more advanced technology that will allow them to better deal with any problem we might choose to tackle. Leave it for them.

Catalytic converters are like hydrogen fuel; All the environuts want them/it, but never stop to consider what is done to PROVIDE the materials to make them. In the case of platinum, an ingredient in converters, it's the clearing of the plant life, the blasting, the digging, transporting, crushing, processing, refining of one ounce of metal from at least 25 tons of rock. How much energy and pollution do you suppose that creates in whatever backward country it's done in?

Of course the average age is longer now than years gone by..... diseases that were once killers are now either treatable or otherwise beatable. Polio, measles, rubella, scarlet fever... the mortaliy rate was extremely high. We can attribute the greatest portion of our longevity to medical advancements with a healthy dose of improvements in food storage.

Interestingly, one device that improved food storage - the every present refrigerator - was part of the problem as we treated cfcs with a cavalier attitude.

Getting back to carcinogenic..... in place of those old ads I remember as a child.... the one's featuring a youngster striken with polio in an iron lung. We now see ads fr those striken with diseases that people didn't live long enough to get.

Years ago, we had neither air quality warnings nor people getting skin cancer from lying in the sun. We didn't have a lot of things we take as common-place today.

The notion of zero pollution is unattainable... but we should all do our part to minimize the impact our daily lives have on our surroundings. We don't have to be raging environmentalists to use our non-renewable resources with a sensible mind and we aren't enviro-nuts if we realize that there are correct ways to dispose of some of our modern refuse.

Imagine that the world was limited to your backyard..... you can only shit in your backyard for so long before it becomes a really unpleasant place to be...

The world is a wide place... we can't look at it with narrow vision.

Like what? Or are you just speculating? Probably the thing I can't stand the most about all this are the hypocrites who NEVER practice what they preach. Give up your car, give up heating your house or using electricity, because they ALL pollute. Ride the 30 miles you have to to go to a grocery store (and only buy organic produce at 3x the price) on a bicycle during a -40 deg. Alberta cold snap!!!!!
