Some say NO mercury should be placed into the environment; that it should be a closed loop with no loss at all or should not be used.
Dumb, devil's advocate question from a Sierra Club member with a sense of irony:
Isn't mercury already "in" the environment? If not, where did it come from?
Mercury never existed untl it was invented by Wicked Chemical Cartels!
...and who developed a 100% polution free process which never was commercialized by EK. Its effluent was drinkable water.
There was a clip on one of the news shows about one guy in Bollywood. He has done 14 feature films in 2006. Those weren't bit parts either. He starred in that many. Imagine if Hollywood pumped out films at that rate.
Jack;
There seems to be something to add to your reference that was left out for good or bad.
The mercury emission from a coal fired electrical plant is distributed over the earth in the atmosphere and the mercury emission from the bulb is concentrated at the place where it is disposed of and then this concentrate gets into the soil as a direct contaminant. Assuming recycling, even that is lossy and some mercury would probably get into the environment.
What is worse, 2 mg of mercury in a small stream running out of a waste site or 4 mg of mercury being emitted from the stack of a power plant and dispersed over a whole city? The amount per unit area is actually lower in the scond case, I suspect.
IDK which is worse, but I assume that they are both equally bad in spite of one being neary 2x greater than the other. The problem is, no one really knows for sure and that is part of the whole problem. Some say NO mercury should be placed into the environment; that it should be a closed loop with no loss at all or should not be used.
This is the problem. And, considering the amount of coal used for lighting vs coal used for running other equipment, lighting is only a part of the problem, not all of it. If everyone converted to fluorsecent lights and then lighting use was included in overall power consumption, we might not even be able to detect the difference.
People just jump quickly to a conclusion. 'This is better than that', with a 'statistic' to show, but it has been said that anything can be proven with statistics.
Mercury is bad. We should eliminate its use or escape into the environment. The fluorescent bulb is not all of the answer and may not even be the best one.

but as I recall, US interior doors are crap too.

Let's not forget that India has a population of roughly a billion. And movie pictures are more important there than here. They have mobile cinemas to entertain the people in the rustic areas... We on the other hand are couch potatoes who don't go out to the movies because there are 100 other entertainment options.

By the way, does the Indian cinema still rely on the film today?
... Companies that do not produce color or motion picture films rely solely on production of their B&W film and paper. Market fluctuations or declines must be directly reflected in production schedules and prices.
**** I do not get what is a problem here

What needs to happen is that the manufacturers need to understand the artistic integrity in film. All the great Black and White art photographers still use film. The ones I have spoken to know there is no substitute for a large format negative. These are people who many of you may have heard of and are truly legends of photography. Museums and art dealers need to help our cause as they also know there is no viable substitute for the longevity of silver based photography. I can't not even begin to tell you how ridiculous I find it that Kodak is striving to become all digital. There is room for both means of photography and the companies that pioneered such traditional methods need to understand the importance of not abandoning traditon all together. If they wish to stop coming up with new emulsions, that is fine as long as they keep the time tested winners available.
Mercury occurs naturally at low level in the environment as mercuric oxide or other mercury salts. It is not found in the air except as dust from natural ore deposits, and never as a free metal. I was referring above to mankinds augmentation of mercury release through TV tubes, electronics and fluorescent bulbs among others. We used to use mercury salts for merthiolate and skin lotions such as calomine

I seriously don't know why if they made them in the past, they can't build new smaller, more efficient coating machines now for less output???????? I understand that it's not "that easy", however there must be ways to do this.
