On the subject of motion picture films, I have read in a few areas that India was one of the largest users of these films. I am not sure if they surpass Hollywood in this, but I found the statements about India somewhat surprising.

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.

Jack;
Are you using a flat screen monitor or a tube monitor? If so, one contains selenium and arsenic and the other contains lead and mercury. The computer contains both selenium and arsenic. If it shorts out, and you smell a garlic like odor, then that is the arsenic. It happened to me once.
What is the power consumption of the monitor vs a reading lamp?
Do you use a gas stove or electric stove?
Do you use a gas furnace or an oil furnace, or maybe even coal?
Do you wash your fixed prints in running water or still water? Either way, the wash water contains hypo and silver.
Do you use selenium toner and then wash your toned prints in running water? That puts selenium into the environment.
I could go on and list all of the questionable things we all do. I agree with you and was not criticizing. I'm saying that we seem to just concentrate on one thing when a 'fad' strikes the media, but what we should be doing is working on ALL waste products and open loops. Some of us are and some are not, so my notes above are just to show how many many there are.

I spent a fortune putting high efficiency HVAC in...I'll spend another one on tighter doors and windows.
My door and windows fit REALLY BADLY -- so I wear more clothes in winter...
...at the risk of asthma and a weakened immune system.

I want to be able to control air exchange
I thought that was one of the advantages of living in rural France.
Oh no you don't. That way asthma lies...
