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.
