how hazardous are these substances really ?
I am using our kitchen for developing my b&w films and now I am wondering how hazardous the chemicals I use realy are. This is what I use:
- XTOL developer
- TMAX fixer
- Ilford Iflostop
- Tetenal Mirasol 2000 Antistatic
- Kodak Rapid Selenium Toner
- lots of distilled water
- TMAX film
Especially the selenium toner and the fixer smell very ... unhealthy.
About the toxicity of selenium wiki says the following:
Sounds pretty scary ...
Although selenium is an essential trace element, it is toxic if taken in excess. Exceeding the Tolerable Upper Intake Level of 400 micrograms per day can lead to selenosis. Symptoms of selenosis include a garlic odour on the breath, gastrointestinal disorders, hair loss, sloughing of nails, fatigue, irritability and neurological damage. Extreme cases of selenosis can result in cirrhosis of the liver, pulmonary edema and death.
For each of the mentioned chemicals Is it ok to
- work without gloves
- inhale their perspirations (work without mask)
- spill the used chemicals into the toilet
- spill the used chemicals into the kitchen sink
- generally use them in a kitchen (no matter how careful I am, I am sure some drops of the chemicals end up at places where food or dishes will be later, especially near the sink)
