Any causal relationship between asthma & brochitis and exposure to photo chemicals?
Question:
Most black-and-white photo chemicals are not volatile. There are only 3 things that might get into the air: (1) Powders from any powdered chemical. This shouldn’t happen; if it does, you’re damaging your photographic materials, not just your lungs. (2) Many people are sensitive to acetic acid fumes (stop bath). I’m one of them; to keep from getting asthma attacks I switched to a citric acid stop bath. Could this be your problem? Plain water works as a stop bath; you might try it. (Change it frequently.) (3) Sulfur dioxide (or some similar-smelling chemical) fumes from fixer. Not much of a problem with a non-hardening fixer (Ilford Universal). Again, switching to a plain water stop bath will, if I recall correctly, greatly reduce the emission of this gas. I do not know of any black-and-white chemicals in current widespread use that are highly toxic. Allergy to Metol (a developing agent) is common, but as far as I know it’s a skin reaction, not a problem with fumes. — Michael A.

Does anybody have any information about asthma and bronchitis being caused by exposure to any levels of photo chemical fumes, especially through innadequate ventilation (poor general instead of proper general or local ventilation)? I was feeling fine with no significant health problems until I started working in an in-house graphic arts photo lab at a big company in North Carolina in early 1992. Prior to starting that job, I was last sick with respiratory problems in 1987, and before that in early 1984. I should point out that the ventilation in these darkrooms was poorly-designed general ventilation for office spaces (these darkrooms were converted from offices). The company says that the ventilation in my darkroom was professionally designed and exceeded all standards for darkroom air flow volume (but not for air quality – which was never tested). After I started working at this job in April 1992, I started having a heavy flow of mucus and coughing in the Summer of 1992, and then started to get sick (either with infections or with heavy coughing and going hoarse) every couple of months. After moving into a new building (which I presume had darkroom ventilation designed to modern standards) in early 1993, another co-worker had her lab ventilation system changed by the installation of an electrostatic air-scrubber, which did nothing to eliminate the smell of the fumes. My darkroom ventilation wasn’t touched at that time. After this co-workers had a miscarriage in early 1994, the company installed local ventilation in her darkroom but wouldn’t do the same for me because I wasn’t a woman and couldn’t get pregnant. After I thought there was a link to the chemical fumes in the Summer of 1994 (after reading the Rossol & Shaw book on dangers in the photographic workplace), I went to an allergist, who told me that my problems weren’t the results of allergies but were chronic most likely due to occupational exposure. After hearing this, I started wearing a respiratory mask. And after I threatened to make a complaint to OSHA, my employer promissed to fix the problem by installing local ventilation (without ever doing any air quality tests) within three months. After the three months went by with no work being done, I started to seek more medical help outside my company. I was fired in May 1995 and the company installed something that looked like a local ventilation system a few days after I was fired. They never used that darkroom again after installing the new ventilation system, and in June 1998 they tore out the old processors and the new ventilation system shortly after hearing that my lawyer and I wanted to inspect and photograph the premisis. Any help and/or information would be apprciated.

Sodium Sulfite is notorious for setting off asthma and bronchitis in people who are sensitive to it. Sulfite is used in both developers and fixing baths and also in color chemicals. Sulfites are also sometimes used as preservatives (anti-oxidents) in food, particularly in meat, dried fruit, and wine. It can cause very strong reactions in those sensitive to it. Sulfur dioxide gas is also evolved from some solutions, particularly some fixing baths. This can be very irrating and is a trigger for Asthma in many sufferers. There are "oderless" fixing baths which do not evolve this gas. Beyond that there are probably several other chemicals which may affect some people. Certainly some developing agents, particulary Metol and Hydroquinone are sensitizers. While the most frequent symptom is an exzema-like rash it could affect some people in other ways. Until a few years ago many color processes included Formaldahyde. The fumes from this can definitely cause resperatory problems. Current chemistry for the most part contains substitutes for it. BTW the Rossol & Shaw book has been criticized for having many innacuracies. A good MD specialist in alergies should be familiar with the hazards of photo chemicals. — Richard Knoppow Los Angeles, Ca.
