B/W Photo Processing Dangerous or Harmful with Pregnancy?
Hello,
My wife and I recently found out she is pregnant. We're worried something may have happened to our baby because she has been going to school developing photos in a B/W lab. Here's the gist of what happened: We've traced the conception date to 10/14. We found out today, which is 10/29. Her last visit to the dark room was on the 24th, ~9 or 10 days after conception. Within those ~10 days, she went to the dark room 4 times spending a total of ~8 hours in it. She did not use gloves and touched the solution with her bare fingers. Quickly after touching the solution, she washed her hands with water, no soap was used. Before the conception date, she's spent the last 6 weeks in the dark room, maybe once or twice a week. I already know how stupid we are for doing what we did, so please do not lecture me on that. I would really like to know if we did any harm to the baby and if there is anything we can do now besides pray. Thank you for your help. -Jason |

I'm not sure most ob/gyn's would know the toxicity of common photo
chemicals. Probably better to call the manufacturer of the chemical and ask what the constituents of each solution (developer, fixer, etc.) are if there is no list of ingredients on the label. Then do a Google search on the individual chemicals; this will turn up at least one or more websites where toxicity descriptions of various chemicals are located. Many of those descriptions will say whether the chemical can be absorbed through the skin and the degree of toxicity incurred. My guess (and it's only a guess) is that, depending on what chemicals your wife was using, she was probably more at risk from fumes than from touching the solutions. Most darkroom chemicals are fairly harmless, though there are some that are definitely toxic. That's why you're right not to take the risk of not knowing. But it is important to identify the specific chemicals so you can get accurate information. Bob Salomon wrote: In article , (Jason) wrote: Hello, My wife and I recently found out she is pregnant.

Unless she was selenium toning with skin contact or bathing her hands in developer for prolonged periods, it's unlikely you've done any harm. There are many professions for which the practitioners pay with shortened lifespans -- chemists, for instance, have a high incidence of cancer and organ failures due to solvents used in their work, as do painters and auto body workers. Photographers have show no such effect, even those who spend literally decades in daily darkroom work. There are some people who become sensitized to certain chemicals -- metol, aka Elon, is one, various aldehydes used in non-metal gelatin hardeners are another (glutaraldehyde is the most common, but it's used mainly in X-ray processing to protect emulsion at very high process temperatures needed for rapid results). Pyrogallol is toxic, but not significantly more so than many other chemicals we use regularly, including permanent hair dyes. Color developers, bleach, and especially stabilizer are others for which skin contact should be avoided. Of these, AFAIK only pyrogallol and metol are known to have significant skin contact risks, and pyrogallol is rarely if ever used in instruction for photography; most likely the developer she was using for printing was Dektol or similar containing metol and hydroquinone. If she doesn't have a relatively immediate reaction, she's not sensitive, and it's my understanding metol isn't signifcantly absorbed through the skin. Developers also typically contains a good bit of sodium sulfite as a preservative and silver solvent. Stop bath isn't anything to worry about -- acetic acid, same as vinegar; if you have a variety without indicator dye, you could drink it without harm. Fixer has sodium thiosulfate or ammonium thiosulfate, sodium sulfite as a preservative (sodium sulfite is also used as a food additive), sodium metabisulfite (another food additive), and acetic acid (vinegar again). Sodium thiosulfate is the specific antidote for cyanide poisoning; it isn't a recommended dietary supplement, but isn't significantly toxic. The biggest hazard from fixer is sulfur dioxide evolved from a reaction of the thiosulfate with acid, and this is in very low concentrations. Used developer and fixer both contained dissolved silver compounds and complexes, but these aren't normally a skin absorption hazard. Overall, I'd be surprised if there were a problem -- there's a much bigger risk if she had a few glasses of wine or beer in the last couple weeks before learning of the conception, IMO. Disclaimer: I'm neither a toxicity expert nor a physician -- everything I've said here should be checked with someone who is qualified to verify it. Chemical names you'll want besides those above are phenidone, dimezone, pyrocatechin, and p-aminophenol hydrochloride, benzotriazole, potassium iodide, sodium perborate, sodium metaborate, sodium carbonate, possibly sodium hydroxide if using Rodinal (these last four alkali activators for developers), tetrasodium EDTA, Calgon, and similar sequestrants and chelators. To give some idea how harmless a developer *can* be, you can develop film in coffee with sodium carbonate added... -- The challenge to the photographer is to command the medium, to use whatever current equipment and technology furthers his creative objectives, without sacrificing the ability to make his own decisions. -- Ansel Adams Donald Qualls, aka The Silent Observer http://silent1.home.netcom.com Opinions expressed are my own -- take them for what they're worth and don't expect them to be perfect. |

om... Hello, My wife and I recently found out she is pregnant. We're worried something may have happened to our baby because she has been going to school developing photos in a B/W lab. The most likely consequence of this case will be the baby's exposure will be to his/her father's alarmist presumptions. You are advised to consult a professional, not Usenet (for God's sake) for answers, and possible treatment for your anxiety lest you infect the child. |

While I don't think most B&W chemistry is harmful I think it's best to avoid drinking it or coming into direct contact with it. I still remember when working on cars and lawnmowers we used to wash our hands with leaded gasoline. In jr. high school we used asbestos gloves and boards when dealing with alcohol lamps. If the OP is concerned he may want to go to Kodak's website and download the MSDSs of the chemistry his wife came into contact with. -- Keep working millions on welfare depend on you ------------------- |
