I'm not an expert, but I'd be happy to put you in touch with an expert. What is interesting is that we are giving a prize at our upcoming annual conference for what was considered the most useful article in our peer-reviewed journal, Paediatrics & Child Health , last year. It is actually on overexposure to loud noises. It doesn't necessarily deal with toys as much as with video games. If you would like, I would be happy to put you in touch with the author of that journal article as well as with any of our experts on environmental exposures in things like children's toys. But I'm not an expert.
