I almost always enjoy hearing from visitors to the Eco-USA web site. (Alas, there have been a couple of exceptions over the last dozen years.) Send me an e-mail at habeck (dot) mike (at) gmail (dot) com.
While I wish you every success in your endeavors, I'm afraid I don't have any job openings, don't buy or sell chemicals, have no money to give out, or the time to help with homework questions. I also cannot provide medical or legal advice, including determining whether past or future exposures to particular substances have resulted or will manifest themselves in specific medical conditions. Please see a physician or an attorney for medical or legal advice.
If you're writing about something else, I may take quite awhile to respond - other duties call. Apologies in advance for that.
