Enviromental Impact On Hearing.. Is Anyone Listening ?
http://ehp.niehs.nih.gov/docs/1994/102-11/focus2.htmlMercury . Mercury intoxication causes hearing loss in humans and animals. In 1953, a severe neurological disorder was recognized among persons living in the vicinity of Minimata, Japan, where mercury-containing effluent flowing from a chemical manufacturing plant into the local bay contaminated shellfish. Deterioration in hearing and deafness were reported among other neurological symptoms. Findings consistent with Minimata disease have been reported in other instances of accidental mercury intoxication in Japan and Iraq. Early stages of poisoning may result in cochlear lesions, whereas hearing loss in the late stages of intoxication may result from neurological damage
Raelynn Janssen -Neuro-transmitters like glutamate may figure in hearing loss.
Lawrence Fechter, director of the toxicology department of Oklahoma University's College of Pharmacy and School of Medicine, says that studies on glutamate excitotoxicity have implications beyond auditory dysfunction. "I'm more and more convinced that what we're doing in the ear is very much like what is occurring in other parts of the nervous system. If you get excessive release of glutamate from presynaptic nerve endings, this can greatly elevate the level of calcium in the cells postsynaptic to it and produce a cascade of injurious effects. This 'extra-overstimulation,' if you will, or excitotoxic action, has been identified as one of the themes in neurotoxicity. People are talking about it in respect to learning, memory, Alzheimer's disease, and to other neurotoxic diseases."
Recently, Janssen demonstrated the blocking of glutamate cochlear neurotoxicity in rats through the use of glutamate receptor antagonists kynurenic acid and MK-801. Fechter is now also experimenting with MK-801. He says trimethyltin, an ototoxic and neurotoxic heavy metal, seems to work through a glutamatergic mechanism. "We've demonstrated we can protect against trimethyltin ototoxicity with MK-801," says Fechter. "We're now trying to develop candidate drugs which may be effective in preventing or reversing ototoxicity. People have been working in piecemeal fashion, identifying one chemical agent after another which is ototoxic. What's just beginning to emerge is some sense of fundamental mechanisms contributing to hearing loss which would allow us to more effectively predict new ototoxic agents and may also give us the wherewithal to protect the inner ear from injury."

http://www.lead.org.au/fs/fst7.htmlhttp://www.emedicine.com/radio/topic386.htmHeavy metals, such as lead and mercury, cause damage to the nervous system, which manifests differently in children and adults. Other toxins, both endogenous and exogenous, usually affect the nervous system with no age dependence.
The toxic affects of heavy metals on the CNS are well known. Several metals have toxic effects on the neurons and neurobehavior. Toxicity can be expressed either as developmental effects or as an increased risk of neurodegenerative diseases in old age. The major metals causing neurobehavioral effects after developmental exposure are lead and methyl mercury.
