There is some monitoring going on now, though it is far from comprehensive. Right to Know gets its information from a copy of EPA's TRIS database. I got into it and listed hydrogen fluoride emissions, by company and amount, for the state of Oregon, as well as Clark County and Longview, Washington. In southern Washington we get local hydrogen fluoride emissions from Reynolds Metals Co. in Longview, and from Vanalco Inc. and SEH-America, Inc. in Vancouver. In Oregon, several companies release fluoride emissions.
People today get fluoride from other sources as well.
We get it in much of our foods, which are grown or processed with fluoridated water. We get high doses in both black tea and green tea. We get it in certain medications, including some major anti-depressants. We get it in the air as industrial emissions. And we get it in dental products and treatments.
