Polluting Your Brain: Science Deniers Say Mercury's Just Dandy

Famed science deniers Willie Soon and Paul Driessen, both of whom have worked for groups that accept cash from Exxon Mobil to pretend global warming isn't happening, have a new crusade: Mercury denial!

That's right: They have an op-ed in Wednesday's Wall Street Journal claiming that breathing toxic mercury isn't bad for you.

Willie Soon, astronomer. And Paul Driessen, lobbyist with a degree in geology. Expertise in public health? Limited. Willingness to take cash from the coal polluters that pump tons of mercury into our air every year? Extensive.

What's that? You want to know what actual medical researchers have to say about the subject? Fine, have it your way:

For fetuses, infants, and children, the primary health effect of methylmercury is impaired neurological development. Methylmercury exposure in the womb, which can result from a mother's consumption of fish and shellfish that contain methylmercury, can adversely affect a baby's growing brain and nervous system. Impacts on cognitive thinking, memory, attention, language, and fine motor and visual spatial skills have been seen in children exposed to methylmercury in the womb. Recent human biological monitoring by the Centers for Disease Control and Prevention in 1999 and 2000 shows that most people have blood mercury levels below a level associated with possible health effects. More recent data from the CDC support this general finding.

Outbreaks of methylmercury poisonings have made it clear that adults, children, and developing fetuses are at risk from ingestion exposure to methylmercury. During these poisoning outbreaks some mothers with no symptoms of nervous system damage gave birth to infants with severe disabilities, it became clear that the developing nervous system of the fetus may be more vulnerable to methylmercury than is the adult nervous system. [...]

In addition to the subtle impairments noted above, symptoms of methylmercury poisoning may include; impairment of the peripheral vision; disturbances in sensations ("pins and needles" feelings, usually in the hands, feet, and around the mouth); lack of coordination of movements; impairment of speech, hearing, walking; and muscle weakness.

The Environmental Protection Agency is acting right now to limit mercury pollution. Please take a moment to tell the EPA you support its efforts.
