Toxic Effects of Long-Term Exposure to Mercury Vapor

Long-term loss of color vision after exposure to mercury vapor.

We evaluated the color vision of 24 subjects (41.6 +/- 6.5 years; 6 females) who worked in fluorescent lamp industries. They had been occupationally exposed to mercury vapor (10.6 +/- 5.2 years) and had been away from the source of exposure for 6.4 +/- 4.04 years. Mean urinary concentration of mercury was 40.6 +/- 36.4 microg/g creatinine during or up to 1 year after exposure and 2.71 +/- 1.19 ...

Color-space distortions following long-term occupational exposure to mercury vapor.

Color vision was examined in subjects with long-term occupational exposure to mercury (Hg) vapor. The color vision impairment was assessed by employing a quantitative measure of distortion of individual and group perceptual color spaces. Hg subjects (n = 18; 42.1 ± 6.5 years old; exposure time = 10.4 ± 5.0 years; time away from the exposure source = 6.8 ± 4.6 years) and controls (n = 18; 46.1 ±...

HEALTH - Toxic Exposure: Mercury

It can be found in countless modern-day products, from thermometers and fluorescent light bulbs to dental fillings. Unfortunately, this unique metal is toxic to humans, and exposure can lead to neurological damage, com...
