Everyone is exposed to mercury
Concentration in fish tissue and amount of fish eaten is a major component of man’s exposure
Mercury in air is not at levels where breathing it might cause adverse health effects
The public health report showed that 82-99% of exposure to mercury is from eating fish.

The concentration of mercury in fish and the amount of fish eaten are major components of man’s exposure to mercury.

Mercury in air is not at levels where breathing it might cause adverse health effects.

Mercury exposure near a significant source of mercury emissions also showed that breathing mercury in air is not at levels where breathing it might cause adverse health effects.

The amount of mercury in the air becomes important in the methylation and bioaccumulation processes resulting in mercury accumulation in fish tissue.

Even though everyone is exposed to mercury, the amount of exposure in terms of milligrams of mercury per body weight per day is the important factor to determine if adverse health effects might occur.
