SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Comprehensive National Mercury 
Monitoring Act''.

SEC. 2. FINDINGS.

    Congress finds that--
            (1) mercury is a potent neurotoxin of significant 
        ecological and public health concern;
            (2) it is estimated that approximately 410,000 children 
        born each year in the United States are exposed to levels of 
        mercury in the womb that are high enough to impair neurological 
        development;
            (3) the Centers for Disease Control and Prevention have 
        found that 6 percent of women in the United States of 
        childbearing age have blood mercury levels in excess of values 
        determined to be safe by the Environmental Protection Agency;
            (4) exposure to mercury occurs largely by consumption of 
        contaminated fish, but fish and shellfish are important sources 
        of dietary protein, and a healthy fishing resource is important 
        to the economy of the United States;
            (5) in many locations, the primary route for mercury input 
        to aquatic ecosystems is atmospheric emissions, transport, and 
        deposition;
            (6) computer models and other assessment tools provide 
        varying effectiveness in predicting mercury concentrations in 
        fish, and broad-scale data sets are insufficient to test model 
        predictions; and
            (7) a comprehensive national mercury monitoring network to 
        accurately quantify regional and national changes in 
        atmospheric deposition, ecosystem contamination, and 
        bioaccumulation of mercury in fish and wildlife in response to 
        changes in mercury emissions would help policy makers, 
        scientists, and the public to better understand the sources, 
        consequences, and trends in United States mercury pollution.
