1. Short title This Act may be cited as the Comprehensive National Mercury Monitoring Act . 2. Findings Congress finds that— (1) mercury is a potent neurotoxin of significant ecological and public health concern; (2) it is estimated that approximately 200,000 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) based on estimates from the Centers for Disease Control and Prevention, between 2000 and 2010, between 2 and 6 percent of women in the United States of childbearing age have exceeded blood mercury levels determined to be safe by the Environmental Protection Agency; (4) exposure to mercury occurs largely by the consumption of contaminated fish, but fish and shellfish are important sources of dietary protein and micronutrients, 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) existing broad-scale data sets are important but insufficient to track changes in mercury levels in the environment over time, test model predictions, and assess the impact of changing mercury emissions and deposition
