1 00:00:05,00 --> 00:00:07,00 We encounter hundreds of chemicals every day: 2 00:00:08,00 --> 00:00:11,00 in our food, the air, water, soil, dust, and 3 00:00:12,00 --> 00:00:15,00 the products we use. 4 00:00:15,00 --> 00:00:17,00 While many chemicals are considered harmless, 5 00:00:17,00 --> 00:00:19,00 some may be harmful to our health. 6 00:00:19,00 --> 00:00:22,00 星空娱乐官网鈥檚 Environmental Health Laboratory studies the chemicals in 7 00:00:22,00 --> 00:00:26,00 our environment to help us find out which ones may be harmful. 8 00:00:27,00 --> 00:00:30,00 For more than 30 years, 星空娱乐官网 scientists have tracked 9 00:00:30,00 --> 00:00:33,00 what chemicals people are exposed to and how much 10 00:00:33,00 --> 00:00:35,00 of those chemicals get into their bodies. 11 00:00:35,00 --> 00:00:38,00 This type of scientific study is called biomonitoring. 12 00:00:39,00 --> 00:00:42,00 The information we learn from biomonitoring helps scientists 13 00:00:42,00 --> 00:00:46,00 plan and conduct research about the chemicals in our environment, 14 00:00:46,00 --> 00:00:48,00 and how those chemicals might affect our health. 15 00:00:48,00 --> 00:00:50,00 And public health officials use biomonitoring results 15 00:00:50,00 --> 00:00:54,00 to make important decisions, like developing better policies, 16 00:00:54,00 --> 00:00:57,00 programs, and guidelines to protect our health. 17 00:00:58,00 --> 00:01:03,00 Biomonitoring also helps us assess the nutrition status of the U.S. population. 18 00:01:03,00 --> 00:01:06,00 Through biomonitoring, we can find out if Americans are getting 19 00:01:06,00 --> 00:01:10,00 too little, too much, or the right amount of key nutrients. 20 00:01:11,00 --> 00:01:14,00 Today, the Biomonitoring Program can reliably measure more than 21 00:01:14,00 --> 00:01:18,00 300 chemicals and nearly 60 nutrition indicators in people. 22 00:01:18,00 --> 00:01:21,00 Our scientists use methods that can measure even 23 00:01:20,00 --> 00:01:23,00 very low levels of these chemicals in small amounts of 24 00:01:23,00 --> 00:01:26,00 people鈥檚 blood and urine. 25 00:01:27,00 --> 00:01:30,00 The Biomonitoring Program works together with several other organizations, 26 00:01:30,00 --> 00:01:33,00 including state and local health departments. 27 00:01:34,00 --> 00:01:37,00 If there鈥檚 an environmental emergency in your state, 28 00:01:37,00 --> 00:01:40,00 like a chemical spill, the Biomonitoring Program can provide 29 00:01:40,00 --> 00:01:44,00 important data to your state鈥檚 health department to help state officials understand 30 00:01:44,00 --> 00:01:47,00 who may have been exposed to harmful substances. 31 00:01:48,00 --> 00:01:51,00 In addition to helping in emergency situations, 32 00:01:51,00 --> 00:01:54,00 the Biomonitoring Program works with other researchers 33 00:01:54,00 --> 00:01:59,00 and state health departments to conduct 60 to 70 exposure studies each year. 34 00:01:59,00 --> 00:02:03,00 These studies help us learn about the chemicals in a specific area or community and 35 00:02:03,00 --> 00:02:06,00 how they might affect residents鈥� health. 36 00:02:07,00 --> 00:02:11,00 星空娱乐官网鈥檚 Biomonitoring Program also provides funding and support for state public health 37 00:02:11,00 --> 00:02:13,00 laboratories to do their own research through the 38 00:02:13,00 --> 00:02:16,00 State Biomonitoring Cooperative Agreement. 39 00:02:16,00 --> 00:02:18,00 States can use the funding to train laboratory staff, 40 00:02:18,00 --> 00:02:23,00 provide technical support, and conduct site visits to the laboratories. 41 00:02:24,00 --> 00:02:28,00 And finally, the Biomonitoring Program is a part of the National Biomonitoring Network, 42 00:02:28,00 --> 00:02:34,00 a network of regional, state, and local labs dedicated to high-quality biomonitoring research.
