Section 2: Biomonitoring helps to shape policies that affect our health

so biomonitoring commits scientists important information about the substances we’re exposed to and how they affect our torsoes that datum helps our government and public health officials make more informed decisions shown is an image of a trailer that predicts cdc national health and nutrition evaluation inspect cdc imparts a sketch every two years to assess the health and nutritional status of adults and children in the u.s it’s called the national health and nutrition investigation overlook or nhanes for short scientists at the biomonitoring program use the nhanes overlook ensues to gather exposure data or information about the levels of compounds in people’s people here’s how “whos working” firstly scientists opt a test a small group of people who participated in the nhanes survey to analyze to reflect our diverse population here in the united states scientists make sure to include parties of different age groups genders and ethnicities then they study blood and urine samples from this group of people to be informed about what chemicals and how much of those chemicals are in their bodies shown is a webpage featuring the cdc’s national report on human exposure to environmental compounds finally cdc publishes the results in a report called the national report on human exposure to environmental chemicals and updated counters this report is the most comprehensive assessment ever made of human exposure to environmental compounds shown is the cover of the cdc’s fourth national report on human exposure to environmental chemicals 2019 the first form of the report published in march 2001 included showing data relating to 27 compounds added reports followed in 2003 2005 and 2009 together with several report updates those reports and inform included show data relating to more substances the most recent version includes showing data for more than 300 chemicals and includes findings from 1999 to 2016. Here are a few of the chemicals included in the report they include guide pesticides and phthalates all that biomonitoring data has led to important policy changes that protect our nation’s health for example biomonitoring research played an important role in reducing lead use in the united states people who are exposed to high levels of lead can get lead poison which may cause learning disabilities and behavior problems very high levels of lead in the body can cause convulsions coma or even extinction shown is an image of a mansion that reads for utilization as motor fuel exclusively contains induce tetraethyl in 1981 the u.s environmental protection agency or epa was considering changing the law to allow more lead in gasoline but thanks in large proportion to biomonitoring research the epa decided to restrict the use of leaded gasoline instead here’s how it happened the epa’s research be anticipated that leaded gasoline would have a limited impact on blood lead tiers or the amount of precede beings have in their bodies but a cdc investigation showed that blood pass positions had plunged from 1976 to 1980 and that the plummet tracked abridged implement of guide and gasoline over that time period decreased expend of produce and gasoline resulted from the introduction of unleaded gasoline in the united states more experiment presented similar the relations between result and gasoline and blood guide levels in other countries based on this critical technical prove the epa decided to restrict the use of leaded gasoline and as remaining extend was removed from gasoline blood lead stages continued to decline removing conduct from decorate has also made a big impact on lead elevations in the u.s by 1999 blood pas degrees in children senilities 1 to 5 had fallen to historic lows but we haven’t altogether solved the lead problem while lead-based paint was banned from use in housing in 1978 as countless as 24 million older homes still have result colour or conduct contaminated dust and about 4 million of those are home to young children who are most likely to be affected by extend poisoning show is the cover of the cdc’s fourth national report on human exposure to environmental substances 2019 so biomonitoring scientists continue to track lead stages in americans helping us assess how well national programs aimed at reducing or eliminating extend exposure are working more information about blood lead ranks is available in cdc’s national report on human exposure to environmental chemicals and updated counters biomonitoring has also helped us introduced policies in place to reduce people’s exposure to secondhand smoke nicotine is the addictive chemical used in tobacco produces like cigarettes vaping inventions and grinding tobacco even people who don’t inhale or use other tobacco produces might be exposed to nicotine when they spend time in places where other parties are inhaling this is called secondhand smoke and it can be harmful to people’s health codine is a substance that kinds in your body when you’re exposed to nicotine by measuring the levels of coding in a person’s body scientists “re going to tell” how much nicotine they’ve been exposed to cdc biomonitoring scientists developed a space to weigh very low levels of coding in people’s people they found that 88 of people who didn’t inhale were exposed to second-hand smoke and people who worked around tobacco had even higher levels of codeine in their bodies this data inspired new laws to restrict smoking in public houses when cdc valued codeine levels again in 1999 and 2000 they found that average coding elevations among beings senilities 3 and older had decreased by more than 70 percentage that conveys beings were exposed to a lot less second-hand smoke the 2006 surgeon general’s report celebrated this dramatic reduction shown is a graphic named trends and exposure of non-smokers to secondhand smoke in the u.s population national health and nutrition scrutiny investigation 1988 -2 002 perkel atal 2006 however there is still more work to be done children’s coding grades are still twice those of both adults and new tobacco produces like e-cigarettes and vape pencils could also present serious health risks shown is the cover of the cdc’s fourth national report on human exposure to environmental compounds 2019 biomonitoring scientists continue to track coding grades to assess how well efforts to reduce secondhand smoke exposure are working for more information on coding elevations experience cdc’s national report on human exposure to environmental chemicals and revised tables
