p > this study was conducted in cooperation with researchers from Quest Diagnostics and Boston Children’s Hospital, and analyzed the unidentified data of more than 1.1 million blood tests. These blood tests were taken from children under the age of six from October 2018 to February 2020 and span all 50 states in the United States</ p>

p > surprisingly, 50.5% of the children tested had detectable blood lead levels equal to or higher than 1.0 µ g / dl, and 1.9% had blood lead levels equal to or higher than 5.0 µ g / dl. A previous study investigated the increase of blood lead levels in children from 2009 to 2015 and found that 3% of children had blood lead levels equal to or higher than 5.0 µ g / dl</ p>

<

p > it is reported that this is the first large-scale investigation to track blood lead levels below 5.0 µ g / dl. Although recent concerns have traditionally focused on blood lead levels above 5.0 µ g / dl, the Centers for Disease Control and Prevention (CDC) and the World Health Organization (who) have indicated that there is no safe lead exposure threshold, and any level of lead in children’s blood may lead to adverse effects</ p>

p > “given the lack of a threshold for the harmful effects of lead in children and that the effects of poisoning are basically permanent, prevention is extremely important,” said Jeffrey gudin, co-author of the study. “This means limiting exposure to and testing for lead in young children’s blood – if the results show a potential unsafe level, let them retest regularly.” </ P >

<

p > the study also shows that the lead exposure of American children will vary greatly depending on demographics and geographical location. Nebraska, Missouri, Michigan, Iowa and Utah all found detectable blood lead levels in more than 70% of the children sampled</ p>

<

p > in addition, compared with the children living in the areas with most houses after the 1950s, the blood lead level of children living in the areas with most houses before the 1950s was significantly higher. This confirms that many lead exposures are caused by old houses with lead pipes and paint</ p>

<

p > an editorial published with the new study by Philip Landrigan and David Bellinger called children’s lead exposure “a silent epidemic”. They called on the government to do more to eliminate the sources of lead exposure and pointed out that the higher blood lead levels found in African Americans and low-income communities reflected the “significant differences” still existing in the United States</ p>

<

p > Landrigan and Bellinger wrote: “These findings confirm that we still have a long way to go to end children’s lead poisoning in the United States. They reconfirm that there are unacceptable differences in children’s lead exposure in terms of race, nationality, income and Region – many of which are the cruel legacy of structural racism for decades – which falls most severely on the children and families with the least resources in our society.” </ P >

<

p > lead poisoning expert Morri Markowitz from Montefiore children’s Hospital said that children’s blood lead levels may have decreased significantly in the past 50 years, but the target needs to be zero because there is no safe lead exposure level. </ P >

<

p > Markowitz told Bloomberg: “There is lead in the environment, and it continues to exist. The situation is much better than 50 years ago, because how much lead is there, but it still exists.” </ P >
