原文
As an Alaskan fisherman, Timothy June, 54, used to think that he was safe from industrial pollutants at his home in Haines—a town with a population of 2,400 people and 4,000 eagles, with 8 million acres of protected wildland nearby. But in early 2021, June agreed to take part in a ______ of 35 Americans from seven states. It was a biomonitoring project, in which people’s blood and urine were tested for ______ of chemicals—in this case, three potentially dangerous classes of compounds found in common household ______ like face cream, tin cans, and shower curtains. The results, ______ in November in a report called “Is It in Us?” by an environmental group, were rather worrying. Everyone of the participants, ______ from an Illinois state senator to a Massachusetts minister, tested positive for all three classes of pollutants. And while the ______ presence of these chemicals does not necessarily indicate a health risk, the fact that typical Americans carry these chemicals at all ______ June and his fellow participants. Clearly, there are chemicals in our bodies that don’t belong there.
Ongoing studies conducted by the Centers for Disease Control and Prevention have found 148 chemicals in Americans of all ages. And in 2021, the Environmental Working Group found an ______ of 200 chemicals in the blood of 10 newborns. “Our babies are being born pre-polluted,” says Sharyle Patton of Commonweal, which cosponsored “Is It in Us?” “This is going to be the next big environmental issue after climate change.”
