What we found out is that about one in five users disposes of the contact lenses by throwing them into the bathroom sink or in the toilet, lead author Rolf Halden, director of the university's Center for Environmental Health Engineering, said Monday at a news conference at a meeting of the American Chemical Society.The study was presented at the meeting but has not been published or peer-reviewed, which are considered a gold standard in medical and scientific research.After being flushed, the lenses float through the wastewater system to sewage treatment plants. Halden said the researchers tested 11 brands of contacts and found that they don't degrade during the treatment process but tear into smaller and smaller pieces.The fragments are heavier than water, so they settle into the treated sewage sludge, which is often spread on land. The lenses can then make their way into rivers, lakes and the ocean through runoff."It sounds like a very small problem, because the lenses themselves are tiny, but they come by the billions," Halden said. The study estimated that about 45 million people wear contact lenses in the US alone."What we find is that there are billions of lenses ending up in US wastewater every year. They contribute a load of at least 20,000 kilograms per year of contact lenses," Halden said. That's between 6 and 10 metric tons of lenses, according to the study.Study co-author Charlie Rolsky said contact lenses are different than short-use plastics like straws, plastic bags or styrofoam because they are so important to people who wear them."It is a very personal high-value plastic that people sort of take for granted and utilize every day of their lives," Rolsky said.Halden said people don't think of the lenses as plastic waste because they feel like fluid, almost like water. They even come in tiny packets of saline solution.But even people who describe themselves as environmentally conscious admitted flushing their lenses, he noted."We have created an almost immortal material. It does not go away. It does not biodegrade," Halden said.This is a good thing when it comes to contact lenses, because, he said, you don't want them to degrade in the user's eye, which could impair vision or become a breeding ground for bacteria.Contact lenses are a small part of the pollution problem, Rolsky said, but he hopes that the findings encourage people to think more about how to get rid of plastic waste."This might have been a different experiment had there been labeling on a lot of these boxes sort of specifying 'maybe dispose of these with solid waste and please avoid having them go down a drain'; maybe it would be a different story," he said.Contact wearers should throw their lenses in the trash or recycle them, the researchers advise. 2779
Washington, D.C., the Trump administration, has failed utterly to help us fix a very broken immigration system, said California Attorney General Xavier Becerra. "These actions take us nowhere." 193
Weigand said Emma was looking forward to a fun night with friends at homecoming, but while she was dancing, she began to struggle with her breathing. School officials called her parents and requested a rescue squad.A police officer watched as Emma walked to her car to grab her asthma inhaler, but as she returned to the building, the officer noticed the teen was in serious trouble. She never made it back inside."And they went to sit her down in a chair and that's when she stopped breathing," Weigand said.Weigand said her daughter was revived twice through CPR, and during her second day at the hospital, doctors told the family that the teen could have less than 12 hours to live."We asked everyone to pray and she's still here and she's still fighting," Weigand said.Weigand said Emma has dealt with asthma since she was a toddler, but the condition has always been manageable. She also has allergies to eggs and chicken, but the family has no idea if Emma came into contact with either of those foods on homecoming."This is very out of the blue," she said.At the Norton High School, there are signs of support for Emma inside the building and outside near athletic fields. "WE ROAR WITH EMMA" t-shirts will be sold at Friday night's home football game. The shirts are also being sold on-line. Proceeds will go to the family to help with medical expenses. 1361
Washington is currently one of the hardest-hit states by COIVD-19. At least 109 people have died in the Seattle area alone. In Michigan, 60 people have died, and there are nearly 3,000 confirmed cases across the state.Amid reports that the United States had reached 100,000 confirmed cases of the coronavirus — the most in the world — Trump was asked about his presidential guidelines on social distancing, which expire on Monday. He declined to say if he would reinstate the guidelines this weekend but said he would speak to the task force before making a decision. Trump was also asked about his decision to invoke the Defense Production Act to order GM to begin producing ventilators to address a nationwide shortage. When asked about his comments on Thursday night, casting doubt on whether governors actually needed the number of ventilators they were asking for, Trump said he thought many governor's estimates were high, and he hoped he could provide and surplus ventilators to other countries. 1002
We are delighted that Centerplate donated the food we purchased making it available as a result of us terminating our convention early, the sorority's national president and CEO, Beverly Smith, said in a statement. "With 16,000 attendees and two food functions canceled -- our Sisterhood Luncheon and closing Soiree Celebration -- there was inordinate amounts of food that would have been wasted. Kudos to Centerplate." 419
