Designers have developed a mineral-coated sand that can saturate up harmful steels such as lead and cadmium from sprinkle. Seperti Apakah Ciri Ciri Ayam Bangkok Aduan Super
Together with its ability to ruin natural contaminants such as bisphenol A, this material could help cities take advantage of stormwater, an plentiful but underused sprinkle resource.
Scientists understood that the normally occurring minerals they covered into sand could respond with natural pollutants such as chemicals in stormwater. However, the ability of the covered sand to also remove hazardous steels throughout filtering could open metropolitan sprinkle supplies that had been crossed out.
Cities with Mediterranean environments, such as Los Angeles, could store stormwater below ground throughout damp winter seasons, where it could function as an affordable, local provide throughout the dry period. But this source has gone mainly untapped because stormwater picks up harmful chemicals as it runs through roads and rain seamless gutters.
"IT MAKES SENSE THAT WE FIGHT BACK WITH A TREATMENT TECHNOLOGY THAT HAS THESE IMPRESSIVE DOUBLE ABILITIES TO TAKE OUT BOTH TOXIC METALS AND ORGANICS."
"The contaminants that keep back the potential of this sprinkle resource seldom come one by one," says lead writer Joe Charbonnet, that conducted this research as a finish trainee in civil and ecological design at the College of California, Berkeley.
"It makes good sense that we resist with a therapy technology that has these outstanding double capcapacities to get both harmful steels and organics. We thought that the mineral-coated sand was unique, but the way it proceeds to thrill us with several abilities is instead remarkable."Cities often dispose of stormwater as pollution because it picks up contamination such as lead bits left from years of leaded gas emissions or chemicals from yards. Direct exposure to these chemicals is associated with slow neurological development in children and some kinds of cancer cells. However, scientists say that their covered sand material could be installed in rainfall yards in position such as parking area where stormwater can be gathered and cleaned.
