currentsinbiology: Ban on microbeads offers best chance to protect oceans, aquatic species An outright ban on the common use of plastic “microbeads” from products that enter wastewater is the best way to protect water quality, wildlife, and resources used by people, a group of conservation scientists suggest in a new analysis. These microbeads are one part of the microplastic problem in oceans, freshwater lakes and rivers, but are a special concern because in many products they are literally designed to be flushed down the drain. And even at conservative estimates, the collective total of microbeads being produced today is enormous. In an article just published in the journal Environmental Science and Technology, scientists from seven institutions say that nontoxic and biodegradable alternatives exist for microbeads, which are used in hundreds of products as abrasive scrubbers, ranging from face washes to toothpaste. Around the size of a grain of sand, they can provide a gritty texture to products where that is needed. “We’re facing a plastic crisis and don’t even know it,” said Stephanie Green, the David H. Smith Conservation Research Fellow in the College of Science at Oregon State University, and co-author of this report. -- source link
