OSU researchers find small particles from tires inhibit growth of organisms in freshwater, coastal estuaries

Green Car Congress

Small particles from tires inhibit the growth and cause adverse behavioral changes in organisms found in freshwater and coastal estuary ecosystems, according to two new Oregon State University studies. Both organisms had reduced growth depending on the level of exposure to micro tire particles. Credit: John Dickens.
