Which of the following statements about the research is CORRECT? [br]
(7)A study has found elevated levels of caffeine in the Pacific waters off the Oregon coast, but it doesn’t appear that the region’s many cafes and coffeehouses are to blame. Researchers from Portland State University and Washington State University, Vancouver, looked at caffeine pollution off the coast as part of a broader study of contaminants in the water. Their findings are published in the Marine Pollution Bulletin.
After taking samples from 21 spots along the coast, researchers expected to find the most caffeine pollution in areas near wastewater treatment plants, large population centers or rivers and streams emptying into the o-cean, said Elise Granek, assistant professor of Environmental Science and Management at Portland State. She conducted the study with her former graduate student, Zoe Rodriguez del Rey, and Steve Sylvester of Washington State.(8)Instead, they found high caffeine levels near Carl Washburne State Park and Cape Lookout, two areas not near the potential pollution sources, and low levels of caffeine near large population centers such as Astoria, Warrenton and Coos Bay. They also found high levels of caffeine after a late-season storm that triggered sewer overflows.
选项
