Researchers propose that increased levels of man-made chemicals in marine plankton might be used to monitor the influence of human activities on ecosystem health and perhaps explore linkages between ocean pollution and land-based rates of childhood and adult chronic disease.
Nearly century-old studies of microscopic marine plankton and the rise of man-made chemicals found in the ocean could be used to measure the impact of human activity on ecosystem health as well as study chronic illnesses in people, according to a study by researchers at UC San Diego in La Jolla.
Using samples from an almost century-old, ongoing survey of marine plankton, researchers at University of California San Diego School of Medicine suggest that rising levels of manmade chemicals found in parts of the world's oceans might be used to monitor the impact of human activity on ecosystem health, and may one day be used to study the connections between ocean pollution and land-based rates of childhood and adult chronic illnesses.
