Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a University of Otago study showing they are still harmful to fish.
Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a University of Otago study showing they are still harmful to fish.
Petroleum-derived microplastics are known to impact marine life, but little is known about the impact of biodegradable alternatives.
The study, published in Science of the Total Environment and funded by a University of Otago Research Grant, is the first to assess the impact petroleum-derived plastic and biodegradable plastic have on wild fish.
Lead author Ashleigh Hawke, who completed a Master of Science in Otago’s Department of Marine Science, says petroleum-derived plastic exposure negatively affected the fishes escape performance, routine swimming, and aerobic metabolism.
