A new study by a graduate student in the University of Toronto’s Faculty of Applied Science & Engineering measured significant concentrations of traffic-related air pollution near roadways in the small island nation of Trinidad and Tobago, reaching levels comparable to highways in major urban centres like Toronto and Detroit.
Chelsea Rochman, assistant professor of ecology and evolutionary biology at the University of Toronto, says we should be paying close attention to what’s taking place closer to home in the Great Lakes.
“The contamination in the Great Lakes and other bodies of freshwater from plastics and microplastics is ubiquitous,” says Rochman, who looks at plastic debris and its associated chemical contaminants.
