Excess rains and poor wastewater management are key factors that contribute to the presence of microplastics in urban lakes.
A recent study highlights the major pathways through which microplastics enter city lakes, including continuous rainfall, stormwater runoff, wastewater treatment plants, littering zones, and laundry facilities.
The amount of plastics entering freshwater systems is forecast to increase from an estimated range of 9-14 million tons in 2016 to approximately 23-37 million tons by 2040.
According to a United Nations Environment Programme (UNEP) report, microplastics contamination of freshwater systems is a pressing problem that requires attention.
