Continuous rainfall and poor wastewater management are major contributors to the presence of microplastics in urban lakes, according to a recent study.
Weather conditions, especially continuous rainfall, drive microplastics into city lakes. Other significant pathways include stormwater runoff, wastewater treatment plants, littering zones, and laundry facilities.
A study on Dal lake in Srinagar examined the routes that microplastics take to enter urban lakes. The data suggests that microplastics contamination of freshwater systems is a pressing problem, with the amount of plastics entering these systems forecast to increase from 9-14 million tons in 2016 to 23-37 million tons by 2040, according to a United Nations Environment Programme (UNEP) report.
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.
Author's summary: Excess rains and poor management contribute to microplastics in city lakes.
