How microplastics are making their way into our farmland
October 6, 2023
Microplastic pollution is a global environmental problem that is ubiquitous in all environments, including air, water and soil. Microplastics are readily found in treated wastewater sludge, also known as municipal biosolids, that eventually make their way to our agricultural soils. Our recent investigation of microplastic levels in Canadian municipal biosolids found that a single gram of biosolids contains hundreds of microplastic particles. This is a much greater concentration of microplastics than is typically found in air, water or soil.
