Microplastics in the environment are receiving a lot of interest but the ability to characterize them in environmental samples is still very limited. Compost is being widely used and encouraged for land applications, especially in urban areas. Little is known about the type and amount of different sizes of microplastic particles in compost materials. Compost could be the main contributor of microplastics into urban gardens, which often grow produces that can directly impact human health. BUEE students will work in the lab to isolate microplastic particles from compost samples collected in NYC and identify them using instrumental methods.
