  • From macroplastic to microplastic: Degradation of high‐density polyethylene, polypropylene, and polystyrene in a salt marsh habitat

    As part of the degradation process, it is believed that most plastic debris becomes brittle over time, fragmenting into progressively smaller particles. The smallest of these particles, known as microplastics, have been receiving increased attention because of the hazards they present to wildlife. To understand the process of plastic degradation in an intertidal salt marsh habitat, strips ...

  • Green Water Infrastructure

    Stormwater runoff is a major cause of water pollution in urban areas. When rain falls on roofs, streets, and parking lots, the water cannot soak into the ground. In most urban areas, stormwater is drained through engineered collection systems and discharged into nearby waterbodies. The stormwater carries trash, bacteria, heavy metals, and other pollutants from the urban landscape, degrading the ...
