The widespread introduction of plastics in the 1950s has led to a significant environmental contamination widely impacting land (i.e., soils) and sea (i.e., rivers, oceans). This problem is further aggravated by the breakdown of plastics into microplastics, which can persist in the environment threatening ecosystems and human health. Identifying potential sources of plastic contamination on land is crucial for implementing effective mitigation strategies. EMIT measurements can help pinpoint sources of plastic pollution that may contribute to ocean leakage or soil contamination.

Global Plastics Detection

Detection of Plastics Worldwide Using the EMIT Space-Based Observations

Plastic pollution has become a major environmental challenge, with most contamination starting on land before reaching oceans. EMIT imaging spectrometer helps track this pollution by identifying unique light signatures of plastics from space. For this project, EMIT detected two common plastics, HDPE and PVC, across multiple continents, often linked to agricultural activities. This work highlights the potential of satellite technology to monitor plastic pollution and support efforts to reduce its impact.
