Responses Of The Symbiotic Sea Anemone Anthopleura Elegantissima To Microplastics, Robert Beck
Responses Of The Symbiotic Sea Anemone Anthopleura Elegantissima To Microplastics, Robert Beck
WWU Graduate School Collection
The Salish Sea, a large and complex fjord estuary, receives waters impacted by a watershed that includes 8 million people aggregated in several large urban and industrial centers. Microplastics, defined as plastic particles less than 5 mm in their largest dimension, are transported from this watershed into the Salish Sea where they are easily ingested by filter feeders, herbivores and predators. To measure effects of microplastics on one common and important intertidal species, we exposed the sea anemone Anthopleura elegantissima to polyester microfibers at concentrations of 0, 0.01, or 0.1 g/L in the laboratory and measured the responses of the …
Ecological Risk Assessment Of Tire Wear Particles In The San Francisco Bay Using A Bayesian Network Relative Risk Model, Emma E. Sharpe
Ecological Risk Assessment Of Tire Wear Particles In The San Francisco Bay Using A Bayesian Network Relative Risk Model, Emma E. Sharpe
WWU Graduate School Collection
Here we present an ecological risk assessment for a specific type of microplastic in the San Francisco Bay. There has been an increased interest in understanding and managing the impacts that microplastics may have on ecological systems because recent studies have shown that plastic particles are widespread in the environment and that exposure to these particles has toxicological effects. Until now, an ecological risk assessment for microplastics that meets the current standards for risk assessment, has not been completed. This study lays the groundwork for future ecological risk assessments of microplastics and identifies key uncertainties that need to be addressed. …
