Plastics are a group of materials that are mass produced for their unique properties including durability. This has led to plastics becoming a global contaminant as a bulk material and as micro and nano sized particles termed microplastics and nanoplastics (MP/NPs), respectively. As awareness to MP/NPs has grown, these contaminants are found to be ubiquitous yet the risk to environmental systems remained unclear. Toxicity studies have been performed but the transport, fate, and behavior of these contaminants remains limited by the selectivity and sensitivity of the commonly used analytical techniques. To address this deficiency, MP/NP tracers have been developed using …

Microplastics have become ubiquitous in the environment and have been intensively studied in recent years. Researchers have documented several toxic effects to aquatic organisms, but the role of different microplastic properties in the toxic responses is not well understood. Toxic effects can be altered by the microplastic pieces themselves, by chemicals from the microplastics, and by sorbed environmental organic or metal pollutants, which microplastics concentrate and transport. I decided to focus on the chemical aspect of microplastic toxicity by observing responses of a marine invertebrate when exposed to several types of leachate solutions, created by soaking microplastics in seawater for …
