Correction to Quantitative Analysis of Selected Plastics in High-Commercial-Value Australian Seafood by Pyrolysis Gas Chromatography Mass Spectrometry
Summary
This paper corrects an error in a previously published study on plastic mass concentrations in high-commercial-value Australian seafood, revising the sardine figure from 0.3 to 2.9 mg per gram of tissue. The correction also clarifies that oysters are suspension feeders, not deposit feeders, and that microplastics are captured in the gills or ingested through the mouth rather than from sediments.
In the abstract, it is stated that “Sardines contained the highest total plastic mass concentration (0.3 mg gtissue) and squid the lowest (0.04 mg gtissue). The correct statement is “Sardines contained the highest total plastic mass concentration (2.9 mg gtissue) and squid the lowest (0.04 mg gtissue).” In section 3.3.3. Pacific oysters (C. gigas), the text reads “Oysters are deposit feeders, which means that they filter particulate matter (including microplastics) from the water and sediments. The particles are first taken up through the inhalant siphon from the surrounding water and trapped in the gills, which is the first contact organ. In the gills, the particulate matter transfers to the haemolymph that goes to the heart and from there it is distributed to the rest of the body because of oyster’s open circulatory system.” We would like it to be corrected to “Oysters are suspension feeders,1 which means that they can capture particulate matter (including microplastics) from the water. The particles can be trapped in the gills or ingested through the mouth.”.
