Abstract

Abstract

Marine microplastics pollution is an emerging marine environmental issue and has attracted worldwide attention. Due to the special geographical environment characteristics, the coastal bays become the hotspot for microplastics distribution research. Here we report data on the abundance and characteristics of microplastics collected from surface seawater of the Jinzhou Bay. Samples were collected from 11 sites by horizontal trawling of a plankton net in October 2017. Wet peroxide oxidation process and micro Fourier-transform infrared absorption spectroscopy were conducted to remove the organic material mixed in the sample and identified the composition of microplastics. The research results showed that the average abundance of microplastics in the Jinzhou Bay was (0.93±0.59) items/m³, and accounting for 96.2% of the total plastic debris. Polypropylene and polyethylene were the main components of microplastics, accounting for 55.0% and 23.5%, respectively. The main types of microplastics were lines and fragments, accounting for 41.7% and 26.2%, respectively. White, blue and translucent was the most common color, accounting for 35.1%, 26.0% and 21.4%, respectively. Affected by hydrodynamic conditions and riverine input, the spatial distribution of microplastics in the surface seawater of the Jinzhou Bay was higher in the north areas than that in the south.
