“…For example, low-density materials such as PE are more likely to float and disperse more widely in surface waters than high-density materials such as polyvinyl chloride 7 . Moreover, naturally-derived and semi-synthetic items are less likely to persist in the marine environment than synthetic items 26,60 , although in tropical environments with high UV-radiation the deterioration rate of synthetic items may be significantly increased 61 . Indeed, once in the marine environment both chemical and physical characteristics are affected by abiotic (e.g.…”

Marine microdebris, in particular microplastics (plastics <5 mm), has become an issue of international concern due to its prevalence, persistence and potential adverse impacts on marine ecosystems. Informing source reduction based on ecological effects requires an understanding of the origin, distribution and characteristics of microdebris and the interactions with marine organisms. Here we show widespread contamination of the central Great Barrier Reef environment with microdebris, with microfibres comprising 86% of all items detected. Microdebris intake by coral reef fish was non-random, with chemical composition, shape and colour differing significantly from that detected in surface waters. Furthermore, the origin of microdebris contamination in surface waters is non-random with riverine discharge a likely source for microdebris detected at inshore, but not at offshore reef locations. Our findings demonstrate the complexities associated with determining marine microdebris exposure and fate, and assist in improving future ecological assessments and prioritizing source reduction.

“…The emissions and leaks of large shipping are considered as an important source of microplastics [ 64 ]. Loss and damage of fishing and aquaculture equipment can easily introduce plastic particles into the ocean [ 9 , 65 , 66 ]. Followed by marine aquaculture, the main offshore source is the world’s fishing fleet [ 67 ], garbage illegally discarded from ships or offshore platforms [ 68 ], and a large proportion of items comes from lost containers [ 56 , 69 ].…”

The serious global microplastic pollution has attracted public concern in recent years. Microplastics are widely distributed in various environments and their pollution is already ubiquitous in the ocean system, which contributes to exponential concern in the past decade and different research areas. Due to their tiny size coupled with the various microbial communities in aquatic habitats capable of accumulating organic pollutants, abundant literature is available for assessing the negative impact of MPs on the physiology of marine organisms and eventually on the human health. This study summarizes the current literature on MPs in the marine environment to obtain a better knowledge about MP contamination. This review contains three sections: (1) sources and fates of MPs in the marine environment, (2) impacts of MPs on marine organisms, and (3) bacteria for the degradation of marine MPs. Some measures and efforts must be taken to solve the environmental problems caused by microplastics. The knowledge in this review will provide background information for marine microplastics studies and management strategies in future.

“…It is estimated that there were approximately 4.7 million fishing vessels globally in 2012 (Moffitt and Cajas-Cano, 2014). Sometimes, lost, abandoned, worn-out of fishing and aquaculture gears (including PE netting and twine) (Al-Oufi et al, 2004; Thomas and Hridayanathan, 2006), and other equipment during use can easily result in the introduction of microplastic particles, which continue to entangle or kill marine life and damages habitats, ultimately impacting fish stocks and quality. Besides, operational and accidental spills by large shipping vessels and cargo are also regarded as the significant source of resin pellets despite the fact that monitoring data for these are sparse.…”

A critical review on the sources and instruments of marine microplastics and prospects on the relevant management in China

The world's oceans are suffering a constant and unprecedented accumulation of emerging plastic contaminants known as microplastics with a particle diameter smaller than 5mm. Microplastics exhibit a widespread distribution in various habitats from land to the oceans, and even reach the most remote regions - the deep sea and the polar, receiving attention exponentially in the past few years. Owing to their small size, marine species risk getting ingested and entangled in microplastics, causing suffocation, starvation, physical trauma or damage from chemicals, which poses vast and growing threats to biodiversity and the food web. This review article focuses on the various sources attributed to marine microplastics, the latest international, regional and national countermeasures to combat marine litter, as well as the status quo of microplastics pollution, legislation and regulations in China, and furthermore provides improving proposals/solutions on key research gaps, governance and management for future environmental control and policymaking in China.
