TL;DR: The results showed that the dominant contaminants (polypropylene fibers and polyethylene fibers) might originate from the abrasion of fishing gear and contributed to 61.6% of the total abundance of microplastics in surface sediment.

TL;DR: The authors in this paper reviewed both the recent and longer-term (Holocene) ecological history of coral reefs in the South China Sea (SCS) and showed that the coral reefs of the SCS have declined dramatically, reflecting the rapid decrease of living coral cover and the great loss of symbiotic zooxanthellae.

TL;DR: Compared to those from other typical mangrove wetlands of the world, the metal levels in Hainan were at low- to median-levels, which is consistent with the fact that Hainen Island is still in low exploitation and its mangroves suffer little impact from human activities.

TL;DR: According to the acceptable daily intakes (ADIs) and maximum residue limits (MRLs) proposed by different organisations, these aquatic products (shrimp, crab and oyster) reached the standard of safe consumption and could not pose a health risk to human, however, a potential elevated risk to humans may remain.

TL;DR: In this paper, the coarse fraction of enclosed lagoon sediments is used as a proxy for past strong storms/tsunamis in the southern South China Sea, based on the principle that coarse fractions are usually controlled by strong sedimentary dynamics on the surrounding reef flat, and thus increases in the weight percentages of coarse-grained fractions of the lagoon sediment should also reflect strong storm or tsunami events.
