Environmental processes and ecological effects of microplastics in the ocean
Summary
This Chinese review examines the environmental processes and ecological effects of microplastics in ocean environments, covering how plastics degrade, distribute, and interact with marine organisms. It discusses both physical and chemical toxicity mechanisms and the potential for microplastics to transfer up the food chain.
There are no doubts that plastics problem in the ocean environment has become an increasingly worldwide focus in past several decades. A number of experts regard the plastic wastes as one of the hardest anthropogenic threats. The degraded items of large individual plastics lead to millions of microplstics (MPs) ultimately. As a result, the new pollution has appeared in the ocean. The ever-growing MPs have been detected in subtotal sea products, such as sea food and table salts. The MPs can bring potential health risk to people by enrichment in sea products. Furthermore, the economic development of offshore fishery and the marine tourism have been inhibited badly. This article will make a brief review on present studies about MPs in the ocean.
