TLDR
The presence of MPs in the livers of commercial zooplanktivorous fishes collected in the field is investigated and two translocation pathways are hypothesized: (i) large particles found in the liver resulted from the agglomeration of smaller pieces, and/or they simply pass through the intestinal barrier.About:

Investigating microplastics bioaccumulation and biomagnification in seafood from the Persian Gulf: a threat to human health?
TL;DR: The results of the trophic magnification factor (TMF) and biomagnification factor (BMF) calculation indicated that MPs were not biomagnified in edible parts of the marine food web of the Persian Gulf, contrary to previous belief.

A comparative review of microplastics and nanoplastics: Toxicity hazards on digestive, reproductive and nervous system
Kai Yin,Yu Wang,Hongjing Zhao,Dongxu Wang,Menghao Guo,Mengyao Mu,Yachen Liu,Xiaopan Nie,Baoying Li,Jingyan Li,Mingwei Xing +10 more
TL;DR: This review provided the latest research information on the differences in toxicity between MPs and NPs in the digestive system, reproductive system and nervous system, and explored the possible reasons for differences for the first time.

Toxicological effects of nano- and micro-polystyrene plastics on red tilapia: Are larger plastic particles more harmless?
Jiannan Ding,Huang Yejing,Shujiao Liu,Shanshan Zhang,Hua Zou,Zhenyu Wang,Wenbin Zhu,Jinju Geng +7 more
TL;DR: The results suggest that the toxicity of N/MPs may not show a simply monotonic negative correlation with their sizes, and the activity of CYP3A-related enzyme was obviously inhibited by PS-NPs, whereas the CYP enzymes in the liver may not be sensitive to MP exposures.

A Review of Human Exposure to Microplastics and Insights Into Microplastics as Obesogens
TL;DR: Evidence is accumulating that feeding bottles and medical devices can contribute to MP exposure in newborns and infants and there is evidence to support the hypothesis that MPs and their additives are potential obesogens.

Effects of bisphenol A and nanoscale and microscale polystyrene plastic exposure on particle uptake and toxicity in human Caco-2 cells
Qiangqiang Wang,Bai Jialei,Baoan Ning,Longxing Fan,Tieqiang Sun,Yanjun Fang,Jin Wu,Shuang Li,Chenhui Duan,Yingchun Zhang,Jun Liang,Zhixian Gao +11 more
TL;DR: MTT experiments confirmed that microplastics caused an increase in cytotoxicity, which may be related to increased cellular oxidative stress and mitochondrial depolarization, and reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) assays.

Journal ArticleDOI
Accumulation and fragmentation of plastic debris in global environments.
TL;DR: Global plastics production and the accumulation of plastic waste are documented, showing that trends in mega- and macro-plastic accumulation rates are no longer uniformly increasing and that the average size of plastic particles in the environment seems to be decreasing.

TL;DR: Using data from the Malaspina 2010 circumnavigation, regional surveys, and previously published reports, this work shows a worldwide distribution of plastic on the surface of the open ocean, mostly accumulating in the convergence zones of each of the five subtropical gyres with comparable density.

Microplastic Ingestion by Zooplankton
Matthew Cole,P. Lindeque,Elaine S. Fileman,Claudia Halsband,Rhys M. Goodhead,Julian Moger,Tamara S. Galloway +6 more
TL;DR: It is shown that microplastics are ingested by, and may impact upon, zooplankton, and imply that marine microplastic debris can negatively impact upon zoopLankton function and health.

Ingested Microscopic Plastic Translocates to the Circulatory System of the Mussel,Mytilus edulis(L.)
Mark Anthony Browne,Awantha Dissanayake,Tamara S. Galloway,David M. Lowe,Richard C. Thompson +4 more
TL;DR: The data indicate as plastic fragments into smaller particles, the potential for accumulation in the tissues of an organism increases and further work using a wider range of organisms, polymers, and periods of exposure will be required to establish the biological consequences of this debris.

Occurrence of microplastics in the gastrointestinal tract of pelagic and demersal fish from the English Channel.
TL;DR: Microplastic ingestion appears to be common, in relatively small quantities, across a range of fish species irrespective of feeding habitat, and further work is needed to establish the potential consequences.
