TL;DR: Wang et al. as discussed by the authors investigated the vertical distribution of bacterial community structure in two eutrophic lakes of China, Lake Taihu and Lake Xuanwu, using a molecular fingerprinting technique, denaturing gradient gel electrophoresis (DGGE) followed by DNA sequence analysis, and the results were interpreted with multivariate statistical analysis.

TL;DR: The discovery of the chronic neurotoxin BMAA in a large limnic ecosystem together with possible pathways of accumulation within major food webs deserves serious consideration due to its potential long-term risk to human health.

TL;DR: This article investigated the adsorption properties of heavy metals onto polystyrene (PS) microplastics as well as the bioavailability and toxicity of microplastic and heavy metals by hydroponic wheat seedlings experiment.

TL;DR: Exposing the freshwater cyanobacterium Microcystis aeruginosa to different sizes (1 μm and 100 nm) of polystyrene microplastics of 5 mg/L shows that smaller size does not necessarily mean greater toxicity, improving understanding of the toxicity of microplastic pollution in freshwater ecosystems, and challenging the conventionally held belief that smallermicroplastics are more toxic.

TL;DR: The results suggest that phosphorus transference occurs between M. aeruginosa and its attached Pseudomonas in microenvironment may be important to microfood web and cyanobacteria bloom.
