Krill Digesting Microplastic

Turning microplastics into nanoplastics through digestive fragmentation by Antarctic krill SUMMARY: This study found that krill were breaking down microplastic beads into smaller and smaller pieces in their digestive system. The krill were divided into two groups, one eating 80% plastic beads with 20% algae, the other eating 20% plastic beads and 80% algae. The… Continue reading Krill Digesting Microplastic

Review: Microplastics in Canadian Aquatic Ecosystems

Microplastics in aquatic environments: Implications for Canadian ecosystems SUMMARY: This article reviews currently research studies on microplastics. It talks about the sources of microplastics, the amount in aquatic systems, the effects on organisms, and finally the gaps in research. LESSON COMMENTS: While you can certainly read this article in its entirety, I would focus on… Continue reading Review: Microplastics in Canadian Aquatic Ecosystems

Effects of Antibiotics on Plankton

Interspecies Interactions Reverse the Hazard of Antibiotics Exposure: A Plankton Community Study on Responses to Ciprofloxacin hydrochloride SUMMARY: Antibiotics that have made their way into aquatic ecosystems may have an effect on the food chains there. This study tested the effects of ciprofloxacin hydrochloride on 2 different types of algae (phytoplankton) and a species of… Continue reading Effects of Antibiotics on Plankton

Feeding Plastic to Rotifers

Microplastic Size-Dependent Toxicity, Oxidative Stress Induction, and p-JNK and p-p38 in Activation in the Monogonont Rotifer (Brachionus koreanus)(NOT OPEN ACCESS) SUMMARY: Rotifers (Brachionus koreanus) were fed fluorescent microplastic beads of 3 different sizes: 6um, 0.5um, 0.05um. The pictures in this article show how much microplastic was still left inside the rotifers right after eating, after… Continue reading Feeding Plastic to Rotifers
