Effects of micro- and nanoplastics on non-biting midges (Chironomus spp.): protocol for a systematic review and multilevel meta-analysis

AI summary Read the abstract

This document outlines a planned project, not finished results. It describes a plan to collect and combine existing laboratory and tank-based studies on how tiny plastic particles affect non-biting midge insects (Chironomus species), looking at how different doses and particle types relate to effects.

Study Type Review

Systematic review and multilevel meta-analysis of controlled laboratory and mesocosm studies testing the effects of micro- and nanoplastics on Chironomus spp., with dose–response, particle-property moderators and a comparison of dose metrics. Full protocol attached (v1.3).

Evaluation of the hazard of irregularly-shaped co-polyamide microplastics on the freshwater non-biting midge Chironomus riparius through its life cycle

AI summary Read the abstract

Laboratory experiments exposed the freshwater midge Chironomus riparius to irregularly shaped co-polyamide microplastics across its full life cycle, finding effects on survival, development, and reproduction at environmentally relevant concentrations. The study highlights that real-world plastic shapes and polymers, not just the smooth spheres commonly used in tests, can harm freshwater invertebrates.

Combined effects of microplastics and a pyrethroid on the benthic invertebrate, Chironomus Riparius

AI summary Read the abstract

This freshwater study examined combined effects of microplastics and a pyrethroid pesticide on midge larvae (Chironomus riparius), contributing to growing evidence that microplastics in freshwater ecosystems interact with chemical pollutants to produce compounded harmful effects on invertebrates.

Multigenerational effects of polyethylene microplastics on freshwater benthic invertebrates, Chironomus tepperi

AI summary Read the abstract

Researchers exposed the freshwater benthic midge Chironomus tepperi to polyethylene microplastics (8-20 µm) in sediment at four environmentally relevant concentrations over two generations, finding no significant effects on growth but significant decreases in survival and emergence rates at the highest concentration (1,000 MPs/kg) in both generations. Metabolic analyses were conducted to further characterize sublethal mechanisms of MP toxicity in this common stormwater sediment organism.

The effects of nano- and microplastic ingestion on the survivorship and reproduction of Aedes aegypti and Aedes albopictus (Diptera: Culicidae)

AI summary Read the abstract

Researchers studied how nano- and microplastic ingestion affects survivorship and reproduction in small invertebrates, finding that exposure reduced reproductive output and survival rates in a dose-dependent manner. The results suggest that even environmentally relevant concentrations of plastic particles can impair fitness in aquatic invertebrates.

Mechanisms influencing the impact of microplastics on freshwater benthic invertebrates: Uptake dynamics and adverse effects on Chironomus riparius

AI summary Read the abstract

Researchers studied the factors influencing microplastic uptake and toxicity in the freshwater midge Chironomus riparius using experimental data and agent-based modeling. They found that high concentrations of small microplastics fill the insect gut, are eliminated more slowly than natural particles, and cause damage to gut tissue that leads to reduced growth and delayed development. The study suggests that microplastic concentrations in some freshwater hotspots may already be high enough to cause adverse effects in wild populations.
