Quantifying the Impacts of Plastic Pollution on Animals: A Systematic Map of Meta-Analyses – PROTOCOL
AI summary Read the abstract
This study is creating a comprehensive map of existing research that examines how plastic pollution (including tiny microplastics) affects animals. The researchers are summarizing and organizing all the scientific studies that have already been done to identify what we know and what research is still missing. This matters because understanding how plastic pollution impacts animals can help us better understand potential risks to human health, since we're exposed to the same plastic particles through our food and environment.
This study aims to develop a systematic map of published meta-analyses that quantitatively assess the effects of plastic pollution on animals. With global plastic production constantly increasing, there has been also increase in research efforts on overall effects plastic pollution present in environment has on living organisms. While numerous primary studies and also syntheses like meta-analyses have examined the biological impacts of plastic exposure, there is currently no comprehensive overview of what has been synthesized, which taxa and environments have been covered, and where evidence gaps remain. Our systematic map will identify, catalogue, and classify existing meta-analyses addressing the physical, chemical, and behavioral effects of macro-, micro-, and nanoplastics on animals. In addition, bibliometric analysis will characterize research trends, geographic and institutional distributions, collaboration networks, and thematic structures within the body of synthesized literature.

Quantifying the Impacts of Plastic Pollution on Animals: A Systematic Map of Meta-Analyses – PROTOCOL
AI summary Read the abstract
Researchers developed a protocol for creating a systematic map of published meta-analyses that quantitatively assess the effects of plastic pollution on animals. The project aims to catalogue and classify existing evidence on the physical, chemical, and behavioral effects of macro-, micro-, and nanoplastics across different species and environments. The study seeks to identify gaps in the current body of synthesized research and highlight areas where further investigation is needed.
What is known and unknown about the effects of plastic pollution: A meta‐analysis and systematic review
AI summary Read the abstract
This meta-analysis and systematic review pools data from hundreds of studies to assess whether plastic pollution, both large pieces and microplastics, poses a real ecological threat. The findings confirm negative effects on wildlife across many species and environments, underscoring that plastic pollution is not just an aesthetic problem but a genuine risk to ecosystems and the food chains humans rely on.
Beyond harm: synthesising meta-analytical and mechanistic evidence on animal responses to microplastics
AI summary Read the abstract
This review pulls together results from 14 existing studies to get a bigger-picture view of how microplastics affect animals, looking at things like growth, reproduction, and behavior across many species. The takeaway: microplastics generally cause measurable harm to animals, though the severity varies depending on the species and the type of biological function being studied. Since these animals often share biology with humans and sit in our food chain (think fish and shellfish), this kind of harm is an early warning sign worth paying attention to, even though it doesn't directly prove the same effects happen in people.
“Reproductive and Transgenerational Toxicity of Micro- and Nanoplastics: A Systematic Review and Meta-Analysis”
AI summary Read the abstract
This meta-analysis pools data from multiple animal studies to assess how micro- and nanoplastics affect reproduction and the health of future generations. The research looks at whether plastic particle exposure can harm fertility, pregnancy outcomes, and offspring development in lab animals. These findings are important because they suggest microplastic exposure could have effects that extend beyond the individual to their children.
Beyond harm: synthesising meta-analytical and mechanistic evidence on animal responses to microplastics
AI summary Read the abstract
This review pulls together findings from 14 previous studies to look at how microplastics affect animals overall, things like their growth, behavior, and survival. The takeaway is that microplastics generally cause measurable harm across many species, which raises concern since these tiny plastic particles are already found in our food, water, and even our bodies. While this study focuses on animals rather than humans directly, it adds to growing evidence that microplastic pollution is a biological stressor worth taking seriously.
