Researchers investigated how chemical pollution affects wildlife behavior, arguing that conventional study approaches are insufficient and calling for new frontiers in quantifying behavioral responses to contaminants in free-living animal populations.
Investigating the Behavioral Implications of Microplastic Exposure in Animal Species
This review analyzed 110 papers on the behavioral consequences of microplastic exposure across a range of animal species including plankton, fish, amphibians, crustaceans, pollinators, and mammals. Researchers found that microplastics disrupt feeding, metabolism, reproduction, and neurological function, with fish showing the most significant behavioral impacts and mice exhibiting the most severe physiological damage. The study emphasizes that these behavioral changes can alter ecological niches and reduce animal survival.
Neurophysiological and Behavioral Effects of Micro- and Nanoplastics in Aquatic Organisms
Researchers reviewed evidence that micro- and nanoplastics in aquatic environments cross the blood-brain barrier, accumulate in neural tissues, and cause oxidative stress, neuroinflammation, and disrupted neurotransmitter signaling, with downstream effects on locomotion, feeding, predator avoidance, and social behavior across multiple aquatic species.
Neurobiology and changing ecosystems: Toward understanding the impact of anthropogenic influences on neurons and circuits
This review examines how rapid anthropogenic environmental changes -- including habitat contamination, degradation, and climate change -- affect neurobiological systems in animals, focusing on cellular and biophysical mechanisms of neurons and circuits. The authors discuss how nervous systems evolved over millions of years to detect and respond to environmental change and assess whether the unprecedented pace of current anthropogenic changes may exceed animals' adaptive neurobiological capacity.
Neurotoxicity in Marine Invertebrates: An Update
This review updates the current understanding of neurotoxicity caused by environmental pollutants, including microplastics, in marine invertebrates. Researchers summarize evidence showing that contaminants can disrupt neurotransmitter systems, impair behavioral responses, and cause oxidative damage to nervous tissue in species like mollusks and crustaceans. The study highlights the importance of marine invertebrates as bioindicators for assessing the neurological impacts of emerging pollutants in ocean ecosystems.
Animal exposure to microplastics and health effects: A review
Researchers reviewed how microplastic exposure affects animals across terrestrial and aquatic environments, finding that species suffer physical harm, chemical contamination from pollutants that stick to plastic surfaces, inflammation, and behavioral changes. Because microplastics accumulate up the food chain, the review warns that animals entering the human food supply may carry these particles into our bodies.
Ecological disturbances and abundance of anthropogenic pollutants in the aquatic ecosystem: Critical review of impact assessment on the aquatic animals.
This critical review assessed the ecological disturbances caused by anthropogenic pollutants including microplastics in aquatic ecosystems, examining uptake, accumulation, and biological effects across invertebrate and vertebrate species, and identifying gaps in understanding of long-term ecotoxicological impacts at environmentally relevant concentrations.
From environment to brain: the role of microplastics in neurobehavioral disorders
This review examines how microplastics enter the human body and cross the blood-brain barrier, linking their presence in neural tissue to neurobehavioral disorders through mechanisms including neuroinflammation, oxidative stress, and disruption of neurotransmitter systems.
Neurotoxicity of microplastic particles in the human brain: a systematic review
This systematic review examines how microplastic particles may affect the human brain and nervous system. The research found that microplastics can reach the brain and cause changes in behavior and thinking, though more studies are needed to understand the long-term effects. This is an early but important signal that plastic pollution could impact brain health.
Plastics and their derivatives are impacting animal ecophysiology: A review
This review examines how microplastics interact with marine life through ingestion, entanglement, and chemical leaching, disrupting organisms from plankton to large fish. The paper highlights that plastic pollution in the ocean directly connects to human health through the food chain, as contaminated seafood transfers microplastics and their toxic additives to people who eat it.
The effects of micro- and nanoplastics on the central nervous system: A new threat to humanity?
This review summarizes growing evidence that micro- and nanoplastics can cross the blood-brain barrier and damage the central nervous system through inflammation, oxidative stress, and disruption of brain chemicals. The authors note that microplastic exposure has been linked to memory and behavior changes in animals and may contribute to neurodegenerative diseases like Parkinson's, though direct human evidence is still limited.
Nanoplastics and biota behaviour: Known effects, environmental relevance, and research needs
This review examined how nanoplastics affect the behavior of aquatic and terrestrial organisms, finding that behavioral endpoints are sensitive indicators of nanoplastic exposure but highlighting the need for more environmentally relevant concentrations and chronic exposure studies.
Effects of environmental pollution on wildlife and human Health and novel mitigation strategies
This review examines how environmental pollution from urbanization, industrialization, and chemical misuse affects both wildlife and human health across multiple ecosystems. The study discusses novel mitigation strategies for addressing contamination issues including chemical residues in animal-derived foods and the rising frequency of environment-related toxicity.
Assessing the Impact of Microplastics on Brain Chemistry: The Need for a Comprehensive Policy Framework to Mitigate Toxicity
This review examines the growing evidence that microplastics can cross biological barriers, accumulate in brain tissue, and affect neurological function. Researchers found that microplastic exposure has been linked to neurotoxicity, oxidative stress, and inflammation in the brain, with potential implications for neurotransmitter systems and cognitive function. The study calls for comprehensive regulatory measures to limit microplastic pollution and further research into the long-term neurological health effects.
Pesticide exposure and the microbiota-gut-brain axis
This review examines how pesticide exposure can disrupt gut bacteria and, through the gut-brain connection, potentially affect behavior and brain health. Animal studies show that pesticides change the makeup of gut microbes in ways linked to anxiety, depression, and other neurological effects. While focused on pesticides rather than microplastics, the research highlights how environmental chemicals can harm health through the gut.
A review of the neurobehavioural, physiological, and reproductive toxicity of microplastics in fishes
This review summarizes how microplastics cause a range of harmful effects in fish, including behavioral changes, brain and immune system damage, oxidative stress, and reproductive disruption through interference with hormone signaling. These findings are relevant to human health because many of the same biological pathways affected in fish also exist in humans, and people consume fish that have accumulated microplastics.
Current Advances in Aquatic and Marine Toxicology
This review paper summarizes current research on how pollution affects water environments and the animals living in them. Scientists are finding that new types of pollution like microplastics, medicines in water, and tiny manufactured particles are creating health risks that we don't fully understand yet. This matters because these pollutants can end up in our drinking water and the fish we eat, potentially affecting human health.
Toxicological implications of emerging pollutants on aquatic organisms
Researchers reviewed how a broad range of emerging pollutants — including microplastics, pharmaceuticals, pesticides, and heavy metals — harm aquatic organisms like fish, amphibians, and molluscs. Evidence shows these pollutants trigger oxidative stress, disrupt hormones, impair reproduction, and reduce biodiversity, with the review calling for stronger regulations, better wastewater treatment, and more research on the combined effects of multiple pollutants.
