Ecotoxicity of Emerging Contaminants in Aquatic Birds: What We Know?

AI summary Read the abstract

Researchers examine how aquatic birds are disproportionately exposed to emerging contaminants including microplastics, reviewing ecotoxicological evidence of physiological and reproductive harm in avian species and highlighting their potential role as sentinel indicators of ecosystem-wide pollution.

As emerging contaminants increasingly infiltrate aquatic ecosystems, aquatic birds are facing heightened risks due to exposure to a wide range of pollutants. This chapter provides a comprehensive examination of the ecotoxicological effects of microplastics,...

Effects of Emerging Contaminants on Wildlife

AI summary Read the abstract

This review documents how newly introduced contaminants such as microplastics, pesticides, personal care products, and pharmaceuticals harm wildlife across multiple species and ecosystems. Even low concentrations of these pollutants can disrupt animal reproduction, development, and survival, signaling broader ecological risks that extend up the food chain to humans.

Microplastic Contamination in Aquatic Organisms: An Ecotoxicological Perspective

AI summary Read the abstract

"This ecotoxicological review examined how microplastics accumulate in aquatic organisms across multiple trophic levels, documenting impacts on physiology, reproduction, and behavior, as well as the transport of associated chemical contaminants through food webs. Because humans sit at the top of aquatic food chains, the bioaccumulation dynamics described here translate directly into dietary microplastic exposure, making ecotoxicological endpoints in fish and shellfish key indicators of human health risk."

Analytical Challenges in the Ecotoxicology of Emerging Environmental Pollutants

AI summary Read the abstract

Microplastics have been identified as one of the most significant emerging environmental pollutants alongside pharmaceuticals, requiring new ecotoxicological frameworks to assess their combined effects on ecosystems. The analytical complexity of detecting and characterizing microplastics in environmental and biological samples continues to hinder accurate risk assessments.

Why Study the Ecotoxicity of Contaminants of Emerging Concern?

AI summary Read the abstract

Researchers examined a broad class of pollutants — contaminants of emerging concern — including microplastics, pharmaceuticals, and nanomaterials that standard environmental regulations largely overlook. Understanding their ecotoxicity matters because these substances are increasingly detected in drinking water, food, and human tissue with largely unknown long-term consequences.
