RETRACTED: Environmental fate of aquatic pollutants and their mitigation by phycoremediation for the clean and sustainable environment: A review
AI summary Read the abstract
This retracted review covered how algae-based remediation could help clean up water pollutants including microplastics, pharmaceuticals, and pesticides. It discussed how nanomaterials and microplastics interfere with marine ecosystems and can harm both aquatic life and humans. Note: this paper has been retracted, so its findings should be treated with caution.
Emerging pollutants such as natural and manufactured chemicals, insecticides, pesticides, surfactants, and other biological agents such as personal care products, cosmetics, pharmaceuticals, and many industrial discharges hamper the aquatic environment. Nanomaterials and microplastics, among the categories of pollutants, can directly interfere with the marine ecosystem and translate into deleterious effects for humans and animals. They are either uncontrolled or poorly governed. Due to their known or suspected effects on human and environmental health, some chemicals are currently causing concern. The aquatic ecology is at risk from these toxins, which have spread worldwide. This review assesses the prevalence of emerging and hazardous pollutants that have effects on aquatic ecosystems and contaminated water bodies and their toxicity to non-target organisms. Microalgae are found to be a suitable source to remediate the above-mentioned risks. Microalgae based mitigation techniques are currently emerging approaches for all such contaminants, including the other categories that are discussed above. These studies describe the mechanism of phycoremediation, provide outrage factors that may significantly affect the efficiency of contaminants removal, and discuss the future directions and challenges of microalgal mediated remediations.

Research advances on impacts micro/nanoplastics and their carried pollutants on algae in aquatic ecosystems: A review
AI summary Read the abstract
This review examines how micro- and nanoplastics harm algae, which are the foundation of aquatic food chains, by slowing growth, reducing photosynthesis, and damaging cells. The effects are worse when microplastics carry other pollutants on their surfaces, creating a combined toxic effect. Since algae support the entire aquatic food web, damage to these organisms can ripple upward through fish and shellfish to affect the safety of seafood consumed by humans.
Sustainable Algal Nanomaterials for Microplastics and Lanthanide Remediation
AI summary Read the abstract
Scientists are exploring how algae can be used to create tiny, eco-friendly particles (called nanoparticles) that soak up pollutants like microplastics and certain metals from water and soil. This review paper summarizes existing research on how these algae-based particles are made and how well they clean up environmental contaminants, offering a greener alternative to chemical-based cleanup methods. Since microplastics and heavy metals can end up in our food and water, finding sustainable ways to remove them could help reduce our long-term exposure to these harmful substances.
Microalgal Bioremediation of Microplastics: Current Advances, Challenges and Environmental Applications
AI summary Read the abstract
Tiny plastic particles called microplastics are everywhere in our water and food, and they're small enough to slip into our cells and tissues, raising health concerns. This review paper looks at how microscopic algae might help clean up the problem—by trapping plastic particles, sticking to them and sinking them out of the water, or even breaking them down using natural enzymes. While this is still an emerging area of research rather than a ready-to-use solution, it points to a promising, eco-friendly way to reduce the amount of plastic pollution that ends up in our water, food, and ultimately our bodies.
Microplastic contaminants in the aqueous environment, fate, toxicity consequences, and remediation strategies
AI summary Read the abstract
This review covers the sources, fate, and toxic effects of microplastic contaminants in aquatic environments, along with current remediation strategies for removing them. Researchers found that microplastics cause various health problems in aquatic organisms and can enter the human food chain through contaminated seafood and water. The study emphasizes the urgent need for improved waste management and novel cleanup technologies to address microplastic pollution in water systems.
