Effects of microplastic and heavy metals on coral reefs: A new window for analytical research
AI summary Read the abstract
This review explores how microplastics and heavy metals together threaten coral reef ecosystems, which are vital to coastal communities worldwide. Researchers describe how these pollutants accumulate on coral surfaces through sedimentation and adsorption, potentially disrupting reef health and biodiversity. The study calls for new analytical approaches to better understand the combined impacts of these two major categories of marine pollution on coral reefs.
In the modern world, plastic trash has been recognized as a global issue, and studies on microplastics (MPs) in the marine and inland environments have previously been conducted. Marine ecosystems act as a bio-diverse ecosystem where coral reefs contribute to make a sound living of the coastal people by gathering natural resources. The current study indicates that MPs and heavy metals (HMs) accumulation to biofilm and organic matter through sedimentation, precipitation, adsorption, and desorption that may have potential effect on growth and development of coral reefs in the marine ecosystems. However, the knowledge of distribution, impact, mechanism, degradation, and association mechanisms between MPs and HMs in the natural environment may open a new window for conducting analytical research from an ecological viewpoint. The current study thus summarizes the types of marine samples with the analytical techniques, polymers of MPs, and their impact on corals and other marine biota. This study also identifies existing knowledge gaps and recommends fresh lines of inquiry in light of recent developments in MPs and HMs research on the marine ecosystems. Overall, the present study suggests a sustainable intervention for reducing MPs and HMs from the marine ecosystems by demonstrating their existence in water, sediment, fish, corals, and other biota, and their impending ecotoxicological impacts on the environment and human health. The impacts of MPs and HMs on coral reefs are critically assessed in this study in light of the most recent scientific knowledge, existing laws, and new suggestions to minimize their contamination in the marine ecosystems.

Microplastic as an invisible threat to the coral reefs: Sources, toxicity mechanisms, policy intervention, and the way forward
AI summary Read the abstract
This review examines how microplastics threaten coral reefs by causing physical damage, chemical toxicity, and disruption to coral biology. Microplastics can block coral feeding, carry harmful chemicals, and promote disease-causing bacteria on coral surfaces. While focused on coral ecosystems, the findings matter for human health because healthy reefs support fisheries and coastal communities that millions of people depend on.

The Unseen Threat of the Synergistic Effects of Microplastics and Heavy Metals in Aquatic Environments: A Critical Review
AI summary Read the abstract
This review examines how microplastics and heavy metals interact in water environments, finding that microplastics can attract and concentrate toxic metals on their surfaces through various chemical forces. This combination effect is a concern for human health because contaminated microplastics carrying heavy metals can be consumed through seafood, delivering a double dose of pollutants.
Macro- and microplastics as complex threats to coral reef ecosystems
AI summary Read the abstract
This review summarizes the growing threat that plastic pollution, from large debris down to nanoplastics, poses to coral reef ecosystems worldwide. Researchers found that microplastics can impair coral feeding, skeletal formation, and nutrition, weakening reef health. The study calls for including plastic monitoring in reef conservation programs and promoting a circular economy to reduce plastic waste entering oceans.
A systematic review of microplastics in coral reef ecosystems: Abundance, distribution, toxicity, and future research directions
AI summary Read the abstract
This systematic review examined 125 studies on microplastic pollution in coral reef ecosystems. Corals are ingesting microplastics, which can cause tissue damage, stress responses, and impaired growth. Since coral reefs support roughly 25% of all marine species and many fisheries that feed coastal communities, their contamination with microplastics has far-reaching consequences for ocean health and food security.
