Human Health and Ocean Pollution
AI summary Read the abstract
This review examined the health impacts of ocean pollution, emphasizing that prevention of land-based pollution sources is key to protecting human health, and recommending bans on single-use plastics, persistent organic pollutants, and improved wastewater treatment. The paper advocates for Marine Protected Areas, renewable energy transitions, circular economy principles, and strong international marine pollution control programs.
World leaders who recognize the gravity of ocean pollution, acknowledge its growing dangers, engage civil society and the global public, and take bold, evidence-based action to stop pollution at source will be critical to preventing ocean pollution and safeguarding human health.Prevention of pollution from land-based sources is key. Eliminating coal combustion and banning all uses of mercury will reduce mercury pollution. Bans on single-use plastic and better management of plastic waste reduce plastic pollution. Bans on persistent organic pollutants (POPs) have reduced pollution by PCBs and DDT. Control of industrial discharges, treatment of sewage, and reduced applications of fertilizers have mitigated coastal pollution and are reducing frequency of HABs. National, regional and international marine pollution control programs that are adequately funded and backed by strong enforcement have been shown to be effective. Robust monitoring is essential to track progress.Further interventions that hold great promise include wide-scale transition to renewable fuels; transition to a circular economy that creates little waste and focuses on equity rather than on endless growth; embracing the principles of green chemistry; and building scientific capacity in all countries.Designation of Marine Protected Areas (MPAs) will safeguard critical ecosystems, protect vulnerable fish stocks, and enhance human health and well-being. Creation of MPAs is an important manifestation of national and international commitment to protecting the health of the seas.

AI summary Read the abstract
This review systematically examines how ocean pollution — spanning heavy metals, persistent organic pollutants, microplastics, pharmaceutical contaminants, and harmful algal blooms — threatens human health through seafood consumption, drinking water, and direct exposure, estimating nine million annual premature deaths attributable to global pollution and proposing policy priorities for marine pollution control.
Impact of Marine Pollution on Human Health and Well-being
AI summary Read the abstract
This review examined how marine pollution from diverse sources including microplastics, harmful algal blooms, persistent organic pollutants, and pathogens affects human health. The authors concluded that ocean pollution poses serious and multifaceted public health threats and recommended policy frameworks incorporating the 5R principles of reduce, reuse, recycle, refuse, and rethink to curb marine pollution.
Marine pollution: the global challenge of ocean contaminants and mitigation efforts
AI summary Read the abstract
A comprehensive review identifies plastic pollution, nutrient eutrophication, chemical contaminants, and ocean noise as interconnected drivers of marine ecosystem degradation, with plastic gyres and long-range pollutant transport reaching even remote polar regions. This is foundational to microplastic research as it contextualizes microplastics within the broader multi-stressor marine pollution crisis that requires integrated regulatory and technological solutions.
Mitigating the Impacts of Macro- and Microplastics on Marine Ecosystems: An Overview of Supporting Strategies and Cleanup Systems
AI summary Read the abstract
This review paper rounds up what researchers already know about tackling plastic pollution in our oceans, from laws banning single-use plastics, to eco-friendly bioplastics, to cleanup technologies for beaches and waterways. While it doesn't test new solutions itself, it matters for your health because ocean plastic breaks down into microplastics that end up in seafood, drinking water, and eventually our bodies, so reducing plastic pollution at the source is a key step toward limiting our own exposure.
Comprehensive Analysis of Marine Pollution: Sources, Environmental and Socioeconomic Impacts, and Sustainable Mitigation Strategies with Public Awareness
AI summary Read the abstract
This review comprehensively examined the sources, ecological and socioeconomic impacts, and mitigation strategies for marine pollution, emphasizing that microplastics are a widespread hazard that has infiltrated food chains and remote ocean areas. The authors advocated for integrated global responses including stricter regulations, advanced technologies, and international frameworks such as SDG 14 to achieve sustainable marine stewardship.
