A pathway-resolved national model for quantifying environmental loads from pet-dog waste: A case study of South Korea
AI summary Read the abstract
Researchers built a national pathway-resolved mass-balance model for South Korea to quantify how pet-dog waste is disposed of across landfill, sewer, and open-environment routes, identifying it as an underappreciated but quantifiable source of microplastics and nutrients entering urban water systems.
Pet-dog waste (PDW) represents an emerging waste stream linking municipal solid waste and urban water systems, yet its pathway-specific environmental loads remain unquantified at national scale. We develop a pathway-resolved mass-balance model for South Korea that allocates PDW into three disp...

Quantifying microplastic stocks and flows in the urban agglomeration based on the mass balance model and source-pathway-receptor framework: Revealing the role of pollution sources, weather patterns, and environmental management practices
AI summary Read the abstract
Researchers developed a mass balance model using a source-pathway-receptor framework to quantify microplastic stocks and flows in an urban agglomeration, revealing how pollution sources, weather patterns, and environmental management practices collectively determine the transport of microplastics to receiving water bodies.
Environmental Pawprint of Dogs as a Contributor to Climate Change
AI summary Read the abstract
This review examined the overlooked environmental footprint of companion dogs, finding that they contribute to climate change and microplastic pollution through waste generation and plastic-containing products, with the rapidly growing global urban dog population amplifying these impacts.
The “plastic cycle”: a watershed‐scale model of plastic pools and fluxes
AI summary Read the abstract
This paper presented a watershed-scale conceptual model of plastic sources, fluxes, and fates — including landfill containment, environmental persistence, atmospheric interactions, and ocean export — arguing that terrestrial and freshwater plastic stocks are severely underappreciated in global accounting.
Understanding the Microplastic ‘model’: Applications of Modelling to Track Microplastics in Aquatic Ecosystems
AI summary Read the abstract
Researchers reviewed mathematical modelling techniques used to track how microplastics move and spread through rivers, oceans, and other aquatic environments. Understanding these models is critical for predicting where plastic pollution accumulates and which ecosystems and communities face the greatest exposure risk.
Dog poop bags: A non-negligible source of plastic pollution.
AI summary Read the abstract
This paper estimates that over 415 billion dog waste bags are used and disposed of globally each year, representing 0.76-1.23 million tons of plastic annually. Despite being a small fraction of total plastic waste, the extremely short use cycle of these bags makes them a notable and often overlooked source of plastic pollution.
