Evaluating emissions and air quality implications of residential waste incineration
AI summary Read the abstract
This study assessed the occurrence of microplastics in freshwater zooplankton from a large lake system. Zooplankton from surface waters contained higher microplastic concentrations than deep-water populations, and ingestion rates correlated with surface water microplastic density, indicating that exposure is driven by surface contamination.
In Europe mainly at winter season the PM levels exceed air quality limits, which correlated with the operation of solid-fired boilers. More and more people are returning to using these devices due to energy shortage caused by the pandemic and regional conflicts. In addition, the phenomena of co-burning fuels and municipal waste in residential boilers in primarily fuel poverty households increases further the amount of pollutants in the atmosphere. This study aims to correlate the quantity and quality of air pollutants with the type of fuel (wood and wastes) burned. Combustion experiments were conducted using oak fuel mixed with three waste groups: (1) plastics (PP, HDPE, PET); (2) textiles (polyester-PES, cotton-COT); and (3) papers (cardboard-CARD, glossy coated paper-GCP, 84C/PAP). The addition of waste to wood fuel altered the morphology of emitted particles. While waste burning doesn't always increase particle quantity, it significantly raises PAH concentrations. A strong relationship exists between waste type, particle morphology, and PAH quality, where with lower molecular weight PAHs linked to tar agglomerates and higher ones to soot agglomerates with inorganic crystals.

Gaseous and particulate emissions from PET and PS co-combustion with biomass in a domestic boiler: Role of air intake and waste proportion
AI summary Read the abstract
Some people illegally burn plastic waste with wood pellets in home heating systems to save money, but this study found that doing so can release dramatically more toxic emissions (like carbon monoxide and harmful gases), especially when the fire isn't getting enough air—up to 97 times more than burning wood alone. The takeaway: if your home or neighborhood heating system isn't properly maintained or ventilated, burning plastic waste can seriously worsen the air you breathe, making it a real health risk, not just an environmental one.
Microplastics as emerging contaminants in textile dyeing sludge: Their impacts on co-combustion/pyrolysis products, residual metals, and temperature dependency of emissions
AI summary Read the abstract
Researchers studied how microplastics in textile dyeing sludge affect the pollutants released when the sludge is burned or heated for disposal. The presence of polyethylene and polypropylene microplastics increased the release of harmful gases and changed how toxic metals behaved during combustion. This means that microplastic-contaminated industrial waste can generate additional air pollution when disposed of through burning, adding to the pollutants people breathe.
Plastic burning: An important global source of atmospheric nanoplastic particles
AI summary Read the abstract
Researchers conducted smoldering laboratory experiments with PVC, PP, LDPE, PET, and PS plastics and used aerosol mass spectrometry to characterise the physical and chemical properties of nanoplastic particles emitted, finding that plastic burning generates large quantities of nanoplastics and thermo-oxidation products that represent a significant but poorly quantified global source of atmospheric nano-sized plastic particles.
Plastic Burning Particulate Matter as a Source of Environmentally Persistent Free Radicals and Reactive Oxygen and Chlorine Species

Researchers characterized particulate matter generated by burning common plastic types, finding that it contains environmentally persistent free radicals and reactive oxygen and chlorine species at levels with significant implications for air quality and human health near open plastic burning sites.
Pyroplastic particulate matter from fire events adds a hidden dimension of plastic pollution
AI summary Read the abstract
When plastic burns in wildfires, house fires, or trash burning, it doesn't just disappear, it creates a new type of tiny airborne particle that this review calls "pyroplastic particulate matter." These particles are especially concerning because they combine the lasting presence of microplastics with toxic chemicals from smoke (like tar-related compounds and heavy metals), and they're small enough to breathe deep into your lungs. This review pulls together existing research to argue that as fires increasingly burn through plastic-filled homes and landscapes, we need better tools to detect and understand this pollution, especially for people living near fire-prone are
