Microplastics in Landfill Bodies: Abundance, Spatial Distribution and Effect of Landfill Age

Sustainability, Journal Year: 2023, Volume and Issue: 15(6), P. 5017 - 5017

Almost a quarter of the plastic produced in Europe still ends up landfills. In addition to loss valuable resources, this leads generation and accumulation microplastics The abundance refuse their spatial distribution landfill body have not been practically studied. current work, changes characteristics from 3 age sections Lapės regional landfill, Lithuania, depth 10–20 m were A 55 particles/g or 52.8 g/kg was found. lowest found old section, while highest young (numerical) middle-aged (mass) sections. Moreover, increased with landfilled waste depth, which may reflect fragmentation transport. Polyethylene polypropylene dominant polymer types all sections, films shape. carbonyl index PE calculated monitor oxidation. analysis showed an increase age, proving intensive degradation microplastics. Thus, landfills are large reservoirs potential sources.

Since the COVID-19 outbreak, use of disposable plastics has rapidly increased along with amount plastic waste. During fragmentation, microplastics and other chemical substances contained in are released. These then enter humans through food which could be problematic considering their hazardous potential. Polystyrene (PS), is widely used containers, releases large amounts (MPs), but no studies have investigated release mechanisms PS-MPs simultaneously exposed contaminants. Therefore, this study, effects pH (3, 5, 7, 9), temperature (20, 50, 80, 100 °C), exposure time (2, 4, 6, 8 h) on MPs were systematically examined. A quantitative/qualitative study styrene monomers was performed using microscopy-equipped Fourier-transformed infrared spectroscopy gas chromatography-mass spectrometry. The (36 items/container) pollutants (SEP), such as ethylene glycol monooleate (EGM), highest at 9, °C, 6 h, proportional to test time. Under same conditions, 2.58 μg/L monomer migrated liquid simulants. fragmentation proceeded by oxidation/hydrolysis accelerated strong positive correlation between SEPs indicates that follow process. However, a strongly negative shows migration does not process, its partition coefficient.
