“… 39 No other study has previously used this method to investigate MP’s weathering under natural environmental conditions. Potrykus et al 68 applied it to characterize the chemical modifications on a PP plastic sample after five years of degradation in a landfill. The authors reported a CI ranging from 0.37 to 1.29.…”

The seafloor is the major sink for microplastic (MP) pollutants. However, there is a lack of robust data on the historical evolution of MP pollution in the sediment compartment, particularly the sequestration and burial rate of small MPs. By combining a palaeoceanographic approach and state-of-the-art analytical methods for MP identification down to 11 μm in size, we present the first high-resolution reconstruction of MP pollution from an undisturbed sediment core collected in the NW Mediterranean Sea. Furthermore, we investigate the fate of MPs once buried in the sediments by evaluating the changes in the size distribution of the MPs and the weathering status of the polyolefins, polyethylene, and polypropylene. Our results indicate that the MP mass sequestered in the sediment compartment mimics the global plastic production from 1965 to 2016. We observed an increase in the weathering status of the polyolefins as the size decreased. However, the variability in the size and weathering status of the MPs throughout the sedimentary record indicated that these pollutants, once incorporated into sediments, remain preserved with no further degradation under conditions lacking remobilization.

“…Recent plastics research has focused on human health and environmental issues, such as the prevalence of endocrine-disrupting compounds in plastics and the long-term contamination of the atmosphere by plastic waste (North and Halden 2013 ). The majority of plastic waste is non-biodegradable, with a lifespan ranging from less than a year to more than 50 years (Potrykus et al 2021 ). Furthermore, when plastic waste litter is exposed to UV radiation, photo- and thermo-oxidative degradation occurs, resulting in secondary microplastics or microbeads with a size of 10–500 m (Andrady 2011 ).…”

Plastic pollution has become a serious transboundary challenge to nature and human health, with estimation of reports published — predicting a twofold increase in plastic waste by 2030. However, due to the COVID-19 pandemic, the excessive use of single-use plastics (including face masks, gloves and personal protective equipment) would possibly exacerbate such forecasts. The transition towards eco-friendly alternatives like bio-based plastics and new emerging sustainable technologies would be vital to deal with future pandemics, even though the use or consumption of plastics has greatly enhanced our quality of life; it is however critical to move towards bioplastics. We cannot deny the fact that bioplastics have some challenges and shortcomings, but still, it is an ideal option for opt. The circular economy is the need of the hour for waste management. Along with all these practices, individual accountability, corporate intervention and government policy are also needed to prevent us from moving from one crisis to the next. Only through cumulative efforts, we will be able to cope up with this problem. This article collected scattered information and data about accumulation of plastic during COVID-19 worldwide. Additionally, this paper illustrates the substitution of petroleum-based plastics with bio-based plastics. Different aspects are discussed, ranging from advantages to challenges in the way of bioplastics.

“…In addition, the hydroxyl index (HI) was defined the ratio of the area of the hydroxyl peak in the range of 3700 cm −1 -3000cm −1 to that of the methyl peak of 1495 cm −1 -1427 cm −1 . 31 The spectrum data were analyzed using Omnic 8.2.0.387, and the spectra were drawn using R.…”
