Special Issue Information

Dear Colleagues,

Plastic pollution has become an increasingly important global issue. Over 360,000,000 metric tons of plastics are manufactured annually, and this number is still increasing. However, only a limited amount of plastic waste is recycled, which poses a great challenge for the sustainability of plastics. To achieve the United Nations’ 2030 Sustainable Development Goals (SDGs) in a timely manner, it is urgent and of great significance to comprehensively understand the sources and distribution of plastic wastes, their environmental migration, transformation, and their crushing and aging. It is also critical to find ways to prevent and mitigate plastic pollution, and to develop more sustainable technologies to treat/recycle the current plastic wastes and new green strategies to produce more biodegradable plastics. For instance, recently, biotechnology, an efficient, green, and environmentally friendly method, has shown great potential in dealing with PET plastic pollution. The Special Issue seeks high-quality studies on, but not limited to, the following topics:

  • Sources and distribution of plastic wastes;
  • Environmental migration, transformation, crushing and aging of plastics;
  • Formation and migration of micro- and nanoplastics;
  • Enrichment of micro- and nanoplastics in the environment;
  • Sustainable technologies in prevention, mitigation, and recycling of plastic waste;
  • Sustainable technologies in developing green and biodegradable plastics.

Given the emerging studies and increasing importance in this area, we believe this Special Issue will surely attract a large number of submissions and have a huge impact on the community.

Microplastic (MP) pollution is a growing concern in every known ecosystem. However, MP presence in groundwaters and the ecological impact they can have on groundwater fauna is still poorly investigated. Here, we assess the presence of MPs in three Italian groundwater bodies, comprising two karst caves and two monitoring bores of a saturated alluvial aquifer. In addition to water samples, groundwater invertebrates were collected to assess their potential ingestion of MPs. For water samples, chemical characterization of polymers was done by Fourier Transform Infrared Spectroscopy (FTIR) 2D imaging, while fauna samples were analyzed with a tandem microscopy approach (fluorescence microscopy and FTIR). The abundance of MPs in water samples varied from 18 to 911 items/L. The majority of MPs were fibers (91%), with a mean size in the range of 100 µm and 1 mm. Black, red, and blue were the most abundant colors (30%, 25%, and 19%, respectively). The most abundant polymer was artificial/textile cellulose (65%), followed by PET (21%). MPs were found in every groundwater taxon. Pellets were the most abundant in each specimen (87% on average), while the largest were fragments, with a mean dimension of 26 µm. Cellulose was found to be the most abundant polymer (51%). This study is the first to highlight the presence of MPs ingested by groundwater fauna. Further investigations are urgently required to assess the potential ecological impact MPs can have on the resident fauna in these sensitive ecosystems. Full article
