The Impacts of Plastic Waste from Personal Protective Equipment Used during the COVID-19 Pandemic.

The period from 2019 to 2022 has been defined by the COVID-19 pandemic, resulting in an unprecedented demand for and use of Personal Protective Equipment (PPE). However, the disposal of PPE without considering its environmental impact and proper waste management practices has become a growing concern. The increased demand for PPE during the pandemic and associated waste management practices have been analyzed.

Impacts of illegal fishing in the inland waters of the State of Santa Catarina -Brazil.

Fish stocks are being severely depleted, marine habitats are threatened and marine pollution is on the rise due to discarded fishing gear. This equipment is generally from illegal, unreported and unregulated fishing, leading to incidental fishing and sometimes ghost fishing. In this study, data obtained from reports produced by the Environmental Military Police in Santa Catarina, Brazil, on gill nets fixed in the coastal area and at the baseline limit of this state, for the period of 2019 to 2020, were analyzed.

Influence of non-thermal plasma reactor geometry and plasma gas on the inactivation of Escherichia coli in water.

The inactivation of bacteria Escherichia coli (E. coli) by non-thermal plasma (NTP) was investigated using argon, air and 1:1 mixture of air/Ar as plasma gas on five different reactors. The experiments were carried out in triplicate in each reactor, using 60 mL of distilled water pre-inoculated with E.

Use of Cold Plasma To Inactivate Escherichia coli and Physicochemical Evaluation in Pumpkin Puree.

This work aimed to study the pumpkin puree processing by cold plasma corona discharge as an alternative to heat treatment to reduce Escherichia coli contamination and evaluate physicochemical alterations, using argon (Ar) as the process gas. The treatment time to verify E. coli inactivation was between 2 and 20 min, while physicochemical alterations were analyzed at 5, 10, 15, and 20 min.
