Article Synopsis
- COVID-19 began in late 2019 in Wuhan, China, leading to global spread and the implementation of quarantine measures to control the virus.
- The article examines the environmental impact of COVID-19 in Mato Grosso do Sul, Brazil, by analyzing nitrogen dioxide (NO) levels from 2005-2019 and during the pandemic in 2020, showing a short-term improvement in air quality due to reduced activities.
- While a significant decrease in NO levels was noted during the lockdown, pollution levels returned to pre-pandemic levels as economic activities resumed, highlighting the temporary nature of air quality improvements and offering insights for future environmental policies.
Thermal lens (TL) spectrometry was applied to soybean biodiesel samples, in order to assess the behavior of their thermo-optical properties during the preparation before and after the washing process. The study was based on the thermal diffusivity parameter, which is highly sensitive and is related to the chemical composition of the sample. The results showed a difference of approximately 20% between the initial (unwashed) and the final (washed) steps of biodiesel production.
