“…However, these differences are in the form of peaks which leads us to say that the problem could come from the way the CO 2 is calculated (as it is an estimated value by the CJMCU-30 sensor). Results and observations presented in Figure 5, concerning impact of the pandemic lockdown on AP, are substantially in accordance with those in different regions in the world, as an example in China [29], in India [30], or Brazil [31]. Temperature and humidity values are presented respectively in Figure 5(a) and Figure 5(b).…”

The composition of the air has been visibly altered as a result of human activity, resulting in what we term air pollution. It is no longer necessary to prove the effects on ecosystems and human health. Under these conditions, governments all around the world are working to address this issue, notably in the area of real-time air quality monitoring. The implementation of a data provider is a necessary step in achieving this goal. In that case, this study presents a hardware and software solution to provide a low-cost deployable device to acquire environmental data related to AP such as CO, CO2, NH3, and NO2, along with temperature and humidity. In addition to an user interface development, a complete circuit layout and a set of software criteria are set up to ensure a reliable implementation, data collection, and network communications. The results demonstrated that the device is capable of effectively obtaining real-time data. The analysis results indicate a link between environmental conditions and parameter values. This system deployment will ultimately contribute to providing a more elaborate mapped data distribution, according to a better understanding of our environment.

“…Other noteworthy studies in the city/state of São Paulo were Bravo et al ( 2016 ) who, in addition to relating hospital deaths to air pollution, also observed that the cardiovascular effects of PM 10 were more significant in population groups with less schooling (indicating the “non-democratization” of pollution); Pérez-Martínez et al ( 2017 ) who observed that policies related to transport/traffic can have a significant impact on reducing pollutants based on their study on the restriction of heavy diesel vehicles; Nakada and Urban ( 2020 ), Rudke et al ( 2021 ), and Cirqueira et al ( 2022 ) who studied the effects of the COVID-19 pandemic (lockdowns and mobility restrictions) on pollution levels and noticed very heterogeneous results, concluding that the economic, health and vehicular traffic particularities of each city or region in the state of São Paulo should be taken into account in the search for emission mitigation strategies.…”

2030 Agenda: discussion on Brazilian priorities facing air pollution and climate change challenges

The advance of human activities in a disorderly way has accelerated in recent decades, intensifying the environmental impacts directly linked to these practices. The atmosphere, essential for the maintenance of life, is increasingly saturated with pollutants, offering risks to practically all the inhabitants of the planet, a process that, in addition to causing illness and early mortality, is related to serious financial losses (including in the production of goods), dangerous temperature increase and severe natural disasters. Although this perception is not recent, the global initiative to control the different mechanisms that trigger the commitment of biodiversity and irreversible climate changes arising from pollution is still very incipient, given that global initiatives on the subject emerged just over 50 years ago. Brazil is a territory that centralizes many of these discussions, as it still faces both political and economic obstacles in achieving a sustainable growth model as it was agreed through the United Nations 2030 Agenda. Even though there is little time left for the completion of these goals, much remains to be done, and despite the fulfillment of this deadline, the works will certainly need to be extended for much longer until an effective reorientation of consciousness occurs. Scientific researches and discussions are fundamental tools to the understanding of issues still little explored in this field.
