Since January 2020, studies report reductions in air pollution among several countries due to social isolation measures, which have been adopted in order to contain the coronavirus outbreak progress (COVID-19). This study aims to evaluate the change in the atmospheric pollution levels by NO and NO 2 in São Paulo City for the social isolation period. The NO and NO 2 hourly concentrations were obtained through air quality monitoring stations from CETESB, from January 14, 2020 to April 12, 2020. Mann-Kendall and the Pettitt tests were performed in the air pollutant time series. We observed an overall negative trend in all stations, indicating a decreasing temporal pattern in concentrations. Regarding NO, the highest absolute decrease rates were observed in the Congonhas (− 6.39 μg m −3 month −1 ) and Marginal Tietê (− 6.19 μg m −3 month −1 ) stations; regarding NO 2 , the highest rates were observed in the Marginal Tietê (− 4.45 μg m −3 month −1 ) and Cerqueira César (− 4.34 μg m −3 month −1 ) stations. In addition, we identified a turning point in the NO and NO 2 series trends that occurred close to the start date of the social isolation period (March 20, 2020). Moreover, from statistical analysis, it was found that NO 2 is a suitable surrogate for monitoring economic activities during social isolation periods. Thus, we concluded that social isolation measures implemented on March 20, 2020 caused significant changes in the air pollutant concentrations in the city of São Paulo (as high as − 200% in NO 2 levels).

Dampak Pelaksanaan Pembatasan Sosial Berskala Besar (PSBB) Terhadap Konsentrasi PM10 di Pekanbaru. Salah satu faktor penurunan kualitas udara dapat disebabkan oleh aktivitas manusia. Penetapan Pembatasan Sosial Berskala Besar (PSBB) karena pandemi Covid-19 mengakibatkan penurunan aktivitas masyarakat diluar ruangan. Tujuan penelitian ini adalah membandingkan kondisi kualitas udara di Pekanbaru sebelum dan saat diterapkan PSBB. Data yang digunakan adalah data konsentrasi PM10 hasil pengukuran PM10 Analyzer, BAM1020. Statistik deskriptif dan uji Mann-Whitney U test sebagai uji non-parametrik untuk menentukan perubahan signifikansi dari PM10 sebelum dan saat PSSB. Hasil penelitian menunjukkan bahwa sebelum dan saat PSBB, konsentrasi PM10 di Pekanbaru berada dalam kategori baik (0-50 µg/m3). Berdasarkan distribusi frekuensi kondisi sebelum PSBB, konsentrasi PM10 lebih tinggi jika dibandingkan saat kondisi PSBB. Kemudian berdasarkan polar plot sebaran konsentrasi PM10 bervariasi dengan konsentrasi terbesar sebelum PSBB yaitu antara 12-14 µg/m3 pada arah Barat Laut, sedangkan untuk kondisi saat PSBB konsentrasi terbesar antara 9-10 µg/m3 pada arah Timur Laut. Berdasarkan rata-rata periode waktu per jam dan harian menunjukkan bahwa konsentrasi PM10 cenderung lebih tinggi saat malam hari dibandingkan siang hari dan konsentrasi PM10 tertinggi terjadi pada hari Selasa dan terendah pada hari Minggu. Hasil Uji Mann-Whitney menunjukkan ada perubahan yang signifikan dalam konsentrasi PM10 sebelum dan saat PSBB di Pekanbaru.

Since January 2020, some studies have been reporting a reduction in air pollution in several countries due to social isolation measures, which have been adopted in order to contain the coronavirus outbreak progress (Covid-19). This study aims to evaluate the change in the atmospheric pollution levels by NO and NO2 in São Paulo city in the social isolation period. The NO and NO2 hourly concentrations were obtained through air quality monitoring stations from CETESB, from January 14 to April 12, 2020. Mann-Kendall and the Pettitt tests were performed in the air pollutants time series. We observed an overall negative trend in all stations, indicating a decreasing temporal pattern in concentrations. Regarding NO, the highest decrease rates were observed in Congonhas (-6.39 µg.m-3month-1) and Marginal Tietê (-6.19 µg.m-3month-1) stations; regarding NO2, the highest rates were observed in Marginal Tietê (-4.45 µg.m-3month-1) and Cerqueira César (-4.34 µg.m-3month-1) stations. In addition, we identified a turning point in the NO and NO2 series trends that occurred close to the start date of the social isolation period (March 20, 2020). Moreover, from statistical analysis, it was found that NO2 is a suitable surrogate for monitoring economic activities during social isolation period. Thus, we concluded that social isolation measures implemented in March 20, 2020 caused significant changes in the air pollutants concentrations in São Paulo city (as high as -200% in NO2 levels).
