Análise da poluição atmosférica na América do Sul durante a propagação da COVID-19
Resumo
A pandemia global causada pelo coronavírus SARS-CoV-2 teve um impacto significativo em vários setores da sociedade, incluindo saúde, ciência, economia e, principalmente, uma notável mudança nos aspectos ambientais. Este estudo focou na análise da propagação da COVID-19 na América do Sul, destacando os impactos das políticas de lockdown na qualidade do ar das principais cidades de 13 países durante a pandemia. Além disso, utilizando modelos estatísticos de regressão simples, caracterizamos o comportamento dos casos diários acumulados de Covid-19 nos 13 países analisados. A estratégia de fechamento foi uma das primeiras medidas adotadas pela Organização Mundial da Saúde (OMS) para controlar a propagação do coronavírus, resultando em uma redução significativa do tráfego e das atividades industriais. Essa medida melhorou significativamente a qualidade do ar em quatro das 13 cidades sul-americanas estudadas, a saber: Guarulhos (Brasil), Santiago de Chile (Chile), Bogotá (Colômbia) e Lima (Peru); com reduções de PM2,5, PM10 e ozônio (O3). Os padrões observados na propagação da COVID-19 na América do Sul e as análises de impacto ambiental fornecidas neste estudo demonstram o impacto significativo das atividades comerciais e industriais, que poderiam orientar estratégias futuras para reduzir a poluição e os problemas de saúde associados
