![]() ![]() To prevent the rise of coronavirus sickness, every country’s government has established social distancing regulations and forced its inhabitants to remain in their homes. ![]() These variables resulted in a significant drop in nitrogen dioxide (NO 2) and particulate matter (PM 2.5, diameter smaller than 2.5 µm) concentrations all across the world (Cui et al. Though these policies or regulations may have a significant impact on the economies of most countries, they have some negative or positive effects on the environment, such as a substantial drop in the greenhouse gas emissions that have not been seen since World War II, as many industries in the world halted production and vehicle usage drastically decreased. Almost all countries are currently focusing their efforts to prevent the spread of COVID-19 disease by enacting policies such as the complete closure of public places (Liu et al. COVID-19 has made a great impact all across the world. Humans were infected mostly by droplets, interactions, and airborne transmissions. ![]() Coronavirus may have been transmitted from bats to people, according to one hypothesis (Brennecke et al. It was first reported in Wuhan, China, in December 2019, and soon spread throughout the country, becoming a global disease (Ali and Alharbi 2020 Zambrano-Monserrate et al. Thermochemical conversions of solid wastes including medical wastes and for treated wastewater sludge/biosolids offer several advantages through recovering the resources and energy and stabilizing/destructing the toxins/contaminants and microplastics in the precursors.ĬOVID-19 has spread over the world, causing a global health emergency. This review also suggests strategies to create long-term environmental advantages. Furthermore, the significant usages of anti-bacterial hand sanitizers, disinfectants, and pharmaceuticals have increased the accumulation of various toxic emerging contaminants (e.g., triclocarban, triclosan, bisphenol-A, hydroxychloroquine) in the treated sludge/biosolids and discharged wastewater effluent, posing great threats to the ecosystems. The extensive usage of face masks increased the release of microplastics/nanoplastics (183 to 1247 particles piece −1) and organic pollutants in land and water bodies. However, according to this review, the pandemic put enormous strain on the present waste collection and treatment system, resulting in ineffective waste management practices, damaging the environment. As a result, this review highlights the positive and the long-term negative environmental effects of the COVID-19 pandemic by evaluating the scientific literature. ![]() Although many studies are confirming the short-term improvements in air quality in several countries across the world, the long-term negative consequences outweigh all the claimed positive impacts. The COVID-19 pandemic not only has caused a global health crisis but also has significant environmental consequences. ![]()
