Air pollution can be referred to as the release of pollutants into the air because of a mixture of gasses and particles in harmful amounts that are released into the atmosphere due to natural sources and human activities. The effect of air pollution on human health can increase mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections. In the least developed countries such as in Bangladesh, Pakistan, India, Mongolia and Afghanistan they suffered from severe air pollution due to lack of exposure and awareness about air pollution and the consequences to human health. Besides that, the outbreak of Covid-19 pandemic was declared as a global health emergency and the government around the world issued a lockdown to prevent the widespread of Covid-19 viruses. That is why this study investigated the knowledge, attitude and perception of air pollution during Covid-19 pandemic in Malaysia.
