The outbreak of COVID-19 has spread rapidly across the world. To control the rapid dispersion of the virus, many countries have imposed national lockdown policies to practise social distancing. This has led to reduced human activities and hence primary air pollutant emissions, which caused improvement of air quality as a side-product.A well structured questionnaire containing 16 questions was circulated among College students. The questionnaire has covered basic demographic data such as age, gender and about the awareness of change in the environment during lockdown. Results show that human activities were lowered significantly during the period. This reduction in human activities has played a significant role in the improvement of the environment. Although the lockdown has contributed to a positive impact on air quality, it is important to take into account the negative impacts on social aspects, considering the deaths caused by COVID-19 and also the dramatic economic effects. From this study we may conclude that there is awareness among college students and this helps in improving the environment during normal days.
