Air pollution causes severe physical and psychological health complications. Considering China’s continuously-deteriorating air quality, this study aimed to assess the self-reported effects of air pollution on the behavior and physical health of the students of 13 densely populated cities, and their awareness, practices, and perception of air pollution and its associated public health risks. A detailed, closed-ended questionnaire was administered to 2100 students from 54 universities and schools across China. The questionnaire, which had 24 questions, was categorized into four sections. The first two sections were focused on air pollution-associated behavior and psychology, and physical effects; while the final two sections focused on the subjects’ awareness and perceptions, and practices and concerns about air pollution. The respondents reported that long-term exposure to air pollution had significantly affected their psychology and behavior, as well as their physical health. The respondents were aware of the different adverse impacts of air pollution (respiratory infections, allergies, and cardiovascular problems), and hence had adopted different preventive measures, such as the use of respiratory masks and glasses or goggles, regularly drinking water, and consuming rich foods. It was concluded that air pollution and haze had negative physical and psychological effects on the respondents, which led to severe changes in behavior. Proper management, future planning, and implementing strict environmental laws are suggested before this problem worsens and becomes life-threatening.

PM 10 ), SO 2 , NO 2 , and O 3 over six districts of Malakand division, Northern Pakistan. The second part of the study appraised the associated self-reported effects of air pollution on Pakistani students and the practices, perceptions, and awareness of the students regarding air pollution through a closed-ended questionnaire, administered to 4100 students. The first section of the questionnaire was focused on the physical effects associated with air pollution; the second section was focused on air pollution-linked behavior and psychology; the third portion was focused on perception and awareness of the subjects, whereas the final section was focused on practices and concerns of the subjects regarding air pollution. The students reported that exposure to air pollution significantly affected their physical health, behavior, and psychology. The subjects were aware of the different air pollutants and health complications associated with air pollution, and therefore had adopted preventive measures. It was concluded that air pollution had adverse impacts on the physical and psychological health of the respondents, which consequently altered their behavior. Mass awareness, proper mitigating plan, suitable management, and implementation of strict environmental laws are suggested before the air gets further polluted and becomes life-threatening.

About 50% of the world's low-income population uses biomass fuel as their primary source for cooking [1], while the usage is even higher in developing countries. The burning of biomass fuel emits pollutants into the air, which are detrimental to human health. Some of those pollutants are suspended particulate matter, carbon monoxide, polyaromatic hydrocarbons, formaldehyde, and volatile organic compounds [2]. These pollutants can cause many health diseases in humans, specifically respiratory problems such as chronic bronchitis [3] and bronchial asthma, and can cause tuberculosis and abnormalities in newborns [4, 5]. The use of solid fuels for cooking in rural areas of developing countries cannot be denied because it is used in many forms such as coal, charcoal, wood, straw, dung cakes, and agricultural crop residues [3]. Furthermore, due to limited alternative sources of fuel in rural areas of Pakistan people are heavily relying on solid fuel for cooking. Mostly women and children
