Air pollution is a cause of morbidity and mortality with open landfills also being major sources of air
pollutants. People living near exposed landfills are at more risk of health hazards. This study aims to assess the knowledge,
attitude and practice about air pollution, related health hazards and prevention among residents living near an open
landfill in Vaniyambadi town. A cross sectional study from September to October 2020 among 93 residents living near
an open landfill was conducted. The study revealed that the residents had good knowledge about air pollution and its
health hazards and with good prevention practices. Personal Protective Equipment usage was found to reflect the positive
impact of the pandemic related Information Education Communication activities with everyone using face masks. The
results showed that 26% had below average knowledge about air pollution, sources and causes, which warrants the need
to emphasize on addressing the gap in knowledge and practice among residents near landfill.
