How does Air get polluted?
? Air pollution happens when aerosols (solid and liquid particles) & certain gases end up in our air.
? Natural sources of aerosols include sea salt generated from breaking waves, dust from dry regions, or particles released by wildfires.
? Artificial aerosols include pollutants such as sulphur and nitrogen oxides emitted from power plants, factories & automobiles.
During stay at home & self quarantine:
? There has been a drastic drop in the levels of nitrogen oxides over cities and industrial areas across the world since lockdowns began in response to the COVID-19 pandemic.
? In contrast, a study found that a secondary pollutant, ground-level ozone (bad ozone), has increased in China.
? This is created by chemical reactions between two primary pollutants in the presence of heat and sunlight, & can still be a problem.
? Nonetheless, there has been an overall improvement in air quality.
Questions to ponder once this lockdown eases?
? Will the overall air pollution be likely to worsen again?
? Can the breath of fresh air associated with the Covid-19 lockdown spark a clean air movement and lead to more strict rules for factories and automobiles?
Let’s do our part with a simple start:
♻️ Let’s be proactive to reduce air pollution & keep the air cleaner by conserving electricity by turning lights & appliances off when not in use at home.
