The air in a selected place is more likely to develop into extra polluted when firecrackers are burst on an overcast day with excessive humidity. This is because of a mixture of the pollution launched by the fireworks and the prevailing climate situations that entice these pollution nearer to the bottom.

Firecrackers launch a wide range of dangerous substances into the ambiance. These embody particulate matter (PM), carbon dioxide, carbon monoxide, nitrogen oxides, and sulphur dioxide. These emissions can mix to create a poisonous haze, which considerably reduces air high quality and visibility.

Overcast skies sometimes result in cooler days and a decrease mixing top, which is a layer of the ambiance the place pollution can disperse. When this top is decrease, pollution are trapped nearer to the bottom, resulting in greater concentrations. Most smog episodes coincide with cloudy skies for that reason.

Higher humidity exacerbates the issue. Water vapour within the air can work together with pollution to type secondary pollution. For occasion, sulphur dioxide and nitrogen oxides can combine with vapour to create acid rain. High humidity may also result in fog and haze, which may entice PM and different pollution and maintain them from dispersing.
