Question

Explain what was ultimately responsible for London’s “killer fog” in 1952.
in small paragraph

Answer 1

The Great Smog of December 1952 was ultimately caused by a huge build-up of pollutants from burning large quantities of low‑grade, high‑sulfur coal (domestic and industrial), which produced dense soot and sulfur dioxide that became chemically transformed into irritating acidic smog and particulates; a slow-moving anticyclone and temperature inversion trapped those emissions over London for days, producing lethal concentrations of pollution that caused thousands of deaths and prompted the 1956 Clean Air Act.
