Match List-I (Pollutant) with List-II (Method of Measurement)
 

List-I (Pollutant)List-II (Method of Measurement)
A. O\(_3\)I. Flame Photometry
B. SO\(_2\)II. Gas Chromatograph
C. PbIII. UV Spectrometer
D. HydrocarbonsIV. Atomic absorption analysis

Show Hint

Memory aid for pollutant measurement methods:
• O\(_3\) \(\to\) UV Spectrometer (ozone is the UV shield -- naturally linked to UV)
• SO\(_2\) \(\to\) Flame Photometry (sulphur burns with characteristic glow)
• Pb \(\to\) Atomic Absorption (standard technique for all heavy metals)
• Hydrocarbons \(\to\) Gas Chromatography (volatile organics separated by GC)
