A stack emits \( 60 \) g/s and produces a maximum ground level concentration of \( 180 \) micrograms per cubic metre. Halving the emission gives
Answer: C
Correct answer: 90 micrograms per cubic metre
Ground-level concentration is directly proportional to the emission rate, everything else being unchanged - the dispersion is the same whatever the plume carries. So halving \(Q\) halves the concentration:
\[ 180 \times \tfrac{1}{2} = 90\ \mu\text{g/m}^3 \]
