Because of logistical and regulatory constraints, you are not able to operate a generator outdoors, so it will remain in your kitchen where the ceiling height is $2\mathrm{.}56$ m and a floor area of $33\mathrm{.}22$ m$2.$ There are windows that allow light in but cannot be opened. If you operate the diesel generator in this space $($without ventilation$),$ what concentration do pollutants reach in the kitchen after one day of operation? Do you have any concerns?
