Answer 13

you will need a machine for air id guess,
inhaling is not a good idea ;)

exactly...so it is difficult to detect pollution in air than in any water...so u got d ans..:)

Answer 15

uhmm we have machines for determining pollution levels in both still water and air

Answer 16

looking at the water may not tell u exactly what the "level" of pollution

u will need to use machines for determining levels in both cases
