any insects emanating from relevant industrial, trade or business premises and being prejudicial to health or a nuisance
artificial light emitted from premises so as t be prejudicial to health or a nuisance
noise emitted from premises so as to be prejudicial to health or a nuisance
noise that is prejudicial to health or a nuisance and is emitted from or caused by a vehicle, machinery or equipment in the street.

Any other matter declared by any enactment to be a statutory nuisance; and includes:

any well, tank, cistern, or water-butt used for the supply of water for domestic purposes which is so placed, constructed or kept as to render the water therein liable to contamination prejudicial to health, shall be a statutory nuisance (Public Health Act 1936, s 141).
