# Waarschuwings meetnet

A warning network measuring high concentrations of sulphur dioxide has been put into operation in residential districts in the Rijnmond area. 31 so-called sniffer poles are set up in the districts, measure the concentrations and transmit the results to a computer at a central office. A woman reported an odour nuisance to the control centre by telephone, after which an official went to investigate and informed the factory of the odour. Some residents give their reaction to the odour nuisance.
