[Gas cookers as a source of benz(a)pyrene emission]

The spectrofluorimetric method of bez(a)pyrene was used without separating it from other polycyclic aromatic hydrocarbons. On the basis of that method the content of that compound was measured in air contaminated with gas after burning of gas cookers. The study showed that this compound is not present in Warsow when earth gas is burning, but burning of propane-butane mixture contaminates air with this compound in a considerable degree.
