An investigation is performed to determine 3,4-benzpyrene content in the Sofia area (in a single spot), covering a one-year period (1970), on the basis of mean monthly concentrations established through gas chromatography, and compared to some of the averaged meteorologic data. The correlation between 3,4-benzpyrene concentrations and some meteorologic factors found is corroborated by the clearcut seasonal fluctuations of 3,4-benzpyrene concentrations in the atmospheric air. An inversely proportional dependence is established of 3,4-benzpyrene concentration to the summed up radiation, and directly proportional--to the dust amount. A rise of 3,4-benzpyrene concentration under conditions of the various types of temperature inversions, and a complex effect of meteorologic factors have been also noted. Moreover, an attempt is made at establishing the washing effect of rainfalls, and it has been found that up to a certain extent, such an effect really exists. The study performed shows in a clearcut manner that 3,4-benzpyrene content is considerably influenced by a variety of meteorologic factors.
基于通过气相色谱法确定的月平均浓度，对索非亚地区（单个地点）1970年全年的3,4 - 苯并芘含量进行了调查，并与一些平均气象数据进行了比较。大气中3,4 - 苯并芘浓度的明显季节性波动证实了所发现的3,4 - 苯并芘浓度与一些气象因素之间的相关性。确定了3,4 - 苯并芘浓度与总辐射成反比，与灰尘量成正比。还注意到在各种类型的逆温条件下3,4 - 苯并芘浓度会升高，以及气象因素的综合影响。此外，还尝试确定降雨的洗涤作用，并且发现这种作用在一定程度上确实存在。所进行的研究清楚地表明，3,4 - 苯并芘含量受到多种气象因素的显著影响。
