In the GDR the benzo[a]pyrene (BaP) contents of vegetables grown in areas far from industrial plants range from 0.01 to 2.3 microgram/kg of fresh weight with a mean of 0.43 microgram/kg; and in the Hungarian People's Republic the BaP contents of such vegetables lie between 0.05 and 3.85 microgram/kg with a mean of 0.6 microgram/kg. The BaP contents of vegetables from areas near industrial plants or in the immediate proximity of emitters range from 0.15 to 12.4 microgram/kg (in the GDR) and from 0.05 to 19.6 microgram/kg (in the Hungarian People's Republic), being markedly superior to the values obtained with comparable vegetables from areas far from industrial plants. The BaP contents of samples from the Hungarian People's Republic collected near a relatively new petrochemical plant were 3.5 times as high as those of samples collected in areas far from industrial plants; and the BaP contents obtained with samples collected in the proximity of an old petrochemical plant were 8 times as high as those observed with samples collected in areas far from industrial plants. The contamination depends strongly upon the type of emitter. Samples collected in the GDR in the immediate proximity of coal-preparation plants (such as tar extraction, coking or carbon black plants) contained BaP contents 10 to 100 times as high as those found in samples collected in areas far from industrial plants. Targeted measures aiming at diminishing air pollution will widely reduce the contamination of harvested crops with cancerogenic hydrocarbons.
在民主德国，远离工厂地区种植的蔬菜中苯并[a]芘（BaP）含量为0.01至2.3微克/千克鲜重，平均为0.43微克/千克；在匈牙利人民共和国，此类蔬菜的BaP含量在0.05至3.85微克/千克之间，平均为0.6微克/千克。来自工厂附近地区或排放源附近的蔬菜中BaP含量在民主德国为0.15至12.4微克/千克，在匈牙利人民共和国为0.05至19.6微克/千克，明显高于远离工厂地区同类蔬菜的含量。在匈牙利人民共和国，在一座相对较新的石化厂附近采集的样本中BaP含量是远离工厂地区采集样本的3.5倍；在一座老石化厂附近采集的样本中BaP含量是远离工厂地区采集样本的8倍。污染程度在很大程度上取决于排放源类型。在民主德国，在选煤厂（如焦油提取厂、焦化厂或炭黑厂）附近采集的样本中BaP含量比远离工厂地区采集的样本高10至100倍。旨在减少空气污染的针对性措施将广泛降低收获作物被致癌烃污染的程度。
