Results of a comparative analysis of the frequency and spectrum of cytogenetic anomalies are presented for reproductive (seeds) and vegetative (needles) samples taken from Scotch pine (Pinus sylvestris, L.) micropopulations growing at sites with differing levels of radioactive contamination in the Chernobyl NPP 30 km zone, and at the location of a facility for the processing and storage of radioactive wastes (the 'Radon' LWPE, near the town of Sosnovy Bor in the Leningrad Region). The data obtained indicate the presence of genotoxic contaminants in the environment of the tree micropopulations. Chemical toxins make the main contribution to the environmental contamination in the Sosnovy Bor area as compared with the influence of ionising radiation in the Chernobyl 30 km zone. The higher radioresistance of seeds of Scotch pine growing on the area of the 'Radon' LWPE and in the centre of Sosnovy Bor town was revealed with acute gamma-radiation.
本文给出了对取自苏格兰松(Pinus sylvestris, L.)微种群的繁殖样本(种子)和营养样本(针叶)进行细胞遗传学异常频率和谱的比较分析结果。这些微种群生长在切尔诺贝利核电站30公里区域内放射性污染水平不同的地点,以及一个放射性废物处理和储存设施(“氡”低放废物处理厂,位于列宁格勒州索斯诺维博尔镇附近)所在地。所获数据表明树木微种群环境中存在遗传毒性污染物。与切尔诺贝利30公里区域的电离辐射影响相比,化学毒素对索斯诺维博尔地区的环境污染起主要作用。在“氡”低放废物处理厂区域和索斯诺维博尔镇中心生长的苏格兰松种子,在急性γ辐射下表现出较高的抗辐射性。
