ANALYSIS OF SPONTANEOUS MUTAGENESIS LEVEL, IN PLASTIC FACTORY WORKERS TAIZ CITY, IN YEMEN REPUBLIC
We have done the first analysis of aberrations metaphase chromosomes of peripheral blood lymphocytes in plastic factory workers Taiz city, in Republic of Yemen. The basic types of chromosomal aberrations., Number of damaged chromosomes was 3,44 ± 0,42%, breaks - 3,46 ± 0,42%, dominated by single fragments with a frequency of 2,36 ± 0,26%, the frequency of binary fragments corresponded 0, 79 ± 0,14%. Determine the average frequency of cells with chromosome aberrations (3,39 ± 0,42%). Dicentric chromosomes without paired fragments occur with a frequency of 0.04 per 100 cells, which may indicate chronic mutagenic effects in somatic cells, harmful production workers.
