Sister-chromatid exchanges (SCE) and chromosomal aberrations were studied in a population of floriculturists occupationally exposed to organophosphorus, carbamate and organochlorine pesticides. Blood samples from 36 individuals from a community of 154 persons of asiatic origin were obtained. Among the group sampled, 21 individuals exhibited at least one… (More)
A cytogenetic study was performed on workers of a leather tanning industry. Two different approaches for the biological monitoring of the individuals were used: chromosomal aberration analysis in peripheral lymphocytes and the frequency of micronucleated cells exfoliated in urine samples. 26 men working in the sections considered to present a greater risk… (More)
Nitroso-aldicarb was tested for its ability to induce sister-chromatid exchanges (SCE) and cell-cycle delay in human peripheral blood lymphocytes in vitro. This derivative of aldicarb induced a dose-dependent increase in SCE values per cell. In addition, a slight decrease in the successive mitotic progression of cells in culture was observed.
Aldicarb was tested for its ability to induce chromosomal aberrations in human peripheral lymphocytes in vitro, in the presence of an exogenous metabolic activation system. The pesticide induced an increase in the number of chromatid and chromosome breaks. The increase was higher in the presence of S9 mix. A positive linear association between frequencies… (More)
The aim of this work was to investigate whether the pesticide propoxur and its nitroso derivative nitroso-propoxur increased the frequencies of sister-chromatid exchanges and micronuclei in human lymphocytes in vitro. The results show that both chemicals were genotoxic in the tested system.
