“…Carbaryl causes a reversible block in metaphase, spindle microtubule depolymerization, displacement of chromosomes to the periphery of the cell and, concomitant to this, a remarkable progression of the cytoplasmic changes typical of anaphase and telophase (13,15,33). Though carbaryl is relatively safe to mammals, 10 M and 1mM carbaryl causes damage to hepatocytes (34). Apparently less harmful carbaryl has some serious effects on human, as evidenced by morphologic abnormalities and genotoxic defects of spermatozoa, DNA breakage and chromosomal aberrations (35).…”
