Abstract
Phosphate, a common fertilizer used to supplement soil with phosphorous induced 1.10%, 1.26% and 1.43% of micronuclei and 18.3%, 21.0% and 24.6% of chromosomal abnormalities upon three different doses. The frequency of abnormalities increased with increase of doses. Polyploidy and aneuploidy were common among gross, while acentric fragments, minute fragments, chromatid breaks were more common among individual type of abnormalities. The individual type of damages were more prominent than gross type. This might be due to the formation of electrophilic radicals/ions during the metabolization of mutagens that attack the nucleophlic site of DNA leading to structural changes in chromosomes. These chemicals probably cause an increase formation of a base analogue to act as a mutagen that induce chromosomal and cellular abnormalities.
