Sažetak
PCP is known as a very efficient biocid which range of use was very wide just few years ago. Eventually, it"s use was stopped in many countries including Croatia, when shown that PCP was highly toxic especially on water organisms (Gates and Tjeerdema, 1993, Shofer and Tjeerdema 1993), but as well on some land animals (Erlich 1990, Jansson and Jansson 1991) and plants. However, PCP is still present in the environment, mostly by degradation of today still frequently used insecticide Lindan. Roots of shallot (Allium ascalonicum auct.) were exposed to different concentrations of Na-PCP: 0.001; 0.01, 0.1 and 1 mg/l during 24 hr. pH values of tested solutions were adjusted to 3, 5 or 8. Root-tip cells were analysed either after 24 hr of treatment or after the treatment and recovery of 48 hr in water. Na-PCP revealed genotoxic effect in shallot root-tip cells of which extent depended on concentration and pH value. Chromosomal and mitotic aberrations were found, among them micronuclei, chromosome bridges and multipolar cells were of significant appearance.
