In the recent past years, interest in the environmental impact of organotin(IV) compounds has risenmarkedly. Considering that most data in the scientific literature refers to the animal kingdom and notto higher plants cells,we tested the effects of organotin compounds on vascular plant cells, by studyingthe interaction of tributyltin chloride (TBTCl) with Allium cepa, Solanun tuberosum and Solanummelongena, vascular plants that are directly involved in the human food chain. The TBTCl effects onmitotic metaphase plates, on pollen grains and on both microtubers and adult tuber parenchymaticcells were investigated and the concentrations of TBTCl inside the treated parenchymatic cellswere determined through ICP-mass spectrometry. Oxygen and chlorophyll productions were alsodetermined. The obtained results showed that TBTCl influenced not only morphology, but also thephysiology of the vegetable cells since, despite the low concentrations used, the stress the cellswere submitted to was experimentally confirmed. Moreover, the increase in the tin concentration inthe cells, with increasing incubation time, showed that TBTCl possesses a very high capacity to bebioaccumulated and, as a consequence, it is able to enter the food chain.
