Determinação da fito, cito e genotoxicidade de slime utilizando modelo de raízes Allium cepa L.

Abstract

The slime or amoeba, as it is also called, is a toy that became famous in the 80s. This famous toy has a variety of colors and sizes that attracts the attention of many children and even adults. However, in recent years, both commercial and homemade slime have become a rage among children and teenagers. What is worrying is the incorrect use of these toys, as they can lead to health problems if they are ingested or handled for a long period of time. Within this context, the present work sought to analyze the toxicity in A. cepa roots of a commercial brand slime and of the components used in the manufacture of homemade slime. It was obtained in response to the analyzes that the glue, unlike slime and boric acid, presented phytotoxicity and cytotoxicity due to the drastic reduction of cell division in the roots. Furthermore, the roots that were exposed to boric acid and slime showed prophases to the detriment, characterizing a delay in mitosis induced by these compounds. Although studies show that the components do not present risks related to toxicity, external factors help in their toxic level. Through the analysis of the A. cepa method, it was noted an inhibition of cell division and considerable chromosomal alterations in the cells. Therefore, it is concluded that both compounds tested in the long term or due to the sensitivity to which it is subjected can cause physical damage to health. The bioassay with A. cepa proved to be a useful tool to assess the potential of unregulated substances found in various matrices, such as polyvinyl alcohol present in white glue, as well as other substances.
