چکیده مقاله:

Aluminum is a toxic metal that humans are exposed to in their daily lives at an increasing rate. Aluminum is also widely used in the manufacture of various types of household utensils. The aim of this study was to investigate the effect of water boiled in aluminum containers on cell proliferation and interphase and mitotic phase aberrations in the meristematic cells of onion root using Allium cepa test. Three aluminum container from three different companies were tested. Then water boiled containing concentrations of ۵ and ۱۰ mg / l aluminum was prepared from each container and five onions were tested for each concentration in each container. In order to rooting, the onions are exposed to distilled water for one day and then exposed to the mentioned concentrations of aluminum for ۴۲ to ۴۳ h, and distilled water was used as a control. The results showed that the mitotic index mean at concentration ۵ from container ۱ (P<۰/۰۵) and concentrations ۱۰ from containers ۲ (P<۰/۰۰۱) increased significantly compared to the control. The mean of total aberrations in the mitotic phase, in each of the concentrations of all three container was significantly increased compared to the control (P<۰/۰۵). Also, in all three containers, there was a significant positive correlation between the concentration of aluminum and the total aberrations in the mitotic phase .The mean of total aberrations in interphase, at both concentrations from container ۳, increased significantly compared to control (P<۰/۰۵). Also, in containers ۱ and ۳, there was a significant positive correlation between the concentration of aluminum and the total aberrations in interphase. Considering the potential toxicity of aluminum, these types of containers should be considered as a serious threat to public health.
