Heavy Metal Concentration in Some Common Spices Available at Local Market as well as Branded Spicy in Chittagong Metropolitan City, Bangladesh

Abstract

ABSTRACT A study has been conducted to evaluate some heavy metals concentration of spicy from local market of Chittagong metropolitan city, Bangladesh. Total 30 spicy samples of red chili or chili red, coriander, turmeric were collected from five different spots (Khatungonj, Chakbazar, Muradpur, Baluchora, Amanbazar) under Chittagong metropolitan city and metals as Zn, Cu, Cr, Mn, Fe concentration were measured. Metal concentration in red chili, coriander, turmeric were found as increasing order as Cu<Cr<Zn<Mn<Fe, Cu<Cr<Mn<Zn<Fe, Cu<Cr<Mn<Zn<Fe respectively. But the distribution of metal concentration in spicy of Chittagong metropolitan city was varied among the spots. Zn, Cu, Cr, Mn, Fe concentrations among the sampling spots followed the following attenuating order as Chakbazar >Khatungonj >Muradpur >Baluchora >Amanbazar, Khatungonj >Chakbazar >Amanbazar >Muradpur >Baluchora, Khatungonj >Chakbazar >Baluchora >Amanbazar >Muradpur, Khatungonj >Chakbazar >Muradpur >Amanbazar >Baluchora, Khatungonj >Chakbazar > Baluchora >Amanbazar >Muradpur respectively. So, spicy of Khatungonj was the highly contaminated with metal followed by chakbazar spicy and least metal concentrated spicy was in Amanbazar at Chittagong city. According to WHO (World Health Organization), Cr and Fe concentrations exceeded the permissible limit of heavy metals in spicy but other metal concentrations was within tolerable limit. The current research's findings will convey a strong message for the government body, policy maker to establish rules and regulation in order to protect food chain contamination, environment pollution and will be helpful for public awareness. An immediate attention from the concerned authorities is required in order to protect food chain contamination and environment pollution
