Abstract
A study has been conducted to evaluate some metal 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 spot (Khatungonj, Chakbazar, Muradpur, Baluchora, Amanbazar) under Chittagong metropolitan city and metal as Zn, Cu, Cr, Mn, Fe concentration was measured. Metal concentration in red chili, coriander, turmeric were found as increasing order as CuKhatungonj>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.
Highlights
A study has been conducted to evaluate some heavy metals concentration of spicy from local market of Chittagong metropolitan city, Bangladesh
Heavy metals are a element with a mass density greater than 4.5g/cm[3 ], the essential metal like Iron, cupper, and zinc are very useful for the growth of the boy but high level are intolerable and mercury, lead, cadmium etc are toxic at very low concentration[7]
The zinc concentration was highest in turmeric as 75.5± 22.23 mg/kg followed by red chili as 72.18±5.9 mg/ kg and lowest in coriander as 68.78±10.32 mg/kg
Summary
A study has been conducted to evaluate some heavy metals concentration of spicy from local market of Chittagong metropolitan city, Bangladesh. Three types of powder spicy samples were collected from local market of Chittagong Metropolitan City of Bangladesh. The zinc concentration was highest in turmeric as 75.5± 22.23 mg/kg followed by red chili as 72.18±5.9 mg/ kg and lowest in coriander as 68.78±10.32 mg/kg. The range of zinc concentration in chili red was found from 83.62 mg/kg (at khatungonj) to 65.48 mg/kg (PRAN brand spicy at Aman Bazar).
