Evaluation of heavy metal contamination in water, soil and plant around the open landfill site Mogla Bazar in Sylhet, Bangladesh

This study was aimed to determine the heavy metal concentration in water, soil, and plant around an open landfill site in Mogla Bazar, Sylhet, Bangladesh. The concentration of different metals such as iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), lead (Pb), and cadmium (Cd) were analyzed using a Flame Atomic Absorption Spectrophotometer (AAS) with proper digestion method. The mean concentration of heavy metals found in the water samples were in the following order Mn>Fe>Pb>Cu>Zn>Cd. Besides, the trend of trace metals mean concentration order in the soil is Fe>Mn>Pb>Zn>Cu>Cd. Luffaacutangula, Oryza sativa, and Raphanussativus var. longipinnatuswere accumulated a higher concentration of metals which can be associated with adverse health effect in the area. All the metal contents were compared with…
