Abstract: Leafy vegetables are the major dietary source of vitamins, minerals, fibers and bioactive compounds. Due to rapid urbanization and industrialization, an increasing level of heavy metals in vegetables has been noticed in recent years. This study aimed to evaluate the effects of cow manure and ash like materials for reducing arsenic and lead accumulation in three common leafy vegetables. Therefore, a cross-sectional study was conducted on three leafy vegetable samples in Chattogram, Bangladesh. A total of 54 leafy vegetable samples of three species like water spinach, spinach and red amaranth were collected from the six treatment groups which were treated with wood ash, cow manure, charcoal and their mixture and the concentration of arsenic and lead were evaluated by Atomic Absorption Spectrometry (AAS). Results indicated that soil contains a higher level of lead which exceeds the maximum permissible limit followed by WHO. Again, cow manure, wood ash and charcoal significantly reduce the concentration of arsenic and lead in soil. Accumulation of arsenic was significantly reduced by the mixture of cow manure and charcoal in Water Spinach, wood ash and mixture of wood ash and charcoal in Spinach, and wood ash in Red Amaranth. Again, the accumulation of lead was reduced by cow manure, wood ash, charcoal and their mixture, though this reduction was not significant. So, cow manure, wood ash and charcoal have a significant effect on the arsenic accumulation in leafy vegetables because they increase the stability and decrease the mobility of heavy metals in soil.
