Abstract

The study was carried out toassess the concentration of heavy metals in paddy rice grown at farms and parboiled rice sold at Gashua market. Samples were collected using Simple random sampling technique. A total of 120 samples 30 each from farms within Gashua town designated as Gashua North GN, Gashua South GS, Gashua Southeast SE, Gashua South west SW and 30 samples of parboiled rice from Gashua Market GMK were collected. The samples were digested and analyzed using Micro plasma atomic emission spectrometry (MP-AES). Data generated was subjected to one way analysis of variance.The result of the study revealed a significant (P<0.05) difference in heavy metals concentration across all samples. Despite the effect of parboiling; samples from GMK (0.383mg/kg) exhibited the highest Arsenic concentration greatly surpassing WHO/USEPA acceptable limits. Cadmium (0.0242mg/kg) also exceeded the acceptable limit of 0.001mg/kg. Lead concentration from all locations superseded the recommended limit especially from GMK at 0.102mg/kg exceeding the limit of 0.0035mg/kg alsoremarkable increases were seen in chromium. These however call for effective / stringent monitoring and regulation by regulatory authorities coupled with heightened public health awareness by sister agencies in other to curb the menace.
