“…68, 0.67-16.83, 9.01-43.675, 1.75-38.08 and 0.17-20.80mg/kg of Cd, Cr, Cu, Pb and Zn respectively. These findings are in contrast with those reported by Adam et al (2022), where Pb and Cd were below the detection threshold, and Cu and Zn ranged from 0.023 to 0.039 and 0.003 to 0.042 mg/kg, respectively. Wei et al (2023) also reported heavy metal concentrations in rice to be generally lower than the results in this study (0.068 and 0.121 mg/kg for Cd and Cr respectively).…”

This study investigated the level of heavy metals (Cd, Cr, Cu, Fe, Pb and Zn) in grains sold in Central and Muda Lawal markets in Bauchi. Our objectives include assessing heavy metal concentrations in the grains and evaluating associated health risks. We utilized Atomic Absorption Spectrophotometry following acid digestion of grains to determine heavy metal concentrations. In Central market-sourced crops, the mean concentrations of Cd, Cr, Cu, Fe, Pb, and Zn were 0.06, 0.49, 0.21, 1.16, 0.15, and 0.17mg/kg respectively. Meanwhile, crops from Muda Lawal market exhibited mean concentrations of 0.06, 0.58, 0.17, 1.62, 0.1, and 0.22 mg/kg for Cd, Cr, Cu, Fe, Pb, and Zn, respectively. Cd, Cr, Cu, Pb, and Zn levels were below the permissible limits. However, Fe exceeded permissible limits in small beans, Syria maize, and white guinea corn from Central market, as well as in Syria maize, Pearl millet II, and white guinea corn from Muda Lawal market. The daily intake of Cd, Cu, and Pb from most studied crops exceeded the oral reference dose, posing potential health risks. Conversely, Cr, Fe, and Zn intake levels were within acceptable limits, posing minimal health risks. Hazard quotient and hazard index values were below 1, suggesting that crop consumption is unlikely to pose health risks.

“…As, Cd, Cu and Pb are notable heavy metals of public safety concerns. A study at Aboabo market, Tamale, Ghana revealed detectable levels of some heavy metals (Cu, Zn, As and Pb) and potential health concerns over As pollution in rice (Adam et al 2022). A study in Nigeria also informed of potential health effects to consumers from Pb and Cd pollution in rice (Ihedioha et al 2016).…”

“…Due to environmental contamination and agricultural practices, these elements can nd their way into rice crops, particularly in regions where pollution is prevalent. Their presence in rice raises serious concerns as they are known to be toxic even at very low concentrations, and their long-term consumption can lead to detrimental health effects, including organ damage and increased risk of cancer (Adam et al 2022).…”

This present study investigated the presence, levels and health impact of some trace elements in rice sold on some Ghanaian markets using an inductively coupled plasma mass spectrometry (ICP-MS). A qualitative scan and a further quantification with the ICP-MS revealed the following elements; boron (B), phosphorous (P), calcium (Ca), iron (Fe), zinc (Zn), nickel (Ni), sodium (Na), molybdenum (Mo), silicon (Si), copper (Cu), sulphur (S), cobalt (Co), potassium (K), lithium (Li), manganese (Mn), magnesium (Mg), chromium (Cr), Silver (Ag), beryllium (Be), aluminium (Al), strontium (Sr), tin (Sn), antimony (Sb), lead (Pb), titanium (Ti), vanadium (V), yttrium (Y), zirconium (Zr), barium (Ba), bismuth (Bi), arsenic (As) and cadmium (Cd). The concentration of essential and non-essential metals follows the order: S > K > P > Mg > Ca > Si > Na > Zn > Mn > Fe > Cu > B > Mo > Ni > Co > Li and Al > Bi > (Sn and As ) > Ba > Sb > Sr > Be > Ti = V > Pb > Cd > Zr > Ag > Y respectively. The results showed that rice on sale on the Ghanaian markets are rich sources of S, K, Mg and Ca with moderate levels of essential minerals like Fe, Mn, Zn and Cu. The health impact assessment revealed that As, Sb and P all recorded hazard quotients greater than one. This implies that As, Sb and P could accumulate and adversely affect the health of Ghanaian adolescents, adults and the aged. The likely cancer risk (LCR) estimated from this study revealed that in children, adolescents, adults and the aged, As, Pb, Ni and Cd could individually and in combined accumulated concentrations induce carcinogenicity to consumers in Ghana overtime since the LCR and Total Likely Cancer Risk (TLCR) all exceeded the maximum safe limit of 1×10− 4.

“…However, the greatest source of exposure to heavy metals is through diet [ 8 ]. Several researchers have determined the levels of heavy metals food sources such as fishes [ 10 , 11 ], rice grains [ [12] , [13] , [14] , [15] ], yam [ 16 , 17 ], canned fruits, vegetables [ [18] , [19] , [20] ] and meat products [ [21] , [22] , [23] , [24] ]. According to Makay et al [ 6 ], heavy metals are highly stable and cannot be broken down during the processing of meat, and eventually bio-accumulates in the human tissues after consumption of the product.…”
