“…The violation of the maximum permissible limits of Pb set by the WHO, EU, and US EPA is a cause for public health concern considering the frequency of exposure. The Pb concentration range for the pepper fruit samples in this study is lower than that reported for ginger (22 mg/kg) and in Negro pepper (5 mg/kg) in a study on the heavy metal content of spices in Abuja, Nigeria [23], that reported for leafy vegetables from Kaduna state Nigeria [24] and that reported for beans samples from Italy, Mexico, India, Japan, Ghana and Ivory Coast with a Pb concentration range of 4.084-14.475ppm [25] and homegrown vegetables near a former chemical manufacturing facility in Tarnaveni, Romania [26]. But the results are higher than the values reported for the concentration of Pb in cereals from Kano and Kaduna states, Nigeria [27,28].…”

This study was conducted to determine the heavy metals concentration in pepper fruits cultivated in Katsina state Nigeria. The objectives were mainly to detect the presence of heavy metals in the cultivated pepper fruits in the study area, compare the concentration of heavy metals in samples in relation to the permissible limits specified by WHO/FAO/USEPA Standards. Samples of the pepper fruits were collected in the year 2017 from the selected area. Analysis for the concentration of these heavy metals; Cr, Cd, Fe, Ni, Mn, Pb and Zn was conducted by the use of AAS (by Atomic Absorption Spectrophotometry) method. The health risks to the local inhabitants from the consumption of the samples were evaluated based on the Target Hazard Quotient. The possibility of cancer risks in the samples through intake of carcinogenic heavy metals was estimated using the Incremental Lifetime Cancer Risk. Results from this study has shown that with the exception of the mean values for the heavy metal Pb (1.200-1.333 mg/kg), the mean concentration range (mg/kg) values of Fe (0.901-0.967), Zn (0.899-0.911), Mn (0.250-0.287), Cd (0.053-0.0556) in the samples were generally lower than the USEPA, WHO/FAO maximum permissive limits. With the heavy metals Cr and Ni being below detection level (BDL) The results have indicated that the estimated daily intake (EDI) of the heavy metals were lower than the tolerable daily intake limit set by the USEPA in all the samples. Risk level of Target Hazard Quotient (THQ < 1) was observed for all the evaluated heavy metals for both adults and children. The THQ for the samples were in the decreasing order Mn>Zn>Pb>Fe>Cd, for all the pepper fruits respectively. The sequence of risk was the same for both adults and children although the children had higher THQ values in all cases. ILCR for Cd violated the threshold risk limit (>10−4) and ILCR for Pb reached the moderate risk limit (>10−3) in all the studied samples in adults, While in children ILCR for both Pb and Cd violated the risk. The sampling area trend of risk for developing cancer as a result of consuming the studied samples showed in decreasing order: Funtua senatorial zone > Daura senatorial zone> Katsina senatorial zone for both adult and children. The Cumulative cancer risk (∑ILCR) of all the studied pepper fruits reached the moderate risk limit (>10−3) in adults, while in children it is above the moderate risk limit (>10−2). Among all the studied samples, pepper sample from Funtua senatorial zone has the highest chances of cancer risks (ILCR 6.863273 × 10−3 in adults; ILCR 1.715815 × 10−2 in children) and pepper sample from Katsina senatorial zone has the lowest chances of cancer risk (ILCR 6.260100 × 10−3 in adults; ILCR 1.565025 × 10−2 in children). The study suggests that consumption of the studied pepper fruits in Katsina state is of public health concern as they may contribute to the population cancer burden.

“…But the results are higher than that reported for the concentration of Pb in cereals from Kano and Kaduna states, Nigeria [29,30]. The value was still higher than the range (0.116 to 0.390) reported by Ahmed and Mohammed in Egypt [31] in 2005 and the range (0.007 to 0.032 mg/kg) reported by Okoye et al [32] in a study conducted in South east of Nigeria in 2009 The Pb concentration range for the leaf samples in this study is lower than that reported for leafy vegetables from Kaduna state Nigeria [33] and that reported for beans samples from Italy, Mexico, India, Japan, Ghana and Ivory Coast with a Pb concentration range of 4.084-14.475 ppm [34] and the Pb result for homegrown vegetables near a former chemical manufacturing facility in Tarnaveni and Romania [35]. The concentration of Cd (mg/kg) range from 0.042 to 0.059 in the leaf samples, these values were higher than the range (0.002 to 0.004 mg/kg) reported by Edem et alin Wheat flours in 2009 [36].…”

“…This value is very low when compared with the DPR standard of 36 mg/Kg. Also, in this study, the values were lower than those observed by Mohammed and Folorunsho (2015) in samples within Kaduna metropolitan city, Northern Nigeria. The low level of Zinc metal was not far fetch as there are relatively little activities that could influence the release of Zinc into the environment.…”

The New Calabar River is an important commercial river in Rivers State. Surface sediment samples were collected from four stations and analyzed for some heavy metals concentrations. The results obtained revealed that the concentrations of the metals were iron (Fe) > zinc (Zn) > nickel (Ni) > chromium (Cr) > copper (Cu) > lead (Pb) > cadmium (Cd) > arsenic (As). Their respective mean values were; Fe, 147.84±90.13; Zn, 5.49±2.01; Ni, 3.50±1.48; Cr, 3.42±1.00; Cu, 2.48±1.11; Pb, 2.42±1.09; Cd, 0.089±0.12 and As, 0.006±0.005 mg/Kg. The results were further evaluated with some model indices (contamination factor, ecological risk and enrichment factor assessments. Sediment contamination factor analysis showed that the sediments were slightly contaminated. Ecological risk assessment revealed that the metals at the present concentrations are not harmful or cannot cause risk to the environment. However, enrichment factor analysis indicated that all the metals had significant anthropogenic enrichment at the various stations except As at Aluu, Choba and Iwofe and Cd at Aluu. Therefore, adequate and continuous monitoring should be put in place to prevent upsurge of anthropogenic heavy metals input into the river.
