Levels of selected heavy metals of Mn, Cd, Pb, Zn, Fe and Co were evaluated in irrigation water, soil and managu (Solanum Nigrum) from Homahills, Homabay County, Kenya. The samples were collected purposively and randomly then transported to KALRO Kericho to be analysed using Inductive Coupled Plasma Optical Emission Spectroscopy. Descriptive statistics and t-test analysis for the heavy metal concentrations were done using SPSS Version 21, transfer factor was also calculated. The levels of heavy metals detected in irrigation water were; 0.

“…This section accounts for the most significant contaminant and illustrates the severity of this pressing environmental problem. www.nature.com/scientificreports www.nature.com/scientificreports/ Among the transition metals accepted as human carcinogens in one form or another 33 , the maximum mean daily dose of Pb (9.18 × 10 −6 mg/kg/d) and Cr (1.42 × 10 −6 mg/kg/d) can be a concern for the drilling crew and environment 34 . The average daily dose of Pb and Cr increased deeper at the subsurface.…”

This study investigates the toxicological effects of heavy metals on lithofacies of the subsurface in a drilled hydrocarbon well as well as, to the drilling crew and people in an environment. the pollution levels of selected heavy metals were considered alongside their ecological effects during dry and wet seasons. the health hazard potential of human exposures to the metals, were estimated in terms of intensity and time using the USepA recommended model. the heavy metal concentration for each layer decreased across the lithofacies as follows; Layer 5> Layer 4> Layer 3> Layer 2> Layer 1. the average concentrations of the heavy metals present in the samples obtained from the formation zone, varied significantly and decreased in the order of Al> Zn> ni> pb> cr> cu> cd> As> Hg. the highest concentration of Al, cu, and Zn in this present study were within the maximum allowable limits whereas, those of As, cd, Hg and ni were all above their maximum allowable limits. Among the transition metals analysed, the maximum mean daily dose of Pb (9.18 × 10 −6 mg/kg/d) and cr (1.42 × 10 −6 mg/kg/d) were confirmed susceptible to human carcinogens and environmental toxins. the estimated hazard quotient shows that the dermal pathway is the most likely route via which the drilling crew and people in the environment can get contaminated. the cancer risk values for the pb (7.72 × 10 −4), Cd (1.35 × 10 −1), Ni (9.97 × 10 −3), As (1.50 × 10 −1) and Cr (3.16 × 10 −3) are all above the acceptable values. the cancer risk contribution for each metal was in the order of As> cd> ni> cr> pb. Layer 5 had the maximum Geo-accumulation index for the heavy metals considered. This higher Geoaccumulation index noted at the depth in Layer 5 may be attributed to the effect of water basin with turbidity currents, deltas, and shallow marine sediment deposits with storm impacted conditions. Also, the pollution from lead (pb) in the dry season was maximum with an i geo value> 5 for all the lithofacies considered because of the low background concentration of the metal. During the wet season, the heavy metal pollution rate was moderate for Zn whereas, it was extremely polluted with respect to pb. The ecological risk potential of Pb shows that the associated ecological risks range from 536-664 in the wet season (i.e. extremely strong) and 2810-3480 in dry season (extremely strong). The high level of Pb pollution found in the area at such shallow depth may be due to the sedimentary folds possibly caused by the full spectrum of metamorphic rocks and primary flow structures at shallow depths. This was used to identify the environmental sensitivities of the heavy metals during the dry and wet seasons.

“…[23] [50]. In the Comas district, the two varieties of native potato showed higher BCF for the five metals, this could probably be due to variations in the physical and chemical properties of the soil, the environmental conditions of each site and the chemical form of the metal that determines the mobilization and transfer of metals[51] [52].…”

Heavy metals are transferred from the abiotic environment to living organisms, accumulate in food, contaminate the food chain, and are an important route of human exposure involving a potential health risk. In this study, the concentrations of heavy metals (Cd, Fe, Pb, Zn and As) in agricultural soils and tubers of Solanum tuberosum spp. andigena (native potato) were evaluated. Also, an assessment of the health risk associated with the daily intake by the local population was performed in the four districts of the department of Junín, between altitudes of 3800 m to 4200 m. The heavy metals concentrations in soils with native potato cultivation followed the following decreasing order of Fe > Zn > Pb > As > Cd, with values below national standards. The heavy metals content in native potatoes was below the limits recommended by international standards with the exception of Pb. The bioconcentration factor (BCF) for the two native potato varieties in decreasing order was Zn > Cd > Pb > As > Fe, all less than 0.5. The estimated daily intake of metals (EDIM) in adults and children through the consumption of native potatoes was higher for Fe and Zn. The threshold carcinogenic risk values (TCR) for As exceeded the safety limits 1 × 10 −4. It is concluded that the residents in the four high Andean localities would be exposed to carcinogenic adverse health effects associated with the intake of native potatoes. It is important to monitor the concentration of As and other heavy metals in the Andean soils and crops in order to implement a soil and crop management program to ensure food quality.
