“…Soil As concentrations (n = 11) were greater than a gastric intubation dose range (>1 mg/kg As), which showed decreased locomotor activity in rats (Pryor et al ), and a soil plant toxicity level (15 mg/kg; n = 10) based on total metal concentrations and growth (Khalid and Tinsley ; Munshower ; Mulvey and Elliott ; Kataba‐Pendias and Pendias ). The Kanab North soil Ag concentrations were greater than effect thresholds for viability of heterotrophic bacteria in culture media (>0.01 mg/L; Albright et al ), which may impede restoration efforts with biocrusts or other sensitive species; however, soil leaching studies would likely be required to assess the exact level of impact (i.e., solubility of As species).…”

High-grade U ore deposits are in various stages of exploitation across the Grand Canyon watershed, yet the effects of U mining on ecological and cultural resources are largely unknown. We characterized the concentrations of Al, As, Bi, Cd, Co, Cu, Fe, Pb, Hg, Mo, Ni, Se, Ag, Tl, Th, U, and Zn, gross alpha and beta activities, and U and Th radioisotopes in soil, vegetation (Hesperostipa comata, Artemisia tridentata, Tamarix chinensis), and rodents (Peromyscus maniculatus, P. boylii) to waste material at the Kanab North mine, a mine with decades-long surficial contamination, and compared the concentrations (P < 0.01) to those at a premining site (Canyon Mine). Rodent tissues were also analyzed for radium-226 and microscopic lesions. Radioactivities and some elemental concentrations (e.g., Co, Pb, U) were greater in the Kanab North mine biological samples than in Canyon Mine biota, indicating a mining-related elemental signature. Mean rodent Ra-226 (111 Bq/kg dry weight [dry wt]) was 3 times greater than expected, indicating radioactive disequilibrium. Multiple soil sample U concentrations exceeded a screening benchmark, growth inhibition thresholds for sensitive plants, and an EC for a soil arthropod. Lesions associated with metals exposure were also observed more frequently in rodents at Kanab North than those at Canyon Mine but could not be definitively attributed to U mining. Our results indicate that Kanab North biota have taken up U mining-related elements owing to chronic exposure to surficial contamination. However, no literature-based effects thresholds for small rodents were exceeded, and only a few soil and vegetation thresholds for sensitive species were exceeded; therefore, adverse effects to biota from U mining-related elements at Kanab North are unlikely despite chronic exposure.

“…A studies stated that Ca2+ and Mg2+ maintain a state of equilibrium in most waters and that high concentration of magnesium in water is believed to have adverse effect on crop yields as the soil becomes more alkaline [41]. Munshower, further stated that value less than 50 is considered to be the acceptable limit for MAR [42]. The value of MAR within the study area ranges from 0.00 to 61.98 with an average of 22.19 see Table 5.…”

“…Some study stated that when the value of SAR > 12 to 15, this could lead to serious physical soil problems that make it difficult for plant to absorb water [42,44]. One of irrigation parameters that help give detailed information on concentration of Na+, Ca2+ and Mg2+ in the water samples is SAR.…”

Groundwater samples were evaluated for irrigation purpose, within selected part of Oju area of Benue State, Nigeria. The study area lies within Asu River Group of the Lower Benue Trough, southern part of Nigeria. Physicochemical parameters were analyzed using APHA, 2012 method. Results from the study showed that pH falls within slightly basic to acidic, with Ec value ranging from 127 to 760 μS/cm, SSP ranges from 1.53 to 43.78, Sodium Percentage ranges from 1.55 to 77.8 %, Kelly Ratio ranges from 0.01 to 0.77, Magnesium Absorption Ratio ranges from 0.00 to 61.98 and total hardness Total Hardness ranges from 72.00 to 425.5 within the study area. The above listed parameters were below various permissible standard value for irrigation except for MAR at LBT/04, Na % at LBT/09, 13 and 14, SAR at 01 and 04 and TH at LBT/04 that were slightly above various permissible standard values. From Gibbs plot it was observed that rock dominance is the major factor that influences groundwater except for few sampling point were precipitation dominance was observed to have influence on groundwater within the study area.
