“…As illustrated in cases from China (Wei et al 2018; Soldatova et al 2018), India (Das et al 1996), Pakistan (Fatmi et al 2013) and Taiwan (Lan et al 2011), residents who use As-contaminated groundwater as drinking water may suffer fatal health consequences due to As exposure.…”

Among the results of community health impact assessments completed in 2014, residents of the Indae abandoned metal mine area showed high average urinary concentrations of harmful arsenic (As), at 148.9 µg/L. The concentration of harmful As was derived as the sum of As(V), As(III), MMA, and DMA concentrations known to be toxic. In this area, mining hazard prevention work was not carried out and the pollution source was neglected, and the health effect of the residents due to arsenic exposure was concerned. We re-assessed As exposure levels and tried to identify exposure factors for residents of this area. Analysis of the soil, sediment, and river water to assess the association between the soil of the Indae abandoned metal mine area and the soil in residential areas confirmed a correlation between Pb and As concentrations in the soil. Since Pb and As behave similarly, the use of the stable Pb isotope ratio for assessment of the pollution source tracking was validated. In the 3-isotope plot (207/206Pb vs. 208/206Pb) of soil samples in this area, a stable Pb isotope ratio was located on the same trend line, which confirmed that the soil in the residential area was within the area of influence of the Indae abandoned metal mine. Therefore, we judged that the pollution source of As was the Indae abandoned metal mine. The results by As species were As (III) 1.45 μg/L, As (V) 0.74 μg/L, monomethylarsonic acid (MMA) 2.43 μg/L, dimethylarsinic acid (DMA) 27.63 μg/L, and arsenobetaine 88.62 μg/L. The urinary harmful As was 31.92 μg/L, much lower than the 148.9 μg/L reported in a 2014 survey, due to the implementation of a multi-regional water supply in November 2014 that restricted As exposure through drinking river water. However, concerns remain over chronic exposure to As because As in river water used for farming and in agricultural soil still exceeds environmental standards; thus, ongoing work to address hazards from former mining areas and continued environmental monitoring is necessary.

Research of migration forms in irrigation water of flooded fields contributes to understanding geochemical barrier formation and functioning. It can improve pollution and nutrification control in the soil-water-plant system since geochemical barriers promote concentrating chemical elements at different depths of a soil cross-section. The research aimed to simulate the aqueous migration of chemical elements and their precipitation in the flooded rice fields’ irrigation water to determine the potential of removing them from the solution at the sorption geochemical barrier. The samples of irrigation water were taken after harvesting in the Poyang Lake basin (China) and analyzed with a standard set of methods for natural water, including ICP-MS and ICP-AES. To assess the migration forms, the HCh software package was used. The thermodynamic values database was supplemented with free energies of formation of metal complexes with fulvic and humic acids for standard conditions. Modeling has shown that most of the considered chemical elements migrate in positively charging simple ions. The main agents of complexation with humic substances are Fe, Ca, and U. Kaolinite potentially precipitates from the irrigation water. Results show that sorption of positively charged simple ions and MoO42− on clay minerals should be under special attention.

“…The non-carcinogenic risk of heavy metals in the seasoning powder was calculated using HQ and HI. HQ and HI are used to characterize the health risk of non-cancer adverse effects (Soldatova et al, 2018). HI is the potential risk of adverse health effect from a mixture of heavy metal in the seasoning powder.…”

Seasoning powders are frequently used to enhance the taste, aroma, color and overall acceptability of food by consumers. Different brands of seasoning powder are frequently consumed without adequate human health risk assessment of the heavy metals constituents in them. This study was conducted to determine the heavy metal concentration in four (4) brands of seasoning powder (SP1, SP2, SP3 and SP4) sold in Port Harcourt, Nigeria. Ten (10) heavy metals (As, Cr, Ni, Pb, Cd, Fe, Co, Cu, Mn and V) were analyzed by standard methods using Flame Atomic Absorption Spectrophotometer (Model: GBC 908PBMT). Human Health Risk Assessment of heavy metals in the seasoning powders, taken in through ingestion route, was evaluated by computing the Estimated Daily Intake (EDI), Hazard Quotient (HQ), Hazard Index (HI) and Cancer Risk (CR) based on adult human model variables provided by United States Environmental Protection Agency (USEPA). The results showed that mean concentration of Pb and Cd were 6.35 ± 1.07 mg/kg and 0.53 ± 0.09 mg/kg respectively which are above the Food and Agricultural Organization (FAO) and World Health Organization (WHO) Maximum Permissible Limit (MPL) of 5.0 mg/kg and 0.3 mg/kg respectively. Concentration of Fe, Co, Cu, Mn, and V were below the MPL and As and Cr were not detected in all the samples assessed.EDI for the measured heavy metals were less than the tolerable limits specified by USEPA. The HQ and HI values were within acceptable range of <1 except for SP2 with HI value of 1.04. The results obtained for CR were above the specified acceptable range of 1.0 x10-6 to1.0 x 10-4. These results suggest possible health concerns associated with the consumption of these seasoning powders in the long term. Strict and systematic surveillance of heavy metals such as Pb and Cd in commonly consumed seasoning powder should be done to ensure safety and quality of the seasoning powders sold in Nigeria. Keywords: Seasoning powder, Heavy metals, Bio-toxicity, Hazard index, Cancer risk.
