“…The maximum concentrations of Cu, Zn, Pb, and Cd in the studied soils were also higher than those reported by Wang et al 46 around a tungsten–molybdenum mine, although the average concentrations were comparable to or lower than those reported in the tungsten–molybdenum mine. Furthermore, in soils from paddy fields, the average concentrations of Cd reported by Hao et al 47 on a copper mine area and Cui and Du 48 in an abandoned lead–zinc mine were both lower than those observed in the present study. The results suggest that the soil in the study area is under the influence of exogenous heavy metal pollution.…”

Mining activities have increased the accumulation of heavy metals in farmland soil and in food crops. To identify the key soil properties influencing heavy metal bioavailability and accumulation in food crops, 81 crop samples and 81 corresponding agricultural soil samples were collected from rape, wheat, and paddy fields. Heavy metal (copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), iron (Fe), and manganese (Mn)) concentrations in soils and rape, wheat, rice grains were determined using inductively coupled plasma atomic emission spectroscopy, and soil physicochemical properties (pH, organic matter, total nitrogen, total phosphorus, available phosphorus, and available potassium (AK)) were analyzed. Soil extractable metals were extracted using various single extractants (DTPA, EDTA, NH4OAc, NH4NO3, and HCl). The average concentrations of Cu, Zn, Pb, Cd, and Mn in the soil samples all exceeded the local geochemical background value (background values of Cu, Zn, Pb, Cd, and Mn are 43.0, 81.0, 28.5, 0.196, and 616 mg/kg, respectively), and Cd over-standard rate was the highest, at 98%. Furthermore, soil total Cd concentrations (0.1–24.8 mg/kg) of more than 86% of the samples exceeded the soil pollution risk screening value (GB 15618-2018). The sources of Cu, Zn, Pb, Cd, and Mn in soils were mainly associated with mining activities. The key factors influencing heavy metal bioavailability were associated with the types of extractants (complexing agents or neutral salt extractants) and the metals. Cd and Pb concentrations in most wheat and rice grain samples exceeded the maximum allowable Cd and Pb levels in food, respectively, and Cd concentrations in approximately 10% of the rice grain samples exceeded 1.0 mg/kg. Furthermore, rice and wheat grains exhibited higher Cd accumulation capacity than rape grains, and despite the high soil Cd concentrations in the rape fields, the rape grains were safe for consumption. High soil pH and AK restricted Cd and Cu accumulation in wheat grains, respectively. Soil properties seemed to influence heavy metal accumulation in rice grains the most.

“…In addition, as one of the major pollution sources, the mining of non-ferrous mines also released large amounts of Cd into the surrounding soil environment, such as the mining of lead, zinc, arsenic, manganese, antimony, gold, barium, and uranium [18][19][20]. As the major concentration region of non-ferrous production and also the main rice production region, the exploitation of non-ferrous mines in southern China has resulted in a Cd concentration in some rice grain that exceeded the national standard limitation of China (GB 2762-2017) and posed serious potential health risk of local residents [18,21,22]. However, the influence of silver mining on Cd contamination in the soil-rice system has not been reported.…”

Mining activities are one of the main contamination sources of Cd in soil. However, the information about the influence of silver mining on Cd pollution in soil in mining-affected areas is limited. In the present study, sixteen paired soil and rice grain samples were collected from the farmland along the Luxi River nearby a silver mine in Yingtan City, Jiangxi Province, China. The total, bioavailable, and fraction of Cd in soil and Cd content in rice grain were determined by inductively coupled plasma mass spectrometry. The transformation of Cd in the soil–rice system and potential health risk via consumption of these rice grains were also estimated. The results showed that Cd concentration in these paddy soils ranged from 0.21 to 0.48 mg/kg, with the mean Cd concentration (0.36 mg/kg) exceeded the national limitation of China (0.3 mg/kg, GB 15618-2018). Fortunately, all these contaminated paddy soils were just slightly polluted, with the highest single-factor pollution index value of 1.59. The DTPA- and CaCl2-extractable Cd in these paddy soils ranged from 0.16 to 0.22 mg/kg and 0.06 to 0.11 mg/kg, respectively, and the acid-soluble Cd occupied 40.40% to 52.04% of the total Cd, which was the highest among different fractions. The concentration of Cd in rice grain ranged from 0.03 to 0.39 mg/kg, and the mean Cd concentration in rice grain (0.16 mg/kg) was within the national limitation of China (0.2 mg/kg, GB 2762-2017). The bioaccumulation factor of Cd in rice grain ranged from 0.09 to 1.18, and its correlation with various indicators was nonsignificant (p < 0.05). Health risk assessment indicated that the noncarcinogenic risk for local rice consumers was within the acceptable range, but the carcinogenic risk (CR) was ranging from 1.24 × 10−2 to 1.09 × 10−3 and higher than the acceptable range (1.0 × 10−4), indicating that the local rice consumers suffered serious risk for carcinogenic diseases. The results of the present study can provide reference for safety production of rice in silver mining-affected areas.

Bee pollen is a complex natural compound formed by the honey bee when it mixes with pollen, nectar, and bee saliva. It contains wide range elements that have great importance for the human biochemical process. However, when the content of certain minerals in the pollen exceeds the legal limit, it can have a toxic effect on health. The objective of this study aimed to assess and identify the presence of 16 essential (K, P, Ca, Mg, Na, Fe, Si, Mn, Zn, B, Cu, Mo, Ni, Cr, Se, and Co) and 16 non‐essential elements (Al, Be, Ba, As, Cd, Hg, Tl, Li, Sb, U, Pb, Rb, Sr, Cs, Ti and U) in bee pollen samples from different floral sources in Turkey, while also evaluating the non‐carcinogenic risks associated with bee pollen. A melissopalynological investigation was conducted to identify the plant origins of the bee pollen samples. Afterwards, the levels of 32 elements in bee pollen samples were quantified using Inductively Coupled Plasma Mass Spectrometry (ICP‐MS). Finally, calculations were performed to determine the recommended dietary allowance (RDA) %, estimated daily intake (EDI), target hazard quotient (THQ), and hazard index (HI). The bee pollen samples had varying levels of macro, trace, and ultra‐trace elements, with K, P, Ca, Mg, and Na being the most abundant macro elements, and Ti, Ba, Ni, Cr, and V being the least abundant ultra‐trace elements. The RDA % values for essential elements in bee pollen were found to vary, with Cu, Zn, Fe, and Cr being the highest. The results of the THQ and HI calculations showed that consuming bee pollen at recommended rates did not pose a risk to the health of adults or children (THQ <1; HI< 1).
