The levels of forty-three elements were determined in fresh, preserved, and frozen mussels (n = 208) with the purpose of evaluating their contribution to the recommended dietary intake of essential elements and their potential risk to Spanish consumers’ health. We found relevant differences in the element content in relation to the mode of conservation of mussels as well as in relation to their geographical origin, brand, or mode of production. According to our estimates, mussels are important contributors to the intake of most essential elements, contributing almost 70% of daily requirements of Se, 30–35% of Mo, Zn, and Co, and around 15% of Fe. At the same time, the pattern of average consumption of mussels in Spain does not seem to imply an excessive risk associated with any of the 36 toxic elements studied. However, it should be noted that, in the high percentile of consumption the exposure to Cd and As may be high, in particular that associated with the consumption of fresh and/or frozen mussels. According to the results of this study, a moderate consumption of mussels can be recommended as a valuable and safe source of trace elements.

Toxic Risk

Plant-based beverages have been positioned as an alternative to cow's milk. One of the most consumed plant-based beverages are those made with soybeans. Soybean beverages may be an important source of essential elements. However, the soybean plant is exposed to high amounts of contaminants from the soil and the environment, such as toxic metals. For this reason, the objective of this study is to determine the content of potentially toxic elements (PTEs) (Fe, Cu, Cr, Co, Mn, Mo, Zn, B, Ba, Ni , Li, Sr, V, Al, Cd, Pb) in order to evaluate the human exposure and the toxic risk from the consumption of these products. A total of 40 samples of different brands of soybean beverages were analyzed by ICP-OES (inductively coupled plasma - optical emission spectroscopy). The most notable PTEs is Al (3.93 mg/L), followed by Fe (1.91 mg/L) and Ba (0.69 mg/L). Considering a mean consumption of two serving per day (250 mL/serving), soybean beverages would contribute to the dietary intake of essential elements such as Fe and Mn. This consumption would mean considerable percentages of contribution to the maximum intakes of Al and Pb, which do not exceed the maximum values ​​indicated, but in cases of higher consumption these values could be exceeded with the consequent risk to public health.

Bleak Alburnus Alburnus

The utilization of fish bioindicators has become of crucial importance for ecosystem contamination assessment. Bleak (Alburnus alburnus) is a widely distributed epipelagic fish species characterized as very active with fast metabolism which can lead to a high accumulation of pollutants in tissues. Bleak is easy to sample, identify in the field by morphological characteristics, and easy to work within the laboratory. This study deals with the bleak sensitivity in detecting the pressure of the potentially toxic elements (PTEs) in the large lowland Great Morava River. The Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn, and Zn were estimated in whole body composite (wbc) of bleak. The study was conducted at Great Morava River, near the city of Paraćin in Serbia. The highest concentrations of essential elements Zn and Fe were detected. The most toxic elements As and Hg were below detection limits. The metal pollution index (MPI) was 0.39. In large lowland rivers, point sources of pollution such as municipal wastewaters of smaller settlements usually have only local impact due to high dilution by the main watercourse. Since bleak is a site-specific species, results in this study indicated that this stretch of the Great Morava River is slightly affected by PTEs. None of the elements above the maximum permitted concentrations (MPC) in fish meat for use in the human diet, prescribed by the Official Gazette and European Commission Regulation, were not recorded.

Element Concentrations

Optimisation of the concentrations of essential mineral elements in staple grain diet and reduction in non-essential and potentially toxic elements would considerably alleviate mineral malnutrition and improve the health of humans. Here, wheat (Triticum aestivum L.) plants were biofortified with Zn and/or Se to determine the changes across 36 elements in the grain. The element concentrations were determined by multielemental k<sub>0</sub>-instrumental neutron activation analysis (k<sub>0</sub>-INAA). In comparison to grain from non-biofortified plants, Zn fertilisation increased the grain Zn, Ca, and Mo concentrations, whereas the foliar application of Se only increased the grain Se concentrations. Double biofortification (combined Zn fertilisation and foliar Se) was more effective for the increased Se concentrations in the grain, in comparison to the Se-only biofortified plants, with the grain Zn, Ca and Mo concentrations remained at the same levels as those for the Zn-only biofortified plants. Except for Ba, Br and Rb, the concentrations of the elements analysed were below the detection limits. Double biofortification might be a feasible strategy to efficiently coordinate the mineral quality of wheat grain, although the considerable concentrations of other essential and non-essential elements should not be neglected.

A summary of important chemical properties of soil is given and the way in which acid rain may affect these properties is discussed. Acid rain may suppress microbiological decomposition and nitrification processes, thus influencing the nutrient status of soils. It has also been found that soil organic matter is less soluble in more acid solutions. Changed nutrient availability patterns are predicted in a low pH environment and enhanced leaching of essential elements from the soil exchange complex has been observed. Increased solubility of potentially toxic elements such as aluminium may also occur from soils which have been exposed to acidified rainfall.

Potentially toxic elements (PTEs) pollution in the agricultural soil of China, especially in developed regions such as the Yangtze River Delta (YRD) in eastern China, has received increasing attention. However, there are few studies on the long-term assessment of soil pollution by PTEs over large regions. Therefore, in this study, a meta-analysis was conducted to evaluate the current state and temporal trend of PTEs pollution in the agricultural land of the Yangtze River Delta. Based on a review of 118 studies published between 1993 and 2020, the average concentrations of Cd, Hg, As, Pb, Cr, Cu, Zn, and Ni were found to be 0.25 mg kg−1, 0.14 mg kg−1, 8.14 mg kg−1, 32.32 mg kg−1, 68.84 mg kg−1, 32.58 mg kg−1, 92.35 mg kg−1, and 29.30 mg kg−1, respectively. Among these elements, only Cd and Hg showed significant accumulation compared with their background values. The eastern Yangtze River Delta showed a relatively high ecological risk due to intensive industrial activities. The contents of Cd, Pb, and Zn in soil showed an increasing trend from 1993 to 2000 and then showed a decreasing trend. The results obtained from this study will provide guidance for the prevention and control of soil pollution in the Yangtze River Delta.
