“…The contribution of 4 vegetables to the total exposure to heavy metals in the scenarios I, II and III were respectively 40.4%, 68.6% and 90.8% in case of cadmium, and 17.5%, 42.1% and 75.8% in case of lead. The potential health risk due to food consumption contaminated by Cd and Pb were discussed also in studies carried out in the other regions of the world polluted with heavy metals (Zheng et al, 2007;Bian et al, 2015).…”

“…Some heavy metals, such as lead (Pb), cadmium (Cd), chromium (Cr), mercury (Hg), and arsenic (As) are poisonous for plants, animals, and humans, by altering their metabolism, inhibiting growth, and decreasing the production (Das et al, 1997;Nagajyoti et al, 2010;Singh et al, 2013). Despite current international efforts to effectively decrease the increasing ratios of atmospheric pollution, most natural terrestrial ecosystems are still considered at risk because of the long-term high-intensity atmospheric heavy metal deposition and pollution (Shanker et al, 2005;Bacardit and Camarero, 2009;Luo et al, 2013;Bian et al, 2015).…”

h i g h l i g h t sInvestigating heavy metal deposition through rainfall in Chinese natural ecosystem. Precipitation, vehicles number, energy consumption affect heavy metal deposition. Wet heavy metals deposition was positive correlated with soil metals contents. Increasing heavy metals deposition have adverse effects on natural ecosystem. a r t i c l e i n f o a b s t r a c tIndustrialization and urbanization have led to increasingly serious levels of atmospheric heavy metal pollution, which is one of the main sources of heavy metals to terrestrial ecosystems. Therefore, it is essential to quantify atmospheric fluxes and explore their potential effects on natural ecosystems and human welfare. We monitored water-soluble heavy metals (lead (Pb), cadmium (Cd), and chromium (Cr)) in rainfalls on a monthly basis in 2013 and 2014, at 31 field stations located in typical natural Chinese ecosystems. The average soluble Pb, Cd, and Cr deposition was 1.90 ± 1.54, 0.28 ± 0.25, and 0.96 ± 0.48 mg m À2 yr À1, respectively, with a large variation among the different sites. Generally, the atmospheric deposition of soluble Pb, Cd, and Cr was higher in the southwest, central, south, and north China than in the northwest and northeast China, Inner Mongolia, and Qinghai-Tibet. As expected, the atmospheric heavy soluble metal deposition fluxes were significantly correlated with the number of vehicles (Ps < 0.1). The wet deposition of soluble Pb and Cr was positively correlated with oil and coal consumption, unlike Cd deposition. Moreover, soluble Pb and Cd in atmospheric wet deposition were positively correlated with the contents of Pb and Cd in soil at different regions. In this study, atmospheric heavy metal deposition through rainfall in typical natural ecosystems in China is assessed at the national scale, alerting potential ecological hazards resulting from an increasing atmospheric heavy metal deposition and providing a basis for future studies.

“…В настоящее время одной из актуальных проблем является загрязнение окружающей среды и пищевых продуктов тяжелыми металлами [1][2][3][4][5], определение которых, согласно нормативным документам, проводится различными инструментальными методами, такими как вольтамперометрия, инверсионная потенциометрия, спектрофотометрия, атомно-абсорбционная и атомно-эмиссионная спектроскопия, а также масс-спектроскопия [6][7][8]. Все эти методы предполагают пробоподготовку с переведением исследуемых элементов в растворимую форму [9] с использованием способов сухой или мокрой (кислотной) минерализации [12].…”

The actual problem of food chemistry is the contamination of food raw materials and food products with heavy metals. Modern physico-chemical methods for the quantification of heavy metals are highly accurate and allow even trace amounts of elements to be determined, but the complexity of the sample preparation procedure is one of the most time-consuming steps, requiring high costs of reagents and time, especially for analysis of fat-containing samples. In this regard, development of new ways of determination of content of heavy metals in olive raw materials is relevant. Sunflower seeds in which they established the maintenance of toxic elements with use of different ways of sample preparation have acted as an object of a research: dry combustion and a wet mineralization and the developed new way of a fractional mineralization which distinctive features are: preliminary decomposition of test on fatty (oil) and fat-free (oilcake) of fraction with their independent mineralization. Oilcake is exposed to combustion at the maximum temperature 400 ?С for two full cycles, with convertion of the mineralizat in background solution and definition of metals by AAS-ETA method, oil – is dissolved in bipolar solvent in the ratio 1:6:2 from the mass of oil, with the subsequent direct input of mix in an analytical cell of the graphite tubular furnace of an electrothermal atomizer where there is a mineralization and simultaneous atomization of test. The use of fractional mineralization makes it possible to improve the metrological characteristics of the atomic absorption method of sunflower seeds: to increase the average openability of the investigated elements to 90.8%, to reduce the error of convergence (by 4.5%) and the reproducibility (by 4.9%) of the results of the study of cadmium and lead, and also to reduce the total time of sample preparation for 4–6 hours as compared with the test methods.
