It is well-known that melliferous bees are the most sensitive indicators of ecologic conditions of natural environment. Researches in recent years show that bees and bee products can accumulate selectively some heavy metals, radioactive substances, pesticides and other polluters. Scales of heavy metals accumulation on the territory of Ukraine, as toxins of technologic origin unfortunately increase. Environmental pollution by heavy metals leads to their accumulation in plant and animal raw materials and production, consequently their quality decreases. It was proved that apiary accommodation in heavy metal polluted territories leads to their accumulation in pollen, honey bee-comb and wax. But the questions concerning study of peculiarities of sources, ways of pollution and heavy metals content in bee products are not enough lightened, and that was the purpose of our work. Generalized we present in literature information and results of our researches about the use of bees and bee products in quality of bioindicator contamination of environment by heavy metals. Dependence of content of heavy metals is set in the organism of bees in relation intensity of greening to contamination of environment. It is marked on the necessity of lead through of systems research in relation to determination of content of heavy metals in fabrics of bees and bee products with the purpose of search of new methodological approaches for authentication these toxicant of objective environment of contamination and him apimonitoring. Methodological elements of the researches of regularities of heavy metals and lipids content in the tissues of different anatomic sections of the organism and bee products were elaborated.

 The article is devoted to the problem of consequences of anthropogenic environment pollution with heavy metals and their salts. The review presents data on food products that most actively accumulate them. It is shown that edible wild-growing and cultivated mushrooms are classified as such. At the same time, there are no normative documents regulating the maximum permissible values of heavy metals content for wild mushrooms. Herewith, among the wild-growing mushrooms, there are species that are most prone to the heavy metals accumulation. According to the authors, the issue of studying the accumulation of heavy metals by fungi growing near cities with developed industry is relevant. It is required to develop methodological approaches for their detection in wild-growing edible mushrooms and regulatory documents regulating their admission to the retail network.

Abstract Contamination by dangerous heavy metal in the estuarine environment has risen with concern to the safety of coastal fish as seafood. Anthropogenic emission in the coastal areas becomes the primary source of heavy metal pollution in the aquatic environment, which then accumulates in fish species. Therefore, marine fish has a potency to be used as a bioindicator for heavy metals contamination in the coastal environment, since it may vary, as the results of marine hydrodynamics. This research presents seasonal variations (west monsoon, east monsoon, and intermediate monsoon) of heavy metals accumulation in fish from the coastal region of Cirebon, Indonesia. Three types of economic fish (Scatopagus argus, Siganus canaliculatus, and Nibea albifor) were taken, and the heavy metals (Cr, Co, Cu, As, Cd, Hg, and Pb) content were examined by inductively coupled plasma - mass spectrometry (ICP-MS). The results showed a significant difference (p<0.05) of seasonal variation of heavy metals concentration in seawater and sediment. The contamination in seawater was higher during the east monsoon season, while the contamination in sediment was higher during the west monsoon season. The observation was also revealed variation on heavy metals accumulation in fish species. However, this study found no significant correlation (p>0.05) between the concentration of heavy metals in the environment and fish. Consequently, precaution is needed when using fish as a bioindicator for heavy metals contamination in coastal environments.

Heavy metal toxicity can either be acute or chronic effects. Long-term exposure of the body to heavy metal can progressively lead to muscular, physical and neurological degenerative process. In this research, a total of 30 representative chocolate samples were collected from local shops and markets in Lahore. All the samples were analysed to assess the levels of Lead (Pb), Nickel (Ni), Chromium (Cr) and Cadmium (Cd) by using Atomic Absorption Spectrophotometer in Pakistan Council of Scientific and Industrial Research (PCSIR), Lahore. It was observed that the majority of chocolate samples contain heavy metals levels higher than the permissible limits as recommended by Punjab Food Rules (PFR) 2011. The levels of Pb ranged between 0.375 and 3.4 mg/kg with 90% samples having concentrations exceeding PFR allowable limit (0.5 mg/kg). Whereas, Ni concentrations varied from 0.005 to 0.28 mg/kg and 80% samples were above the PFR limit (0.025 mg/kg). Further, Cr levels analysed between 0.005 to 0.28 mg/kg and 53% samples had Cr concentrations higher than PFR limit (0.02 mg/kg). Similarly, Cd levels were observed between 0.50-3.25 mg/kg with 53% samples having Cd concentrations exceeding the PFR limit (1.0 mg/kg). Investigation indicates that the quality of available chocolates is not recommendable for eating because of the higher concentrations of toxic heavy metals.

This paper presents the results of quantitative determination of cadmium and lead in milk, the quality of which is regulated by the Federal Law "Technical Regulations for Milk and Dairy Products" No. 88-FL of 12.06.2008, which indicates permissible levels of toxic substances in milk and basic dairy products. Cadmium and lead, as well as their compounds, are highly toxic substances of cumulative action and pose a serious danger to human and animal health, which makes regular monitoring of the content of these heavy metals in food, in particular milk, relevant. Eight samples of milk sold in the territory of the Chuvash Republic were selected as subjects of the study. Among them are six samples from popular shops of Cheboksara (trademarks “Just”, “Fresh tomorrow”, “From Krasuli”) and two samples of raw cow milk of private farms of Yadrin district (village of Grand Sundyr and village of Persirlana). The analysis of the crude, pasteurized and ultra heat-treated milk of various producers on the content of lead and cadmium at their joint presence was carried out by methods of an inversion voltamperometriya (GOST P 51301-99) and atomic and absorbing spectrometry (MU 01-19/47-11-92 “Methodical instructions by atomic and absorbing methods of definition of toxic elements in foodstuff”) and also in accordance with GOST 26932-96 “By raw materials and foodstuff. Lead Determination Methods” and GOST 26933-86 “Raw Materials and Food Products. Cadmium definition methods”. The minimum lead and cadmium content is found in “Just” brand milk samples of 0.0052±0.0016 and 0.0011±0.0013 mg/kg, respectively. The maximum lead content is found in samples of raw milk of Yadrin district (0.0262±0.0017 mg/kg), and cadmium – in milk of the manufacturer of the trademark “Just” from factory “Semisovsky” (0.0049±0.0007 mg/kg). It has been found that all the samples studied contain a very small amount of heavy metals, which does not exceed the MPC value, which makes it possible to highly assess the quality of milk and dairy products sold in Chuvashia.

The study was carried out to evaluate the heavy metals accumulation in the stems, leaves and roots of Lactuca sativa (Lettuce) and Spinacia oleracea (Spinach). Pot experiment was conducted to examine the phytoextraction ability of these plants for some heavy metals (Cd, Cu, Fe, Pb and Zn) in contaminated soils obtained from an area where indiscriminate burning of waste materials is being carried out beside FCE Katsina. Atomic Absorption Spectrophotometer (AAS) was used for the determination of heavy metals concentrations. The mean levels of metals accumulation evaluated in Lactuca sativa show a higher amount of Fe (47.97 mg/kg) with the lowest amount of Pb (0.44 mg/kg) which follows the order Fe>Zn>Cu>Cd>Pb. Similarly, Spinacia oleracea followed the trend where higher amount of Fe (24.13 mg/kg) with lower Cd (0.25 mg/kg) content was detected, which follows Fe>Zn>Cu>Pb>Cd. The bioaccumulation factor (BAF) was

The aim of the research is to study the intensity of heavy metals accumulation in milk thistle leaf mass under fertilization with the latest types of fertilizers and to assess the environmental safety of such raw materials. Two experiments were laid in the research: the effect of fertilizing milk thistle with organo-mineral fertilizer Growth-concentrate on the intensity heavy metals accumulation by its leaf mass; the effect of fertilizing milk thistle with chelated fertilizers Phosphorus-chelate and Potassium-chelate on the intensity on heavy metals accumulation by the leaf mass. The use of a chelated Phosphorus chelate fertilizer for the fertilization of milk thistle crops leads to a 1.1 times decrease in the contamination of its leaf mass with cadmium and copper in comparison with the option without fertilizing its crops, and the increase in the concentration of lead and zinc compared to the control is insignificant and is within the range errors of experience. The use of fertilization of crops of milk thistle chelated fertilizer Potassium-chelate helps to reduce the contamination of its leaf mass with cadmium compared to the control, and the change in its contamination with copper is within the margin of error. At the same time, replacing the Growth-concentrate fertilizer with Phosphorus-chelate or Potassium-chelate when fertilizing milk thistle crops will lead to a decrease in the contamination of its leaf mass with lead, cadmium and copper, but will increase the contamination with zinc, compared to the control. The most environmentally safe leaf raw material of milk thistle in terms of lead, cadmium and copper content will be observed when fertilizing its crops with chelated fertilizers Phosphorus-chelate, and in terms of zinc content – when fertilizing with organo-mineral fertilizer Growth-concentrate. It is advisable to use Phosphorus-chelate fertilizer for the plant fertilization to reduce the contamination of the leaf mass of the medicinal raw material of milk thistle with heavy metals, in particular cadmium – by 9 % and copper – by 11 %,. To reduce contamination of the leaf mass with zinc by 81 %, it is recommended to use the organic-mineral fertilizer Growth-concentrate. Key words: milk thistle, medicinal raw materials, environmental safety, heavy metals, pollution, fertilizers.
