AbstractToxic elements like lead and cadmium are considered harmful to human health. These elements do not have any useful function in an organism. They are known only for their negative actions, which can be tolerated by human body only in certain limits. Carrots may absorb these toxic elements from the soil they grow in. The presence of the contaminants depends mainly on the mode and site of cultivation, fertilizer, industrial infrastructure, level of transportation and roads around cultivation site or occurrence of municipal and agricultural waste nearby. The organic food is supposed to be healthier due to, among other things, less content of toxic substances, which results from more sustainable farming. The aim of this research was to determine the content of lead and cadmium in carrots from conventional and organic farming that were available on polish market.The research had been conducted for two years. Both kinds of carrots had been purchased at the same time in different supermarkets in Poland. Altogether, 36 packages, both conventional and organic carrots, were collected. The samples of carrots were dried and then reduced to ashes in 480 °C within few hours. Then the residues were dissolved in 1 M nitric acid and quantitatively transferred to measuring flasks, complemented with deionised water. The content of cadmium and lead was determined by application of electrothermal atomizer (graphite furnace) in iCE 3000 (Thermo Scientific, USA) spectrometer using adequate cathode lamps and Zeeman background correction. Wavelengths for analysis of lead and cadmium were 217 nm and 288.8 nm respectively.The results show that there are statistically significant differences in the average content of lead and cadmium in conventional and organic carrots. The concentrations of lead in conventional and organic carrots were 0.0192 mg kg-1 and 0.0118 mg kg-1 respectively. The concentrations of cadmium in conventional and organic carrots were 0.0050 mg kg-1 and 0.0023 mg kg-1 respectively.The research indicates that toxic elements like Pb and Cd are present in both types of carrots, but their amount is lower than permissible concentrations established by EU ordinance. The conducted experiments also showed that the content of Pb and Cd in organic carrots is lower than in the conventional ones. This may be resulted in the differences in farming.

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.

This study intended to establish if Cd and Pb in the livers and kidneys of bovine and ovine slaughtered in the study area exceeded to concentrations maximum limit proposed by the European Commission (EC) 2006. After digestion of samples, Cadmium and lead concentrations were determined by Graphite Furnace Atomic Absorption Spectrophotometry (GFAAS). The results of our study have shown that lead and cadmium concentrations depend on age and species. The average fresh weight levels of liver and kidneys of bovine animals were about (0.319 mg/kg and 0.337mg/kg) for Cd and (0,502mg/kg and 0.497mg kg) for Pb, while in ovine, mean concentrations in the liver and kidneys were (0,241mg/kg and 0.232 mg/kg) for Cd and (0.259 mg/kg and 0.265 mg/kg) for Pb. Concentrations above the maximum limit proposed by the EC 2006 for Pb and Cd have been detected in some liver and kidney samples from bovine older than 4 years and in ovine over 1 year old .Statistical analysis revealed a very significant (P<0.01) difference in Cd concentrations in the liver and kidneys between age groups and species.

The aim of this study was to determine the levels of metals (Ca, K, Na, Mg) and trace metals (Ni, Fe, Cu, Mn, Zn, Pb, Cd) in two fish species (gilthead bream [Sparus aurata] and sea bass [Dicentrarchus labrax]) collected from fish farms located along the coast of Tenerife Island. Ca, K, Na, Mg, Fe, Cu, Zn, and Mn were measured by flame atomic absorption spectrometry, whereas Pb, Cd, and Ni were determined using graphite furnace atomic absorption spectrometry. Mean Fe, Cu, Mn, and Zn contents were 3.09, 0.59, 0.18, and 8.11 mg/kg (wet weight) in S. aurata and 3.20, 0.76, 0.24, and 10.11 mg/kg (wet weight) in D. labrax, respectively. In D. labrax, Ca, K, Na, and Mg levels were 1,955, 2,787, 699.7, and 279.2 mg/kg (wet weight), respectively; in S. aurata, they were 934.7, 3,515, 532.8, and 262.8 mg/kg (wet weight), respectively. The Pb level in S. aurata was 7.28 ±3.64 μg/kg (wet weight) and, in D. labrax, 4.42 ±1.56 μg/kg (wet weight). Mean Cd concentrations were 3.33 ±3.93 and 1.36 ± 1.53 μg/kg (wet weight) for D. labrax and S. aurata, respectively. All Pb and Cd levels measured were well below the accepted European Commission limits, 300 and 50 μg/kg for lead and cadmium, respectively.

Background: In recent years, the use of tobacco in Indonesia increasingly varied in the forms and methods of consumption, one of which is shisha. Smoking shisha is increasingly popular due to a misperception that smoking shisha is harmless and lack of knowledge about the effects of shisha smoking in oral health.Literature analysis: “PubMed” used as a search tool to identify all empirical studies related to the effects of shisha smoking on health, especially in oral cavity.Discussion: Shisha smoke contained various toxic substances such as Nicotine, Tobacco Specifc Nitrosamines, Polycyclic Aromatic Hydrocarbons, Volatile Organic Compounds, Carbon Monoxide, Tar, and high-temperature metal heating causing shisha smoke contained toxic heavy metals such as arsenic, nickel, cobalt, chromium, lead, and cadmium. The content of these toxic substances showed that smoked shisha is associated with dependence, acute and long-term negative health effects similar to cigarette smoking. Toxic substances may cause various infections of microorganism such as Candida sp, Herpes Simplex Virus (HSV-1), Epstein Barr Virus, Mycobacterium tuberculosis, Human Immunodefciency Virus; Oral mucosal changes such as Hairy Tongue, Smoker’s Melanosis, Nicotine Stomatitis, Frictional Keratosis, Fissured Tongues, gingival or periodontal inflammation, and leukodema; and lead to malignant lesions such as Keratosis, Leukoplakia, Erythroplakia, Oral Submucous Fibrosis and Lichenoid Lesions.Conclusion: Smoking shisha gives bad impact for human health especiallyoral health. Shisha smoking can lead to the development of various infectious diseases and potentially lead to malignancy in the oral mucosa. These foundings breaks the belief that shisha smoking is safe for health.
