Opis:: Heavy metal compounds are included in many cosmetics and dietary supplements. The most frequent metal contaminants of cosmetic products are mercury, lead, cadmium and arsenic. The contents of toxic metals in cosmetic products are mainly associated with the use of inadequately cleaned raw materials. Despite numerous inspections of the manufacturing process andkeeping the production in line with the principles of Good Manufacturing Practice (GMP), these elements are still found even in products of the best quality. Metals contaminate cosmetics as a result of production processes. Heavy metal toxicity is the result of prolonged exposure which causes the appearance of many side effects. The mechanism of toxicity is mainly related to the impairment of ATP and the change of protein synthesis in enzyme activity, by inducing free radicals. Metals interfere with, among others, the proper functioning of organs, neurotoxic effects, cause problems in learning and behavior, adversely affect the proper functioning of the immune system and adversely affect the developping fetus. Metals have the ability to accumulate in certain organs, primarily in the kidneys and the liver. The European Union does not regulate the limits of metal concentrations in detail, but there is a list of substances prohibited for use in cosmetics in all Member States.

Opis:: Głównymi źródłami zanieczyszczeń powietrza i gleby związkami arsenu jest przemysł wydobywczy węgla kamiennego i paliw płynnych oraz górnictwo i hutnictwo metali nieżelaznych. Na obszarach gdzie przemysł ten jest dobrze rozwinięty obserwuje się przypadki zatruć przewlekłych wśród mieszkańców. Stałe monitorowanie stopnia zanieczyszczenia produktów spożywczych związkami arsenu jest więc koniecznie zwłaszcza w tych rejonach.
The main source of air and soil contamination with arsenic compounds is mining industry of coal and oil as well as mining and metallurgy of non-ferrous metals. The cases of long-drawn arsenism were observed among inhabitants of regions where such industry is well developed. The long term, regular exposure to arsenic compounds both food and inhalation manifests in skin lesion and troubles in functioning of blood, neural and breathing systems. The purpose of this study is the latest literature review concerning contamination of air, soil and potable water with arsenic. The content of arsenic in the comestible produce varies and depends on kind ant origin of the produce. The biggest amount of arsenic in the daily ration came from potable water. The determined amount of arsenic ranged within 1 - 5300 µg/L comes from countries where earth water is used as drinking water, which means that allowable contents specified by FAO/WHO experts is exceeded more than one hundred times. The common inhabitant of developing countries consumes 400 - 650 g of rice weekly. The average contamination of rice with arsenic is 0.57 - 0.69 mg/kg, which means the intake of this element on the level 30% - 45% PTWI (Provisional Tolerable Weekly Intake). The relatively small arsenic contents is characteristic for vegetables and fruits (<0,1 mg/kg), higher amount is observed in leaf vegetables (up to 0.6 mg/kg) and potatoes (0.86 mg/kg). The similarly low arsenic contents (<0.1 mg/kg) is characteristic for the meat produce. Among animal produce the largest quantity of arsenic is determined in fish and seafood (1.5 - 11.2 mg/kg). The introduction of EU regulations in Poland resulted in resignation of the arsenic contents limitation in food, however the continues monitoring of the contamination level with compounds is necessary, particularly in the industrial areas of the country.

Opis:: Oznaczono Cd, Hg, Pb, Cu i Zn w próbkach grzybów jadalnych dziko rosnących pozyskanych w latach 1990-91 z sześciu rejonów Polski.
The amount of lead, cadmium, copper, zinc and mercury has been determined by atomic absorption spectroscopy in 96 samples of edible mushrooms, growing wild fresh edible fungus and dried (Boletus scaber, ceps) mushrooms, acquired from 6 regions in Poland: zielonogórskie, toruńskie, ostrołęckie, radomskie, warszawskie and lubelskie in 1990 and 1991. The level was found to be higher than that allowed by the polish standard PN-89/A-78510 Mushroom Processed Foods. Dried mushrooms and other legal acts eg. Instruction of the Ministry of Health § Social Welfare of 12th November 1990, the content of zinc in dried mushrooms (all samples) and in fresh edible fungus from the zielonogórski and toruński region. The content of copper in fresh edible fungus did not usually correspond with the requirements, whereas in the dried mushrooms (Boletus scaber, ceps) it exceeded the level only insignificantly in individual samples (average from studied regions was found to be within limits). The content of lead in dried mushrooms complied with the requirements of the standard, except for samples of ceps from zielonogórski region, where it insignificantly exceeded the allowed level of 2.0 mg/kg. The average content of zinc and copper in dried mushrooms did not exceed the allowed levels. The levels of mercury determined in the studied samples do not cause any excitement in light of the FAO/WHO agreements. A high level of contamination with cadmium was noted in all studied samples, being 2.5 times higher in edible fungus, 6-8 times higher in Boletus scaber and 19-23 times higher in dried ceps. This fact requires attention of sanitary services, although it should be stated that mushrooms are not the basic nutritional group, and thus their participation in the overall intake of metals in consummated foods is insignificant.
