Abstract

The neutron activation analysis, gamma coincidence spectroscopy, nondispersive hydrogen flame atomic fluorescence spectroscopy, and Mössbauer spectrometry were used to study the low-selenium environment of the Exi Autonomous Prefecture, a well-known Keshan disease region. The Se contents in the soil samples there range from 0.075-0.18 mg/kg with the average of 0.13 mg/kg, whereas in the maize from 0.001-0.018 mg/kg with the average of 0.0099 mg/kg. The 57Fe Mössbauer spectrum of the soil indicates an anoxic environment. In addition to the FE3+ species the compounds containing low-valence iron e.g., goethite, and so forth, also exist. The rare earth element (REE) pattern obtained by NAA further confirms the reductive soil environment, which causes the selenium deficiency.

Abstract

Trace metals were studied in the sediments of the ecologically, economically and scientifically important estuary of the Acheloos river, in western Greece. Human activities (dams, agriculture, traffic, etc.) influence the estuarine system of Acheloos and in combination with the hydrological, mineralogical and morphological characteristics of the estuary affect the chemical behaviour and the distribution patterns of trace metals in its sediments. The large scale disturbance of the system is imminent in the near future as it is planned to divert approximately 50% of the river water. A study of the distribution patterns of trace metals revealed that in the estuary there are zones with different metal levels. The concentrations of most metals (Al, Fe, Cu, Ni, Zn) are elevated in three of these zones (upstream, sill, seawards). A different behaviour was observed for Mn due to its association with carbonates that were observed in significant concentrations throughout the estuarine zone. A sequential extraction procedure, applied to the sediments, indicated low percentages of easily exchangeable metals, increased mobility of Cu and Zn and increased association of Ni, Cr and Fe with the aluminosilicate lattice. Although the river is not considered to be heavily polluted, some metals have shown an enrichment in the surface sediments as a result of general anthropogenic activities not derived from point sources.

Abstract

Trace element analysis in excavated bones is complicated by the lack of a reliable index for estimating the original amount of bone material. In this study, we subjected modern human bones to alkali treatment to simulate aging. Alkali treatment of vertebrae with attached muscle did not affect sulfur (S) content; it increased the magnesium (Mg), phosphorus (P), and zinc (Zn) contents, and tended to decrease iron (Fe) content of the bones. When vertebrae cleaned of muscle were used, alkali treatment did not affect S and Fe contents but increased Mg, P, Ca, and Zn contents. Ca and S contents were higher in excavated bones (200-1300 yr old) than in their surrounding soils. In contrast, S, Mg, and Ca contents per dry weight did not differ between the excavated bones and the alkali-treated modern bones. These results indicate that S can provide a more accurate index of excavated bones than the often-used Ca content or dry wt measures, especially for bones excavated from calcium-rich soils.

Abstract

A blackish staining found on the crowns of teeth of 51 skulls from the excavation of the medieval St. Olav's church in Trondheim was analyzed using secondary ion mass spectrometry (SIMS) and atomic absorption spectrometry (AAS). In four teeth, mass spectra and step scan concentration profiles of SIMS were performed and compared with the grey scale pattern in photographs of the analyzed paths. The manganese curve showed the highest degree of conformity with the grey scale pattern. The AAS analysis confirmed the increased content of manganese in blackish stained enamel. It was concluded that manganese, probably in the form of an oxide deposited from the soil, was the cause of the blackish staining.

Abstract

The multielement (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, V, Zn) levels in various common vegetables and surface soils collected from two typical growing areas of north-western Greece are presented. The results are representative and indicate metal concentration levels in vegetables grown in Greek areas under similar conditions. The content of the metals is generally at the same levels or even lower than that reported for vegetables consumed in several countries and species grown in other agricultural and industrial Greek areas. Enhanced levels of metals observed in certain vegetable species could be related to their concentration in the corresponding soils. The results of the present study indicate that the mean intake of heavy metals (As, Cd, Pb and Se) by adults due to consumption of vegetables from the two sites, for an average consumption, pattern, generally is well below the allowable daily intakes. On the other hand, the contribution of the vegetables to the recommended amounts of the essential elements (Cu, Fe, Mn and Zn) is satisfactory and higher than previously reported.

Trace element nutrition during pregnancy.

Clin Obstet Gynecol, 1994 Sep, 37:3, 574-86

Abstract

The best means to ensure an optimal intake of trace elements during pregnancy is the consumption of a well-balanced diet that includes both animal- and plant-food sources. Although vegetarian diets provide reasonable sources of trace elements, especially in dried beans and seeds, flesh foods contain higher concentrations of trace elements that are in a more readily absorbable form. Iron is the only trace element for which routine supplementation is recommended. In the United States, the iodine content of the food supply is sufficiently high to make supplementation unnecessary, but use of iodized salt is not contraindicated. There is no need to screen pregnant women routinely for trace element status, except to monitor hemoglobin and hematocrit as an indicator of iron status. The best indicators that a woman's trace element status may be at risk is a history of poor food selections, a clinical disorder that alters trace element use or excretion, or prior residence in a region of the world where the trace element content of the soil is low.

Abstract

Medical geology is the application of trace element geography to epidemiology. This approach is used to compare the geographic distribution of selenium and other trace elements in soil and food with that of high schizophrenia rates in the United States and other countries. Since the comparison is most statistically significant for low selenium, the selenium theory of schizophrenia is evaluated by the principles of environmental epidemiology. Although this examination finds the theory deficient, research questions are generated to test the theory further and to investigate the causes of schizophrenia.

Abstract

Concentrations of the elements Ca, Sr, Mg, Zn and Cu were determined in excavated hair specimens and adherent, most probably soil remains from two sites in Germany. Though soil contamination obviously has occurred, the two groups could be distinguished by differential trace element contents in the hair samples. The trace element concentrations might be interpreted in terms of nutritional intake, the results being corroborated by preceding bone analyses and the different local and social settings. Hair decomposition is discussed.

Abstract

The sources and speciation of trace elements in street and house dusts are reviewed. Soil is a major component of both dusts, but a number of elements are enriched in both materials. These include Pb, Zn, Cu, Cd, As, Sb, Cr, Ca, Na, Au, Cl and Br. They arise from a number of contributing and polluting sources. In the case of house dust, some elements, such as Cu, Co, As, Sb, Zn, Cd, Au, Cl, C and Pb, are produced in the house. There are a number of problems associated with the determination of the speciation of trace elements in dusts. These include the low concentrations of many of the elements, and the interpretation of the results from selective sequential extractions. The mobility and potential availability of the trace elements from dust lies in the order Cd greater than Zn, Pb greater than Mn, Cu greater Fe.

Abstract

Severe goiter, cretinism, and the other iodine deficiency disorders (IDD) have their main cause in the lack of availability of iodine from the soil linked to a severe limitation of food exchanges. Apart from the degrees of severity of the iodine deficiency, the frequencies and symptomatologies of cretinism and the other IDD are influenced by other goitrogenic factors and trace elements. Thiocyanate overload originating from consumption of poorly detoxified cassava is such that this goitrogenic factor aggravates a relative or a severe iodine deficiency. Very recently, a severe selenium deficiency has also been associated with IDD in the human population, whereas in animals, it has been proven to play a role in thyroid function either through a thyroidal or extrathyroidal mechanism. The former involves oxidative damages mediated by free radicals, whereas the latter implies an inhibition of the deiodinase responsible for the utilization of T4 into T3. One concludes that: 1. Goiter has a multifactorial origin; 2. IDD are an important public health problem; and 3. IDD are a good model to study the effects of other trace elements whose actions in many human metabolisms have been somewhat underestimated.

Abstract

Excavated and contemporary bones (rib cortexes) of a mature age (40-60 yr) were analyzed by atomic absorption spectrometry for the concentration of seven elements, including Ca, Cd, Cu, Fe, Mn, Ni, and Pb, with a view to historically evaluating the chemical composition of the bones. Fifty-two well-preserved specimens, obtained from western Japan, were classified into six groups according to Japanese prehistoric and historic eras (Jomon, Yayoi, Kofun, Muromachi, Edo, and Contemporary). Average concentrations of Ca were 0.20-0.33 g/g in the excavated bones and 0.17 g/g in the contemporary bones. Among the trace metals, such as Cu, Fe, Mn, and Pb, which showed remarkably elevated concentrations in the Edo era bones, Cu, Fe, and Mn were found to be strongly associated with soil contamination. Lead levels only slightly increased between the Jomon and Kofun eras, but became abruptly elevated following the Edo era. In contrast, the concentrations of Cd increased abruptly in the Yayoi era to a level with an order of magnitude higher than the Edo era, and they have recently decreased to rather low contemporary levels. This tendency becomes clearer when comparing the molar ratio of trace metals to Ca. The cause of elevated Cd concentrations in early excavated bones is discussed in relation to the mineralization of bones and the surrounding environment.

Abstract

Nineteen elements (Al, B, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Sr, Ti, V and Zn) were analyzed in excavated bone (rib) of the Edo era (a Japanese historical era, 300-120 BP (before present] from different burial conditions in Tokyo, and in contemporary Japanese bone (rib) obtained from autopsy cases. The elemental composition of the excavated bones varied according to their burial conditions. The concentration of soil-related elements such as Fe, Mn, Co and Ti in the bone was lowest in the samples in the "wooden coffin in a stone room", next lowest in the "funeral urn with mud", and highest in the "wooden coffin full of mud". The Pb concentration was higher in excavated bones than in contemporary bones and much higher, by as much as several tens micrograms/g, in the bones in the "wooden coffin in a stone room" and in the "funeral urn with mud". These results strongly support the notion that Japanese in the city of Edo were highly polluted by environmental lead.

Molybdenum: an essential trace element.

Author

Source

Nutr Clin Pract, 1993 Dec, 8:6, 277-81

Abstract

Molybdenum is found in most foods, with legumes, dairy products, and meats being the richest sources. This metal is considered essential because it is part of a complex called molybdenum cofactor that is required for the three mammalian enzymes xanthine oxidase (XO), aldehyde oxidase (AO), and sulfite oxidase (SO). XO participates in the metabolism of purines, AO catalyzes the conversion of aldehydes to acids, and SO is involved in the metabolism of sulfur-containing amino acids. Molybdenum deficiency is not found in free-living humans, but deficiency is reported in a patient receiving prolonged total parenteral nutrition with clinical signs characterized by tachycardia, headache, mental disturbances, and coma. The biochemical abnormalities in this acquired molybdenum deficiency include very low levels of uric acid in serum and urine (low XO activity) and low inorganic sulfate levels in urine (low SO activity). Inborn errors of isolated deficiencies of XO, SO, and molybdenum cofactor are described. Although XO deficiency is relatively benign, patients with isolated deficiencies of SO or molybdenum cofactor exhibit mental retardation, neurologic problems, and ocular lens dislocation. These abnormalities seem to be caused by the toxicity of sulfite and/or inadequate amounts of inorganic sulfate available for the formation of sulfated compounds present in the brain. XO and AO may also participate in the inactivation of some toxic substances, inasmuch as studies suggest that molybdenum deficiency is a factor in the higher incidence of esophageal cancer in populations consuming food grown in molybdenum-poor soil.

Abstract

The hypothesis is presented that deficiencies or excesses in the content or availability of trace elements in rocks and soils, or in water flowing through them, may be a possible cause of certain chronic diseases, including cardiovascular ones. The geographic distribution of cardiovascular diseases is often associated with geochemical differences. This trend is particularly evident in the United States and in Europe, with higher rates for cardiovascular mortality in areas underlain by soils that are poor in most essential trace elements. Confirmation of this trend is found in connection with the degree of mineralization of local water supplies. Areas that are served by soft waters usually show higher rates of cardiovascular mortality and other forms of cardiovascular pathology, compared with the areas that are served by hard waters. Such a negative association between water hardness and cardiovascular pathology is evident in many countries, both industrialized and developing ones.

Abstract

Elemental composition of some Ayurvedic medicinal plants used for healing urinary tract disorders has been studied by nondestructive neutron activation analysis with a 252Cf source and atomic absorption spectroscopy. In total, 14 elements have been estimated in different plants; among these Cu, Cr, Co and Cd are found to be present at the trace level; Mn, Pb, Zn, Ni, Na, Fe and Hg at minor level and K, Ca and Cl at major level. The differences in the concentration of the elements are attributed to soil composition and the climate in which the plant grows. The importance of some elements in diseases related to renal disorders is also briefly discussed.

Abstract

Studies under controlled experimental conditions show a clear advantage for staple food grown under biological/ecological farming conditions as compared to those from conventional farming methods. This is especially true for the vegetative parts of plant products, where lower undesirable (e.g. nitrates) and higher desirable (e.g. vit. C, trace elements) components are present. A better storage quality of plant products (e.g. cabbage, carrots) is also frequently the consequence of biological/ecological farming practices. An overall significantly lower level of residues of agrochemicals has been demonstrated in such products. It is increasingly noticeable, that especially in Central Western Europe, consumers are not exclusively interested in "healthier" food for themselves but also in an healthy environment. This is one of the important reasons, why they are interested in buying food from biological/ecological farming systems and why they are prepared to pay higher prices for such products.

Abstract

Kale, lettuce, carrots and potatoes were grown in 20 experimental plots surrounding a wood preservation factory, to investigate the amount and pathways for plant uptake of arsenic and chromium. Arsenate used in the wood preservation process is converted to the more toxic arsenite by incineration of waste wood and is emitted into the atmosphere. Elevated concentrations of inorganic arsenic and chromium were found both in the test plants and in the soil around the factory. Multivariate statistical analysis of the results indicated that the dominating pathway of arsenic and chromium from the factory to the leafy vegetables grown nearby was by direct atmospheric deposition, while arsenic in the root crops originated from both the soil and the atmosphere. Consumption of vegetables grown near the source would result in an increased intake of inorganic arsenic, but the intake via the total diet was estimated to be below the provisional tolerable daily intake for inorganic arsenic established by FAO/WHO.

Abstract

The deposition of lead was monitored over 8 years in the area around a car battery factory north of Copenhagen, Denmark. The area also has heavy traffic. Deposition was measured by in-situ grown vegetables, transplant grass culture biomonitors, bulk deposition and soil samples. Three impact zones were identified by a multivariate statistical analysis. Within each zone, the total dietary intake of lead was estimated for adults and children as a percentage of the provisional tolerably weekly intake (PTWI), and as a result recommendation on restrictions in use of locally grown fruit and vegetables were given to the public. The pattern of lead deposition in the area during the period 1981-1988 was monitored and the amount of lead ingested via vegetables was toxically evaluated. Lead emission reduction measures introduced in the factory and in the traffic during the period produced significant reductions in lead deposition.
