Element Study

A trace element study was carried out on 71 well-drained Podzol soil profiles from the Bathurst region of northeastern New Brunswick. Of these profiles 18 were selected from soils located above sulphide deposits; the other 53 were chosen randomly from areas not underlaid by sulphide-rich rocks. Lead, copper, zinc, iron, manganese, arsenic, antimony, silver, and tin were the elements studied.Lead, silver, and manganese showed definite tendencies to accumulate in the surface L–H horizons. Tin was the only element to consistently show concentrations in the Ae horizons. Arsenic, iron, and lead have accumulated in the B horizons of most profiles. The mean amounts of trace elements for all horizons of the profiles overlying sulphide deposits were higher than similar mean values for profiles above non-mineralized bedrock.

Major and trace elements (Al, As, Ba, Ca, Cd Co, Cr Cs, Cu Eu Fe, Hf, K, La, Lu, Mg, Mn, Na, Ni, Pb, Rb, Sb, Sc, Si, Sm, Sr, Ta, Tb, Th, Ti, U, V, Yb and Zn) in forest soils from three acid-deposition-affected locations in southern Quebec were investigated. Total element concentrations in the surface layer (0–20 cm) of the Podzolic soils were mostly well within the range of element concentrations in Podzols reported worldwide but showed higher mean values for most elements. The mean concentrations of elements (except Zn, at 124 μg g−1) were also generally comparable to the respective elemental baseline data established for Canadian soils. Element concentrations (μg g−1) of Cs (6.2) Sc (19 8) V (106) Rb (194) K (26 500) and Al (76 900) in the surface soils were significantly higher at the 940-m elevation than the concentrations from the sites at 650 and 770 m along the Roundtop Mountain slope, but Ca (1120) and Ni (4.4) were lowest at the 940-m elevation A similar trend with elevation was not observed at the other mountain location (White Peak). Enrichment-factor (EF) analysis showed significant element enrichment (EF ≥ 10) for Cd, Rb and Sb but impoverishment (EF ≤ 0.1) for Ca, Cu and Ni in topsoils.

Crustaceans are known for their trace element bioaccumulation abilities. Muscle tissues of lagoon crab, marine crab, pink shrimp and mantis shrimp marketed for consumption in Nigeria were analyzed for Mn, Fe, Cu, Zn, Hg and Cr levels using standard methods. Muscle levels in mg kg-1 of Mn (0.03±0.00 in lagoon crab), Fe (0.072±0.01 in mantis shrimp), Cu (0.344±0.01 in lagoon crab) and Zn (0.073±0.00 in mantis shrimp) were significantly different (p<0.05) from their corresponding values in other examined crustaceans. The mean values of Cr and Hg were not significantly different across samples. The estimated daily intake of trace element (mg person-1day-1) revealed that Hg (0.000001) in marine crab contributed the lowest daily intake while Zn (0.000226) in lagoon crab contributed the highest daily intake. Total hazard quotient (THQ) values for the trace elements followed descending order of Hg > Cu > Zn > Fe > Mn > Cr. Lagoon crab showed the highest total hazard index among the organisms with 44.80 %, while the least was observed in mantis shrimp with 13.30 %. It is concluded that, as far as human health is concerned, the mean elemental levels in the muscle tissues of the organisms examined pose no danger (THQ < 1).

<p style="text-align: justify;">This paper describes the determination of iron, copper, manganese and zinc in the soils, grapes and wines of the three viticultural regions of the Azores. Iron, copper and zinc were determined by flame atomic absorption spectrometry and manganese by graphite furnace atomic absorption. The concentrations of the four elements differed in soils of the three regions; there was no difference in the concentration in grapes, whereas significant differences were observed for the wines as regards the amounts of iron, manganese and zinc. The concentrations of these four elements in wine correspond with the mean values observed for other European regions.</p>

Nowadays, organic forms of trace elements, which have a high bioavailability, and, as a consequence, have a beneficial effect on the body of animals and birds, are increasingly used in feeding. In this area, quite a lot of research has been carried out on the use of chelates in poultry feeding, but mainly for broiler chickens and laying hens. Therefore, the purpose of our study was the use of organic forms of trace elements such as iron, manganese, copper, zinc, and selenium in the diets of rearing stock of the parent flock of the ROSS cross. The experiment was carried out in the production conditions of the Novosafonovskaya poultry farm of Kuzbasskiy Broiler LLC and at the Small animal science department of the Altai State Agrarian University in 2020. The results of the experiment indicate that replacing 50% of the need for inorganic forms of iron, manganese, copper, zinc and selenium with organic analogs contributed to an increase in live weight, absolute and average daily gains of rearing stock. There was an increase in the uniformity of the flock in terms of live weight, both males and females. The crop percent of poultry in the experimental group was 3.2-4.6% higher due to a decrease not only in mortality, but also in culled chickens.

The purpose of our research was to determine the effect two different complexes of elements of copper, zinc, iron, manganese, selenium by organic and mineral origin in feeding mixture “SK-4” on growing pigs productivity, metabolic state and mineral deposition in their organs. We formed two groups of growing pigs, 40 heads each, with an average live weight of 13.6 kg at the age of 42 days. In addition to the main diet, the experimental animals were fed by two premixes of enriched mineral (in the form of sulfates) and organic (as chelates) complex of trace elements. In growing period, the pigs from control and experimental groups were kept in equal conditions. Within 56 days of experiments the productivity of animals was depended on feeding, whereas the use of organic complex increased the average daily live weight gain by 6.3% (p≤0.01) with simultaneous decrease in exchange of energy costs by 6.4%. In the experimental group, the feeding with organic form of trace elements contributed to the increase in blood: erythrocytes - by 4.8% (p≤0.01) and hemoglobin - by 15% (p≤0.001) during the whole research period. We proved that the addition of chelate forms to the diet of growing pigs provided greater deposition of trace elements in their organs, which allowed reducing the excretion of trace elements, which is confirmed by the changes in histological sections. The results of our study showed that organic elements were more effective in terms of pigs production and health, and fully meet their needs in essential elements.

In this study, effects of age and breed on the trace elements content in different muscles (M. longissimus dorsi, M. longissimus thoracis, M. psoas major, M. intercostalis internus, M. semispinalis capitis, M. biceps femoris, M. biceps brachii) and edible offal (liver, kidney, heart) of cattle were investigated. Iron (Fe), zinc (Zn), copper (Cu), lead (Pb) and cadmium (Cd)contents of muscles and edible offal were determined by inductively coupled plasma-optic emission spectrometry (ICP-OES).According to the results obtained in this study, the content of Cu in M. longissimus dorsi of Eastern Anatolian Red (EAR) breed cattle was higher than Brown Swiss (BS) breed cattle, and the content of Cu in M. longissimus dorsi was statistically significant among the breeds (p<0.05). On the other hand, the highest Cu content in kidney and the highest Cd content in liver were observed the 4-year-old cattle, and the content of Cu in kidney and the content of Cd in the liver were statistically significant among the ages (p <0,05). Besides, the highest contents of Fe, Cu and Cd were found in the edible offal of EAR breed cattle aged 4 years. The mean values of the trace elements found in cattle muscles were ranked as Zn>Cu>Fe>Pb>Cd, whereas the mean values of the trace elements found in edible offal of cattle were ranked as Cu>Fe>Zn>Pb>Cd. Our results suggest that trace element content may vary in both muscles and offal depend on the breed and age of the cattle.Asian J. Med. Biol. Res. June 2018, 4(2): 157-163

Edible vegetable oil samples purchased in Akure, Nigeria, were subjected to physicochemical properties and trace metals analysis. The physiochemical parameters such as acid value, iodine value and saponification value were carried out by standard methods and the levels of the trace metals (copper, zinc, iron, manganese, cadmium, nickel, lead and chromium) were determined by the atomic absorption spectrophotometric method after wet digestion. The range of mean values obtained for the physicochemical parameters of the oils:  acid value (3.59 - 9.65 mg KOH/g); iodine value (32.99 - 75.04 g I2/100g); and saponification value (187 – 207 mg/KOH/g), were within acceptable values for edible oils. The trace metals in the samples were in the range of values (mg/kg):0.10 - 0.60 (Cu); 0.07 - 2.49 (Zn); 0.13 - 0.55 (Fe); 0.01 - 0.48 (Mn); 0.01 - 0.09 (Cd); 0.01 - 0.08 (Ni); 0.07 - 0.26 (Pb); and 0.01 - 0.07(Cr). The concentration of trace metals such as Pb and Cd in the edible oils were beyond established permissible levels.

We made a comparative study of the trace elements in the oral mucosa of 22 patients with oral lichen planus (OLP) and of 100 healthy persons by the PIXE method. Samples were excised from the oral mucosa of the OLP patients (OLP group) and from the buccal mucosa of healthy persons (control group). The results were as follows: Seventeen trace elements and 11 contaminating elements were detected in those oral mucosae. Al , Ti and Pb , which are contaminating elements, were detected in more than 65% of samples from both groups. The mean values of Se and Rb were significantly lower in the OLP group than in the control group. The mean values of the other elements did not differ significantly between the groups. As for the females over 30 years old, the OLP group showed significantly higher values of Zn and Sr than the control group. Their mean values of the other essential and contaminating elements did not differ significantly between the groups, although there was a trend toward higher values in the OLP group. We found by the PIXE method that Zn , Fe and Pd , which are d-transitional elements considered to cause allergic reaction, showed higher values in the oral mucosae of the OLP patients than in those of the healthy persons.

In an excursion in the provinces of Nova Scotia and New Brunswick in August and September 1847, 1 took with me some magnetical instruments, with which I made a few observations for determining the magnetic intensity. The observations were of two kinds; those for the relative total force, made with a pair of Lloyd needles, which I shall designate L(1) and L(2), and an inclination circle, seven inches in diameter, with two verniers reading to single minutes, constructed by Barrow, successor to Robinson; and those for the absolute horizontal force, made with a unifilar magnetometer by Jones. The positions of the needles in the inclination circle are determined by two reading microscopes with micrometer scales. The unifilar has a theodolite base and circle of six inches, divided on silver, and reading to twenty seconds. Both instruments are described in Captain Riddell’s “Supplement” to his “Magnetical Instructions.” Observations to determine the temperature coefficients of the Lloyd needles were made in a small building fastened with nothing but copper, and containing a copper stove. For the weights sent by the maker with these needles, which were inconvenient, I substituted two platinum weights, which have never been removed from the holes in which they were placed before my observations commenced. Using t, t', v, v', θ, θ', φ, φ' for the temperatures, the angles of deflection, the inclinations, and the relative forces, respectively, at low and high temperatures, the following Table exhibits the observations and results by the well-known formula φ = Cos v /Sin ( θ + v ). I find the results the same whether the mean values of t , v , and θ , &c. are used to obtain φ and φ' , or a mean of the daily results is taken.
