Instrumental neutron activation analysis of the hair of metallurgical workers

Hair samples were collected from 20 metallurgical workers (10 males and 10 females) and from 59 control subjects (32 males and 27 females), whose jobs do not indicate a specific occupational exposure. The concentrations of ten minor and trace elements (Al, Co, Cu, Fe, Mg, Mn, Sb, Se, V and Zn) were determined by instrumental neutron activation analysis (INAA). The statistical data distributions, the sex and age influences in these elemental concentrations and the average values obtained for the control group were compared with published data. The effect of occupational exposure to the metallic elements was reflected in elemental composition of hair by significant higher concentration levels of Al, Co, Cu, Fe, Mg, Mn, Sb, V and Zn in the hair of the exposed group, when compared with the control group.

Multielement analysis of the hair of mining industry workers

Scalp hair samples were collected from 75 zinc mine workers at the Nakadatsu Mine in Fukui Prefecture and were subjected to instrumental neutron activation analysis for determination of Cu, Cl, Mn, Ca, Au, Br, As, Na, K, Hg, Zn and Co concentrations. For determination of Cd, atomic absorption spectrophotometry was applied to approximately a half of the samples. The results were compared with the data of inhabitants of Suginami Ward in the Tokyo Metropolitan Area. Excessive concentration in the mean values of Zn, Cu, Mn and Hg was observed in the hair of the miners as compared with the Suginami residents. On the other hand, the mean concentrations of K and Cl in the hair of the miners were lower than those of the Suginami inhabitants.     

Determination of trace elements in hair of some local population in Iran by instrumental neutron activation analysis

Scalp hair samples from 100 individual residents in Isfahan, Iran were analyzed for Al, Br, Ca, Cu, Hg, I, K, Mg, Mn, Na, S, V, and Zn by instrumental neutron activation analysis. The results of this investigation show that the ranges of the concentration of trace elements in hair are somewhat wide, for example Mg has the range of 20 to 209 ppm for 100 subjects. The results are compared with the data reported in the literatures. A substantive correspondence between the present data and literature values from different countries, have been observed but they did not show any regular dependence. The level of iodine is significantly different from other countries and is strongly linked to local environmental factors. The correlation coefficient for Al–V, Mn–Al, Ca–Mg, and V–Mg pairs was 0.823, 0.821, 0.830 and 0.746, respectively.

Trace elements in head hair of hemodialysis patients

Instrumental neutron activation analysis /INAA/ was applied to measure trace elements in head hair of 19 patients with impaired renal function /14 males and 5 females/ and of 40 normal individuals /20 males and 20 females/. It was the aim to use head hair as a possible indicator of total body trace elements status and to investigate whether significant changes occur as a result of chronic hemodialysis. The elemental concentrations of 20 elements /i.e. Na, Mg, Al, Cl, K, Ca, V, Mn, Fe, Co, Cu, Zn, As, Se, Br, Ag, Cd, Sb, I and Au/ are presented and compared with published data. The present study revealed that the hair of the dialysis patients contained about ten times more iodine than that of the control group. No significant differences were observed for the other elements measured, except for sodium and antimony.     

Nuclear Activation Methods in the Estimation of Environmental Pollution and the Assessment of the Industrial Plant Impact on the Citizens of Gdansk (Poland)

Neutron Activation Analysis (NAA) is a sensitive analytical technique useful for performing both qualitative and quantitative multi-element analysis of major, minor, and trace elements in samples from almost every conceivable field of scientific or technical interest. The NAA method was applied to estimate the atmospheric air quality assessment based on the analytical investigation of rainwater composition in comparison to a moss biomonitoring study performed in selected urban areas of Gdańsk, Poland, during the half-year of exposure. The main objectives of this project were: comparison of dry and alive moss abilities to bioaccumulate inorganic pollutants; and, detection and identification of natural and anthropogenic pollutant sources in this region. An impact of Gdansk Phosphatic Fertilizer Plant “Fosfory,” Poland, on occupational staff and citizens living near the plant has also been examined. The elements, Al, As, Au, Br, Ca, Cl, Cu, Dy, I, In, K, La, Mg, Mn, Mo, Na, S, Sb, Sm, U, V, and Zn, have been determined by instrumental neutron activation analysis (INAA) in the indoor workplace air; in urine, hair, and toenails collected from workers and persons living in a neighborhood near the plant; and from people from the control group not connected with the plant in any way. Analyses of hair and nails was performed at the Interfaculty Reactor Institute in Delft, The Neatherlands, at a 2MW swimming-pool nuclear reactor and at the Joint Institute for Nuclear Research, Dubna, Russia. The essential differences in concentrations of elements for workers and control group were evaluated using non-parametric Mann-Whitney U-tests. Significant differences between workers/citizens of the factory neighborhood and the control group were found for some elements (i.e., Mg, Sb, S, and V), but in the base of these differences, it is hard to define if the factory impact exists. An impact of Federeal-Mogul BIMET S.A. in Gdansk, the biggest manufacturer of slide bearings in Poland, on occupational staff has been also examined. The concentrations of Cu and Pb are much higher in samples taken from workers then from the control group. These results also indicated that hair and toenail samples are useful in the evaluation of that impact. Workers of the slide bearing factory are occupationally exposed to elements, which can be harmful to their health.     

Multielement neutron activation analysis of human scalp hair a local population survey in the Tokyo metropolitan area

Applying instrumental neutron activation analysis, multielement analysis of human hair was carried out to elucidate the levels of various trace element concentrations in hair of local population in the Tokyo metropolitan area. 202 hair samples were collected from the inhabitants classified by sex and five age groups. Using several combinations of irradiation time, cooling time and counting time, forty elements were quantitatively analyzed. The method of analysis for data including samples under detection limit is discussed, assuming that the frequanecy distribution of trace element contents in hair is log-normal.     

Radioactivation analysis of hair a means of biological monitoring of the environment

Determination of mineral and trace element concentrations in pine needles by ICP-OES: evaluation of different sample pre-treatment methods

In the present study, the determination of mineral and trace elements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, P and Zn) from pine needles using three sample pre-treatment methods followed by inductively coupled plasma optical emission spectrometry, was examined. Sample pre-treatment methods tested were microwave digestion, ultrasound-assisted digestion and dry ashing. The new ultrasound-assisted digestion method was optimised by the analysis of the standard reference material (SRM) 1575a (pine needles) sample. The speed of dry ashing method was significantly increased by ultrasound dissolution after ashing. All the ICP-OES measurements were performed in robust plasma conditions which were tested by measuring the Mg II 280.270 nm/Mg I 285.213 nm line intensity ratios. The microwave digestion resulted generally in slightly higher element concentrations than ultrasound-assisted digestion. B, Cu and Na resulted in such low concentrations that they could not be accurately determined by using the microwave digestion method. The t-tests found no significant differences between the certified and the determined element concentrations of the SRM 1575a using the dry ashing method followed with ultrasound dissolution.     

Interlaboratory study of trace and other elements in the iaea powdered human hair reference material,HH-1

A powdered intercomparison material for trace element studies was prepared from human scalp hair and distributed to more than 100 laboratories of which 66 reported results for altogether more than 40 elements. By statistical evaluation of these data certified concentration values were derived for 20 elements, namely As, Au, Br, Ca, Cd, Cl, Co, Cr, Cu, Fe, Hg, Mg, Mn, Na, Pb, S, Sb, Se, Sr and Zn. The data also made it possible to compare different methods of analysis and to judge the value of different levels of experience on the part of the analyst concerned; these comparisons are presented here with special reference to the elements As, Cd, Hg, Pb and Sb.     

Trace element analysis of human blood serum by neutron activation analysis

An attempt was made to see if there is any correlation between the trace element concentrations in the human blood serum and some specific disease.
