- Theelementalcontentofrawmaterials，phosphogypsum，substrate(potassiumsalt)，products(superphosphateand“Amofoska”)，soil，andgrasswasdeterminedusingconventionalandepithermaln... The elemental content of raw materials， phosphogypsum， substrate (potassium salt)， products (superphosphate and “Amofoska”)， soil， and grass was determined using conventional and epithermal neutron activation analysis using the IBR-2 pulsed fast reactor at Frank Laboratory of Neutron Physics (FLNP)， Joint Institute for Nuclear Research (JINR)， Dubna， Russia. The analytical procedure was described elsewhere by Frontasyeva and Pavlov [15]. Quality control was based on the application of certified reference materials (CRMs): IAEA-336 (lichens)， IAEA-SDM (lake sediment) and IAEA-SL1 (soil). The certified values and the results obtained by NAA were compared (Table 2). Concentrations of most elements were in good agreement with the CRMs except for Ti， Ni， Ce， Eu， Dy and Rb， which differed from the certified value as follows: Ti - 41.7 %， Ni - 26.5 %， Ce - 24.3 %， Eu - 32.9 % and Dy - 33.3 % in IAEA-SL1 (soil) and Rb - 20.6 % in IAEA-336 (lichens). For the 21 elements in agreement with the certified values the bias observed was below 20 %. For 11 elements (Al， V， Mn， As， Br， Sc， Cr， Sm， Na， Co and Sb)， the bias ranged from 0.03 % to 5 %， for 5 elements (Fe， Zn， Ba， Th and Cs) the bias was greater than 5 % but lower than 10 %， and for 5 elements (La， Tb， Hf， Ta and U) the bias was determined to be between 10 % and 20 %. Samples of raw materials， phosphogypsum， substrate， products， soil (of about 0.1 g)， and grass (0.3 g) were irradiated in cadmium-screened channels 1 and 2 of the pneumatic “Regata” system described elsewhere by Frontasyeva and Pavlov [15]. In order to determine elements associated with long-lived radionuclides， samples were irradiated for 100 hours. Spectra of induced gamma activity were recorded after 4 and 20-24 days of cooling. Short irradiations， 5 minutes for grass samples and 60 seconds for the remaining samples， allowed determination of Al， Ca， Cl， I， K， Na， Mg， Mn， Ti and V. Gamma-ray spectra were recorded after 5 and 12 minutes after irradiation. Data processing was performed using software developed at FLNP JINR [16， 17]. All gamma-spectrometers and counting electronics were made at JINR [16]. The software developed at FLNP JINR for peak searching， peak fitting， and nuclide identification routines were used for processing the amplitude spectra [16]. In the case of the lack of analytical data， there was a half of the detection limit inserted for each analyte [18]. Principal component analysis (classical PCA and fuzzy PCA) was performed as a tool for searching the possible correlations between environmental and industrial samples that could implicate the impact of phosphatic fertilizer production on the environment adjacent to the plant. 請給一個比較能看懂的翻譯，謝謝. 展開
