食品中锶的原子吸收测定法

锶作为人体必需微量元素,主要来源于食品。据报道,人体每天大约需要从食物中摄取锶2mg左右,锶在人体内的作用主要是组成骨骼,降低心脏病发生率,调节肌肉和神经的兴奋性。近年来研究提示,锶可能与健康长寿有一定关系。而肌体摄入过多的锶又可造成诸如乌罗瓦病、锶佝偻病等中毒性疾患。目前食品中锶测定仅见 ICP法。因此,建立实用的食品中锶测定方法,对于锶的日常检测、研究很与健康关系有一定的积极意义。 1 试验部分1.1 仪器与试剂 GFU-201型原子吸收光谱仪（北京分析仪器厂生产） 锶标准贮备液:1.00mg·ml~(-1),称取高纯碳酸锶0.1693g,加入少量水,缓慢加入硝酸（1+1）10ml,边加边摇至溶解,以水定容至100ml,摇匀。

Sensitive and selective ion exchange-combined atomic absorption: Spectrometric determination of trace elements in rocks

Ion-exchange precipitation was used in geochemical analysis where the various trace elements can be determined by prior separation over an ion-exchange column. By application of the principles of classical wet analysis the presence of trace elements was verified and their quantitative determination performed in rock samples by converting an anion exchanger into the respective ionic forms to obtain the insoluble salts through the action of counterion (an anion) of the resin and the metal ion in the solution. The metal ions are then eluted by suitable eluting reagents that form soluble salts. The columns of 5 g Amberlite IR-400 were used and were converted into the desired anionic forms. The different forms used were sulfide, hydroxyl, carbonate, chromate, and sulfate. Flow rate was maintained at 1 ml/min. Different rock samples were examined for Mn, Zn, Ba, Ni, Cu, and Sr, etc. The results have been compared with the standard results.     

The determination and application of 87Sr/86Sr ratio in verifying geographical origin of wheat

As ⁸⁷Sr/⁸⁶Sr ratio plays a significant role in authenticating the geographical origin of foodstuff, it is important to identify where the ⁸⁷Sr/⁸⁶Sr signature in food comes from, and the methods of ⁸⁷Sr/⁸⁶Sr ratio analysis in food and environmental samples. Wheat with three genotypes, soil and groundwater samples were collected from three regions of China during harvest time of 2014. The ⁸⁷Sr/⁸⁶Sr ratios in the samples were determined by thermal ionization mass spectrometer in order to investigate the possible source of ⁸⁷Sr/⁸⁶Sr in wheat, and the concentrations of Rb and Sr in wheat and soils were also detected by inductively coupled plasma mass spectrometry and combined with ⁸⁷Sr/⁸⁶Sr ratio in order to trace the geographical origin of wheat. The ⁸⁷Sr/⁸⁶Sr ratio, the contents Rb and Sr, and Rb/Sr ratio of wheat and soil samples showed significant differences among three regions. The ⁸⁷Sr/⁸⁶Sr ratios and the concentrations of Rb and Sr in soils were higher than those in corresponding wheat. The ⁸⁷Sr/⁸⁶Sr ratio in wheat was identical to that corresponding soil NH₄NO₃ extracts (labile fraction of soil) and groundwater. Wheat uptake more Rb than Sr. 3D distribution of ⁸⁷Sr/⁸⁶Sr, Rb and Sr could identify wheat samples from different regions clearly. The ⁸⁷Sr/⁸⁶Sr ratio of wheat reflects the ⁸⁷Sr/⁸⁶Sr ratio of the associated environment including soil and groundwater. It is expected that the use the parameters of ⁸⁷Sr/⁸⁶Sr ratio, the contents of Rb and Sr will allow to trace geographical origin of wheat. Copyright © 2017 John Wiley & Sons, Ltd.

Study of transfer of trace elements from soil to medicinal plants in the environment of Mangalore

The concentration of five trace elements Cr, As, Pb, Rb and Sr in seven medicinal plants Garcinia indica, Ficus benghalensis, Flacartia Montana, Nyctanthes arbor-tristis, Morinda citrifolia, Ficus recemosa, Barringtonia acutangula and associated soils were analyzed using ICP-MS. In plant the elemental concentrations of Cr, Pb, Rb and Sr vary widely and in soil the elemental concentrations of Cr, As and Sr showed wide variation. Selective enrichment of elements Rb and Sr was observed in some plants. The soil to plant transfer ratio was significant for Sr. The results of these systematic investigations are presented and discussed in this paper.     

Comparative study of heavy metal and trace element accumulation in edible tissues of farmed and wild rainbow trout (Oncorhynchus mykiss) using ICP-OES technique

The objective of this research was to determine the differences between farmed and wild rainbow trout in terms of heavy metal and trace element accumulation in edible tissues. The samples were analyzed for As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se, Sr and Zn by inductively coupled plasma-optical emission spectrometry (ICP-OES); and for Hg by cold vapor atomic absorption spectrometry (CVAAS). The results were expressed as μg/g of dry weight. With the exception of Ba and Sr, liver had significantly higher heavy metal and trace element concentrations compared to the muscle in farmed or wild fish. Higher levels of Ba, Cr, Fe, Mn and Zn, as well as lower levels of Cu and Sr were found in tissues of wild rainbow trout compared to its farmed relative. Levels of Cd in 41.6% of farmed fish samples and 45.8% of wild fish samples exceeded the European Commission regulation. Regarding the Pb, concentrations in 50% of farmed fish samples and 62.5% of wild ones were above the European Commission limit. However, levels of Hg and As in all of the examined samples were lower than the legislated limits. The differences in heavy metal and trace element accumulation observed between farmed and wild fish were probably related to the differences in their environmental conditions and dietary element concentrations.
