Microwave digestion for rapid radiostrontium analyses in salmon fishbone

Impact assessment of heavy metals pollution of Vartur lake, Bangalore

“…Moreover, they are safer and simpler and provide more controlled and reproducible conditions than hot plate or block digesters (Nadkarni,1984 andNouri et al, 2007). In this study, heavy metals digestion was done using EPA Method 3015 (Ikem et al, 2003) and involved a high performance microwave assisted digestion Milestone Labstation using a 6 Monobloc Microwave Ethos D Microwave Labstation (Baron et al, 2004) -an automatic user interface system with a direct automatic temperature and pressure control of up to 300°C and 100 Bar respectively under the given power reference.…”

Determination of 90Sr in milk and milk powder in Tehran and estimation of annual effective dose

“…This regulation defines the levels for radionuclides in foods, which are set into power in early case of nuclear emergencies. For these situations, by considering the high allowable concentration limits, a low detection limit is not of first importance in comparison with the analytical time (Baron et al 2004;Chang et al 2004;Horwitz et al 1992;Jassin 2005;Tait et al 1997Tait et al , 1999Lee et al 2002;Mikulaj and Svcc 1993) and fast methods are required, but in the present study, by the aim of the detection of very low background concentrations, it is not necessary to use new methods, which are also very expensive because of the low regeneration of the exchange and affinity resins.…”

“…Therefore, 90 Sr measurement especially in milk has acquired considerable attention in environmental and personal monitoring programs (Alvarez et al 1995;Froidevaux et al 2006Froidevaux et al , 2004Landstetter and Wallner 2006;Mietelski et al 2004;Al-Masri et al 2004). Also, there are a lot of reports, focusing on the methodology of its measurement (Chang et al 2004;Jassin 2005;Lee et al 2002;Baron et al 2004;Horwitz et al 1992;Mikulaj and Svcc 1993;Tait et al 1997). Accordingly, this paper represents the results of radioactivity analysis carried out for 90 Sr in the milk samples consumed in Tehran-Iran followed by the estimation of its annual effective dose, in order to assess of the toxic effects of this radio isotope in the consumers.…”
