Electron seed dressing of barley—aspects of its verification

Effect of various parameters on detection of irradiated fish and oregano using the ESR and PSL methods

“…Bortolin et al (2007) reported that the results clearly indicate a marked lightinduced bleaching of the PSL signal of irradiated oregano samples. Eschrig et al (2007) reported that the light exposure can cause rapid fading of the PSL signal of electronically dressed barley seeds.…”

“…Eschrig et al (2007) reported that PSL was able to classify electronically dressed barley seeds after storage times of at least 12-13 months and the upper threshold T 2 = 5000 count/60 s can be well applied while an adjustment could be supported for the lower threshold suggesting an increased lower threshold for barley. Cutrubinis et al (2005) reported that the PSL signals were higher than the upper threshold T 2 even after two months (barley) or 10 months (wheat) of storage.…”

“…The applicability of these methods differs among various foods as a result of different food composition. In addition, other parameters such as the temperature and light conditions as well as the time after irradiation treatment influence their applicability (Bortolin et al, 2007;Cutrubinis, Delincée, Stahl, Roder, & Schaller, 2005;Empis, Silva, Nunes, & Andrade, 1995;Eschrig, Stahl, Delincée, Schaller, & Roder, 2007;Haire et al, 1997;Lea, Dodd, & Swallow, 1988;Malec-Czechowska, Strzelczak, Dancewicz, Stachowicz, & Delincée, 2003;Tabner & Tabner, 1996). The detection limits and sensitivity of ESR method are influenced by the degrees of mineralization and crystallinity of hydroxyapatite in the sample.…”

Die e-ventus Technologie – eine Innovation zur nachhaltigen Reduktion von Pflanzenschutzmitteln mit Empfehlung für Bio-Saatgut

“…Photostimulated luminescence (PSL) has limited use because it can be adversely affected by the effect of visible e-ventus Technologie 115 light. ESR spectroscopy is the most suitable method because reliable detection is possible for the longest period of time (Stahl et al, 2008;Eschrig et al, 2007;.…”

“…Das Verfahren der Photostimulierten Lumineszenz (PSL) ist nur eingeschränkt geeignet, da es durch den Störeinfluss von sichtbarem Licht beeinträchtigt werden kann. Die Verwendung der ESR-Spektroskopie ist das am besten geeignete Verfahren, da hier für den längsten Zeitraum ein sicherer Nachweis möglich ist (Stahl et al, 2008;Eschrig et al, 2007;.…”
