No significant antioxidant depletion was measured when [PM.sub.10] samples were incubated with
DTPA. This demonstrates that PM catalytic metal content explained much of the intrinsic capacity of these samples to catalyze damaging oxidation reactions.
Calismaya dahil edilme kriterleri; obstruksiyon sebebiyle USG'de veya IVP'de grade 2 ve uzerinde hidronefroz saptanmasi, ve diuretikli bobrek
DTPA sintigrafide bobrek fonksiyon kaybinin tespit edilmesiydi.
There was a strong relationship between carbonate bound Mn and
DTPA Mn (r=0.883**, Table 6) and exchangeable Mn (r=0.895**), suggesting that carbonate bound Mn might be an important source of plant-available Mn.
Determinaram-se os teores de Mn e Zn extraidos com
DTPA pH 7,3 (Abreu et al., 2001), com Ca[Cl.sub.2] 0,01 mol [L.sup.-1] (Brun et al., 1998) e com Mehlich III (Mehlich, 1984); o Mn e o Zn totais foram definidos segundo o metodo da US-EPA 3052, com digestao em forno de microondas com HN[O.sub.3] + HF + agua deionizada (Estados Unidos, 1996).
The
DTPA soil test was developed to identify inadequate and excessive concentrations of plant-available micronutrients (Cu, Fe, Mn, Zn) in slightly acid and alkaline soils (Korcak and Fanning, 1978; Lindsay and Norvell, 1978; Norvell, 1984; O'Connor, 1988).
She also claimed that the defendants knowingly violated the
DTPA and that she was thus entitled to treble damages.
Slight decrease in
DTPA extractable Zn, Cu, Co, Cd and Pb content was observed compared to their initial values in recommended and site specifics use of chemical fertilizer i.e.
Concentration of available iron and zinc (FeoTPA, ZnoTPA) was extracted by 0.05 M
DTPA [8] and was measured by graphite furnace atomic absorption spectrometry.
Based on form factor, the agricultural micronutrients market is categorized into EDTA,
DTPA, EDDHA, HBED, and non-chelated.
