Investigations on Interception and Translocation of Airborne 85Sr, 131I, 137Cs in Beans, Spinach and Radish Plants
1998
Singhal, R. K. | Narayanan, U. | Bhat, I. S.
The work reported here deals with the study of interception/deposition and translocation of ⁸⁵Sr, ¹³¹I, and¹³⁷ Cs in three different types of vegetables i.e. beans (Phasoolus vulgaris), spinach (Spinicia olericia) and radish (Raphanous sative) following redionuclides release to the environment. Activity was injected in the experimental chamber in the form of aerosols having a size distribution of 0.3–1.0 µm (AMAD). Plant samples were collected soon after the injection for the evaluation of interception/deposition factors (IF/DF) for the different parts of the plants, as well as for the whole plant and the washable fraction of the deposited activity and its variation with time. The evaluated IF/DF shows a minimum value of 0.12 m³ kg⁻¹ for ⁸⁵Sr in case of spinach whole plant and maximum value of 1.93 m³ kg⁻¹ for ¹³¹I in case of beans whole plant. Translocation factors (TF) have also been evaluated for the activity that migrates from the above soil plant parts to the root and its variation with time. The evaluated TF shows a range of 7.27 × 10⁻³ to 136 × 10⁻³.

Papapetropoulou, Maria | Pagonopoulou, Olga
A study was carried out in order to estimate the presence of enteric and non-enteric indicators in the water distribution systems of Western Greece and to evaluate different methods for culture and isolation of coliforms in that region, under several incubation conditions and using different media. According to the different media and techniques used, the numbers of water samples found unsafe for consumption represented 21, 17 and 10% of the total, when mT7 agar, M-Endo agar LES (Membrane Filtration technique) and Most Probable Number (MPN) techniques were used, respectively. In one third of the samples oxidase positive microorganisms were present, which were almost eliminated by using anaerobic incubation of the media. Faecal streptococci were found only in 5% of the samples tested. The MPN technique proved to be significantly less efficient in recovering the coliform colonies than the Membrane Filtration (MF) technique (x² = 125.758 < 182.405). The use of m-Endo agar LES and mT7 agar showed no statistically significant difference in detecting total coliforms (x² = 162.55 > 162.422). However, a larger mean number of colonies per sample developed on mT7 agar, indicating that the latter medium should be used in our region for the detection of total coliforms.
