“…This confirms previously reported results of increased accumulation of metals and nutrients (Vecchio et al 1984;Muchuweti et al 2006;Singh and Agrawal 2007;Pascual et al 2010) in soils and tissues of vegetable species grown on biosolid- Fig. 1 The shoot concentration factors (SCFs) of Cu (a), Zn (b), and Na (c) in pepper, tomato, collard, lettuce, and radish plants treated with biosolids at harvest.…”

“…Increased metal accumulation was reported in spinach and rice grown on sewage sludge-amended soils (Singh and Agrawal 2007;Singh and Agrawal 2011). The Zn and Cu concentrations in pepper fruits (Pascual et al 2010) and Cd in tomato fruits (Vecchio et al 1984) increased when plants were grown in sludge-applied soils. The detrimental impact of heavy metals on human and animal health will become apparent only after decades of exposure, so it is essential to monitor these metal constituents in plant tissues, and ultimately any excess builtup in the human food chain.…”

“…Pascual et al (Pascual et al 2010) reported that pepper fruits from plants grown in sludge-amended soils had lower concentrations of capsaicin and dihydrocapsaicin, resulting in lower pungency levels. Vecchio et al (Vecchio et al 1984) reported that tomatoes grown in sludge-amended soils had lower tissue firmness, titratable acidity, more tender skins, less sourness, and less intense characteristic tomato flavor, based on sensory evaluation.…”

The accumulation of metals and nutrients in biosolid-amended soils and the risk of their excess uptake by plants is a topic of great concern. This study examines the elemental uptake and accumulation in five vegetable plants grown on biosolid-applied soils and the use of spectral reflectance to monitor the resulting plant stress. Soil, shoot, root, and fruit samples were collected and analyzed for several elemental concentrations. The chemical concentrations in soils and all the plant parts increased with increase in applied biosolid concentrations. The Cu and Zn concentrations in the plant shoots increased in the order of collard

“…The redness-yellowness ratio (a=b) using the results from the Hunter colorimeter readings was reported to indicate the degree of redness of tomatoes and provides information regarding the changes in chroma or hue (Min and Zhang, 2003;Vecchio et al, 1984). The treatment of the tomatoes with ClO 2 did not significantly ( p < 0.05) affect the color of the tomatoes throughout the 28 days of storage as observed from the Hunter colorimeter readings (Table 4).…”

The main objective of this study was to determine survivability of a cocktail of three strains of Salmonella enterica (Montevideo, Javiana, and Baildon) and two strains of Listeria monocytogenes (LCDC 81-861 and F4244) on hydroponic tomatoes after treatment with chlorine dioxide (ClO(2)) gas. An initial concentration of 8-9 log cfu/mL of Salmonella and Listeria cocktails was inoculated individually, in separate experiments, on tomato skin to obtain a population of 7-8 log cfu/cm(2) after drying of the inoculums on the tomato skin. The aim was to achieve a 5 log reduction consistent with the recommendations of the National Advisory Committee on Microbiological Criteria for Foods. The tomato skins were treated with 0.1, 0.3, and 0.5 mg/L ClO(2) gas for 12 min at 22 degrees C and at the relative humidity of 90%. Untreated skin samples were processed under the same conditions. ClO(2)-gas-treated and untreated samples were recovered by an overlay method. The bottom layer contains tryptic soy agar, and the top layer consists of xylose-lysine-desoxycholate agar or modified Oxford antimicrobial supplement agar for Salmonella and Listeria, respectively. More than a 5 log reduction in Salmonella and Listeria was observed on the tomato skin surfaces after treatment with 0.5 mg/L ClO(2) gas for 12 min. Treatment with 0.5 mg/L ClO(2) gas for 12 min also delayed the growth of natural microflora on tomato surfaces and extended the shelf life of tomatoes by 7 days during storage at 22 degrees C, compared with the untreated control. These results revealed that ClO(2) gas is a promising antimicrobial technology for fresh tomato skin surfaces.

“…The field site is located in the old Cornell University orchard and in a neighbouring pasture, in Ithaca (New York). Soils in this orchard are moderately well-drained, were formed on a lacustrine deposit, and have been classified alternatively as a fine, illitic, mesic, Glossaquic Hapludalf (VECCHIO et al, 1984) or as a mixed, mesic Udic Hapludalf (MERWIN and STILES, 1994). The orchard was originally planted in 1927, but the trees were removed in 1977-78.…”

Preferential Flow: Water Movement and Chemical Transport in the Environment

View full text Add to dashboard Cite

Preferential flow has been increasingly recognized as a process of great practical significance for the transport of water and contamination in field soils. Recently, fractal has been applied to characterize the geometry of stain patterns of soil profiles. The field experiment involved loamy and sandy soils. The sequence of images of horizontal cross-sections of stain patterns in the two soils suggest that fingering occurred in the loamy soil, not in the sandy soil. Yet, the surface fractal dimensions of the stain patterns are very similar in both cases. This similarity suggests that these dimensions provide information not so much on the geometry of the stain patterns but more directly on the fractal properties of the pore network in the soil. This viewpoint is confirmed partially by the evidence of a good correlation between the surface fractal dimension and the exponent of a Van Genuchten expression applied to the particle size distribution of the soil.
