“…The greater amount of lead (2130%), as compared with cadmium (911%) bound to F4 results from a strong affinity of lead to organic matter, which is expressed by the formation of complex connections between this metal and organic compounds in the soil. This is confirmed by numerous results of Pb speciation in soils and sediments (Domañska 2008;Lucho-Constantino et al 2005;Tarchouna Gharbi et al 2010;Wysokiñski and Kalembasa 2012).…”

“…According to Karczewska (1995), in contaminated soils, which are subject to periodic inflow processes, partial release of metals such as Cu, Pb, and Zn can occur, and neutral soil pH probably does not protect against such mobilization. In contrast, Lucho-Constantino et al (2005) demonstrated a significant correlation between the time of hydration, lead content (total, exchangeable fraction, and fraction bound to organic matter and sulfides), as well as organic carbon.…”

“…Such an amount of fraction easily available for plants can pose a risk of an excessive uptake of the metal by plants. This value is above allowable limit for the mobile fraction, which is set in Sweden for 1.0 mg Pb×kg 1 (Lucho-Constantino et al 2005). The high abundance of the test soil in organic matter contributed to the accumulation of metals in the organic fraction (F4).…”

Abstract:The studies were carried out on the basis of field experiment. The purpose of this study was to determine the effect of purified municipal sewage, applied in single (optimal for plant growth) and double doses, on the content of Cd and Pb, and its chemical speciation in organic neutral soil. The sequential extraction procedure was used to separate Cd and Pb from soil into 5 operationally defined fractions: exchangeable F1, carbonate bound specifically bound F2, bound to Fe-Mn oxides F3, bound to organic matter F4, and residual F5. The total content of Pb in reference soil and in soils treated with sewage was lower than permissible values accepted in Poland for natural soils, while the content of Cd exceeded the highest acceptable level for natural organic soils. The Cd association with different geochemical fractions, both in soil fertilized with sewage, and unfertilized (control) soils, followed the order [%]: F3>F2>F4>F1³F5. Cadmium was associated mainly with F3 (5160%) and F2 (2326%) fractions, while 68% was stated in exchangeable form (F1). Speciation distribution of Pb was lined up in the order [%]: F3>F4>F2>F5>F1. Lead was retained mainly in F3 (4656%), F4 (2130%) and F2 (1013%) fractions. In soils treated with sewage there were stated the higher amounts of metals bound to organic fraction compared to reference soil.

“…The normal distribution of the data was verified by the Kolmogorov-Smirnov and Shapiro-Wilk tests. Pearson correlations were also calculated (0.01 ≤ p ≤ 0.05) to identify the minimal significance of the senescence stage, but only the 0.05 significance level was further used to assess the loadings to be considered in FA [22]. Finally, FA with Varimax rotation was conducted either with the original data set or with standardised data, according to the method of Lucho-Constantino et al [22].…”

Abstract:Species of the genus Opuntia may be a well-suited feedstock for biorefineries located in drylands, where biomass is scarcer than in humid or temperate regions. This plant has numerous uses in Mexico and Central America, and its mucilage is a specialty material with many promising applications. We extracted the mucilage from a forage species, O. heliabravoana Scheinvar, and mixed it with a thermoplastic starch to produce an edible coating. The coating was applied to blackberries, which were then evaluated in terms of several physicochemical and microbiological variables. During a 10-day evaluation period, the physicochemical variables measured in the coated fruits were not significantly different from those of the control group. However, the microbiological load of the coated fruits was significantly lower than that of the uncoated fruits, which was attributed to a decreased water activity under the edible coating. Multivariate analysis of the physicochemical and microbial variables indicated that the storage time negatively affected the weight and size of the coated and uncoated blackberries. Although some sensory attributes have yet to be optimised, our results support the use of the mucilage of forage Opuntia for the formation of edible coatings, as well as their valorisation through a biorefinery approach.

Today, due to the constraint in availability of the freshwater for irrigation, wastewater is being used for irrigation of agriculture fields. Wastewater contain plant nutrients that favour crop growth but leave a burden of heavy metals which can enter the food chain and is a cause of great concern. This research work aimed at evaluating the potential utilization of wastewater as an alternative source of water and nitrogen (N) for fenugreek. For this purpose, a pot experiment was conducted with wastewater and four doses of nitrogen (0, 20, 40 and 60 kg.ha -1 ) to observe a comparative effect on growth and biochemical characteristics using fenugreek as the test crop.Wastewater and soil used in the experiment were analyzed for their physicochemical properties. Results indicate that wastewater was richer in essential plant nutrients but contained some heavy metals in amounts well below the permissible limits for its use as irrigation water. Use of wastewater with 20 kg.N.ha -1 improved growth, proline and antioxidant enzymes of the plant as compared to application of groundwater with no fertilizer. Lipid peroxidation increased with wastewater but decreased with the increasing nitrogen doses, so the best combination (WW×N 20 ) has negative impact on this parameter. These results concluded that wastewater can efficiently substitute groundwater and also works as a nutrient source whereas application of nitrogen could provide protection against the oxidative stress by increasing the antioxidant protective system.
