“…In case of complex matrices, e.g., soil in which many different chemical forms of the element may coexist, the modeling techniques such as PCA and target transformation are more convenient to use [23,24]. RPA is suitable for the X-ray absorption spectroscopic analysis of complex and dynamic systems such as metalloenzymes [11].…”

Determination of the chemical forms along with the relative quantity of the dierent species in a given sample, termed as speciation, can be done by analyzing X-ray absorption ne structure spectra. The dierent methods that can be used for speciation are: principal component analysis, target transformation, methods based on derivative spectra, method based on the relative position of the absorption edge, residual phase analysis, normalized dierence absorption edge spectra analysis and linear combination tting. An attempt has been made to make a comparative study of these dierent methods of speciation by recording the X-ray absorption ne structure at the copper K-edge in a mixture having cuprous oxide and cupric oxide in a specic ratio. The X-ray absorption ne structure spectra of the two oxides have also been recorded separately and the dierent characteristic X-ray absorption near edge structure features have been identied and their origins have been discussed. Speciation of the mixture has been done using these dierent methods and the results obtained have been compared and discussed.

“…It has been estimated that single application of the Bordeaux mixture introduced 3-5 kg Cu ha −1 in the region of Champagne (France) (Brun et al 1998). Similarly, Cu-rich pig and poultry slurries are sources of livestock grazing pasture contamination (Marschner 1995;Legros et al 2010). Other well-recognized anthropogenic sources of Cu include industrial and urban activities, wastewater and sewage sludge irrigation.…”

In recent years, copper (Cu) pollution in agricultural soils, due to arbitrary use of pesticides, fungicides, industrial effluent and wastewater irrigation, present a major concern for sustainable agrifood production especially in developing countries. The world's major food requirement is fulfilled through agricultural food crops. The Cu-induced losses in growth and yield of food crops probably exceeds from all other causes of food safety and security threats. Here, we review the adverse effects of Cu excess on growth and yield of essential food crops. Numerous studies reported the Cu-induced growth inhibition, oxidative damage and antioxidant response in agricultural food crops such as wheat, rice, maize, sunflower and cucumber. This article also describes the toxic levels of Cu in crops that decreased plant growth and yield due to alterations in mineral nutrition, photosynthesis, enzyme activities and decrease in chlorophyll biosynthesis. The response of various crops to elevated Cu concentrations varies depending upon nature of crop and cultivars used. This review could be helpful to understand the Cu toxicity and the mechanism of its tolerance in food crops. We recommend that Cu-tolerant crops should be grown on Cu-contaminated soils in order to ameliorate the toxic effects for sustainable farming systems and to meet the food demands of the intensively increasing population.

“…Various anthropogenic activities such application of pesticide, fungicide, Cu-rich pig and poultry slurries has elevated the Cu levels in agricultural soils (Legros et al, 2010;Nagajyoti et al, 2010), seriously impairing the plant growth. Elevated Cu concentration in the soils can alter the ionic form of the nutrients, making the unavailable for plant uptake or even toxic for plant growth (Adrees et al, 2015a(Adrees et al, , 2015bHabiba et al, 2015;Keller et al, 2015).…”
