“…The link between wastewater irrigation and elevated levels of soil Cd, Pb and Zn is well documented (Shariatpanahi and Anderson 1985;Yadav et al 2002;Sharma et al 2007;Fig. 2 Differences in wheat straw biomass (DW) under CW and WW irrigation following (a) Factorial ANOVA and b) following Factorial ANOVA with the inclusion of ECe as a covariate Janali et al 2007;Gupta et al 2008;Bahmanyar 2008;Qishlaqi et al 2008).…”

“…However, the direct and indirect use of untreated wastewater in irrigated agriculture is increasing as a result of increasing global water scarcity, inadequate and inappropriate wastewater treatment and disposal, increased food insecurity and escalating fertilizer costs (Scott et al 2004;Qadir et al 2007;Jimenez and Asano 2008). Agronomic studies investigating untreated wastewater re-use have focused primarily on vegetable production systems and both heavy metal and microbiological food chain contamination (Shariatpanahi and Anderson 1985;Yadav et al 2002;WHO 2006Sharma et al 2007Janali et al 2007;Gupta et al 2008;Bahmanyar 2008;Qishlaqi et al 2008). The impacts of wastewater re-use on the performance of staple crops such as wheat have been largely neglected (Yadav et al 2006).…”

In 2006 a comprehensive sampling program was undertaken in two pre-selected peri-urban villages in Faisalabad, Pakistan to evaluate the soil and agronomic impacts of long-term (25-30 years) untreated wastewater re-use on wheat grain and straw yields and attributes of wheat straw fodder quality. Soil SAR, ESP, RSC and ECe were 63%, 37%, 31%, and 50% higher under wastewater (WW) as compared with canal water (CW) irrigated plots. Further, 2.7 and 6.65 fold increases in soil NO 3 − + NO 2 − -N and Olsen-P were observed in WW as compared with CW irrigated plots. However, no significant differences in grain yield, wheat straw biomass, or fodder quality attributes were observed between WW and CW irrigated plots. In addition, for both CW and WW irrigated plots wheat straw, Cd and Pb concentrations were orders of magnitude below the EC Maximum permissible levels for Pb and Cd in feed materials and thus pose no threat to the fodderlivestock food chain. Further, elevated soil N associated with WW irrigated plots has a significant (p<0.01) positive influence on fodder quality by increasing the N content. Irrig Drainage Syst (2010) 24:95-112

Heavy metal pollution of agricultural soils and air is one of the most severe ecological problems on a world scale and in Bulgaria in particular. The biggest sources of pollution in Bulgaria are some non-ferrous metals smelters, such as the Non -Ferrous Metals Combine (NFMC) near Plovdiv, situated on very fertile soils. Vegetable, arable and animal production in this area results in contaminated produce with excessive amounts of Cd, Pb, Cu, Mn and Zn.In order to discover some crops which could be grown on these areas without contamination of the end product, we conducted (in 1991-1993) field experiments in the vicinities of NFMC near Plovdiv. As experimental material we used Mentha piperita L. (cv Tundza and Clone No 1) and Mentha arvensis var piperascens Malinv. (cv . Plants have been grown on three Plots: Plot No 1 -at a distance of 400 m from the source of pollution; Plot No 2 -at 3 km from the source of pollution and on a control Plot -in the experimental gardens of University of Agriculture in Plovdiv, at 10 km from the source of pollution. It was established that heavy metal pollution of soil and air at a distance of 400 m from the source of pollution decreased the yields of fresh herbage by 9-16% and the yield of essential:oil by up to 14% compared to the control, but did not negatively affect the essential oil content and its quality.Oils obtained from Plot 1 at a distance of 400 m from the source of pollution have not been contaminated with heavy metals.Cultivar response to heavy metal pollution was established. A positive correlation between Pb concentration in leaves and in essential oil was found.Heavy metal concentration in the plant parts was found to be in order: for Cd roots > leaves > rhizomes > stems; Pb roots = leaves > rhizomes = stems; Cu roots > rhizomes = stems = leaves; Mn roots > leaves > stems = rhizomes; Zn leaves > roots > stems = rhizomes.The tested cultivars of peppermint and cornmint could be successfully grown in highly heavy metal polluted areas, as in the area around NFMC near Plovdiv, without contamination of the end product -the essential oils.Despite of the yield reduction (up to 14%), due to heavy metal contamination, mint still remained a very profitable crop and it could be used as substitute for the other highly contaminated crops.

“…The toxic effects of Hg on seed germination, growth and yield have been studied in different plant species (Mukherjee and De 1996;Varshney 1991;Vizarova et al 1985). Long term exposure of Hg into the agricultural field results into the accumulation of toxic level of the element in the vegetables (Shriapanahi and Anderson 1986). The interaction between Hg and plant systems is very important because Hg has largely been employed in seed disinfectants, in fertilizers and in herbicides (McLaughlin et al 1996).…”

The phytotoxicity and oxidative damage in response to different concentrations of Hg (0.0, 2.5, 5.0, 10 and 25 μM) were evaluated in wheat plants. The root and shoot growth, content of chlorophyll and total soluble protein declined at 10 and 25 μM Hg. Roots of the plant were more affected as compared to the shoot. The malondialdehyde (MDA) quantity enhanced in the roots of wheat plants treated with 10 and 25 μM Hg and in the leaves of plants treated with 25 μM Hg. The concentration of H 2 O 2 decreased at low concentration and increased at high concentration of Hg. The induction of enzymatic antioxidants (catalase, CAT; ascorbate peroxidase, APX; peroxidase, POX and superoxide dismutase, SOD) was found in the roots and leaves of plants with increased concentration of Hg up to 10 μM and low activities of these enzymes were observed at 25 μM Hg. Also, the level of K, Ca and Mg declined in leaf tissues of Hg treated plants. Thus wheat plants exposed to lower concentrations of Hg did not experience any oxidative stress. However, on treatment with 10 μM Hg, the roots and leaves responded differently. Both the leaves and roots of plants treated with higher concentration of Hg were subjected to comparatively greater oxidative damage and demonstrated that the antioxidative components were not able to remove the stress due to higher concentration of Hg and thus might affect the productivity in wheat plants.
