“…The experiment at Torviscosa, NE Italy (45˚49′N, 13˚16′ E, 14 m above sea level, mean annual temperature 13.5˚C, average annual rainfall 1200 mm) was organized in a randomized block design with two factors, species and treatment, and three replications [9]. The substrate of the experimental site is polluted by several heavy metals and As; currently, this site and the surroundings are included in the national priority list of polluted sites.…”

“…The amounts of elements removed from the soil were calculated by multiplying the average concentrations of elements in the shoots, reported in Marchiol et al [9], and the biomass yield ( Table 3). Being derived from the plant biomass, this parameter mainly reflects the effects of the different fertilizations observed for the biomass yield.…”

“…Regarding Italy, the field experiment of Torviscosa is cited and-so far-it is the only phytoremediation experiment performed at field scale within an industrial site [9]. As this trial was managed by our group, the present study reports a study that shows 1) How the principles of plant growth analysis [10] can be used in the field of phytoremediation, and 2) Reports the uptake and removal of elements recorded growing Sorghum bicolor in a multi-metal contaminated soil.…”

“…Sunflower (Helianthus annuus L.) is an increasingly important source of vegetable oil and biomass, usefully employed for food, chemical, energy, and industrial purposes (Riva and Calzoni, 2004). It is believed that the plant had the capacity to absorb heavy metals (Madejon et al, 2003;Vamerial et al, 2012), but these components probably accumulated in the roots rather than shoot and plant seeds (Madejon et al, 2003;Marchiol et al, 2007;Adesodum et al, 2010). The objectives of this study were to evaluate the effects of treated municipal wastewater on the yield and heavy metals content of the sunflower seed.…”

Treated wastewater could be considered as a new water resource in agriculture especially in arid and semi-arid regions of the world such as Iran. Two one-year field experiments were carried out to determine the effects of municipal treated wastewater on yield and seed heavy metals content of sunflower cultivars, in Research Farm of Yazd Municipal Wastewater Purification Station during 2015 and 2016. The climate of the region was hot and dry according to Koppen climate classification system. Experiment was arranged as split plot based on randomized complete block design with three replicates. Treatments were three irrigation water types as main plot consisted ("WW": irrigation with treated municipal wastewater thoroughly, "WW/FW": irrigation with treated wastewater/fresh water alternatively and "FW": irrigation with fresh water thoroughly) and three sunflower cultivars (Azargol, Record, and Farrokh) as subplots. The following parameters were assessed: plant height (cm), head diameter (cm), seed numbers per head, unfilled seeds per head, seed and biological yield (kg/ha) and seed heavy metals content. Results showed that the highest plant height (194 cm) obtained in Record and the highest head diameter (21.5 cm) obtained in Farrokh cultivars, which were irrigated by WW. Treated municipal wastewater also increased seed yield by 10.7% compared to FW treatment. The highest (5029 Kg/ha) and lowest (3734 Kg/ha) seed yield were obtained in Azargol and Farrokh that irrigated with WW and WW/FW treatment, respectively. However, application of treated municipal wastewater lead to accumulation of trace elements (Fe, Mn, Zn, Cu, Cd, Pb, and As) in seeds; but, the values of all the elements were below the permissible limits recommended by World Health Organization. It is concluded that WW could be used for irrigating sunflower crop without worrying about the accumulation of toxic substances.

The food security in today's world is endangered by several threats, including accelerated increases in the world's population, depletion of the Earth's resources, exaggerated environmental pollution, and foreseen climatic changes. As a strategy to diminish these threats, the wise disposal of the huge amounts of sewage sludge (SS) to agricultural soils as a bio-fertilizer represents a worthy practice for recirculating valuable nutrients to food chains via crop plants. The current study was designed to scientifically test the feasibility of SS application to agricultural soils without causing environmental or health threats. Different SS amendment doses of 0, 10, 20, 30, 40, and 50 g/kg were supplied for soil-grown barley (Hordeum vulgare L.) plants.Our results show that all of the SS amendment doses improved the postharvest soil properties and enhanced barley growth, with the best results obtained at the 40 g/kg dose. At this amendment dose, the organic matter (OM) content increased to 6.7% compared with 1.4% in control soil. Analysis of the postharvest soils showed that the concentrations of the investigated heavy metals (HMs) (Co, Cu, Mo, Ni, Zn, Cd, Cr, and Pb) were within the allowable limits for agricultural soils at all of the SS amendment doses, except for Co. All of the SS amendment rates enhanced barley growth and yield parameters, including shoot and root lengths and dry weights, spike weight and number of spikes per plant. Up to the 40 g/kg amendment dose, the concentrations of the investigated HMs in the harvested plant tissues were within safe limits, with most of the absorbed HMs persisting in roots. Taking these results together, the current study suggests that controlled application of SS to agricultural soils represents an eco-friendly SS disposal procedure, which can recycle macro-and micronutrients to food chains and hence provide a promising approach for sustainable food security.
