“…Only Ca (C2 and C3) varied in the seeds. As in other wastewater studies (PEREIRA et al, 2011;RODDA et al, 2011;SHAHBAZ et al, 2011;KHAJANCHI-LAL;MINHAS;YADAV, 2015), the produced water significantly altered the chemical composition of the sunflower roots, shoots, and seeds. However, nutrient content variation in the plant tissues reflected the water treatment, which is in agreement with the observations of Kiziloglu et al (2008).…”

“…This effect has also been observed with other types of wastewater (HEIDARPOUR et al, 2007;MORUGÁN-CORONADO et al, 2011;SHAHBAZ et al, 2011;SOU/DAKOURÉ et al, 2013). Salt stress negatively influences the development of the plant because high levels of Na has a phytotoxic effect on the plant (SHAHEEN et al, 2013) and decreases the accumulation of essential nutrients in the plants' tissues (PEREIRA et al, 2011;SHAHBAZ et al, 2011). However, the negative effect depends upon the ability of the species to tolerate a high Na content in their tissues, or even due to the presence of ions that can buffer the phytotoxic effect of Na (KAMALULDEEN et al, 2014).…”

“…In this study, plants irrigated with OPW showed the greatest accumulation of nutrients in plant tissues after three consecutive crop cycles, with Ca, Na, N, P, and Mg levels increasing in the roots. In contrast, FPW adversely affected the plants, as Na tends to accumulate over time, a situation that can induce nutritional imbalances and damage plant growth (MORUGÁN-CORONADO et al, 2011;PEREIRA et al, 2011;SOU/DAKOURÉ et al, 2013). Additionally, N and P levels in the shoots and Ca, Mg, K, Na, and P levels in the seeds of plants irrigated with FPW decreased with subsequent cultivations.…”

“…Wastewater irrigation can raise the levels of nutrients and organic matter in the soil (XU et al, 2010;SINGH et al, 2012;BEDBABIS et al 2014;KHAJANCHI-LAL;MINHAS;YADAV, 2015) and the macronutrients in plant tissues (KIZILOGLU et al, 2008;PEREIRA et al, 2011;RODDA et al, 2011). Both of these may have a positive effect on agricultural production.…”

“…Both of these may have a positive effect on agricultural production. However, heavy metals and salts may also accumulate in soils and plant tissues and reach toxic levels (MORUGÁN-CORONADO et al, 2011;PEREIRA et al, 2011;RODDA et al, 2011;SOU/DAKOURÉ et al, 2013;BEDBABIS et al 2014). The high uptake of salt by plants is the main issue with the use of wastewater irrigation (PEREIRA et al, 2011;MORUGÁN-CORONADO et al, 2011), as high levels of Na decrease the accumulation of nutrients in plants (PEREIRA et al, 2011;SHAHBAZ et al, 2011).…”

-Irrigation using produced water, which is generated during crude oil and gas recovery and treated by the exploration industry, could be an option for irrigated agriculture in semiarid regions. To determine the viability of this option, the effects of this treated water on the nutritional status of plants should be assessed. For this purpose, we examined the nutritional changes in sunflowers after they were irrigated with oil-produced water and the effects of this water on plant biomass and seed production. The sunflower cultivar BRS 321 was grown for three crop cycles in areas irrigated with filtered produced water (FPW), reverse osmosis-treated produced water (OPW), or ground water (GW). At the end of each cycle, roots, shoots, and seeds were collected to examine their nutrient concentrations. Produced water irrigation affected nutrient accumulation in the sunflower plants. OPW irrigation promoted the accumulation of Ca, Na, N, P, and Mg. FPW irrigation favored the accumulation of Na in both roots and shoots, and biomass and seed production were negatively affected. The Na in the shoots of plants irrigated with FPW increased throughout the three crop cycles. Under controlled conditions, it is possible to reuse reverse osmosis-treated produced water in agriculture. However, more long-term research is needed to understand its cumulative effects on the chemical and biological properties of the soil and crop production.Keywords: Residual water. Salinity.

TEORES DE NUTRIENTES EM GIRASSOL IRRIGADO COM ÁGUA DA INDÚSTRIA DE PETRÓLEORESUMO -Irrigação com água produzida, que é gerada durante a extração de petróleo bruto e gás pode ser uma opção para agricultura irrigada em regiões semi-áridas mas o efeito desta água tratada no estado nutricional das plantas e no crescimento e desenvolvimento das culturas deve ser avaliado. Com esse propósito, determinamos alterações nos aspectos nutricionais da cultura de girassol irrigado com água produzida e os efeitos na produção de biomassa e de grãos de girassol. O girassol cv. BRS 321 foi cultivado durante três ciclos em áreas irrigadas com água produzida filtrada (FPW) e tratada por osmose (OPW) e água subterrânea (GW). Ao final de cada ciclo, raízes, parte aérea e grãos foram coletados para determinar as concentrações de nutrientes. Irrigação com água produzida afetou o acúmulo de nutrientes em plantas de girassol. Irrigação com OPW promoveu acúmulo de Ca, Na, N, P e Mg. Plantas irrigadas com FPW acumularam maiores teores de Na em raízes e parte aérea, e afetou negativamente a produção de biomassa e de grãos de girassol. Os níveis de Na na parte aérea de plantas irrigadas com FPW aumentaram ao longo dos três ciclos de cultivo. Sob condições controladas, é possível reutilizar a água produzida tratada por osmose inversa na agricultura, mas necessita de mais estudos a longo prazo para compreender o efeito cumulativo, nas propriedades químicas e biológicas do solo e na produção das culturas. Estes resultados sugerem que a irrigação com...

Treated industrial effluents have high levels of nutrients and dissolved organic matter. The irrigation of rice by flooding can increase nutrient uptake and grain yield. Therefore, this study evaluated the nutrient contents in the shoots and grain of the rice crop and also the chemical of the soil after irrigation of the crop with leachate of the treated industrial effluent. A greenhouse experiment was conducted using pots filled with 20 kg of soil in a randomized block design with three replications. The treatments consisted of control (irrigation with distilled water) and four concentrations of the leachate (25, 50, 75, and 100 %) for irrigation. At the end of the experiment, the nutrient contents in tissues of rice plants, sterility of spikelets, and grain mass were evaluated. Results showed that irrigation with the leachate at 25 % content increased the macro-and micronutrients' concentrations in the shoot biomass and grain, except for potassium and iron. Irrigation with the industrial leachate decreased tillering and grain yield; however, it increased chlorophyll content, sterility of spikelets, and sodium intake at this leachate concentration. The potassium and sodium levels and the electrical conductivity values of soils irrigated with treated industrial leachate were increased. The use of the treated leachate from industrial effluents is an alternative that reuses the nutritional load, but the volume of leachate should be limited and monitored to prevent the sodicity in the soil and problemsdue to eutrophication.

Cadmium (Cd) concentration in arable soil has drawn broad public attention due to its direct effect on Cd concentration in food. However, there have been few studies of surveying Cd accumulation on the national scale in China. This paper collected 486 studies of Cd concentrations in Chinese arable soil. The results showed that the average Cd concentration was 0.27 mg/kg, higher than its background value, indicating that Cd had been introduced into arable soil by human activity. The Cd concentrations in areas of mining and smelting, urban areas, and areas irrigated by wastewater were obviously higher than that in remote areas. Spatially, Cd concentrations were lower in the north than those in the south, and many hotspots existed throughout China due to mining and smelting activities. Most Cd in the arable soil were accumulated from external sources in all investigated provinces except Ningxia Hui Autonomous Region.
