“…This may be because of the presence of car repair shops which release large amounts of these heavy metals. Cd concentration in the onion plants of this study was higher than the results of Fahim et al, [11], and less than the results obtained by ElNaim et al, [10]. Concentration of Cd in the radish in The differences were insignificant among other locations, though the highest concentration was found in the Shele location.…”

This research is conducted to evaluate the levels of some heavy metals (such as lead, cadmium, nickel, and copper) and their concentrations in water and in the most common vegetables (chard, celery, leek, onion and radish) which are cultivated in five common locations in Dohuk city farms, and irrigated with wastewater. The study in the concentration of heavy metals found in water used for vegetable irrigation indicates that the water of the College of Agriculture is not contaminated; while the water from all the other locations was highly contaminated. The results from the vegetable content analysis of heavy metals indicate that chard plants accumulate more lead and cadmium, while radish plants accumulate less. Concentrations of lead (Pb) and cadmium (Cd) obtained from vegetables grown in all the studied locations exceeds significantly in concentrations when obtained from the College of Agriculture location. Their relatively high concentration exceeds maximum permissible levels (MPL) in vegetables (WHO). The mean (Pb) concentrations of chard, celery, leek, onion, and radish plants were 4.188; 4.0; 3.719; 3.663; and 2.66 mg. kg -1 d. wt respectively, while the mean Cd concentration in chard, celery, leek, onion, and radish plants were 0.422, 0.37, 0.355, 0.346, and 0.228 mg. kg -1 d. wt respectively. Among locations, the Dilan Hall appeared to be more contaminated, whereas the College of Agriculture location is less contaminated. The concentration of both nickel (Ni) and copper (Cu) in all studied vegetables and in all locations didn't exceed (MPL) in vegetables. Mean Ni concentrations in chard, celery, leek, onion, and radish plants were 3.73; 4.07; 3.45; 3.66; and 3.25

“…When biosolids are stabilized by high lime treatment, they can also have some value as a liming material for acidic soils and can substitute for agricultural lime (Jacobs and McCreary, 2001;El-Naim et al, 2004). One study, which encouraged lime treatment, was reported by ElNaim et al (2004).…”

ABSTRACT:Reuse of domestic wastewater that does not contain heavy metals or pathogenic microorganisms, as irrigation water is a significant method in terms of water conservation all around the world. In this field trial which was conducted over two years, the domestic wastewater (DW) of Muğla City after being alkaline stabilized was used to irrigate maize plant for silage and the interaction of soil and water was also controlled during the trial. Alkaline stabilized domestic wastewater (ASDW) was applied in four different doses as 150 ton ha -1 , 300 ton ha -1, 450 ton ha -1 and 600 ton ha -1 . During the vegetation stage, periodic physical observations were done and soil and plant samples were collected in order to evaluate the state of nutrition and effects of alkaline stabilized domestic wastewater. In the analysis, it was determined that pH and salt content of the soil didn't change and the contents of Ca and Mg elements increased. Chemical composition, in vitro metabolic energy values and pH of silage feedstuffs samples were investigated. In comparison with control, alkaline stabilized domestic wastewater treatment increased dry matter, crude protein, crude fat (as ether extract) and thus the metabolic energy (ME) content of feedstuffs. For silage yield, crude protein and metabolic energy, the best results were obtained with 600 ton ha -1 application. According to the results, after alkaline stabilized domestic wastewater application to soil, which is a finite natural resource, soil was not negatively affected, and the quality and physiological features of maize for silage were affected affirmatively. In conclusion, alkaline stabilized domestic wastewater can be reused as a source of irrigation water and fertilizer for agricultural purposes.

Muğla İlinde iki yıllık tarla denemesiyle kireçle stabilize edilmiş kentsel atık sular silajlık mısır bitkisinin sulanmasında kullanılmış ve deneme süresince toprak ve su etkileşimleri kontrol altında tutulmuştur. Atık su; 150 ton ha -1 , 300 ton ha -1, 450 ton ha -1 ve 600 ton ha -1 olmak üzere 4 farklı dozda uygulanmıştır. Vejetasyon süresince uygulanan atık suların toprağa ve bitkiye olan etkisini değerlendirmek amacıyla periyodik olarak toprak ve bitki örnekleri toplanmış ve fiziksel gözlemler yapılmıştır. Analizler sonucunda toprağın pH ve EC değerlerinin değişmediği ancak Ca ve Mg kapsamlarının arttığı tespit edilmiştir. Silaj örneklerinin kimyasal kompozisyonu, in vitro metabolik enerji ve pH değerleri silaj öncesi ve sonrası ayrı ayrı olmak üzere değerlendirilmiş ve kontrol uygulamaları ile atık su uygulama grupları karşılaştırıldığında; kuru madde, ham protein, ham yağ ve metabolik ener...

“…It results from the fact that it is characterised by a rich variety of nutrients, a considerable amount of organic matter and physical properties that improve soil structure (El-Naim et al, 2004;García-Gil et al, 2004). However, numerous studies have shown that sewage sludge can contain mutagenic and carcinogenic pollutants such as polycyclic aromatic hydrocarbons (Bodzek et al, 1997;Stevens et al, 2003;Baran and Oleszczuk, 2003a).…”

In order to improve properties of compost produced from sewage sludge, a wide range of additives is used. The aim of the present study has been to determine the influence of fly ash and sawdust on the range of losses of 16 PAHs (US EPA). Composting was carried out in containers in which there was sewage sludge (100%), sewage sludge with fly ash added (20 or 30% w/w) and sewage sludge with sawdust added (30% w/w). Composting was carried out for 353 days. Then the compost obtained was stored for another 300 days. The content of 16 PAHs was determined using the HPLC-UV method.After composting, in all the experimental treatments, ie, with sludge alone, and with the additions of 20% and 30% fly ash, and sawdust, decreases in the total PAH load of 87.5, 83.4, 82.9 and 88.1% respectively, were found. The content of the total PAH load was mainly determined by 3-ring compounds. In the case of these last PAHs the highest level of their disappearance (>90%) was noted after composting. In all composts obtained, the content of PAHs was within allowable limits for biosolids that can be used for agricultural purposes.A significant lowering of total concentration of the 16 PAHs after storage period was noted only in the experimental variant with 20% of fly ash. However, the process of composts storage influenced individual PAHs.
