“…In fact, high soil pH, clay and organic matter content are not supporting Pb uptake via roots. On the other hand, Kylander et al (2003) analyzed in Accra a Pb distribution following traffic density as also shown in other studies (Baye and Hymete 2010;Osma et al 2013;Teju et al 2012). Since lead is not biodegradable, and highly immobile, once soil has become contaminated, it remains a long-term source of dust exposure, although lead-free gasoline dominates today's market.…”

Heavy metal accumulation and health risk assessment in wastewater-irrigated urban vegetable farming sites of Addis Ababa, Ethiopia

Background: Wastewater irrigation for vegetable production is a highly prevalent practice in Addis Ababa and a number of articles have been published on wastewater-irrigated soils and vegetables contaminated with heavy metals. However, to the best of our knowledge, an insight into assessment of human health risks associated with the consumption of vegetable crops grown on wastewater-irrigated soils is non-existent in the city. Long-term effect of wastewater irrigation on the build-up of heavy metals in soils and selected vegetable crops in Addis Ababa urban vegetable farming sites (10) was evaluated. By calculating estimated daily intakes (EDIs) and target hazard quotients (THQs) of metals, health risk associated with the consumption of the analyzed vegetables was also evaluated. Results: The heavy metal concentrations in irrigation water and soils did not exceed the recommended maximum limits (RMLs). Moreover, Cd, Co, Cr, Cu, Ni and Zn concentrations in all analyzed vegetables were lower than the RML standards. In contrast, Pb concentrations were 1.4-3.9 times higher. Results of two way ANOVA test showed that variation in metals concentrations were significant (p < 0.001) across farming site, vegetable type and site x vegetable interaction. The EDI and THQ values showed that there would be no potential health risk to local inhabitants due to intake of individual metal if one or more of the analyzed vegetables are consumed. Furthermore, total target hazard quotients (TTHQs) for the combined metals due to all analyzed vegetables were lower than 1, suggesting no potential health risk even to highly exposed local inhabitants. Conclusions: There is a great respite that toxic metals like Pb and Cd have not posed potential health risk even after long term (more than 50 years) use of this water for irrigation. However, intermittent monitoring of the metals from irrigation water, in soil and crops may be required to follow/prevent their build-up in the food chain.

“…The samples were divided into two sub-samples; the samples in the first sub-group were thoroughly washed several times with tap water, and subsequently by distilled water in order to to remove dust particles in a standardized procedure; the rest of the vegetables were untreated, and then oven dried at 80 o C for 24 h. At each site, the soils were sampled from the top 10 cm by means of a stainless steel trowel to avoid contamination. To ensure consistent distribution of metals in the soil samples, all materials were grounded in a microhammer cutter, and filtered via a 1.5-mm sieve (Demirezen and Aksoy, 2006;Osma et al, 2013).…”

ABSTRACT:In this study, the effects of irrigation water on vegetables were analysed. Samples that we analysed were pepper (Capsicum annuum L.), tomatoes (Solanum lycopersicum L.), and eggplant (Solanum melongena L.) were raised using running water and river water and collected from both normal land and riverside soils. After pretreating the collected samples in the laboratory, ICP-MS elemental analysis was conducted. Results are evaluated using SPSS 19 Statistical Package Software and expressed as mean we found that there is significant differences in the content metals of the samples (soil, roots and fruits) collected from three different area. We also evaluated the correlation between the soils and the roots vegetable in terms of heavy metals (or mineral). It was clear that there is a significant effect of irrigation water on the vegetables. Key words: Heavy metals, ICP-MS, irrigation, mineral elements, vegetablesÖZET: Bu çalışma ile sulama suyunun sebzeler üzerinde ki etkileri araştırılmaya çalışılmıştır. Normal arazi ve nehir kenar topraklarından olmak üzere üç farklı örnek alan hazırlanmıştır. Bu alanlarda normal şebeke suyu ile nehir suyu kullanılarak, biber (Capsicum annuum L.), domates (Solanum lycopersicum L.) ve patlıcan (Solanum melongena L.) yetiştirilmiştir. Toplanan örnekler, laboratuvarda ön işlemden geçirildikten sonra ICP-MS te element analizi yapılmıştır. Elde edilen sonuçlar doğrultusunda SPSS 19 İstatistik Paket Programı ile istatistiksel değerlendirmeler yapılarak, üç farklı alandan toplanan örneklerin metal içeriği bakımından toprak, kök ve meyveler arasında farklılıklar tespit edilmiştir. Ayrıca metal açısından toprak ile sebzelerin kökleri arasındaki korelasyon ile toprak-kök arasındaki ilişki de belirlenmiştir. Sulama suyunun, sebzelerde önemli etkisinin olduğu açıktır.Anahtar Kelimeler: Ağır metaller, ICP-MS, mineral element, sebze, sulama

“…After each milling, to protect plant sample from microbial decomposition, mortar was cleaned with ethyl alcohol and distilled water. To ensure the uniform distribution of metals in sample, materials were milled in a micro-hammer cutter, sieved through a 1.5-mm sieve and kept in clean polyethylene bags (Markert, 1993;Osma et al, 2012). Lipid peroxidation level was measured using Heath and Packer method (1968) with slight modifications (Ananieva et al, 2002).…”

Water contamination by heavy metals is a serious global problem due to increased environmental and health-related issues. In this study, we have comparatively investigated the heavy metal concentrations and mineral nutrient levels in Karasu river sediments and in plants samples of Phragmites australis (Cav.) in order to assess the biomonitoring capacity. Plant and sediment samples were collected from four different localities along Karasu River, and those samples were analyzed in terms of heavy metals such as Fe, Zn, Mn, Ni, Cr, Cu, Pb, Co and Cd, and in terms of mineral elements such as K, Ca, Mg, Na, Al, and B using ICP-OES. In addition, lipid peroxidation, chlorophyll and carotenoid levels in plant samples were also checked. Sediments in Karasu River contained high concentrations of Ni and Cr metals. Moreover, P. australis showed hyper-accumulation for Cd and Zn in root and leaf samples, respectively. Although there was no significant difference in chlorophyll amounts among locations, lipid peroxidation was found to be high in samples taken from İliç.
