“…This finding agrees with the findings of previous studies with regard to heavy metal contamination in the edible parts of vegetables produced in waste water irrigated sites. Studies conducted by Muchuweti et al (2015), Sharma et al, (2015) and Liu et al (2005) also demonstrated that plants grown on wastewater-irrigated soils are generally contaminated with heavy metals, which pose a major health concern (Muchuweti et al, 2015;Sharma et al, 2015;Liu et al, 2015;Hossain et al, 2015). Rana et al, (2014) during a study on the determination of heavy metals content in vegetables irrigated by Hudiara drain water shows that vegetable samples contain some amount of heavy metals.…”

The study is aimed at assessing monthly heavy metals variation in some selected vegetables sampled from Kasuwan Mata, Igabi Local Government Kaduna. Vegetables samples were collected and analysed for Pb, Cu, Zn, Ni, Mn Cr and Cd using Atomic Absorption Spectrophotometric techniques for the period of 4 month. Results show high heavy metal concentration in the month of november when compared to the month of august, September and October, all the heavy metal concentration in the vegetables were within WHO/FAO permissible limits but these can cause hazardous health effects in people, who are ingesting these vegetables for long period of time due to magnification of these heavy metals in their body. It is thereby recommended that KEPA should serve as references laboratory for the approval of farmers that intend to undertake dry farming.

“…Demirezen and Ahmet (2006) reported that, Cu concentration (22.19-76.50 mg/ kg) was found higher in leafy vegetables as compared to non-leafy vegetables in Turkey which could to be due to richness of chlorophyll. Sharma et al (2006) reported that Cu concentration (2.25-5.42 mg/kg) in vegetables grown in waste water areas of Varanasi, India were within safe limit. The present study is in agreement with the above findings.…”

Present study describes the extent of heavy metal contamination in two vegetable types viz., cabbage (Brassica oleracea var capitata) and cauliflower (Brassica oleracea var botrytis) sold in urban open markets of Kathmandu valley. A total of 18 vegetable samples collected from various market sites of the valley were analyzed for heavy metals viz., As, Cd, Cu, Hg, Pb and Zn using atomic absorption spectrophotometer (AAS). Results revealed that the metal concentrations in both the vegetables tested were found in the order as Zn>Cu>Pb>Cd. The metal levels in cabbage leaves irrespective of the market sites, ranged between 0.91-2.05 mg/kg for Cd, 14.32-28.31 mg/kg for Cu, 7.29-14.70 mg/kg for Pb and 36.33-108.09 mg/kg for Zn respectively. Similarly, the metal levels in cauliflower varied from 0.81-1.50 mg/kg for Cd, 19.29-26.77 mg/kg for Cu, 10.82-21.23 mg/kg for Pb and 62.45-73.72 mg/kg for Zn respectively. However, As and Hg were found below the detection limits in both the vegetables tested. It was also found that while the mean concentrations of Cd and Pb exceeded the maximum permissible limits for vegetables, Cu and Zn were found within the safe limits as recommended by FAO/WHO. From the present study, we conclude that a regular monitoring of heavy metals in vegetables is necessary for safe consumption as well as to prevent excessive buildup of these metals in the human food chain.

“…Wastewater contains substantial amounts of toxic heavy metals, which create problems [6,[11][12][13]. Excessive accumulation of heavy metals in agricultural soils through wastewater irrigation, may not only result in soil contamination, but also affect food quality and safety [8,[14][15][16].…”

“…In recent years, many studies have carried out about effluents quality and its effect on soil and agricultural crops [7,15,[38][39][40]. The researches indicated paper mill industries not only led to accumulation of toxic elements in soil environment, but also increased the risk of accumulation in crop plants [20,35,37].…”

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill effluent had significant (P < 0.05) effect on EC, pH, OC, Na, Cd, Cr, Cu, Mn and Zn of the soil in both seasons. Insignificant (P > 0.05) changes in WHC and bulk density of the soil were observed after irrigation with paper mill effluent. The agronomical performance of T. foenum-graecum was increased from 5% to 25% concentration and decreased from 50% to 100% concentration of paper mill effluent as compared to control in both seasons. The heavy metals concentration was increased in T. foenum-graecum from 5% to 100% concentrations of paper mill effluent in both seasons. Biochemical components like crude proteins, crude fiber and crude carbohydrates were found maximum with 25% paper mill effluent in both seasons. The enrichment factor (Ef) of various heavy metals was in order of Cd > Mn > Cr > Cu > Zn > Fe for soil and Mn > Cu > Cr > Cd > Zn > Fe for T. foenum-graecum plants after fertigation with paper mill effluent. Therefore, paper mill effluent can be used as a biofertigant after appropriate dilution to improve yield of T. foenumgraecum.
