The present study has been carried out by irrigating turnip plants with different concentrations of treated municipal wastewater in order to see the effect on heavy metals accumulation and growth of plants. The turnip plants were watered with normal water and the results compared with results obtained by using treated municipal wastewater. The treatments used were: control (tap water) with 0, 25, 50 and 75% wastewater, and 100% wastewater, in three replications. The results indicated a substantial build-up of heavy metals in turnip irrigated with wastewater. The heavy metals content in the dry matter of the plants increased significantly with increase in wastewater concentration. Analysis of plant samples indicated the maximum accumulation of Fe (1,835 mg/kg in roots and 1,247 mg/kg in leaves) followed by Mn, Zn, Ni, Cu and Cd. The findings of this study regarding daily intake of metals suggest that the consumption of plants grown in wastewater is high, compared to consumption of those grown in tap water, but is nearly free of risks.

<div> <p>Two greenhouse pot experiments were conducted in Agrinion, Greece. The impact of treated municipal wastewater (TMWW) and sludge (i) on the growth of <em>Lactuca sativa</em> L. var Longifolia (lettuce) and (ii) on the extent of soil pollution with heavy metals was studied. Soil pollution was assessed by calculating the Pollution Load Index (PLI). Both of these experiments were conducted, using a randomized block design in four replications and seven treatments, respectively, as follows: (a) Experiment A: study of the effect of treated municipal wastewater (TMWW): [Control, 20%, 40%, 60%, 80%, 100%, (100%+30 t/ha Sludge)] and (b) Experiment B: Study of the effect of sludge (t/ha): 0, &nbsp;6, 12,&nbsp; 18, 24 , 30, (30+100%TMWW). The sludge affected significantly plant height and fresh and dry matter yield, as well as the dry matter N content of plants, while the TMWW affected significantly the dry matter yield and non-significantly the plant height. The pollution load index (PLI) was non-significant for both treatments (sludge and TMWW). According to PLI calibration scale, the soil was found to be slightly polluted with heavy metals under both treatments.</p> </div> <p>&nbsp;</p>

: Heavy metals (HM) can enter the human body via food chains or contaminate groundwater resources. The current study aimed to investigate HM contamination in vegetables and its associated health index risk (HIR) in Isfahan, Iran. The lowest amount of HM was observed for Cd and Pb in all vegetables. The highest level of Cadmium content was found in potato (1.153 mg kg-1 dry matter (DM)) and spinach (1.180 mg kg-1 DM). The highest levels of As and Cu were observed in lettuce, while the lowest content of Cu was in the carrot. Moreover, the highest content of N (344.00 mg kg-1 DM) was obtained in spinach. The As and P were higher than standard amounts, and HIR was higher than 1 for these two elements. Heavy metal's HIR through ingestion vegetables were a great concern, and there has been particularly increased attention to As. A great understanding of the ecological effects of HM on soils and vegetables is needed to develop management options.

Concentration Levels

Most of the industrial sewage effluents used for irrigation contains heavy metals which cause toxicity to crop plants as the soils are able to accumulate heavy metal for many years. The vegetables grown for the present study were irrigated with treated wastewater brought from a nearby full-scale sewage treatment plant at different compositions along with tap water as a control. The concentration levels of the Cd, Co, Cu, Mn and Zn in the soil were found to below the toxic limits as prescribed in literature. Daily Intake Metals (DIM) values suggest that the consumption of plants grown in treated wastewater and tap water is nearly free of risks, as the dietary intake limits of Cu, Fe, Zn and Mn. The Enrichment Factor for the treated wastewater irrigated soil was found in order Zn> Ni> Pb> Cr> Cu> Co> Mn> Cd. Thus, treated wastewater can be effectively used for irrigation. This will have twofold significant environmental advantages: (1) helpful to reduce the groundwater usage for irrigation and (2) helpful to reduce the stress on surface water resources.

The heavy metal concentration (e.g., Mn, Zn, Pb and Ni) were determined in soft tissues and shells of freshwater mussels (Lamellidens marginalis) at the various sites of Dhanmondi lake, Dhaka, Bangladesh between the period April, 2010 and March 2011. The heavy metal concentrations in shells and soft tissues of freshwater mussels were tended to vary significantly among sampling points and seasons in Dhanmondi Lake. Distribution of heavy metals in shell and soft tissue of Lamellidens marginalis followed the order Mn>Zn>Pb>Ni, respectively. According to the t-test, level of manganese, zinc and lead under investigation between shell and tissue showed statistically significant differences [Mn: t=-11.387; df=16; P=0.000; Zn: t=-2.590; df=16; P=0.020 and Pb: t=-2.8679; df=16; P=0.011].
