A pot experiment was conducted to investigate the effect of irrigation water collected from different industrial areas on Red amaranth (Amaranthus tricolor L.) and tomato (Solanum lycopersicum L.). Collected water samples were analyzed for various parameters, which include pH, DO, BOD, COD, P, NH3-N, K, S, Zn, Cu, Pb and Cd. The results were compared with the irrigation water quality standards by the Department of Environment (DoE) of Bangladesh and many of them were found several-folds higher than the permissible limit. The deterioration trends of the water samples are as follows: Tejgaon canal > Rampura canal > Sitalakhya river. Dry matter of vegetables grown on Tejgaon soil was significantly (p ? 0.05) higher than that of agricultural soil. Both red amaranth and tomato grown in Tejgaon soil accumulate highest concentration of heavy metals followed by Rampura and Sitalakhya soil. The concentrations of zinc (Zn), lead (Pb) and cadmium (Cd) in edible portions of both vegetables were found several times higher than the WHO prescribed permissible limits. The concentration of heavy metals in vegetables were found in the order Zn > Cu > Pb > Cd.Bangladesh J. Sci. Res. 28(2): 151-159, Dec-2015

Surface Water Samples

Nationwide surveys of 1,4-dioxane and methyl-t-butyl ether (MTBE) levels in raw water used for the drinking water supply were conducted at 91 water treatment plants in Japan in 2001 and 2002, prior to the revision of the drinking water quality standards. 1,4-dioxane was widely and continuously detected in raw water samples and its occurrence was more frequent and its concentrations higher in groundwater than in surface water. However, its maximum concentration in raw water was much lower than its new standard value (50 μg/L), which was determined as a level of 10−5 excessive cancer risk to humans. Trace levels of MTBE were also detected in several surface water samples.

The paper presents a new methodology for establishing regional water quality standards for the Upper Kama water bodies. Water bodies of the Upper Kama Basin are receiving wastewater from one of the largest industrial complexes of the Kama basin – Solikamsk-Berezniki industrial hub. The approach takes into account factors that determine the content of heavy metals in natural waters and the spatial/temporal variability of their content in the water bodies of the Upper Kama basin. The developed approach is implemented in establishment of regional water quality standards for the Upper Kama basin.

This paper explained heavy metals and chemical properties from the Cisadane River in Tangerang City. A survey method was used to determine the place for sampling the test material. Water measurement is carried out in situ and laboratory tests. Data retrieval was done by purposive sampling determining three observation stations, namely in the Taman Gajah Tunggal park area (station1), Babakan Cikokol residential area (station 2), and Karawaci paper mill area (station 3). The analysis was carried out exactly using analysis. Namely, analysis carried out in the laboratory. The parameters observed were COD, phosphate, DO, BOD, pH. Results of this study informed the water quality in the Cisadane City river did not meet Class II Water Quality Standards based on Government Regulation Number 82, the year 2001. The COD content only meets class II water quality standards at stations 1 and 3. BOD and phosphate content is high and exceeds class II water quality standards. Heavy metal content still meets the water quality standard threshold with a value of Cd less than 0.01 mg/L, Cu less than 0.02 mg/L, Pb less than 0.03mg/L, and Cr less than 0.05mg/L. Zn content exceeds the water quality standard threshold at station three and meets water quality standards at stations 1 and 2 with a value of less than 0.05mg/L.

The Many

In industrial areas the waste water from the high concentration of population and heavy industry can cause overload of relatively small rivers. Uniform emission standards for the discharges are inappropriate even in these areas as variations in river flows would make a uniform standard too relaxed or too stringent, according to circumstances, at different points. The problem of fixing river quality standards which would allow fish to repopulate the industrial rivers in Yorkshire and then of applying them to produce appropriate standards for effluents has been examined by a group from the Yorkshire Water Authority. Provisional river water quality standards are recommended in different forms and the bases for these are discussed and comparisons made with the field measurements of river water qualities and the presence of fish. The standards are suggested as mean or median or 95 percentiles as appropriate and also in some cases as maxima which should not recur more often than a critical period if fisheries are to be self sustaining. Methods for applying them to the many effluent discharges in the industrial areas of Yorkshire are also discussed.

The growth in United Kingdom salad production is dependent on irrigation to maintain product quality. There are concerns that irrigation with poor-quality water could pose a disease risk. This article examines the key issues in the emerging debate on the microbiological quality of water used for salad irrigation in the United Kingdom. The links between irrigation water quality and foodborne disease, and the current international guidance on irrigation water quality, are firstly reviewed. The findings indicate that a number of recent food-poisoning outbreaks have been linked to the consumption of fresh fruits and vegetables and that unhygienic product handling is implicated as the principal source of contamination. There is also credible evidence that salads contaminated in the field, including by irrigation water, can pose a small disease risk at the point of sale. Although irrigation water–quality standards exist in various forms internationally, there is no nationally agreed on standard used in the United Kingdom. This paper then describes the results of a survey conducted in 2003 of United Kingdom irrigation practices that might influence the microbiological quality of salads. The survey showed that surface water is the principal irrigation water source, that overhead irrigation predominates, that the gap between the last irrigation and harvest may be <24 h in many cases, and that current water-quality monitoring practices are generally very limited in scope. This paper concludes with a discussion of the issues emerging from the review and survey, including the need for improved water-quality monitoring, and the problems associated with establishing water-quality standards that could be either too strict or too lax.

Area Of Study

The groundwater is considered as essential resources for Irrigation in Misurata city, this type of Irrigation suffered to some problems affecting their quality. The aim of this study was to evaluate, a physiochemical and biological parameters of wells water in Misurata Area during the period between November 2016 to December 2018. The area of study about 70 Km distance between Tawarq and Eldafina was divided into eight lines per appendicular to sea cost. Five water sample were taken for each line, in which the distance about 20 Km between each line. The pH, SO4, HCO3, Ca, and D.O were within the permissible levels a according to FAO standard as well as, SAR, RSC, SSP were acceptable while EC, TDS, Cl-, K+ and Mg++, were higher than the standard, moreover, the temperature, was normal in all the samples. The heavy metals values of Fe, Mn, Zn and Cu were within the standard. In general, the results showed that high values of EC, TDS, Cl-, and Mg++ were the main reasons which lead to the deterioration of water irrigation. Therefore, the water was inadequate for agricultural purpose without any treatment such as desalination to reduce the salinity, Also the results of microbiologic analysis showed a contamination in most sample.

Statistical Work

This study is based on an analysis of drinking water at Koya city, Kurdistan-Iraq. Since the source of tap water comes either from Dokan Lake or from groundwater resources. Therefore, ten samples from houses tab water of Koya city and ten samples from well-known brands of bottled water were collected. Concentrations of the metals in such water samples were analyzed by X-ray fluorescence and compared with WHO water quality standards for minerals. The experimental results show that most elements detected in this study were within the guidelines given by WHO for drinking water, while four elements of Ca, Al, Mg, and Cr were identified as risky elements in developing diseases since their level exceed the WHO standard levels. Positive relationships between risky elements and some serious diseases were discussed. Statistical work shows that elements; Ca, Al, and Cr have a high risk while Mg has a low risk.
