Samples of the muscle of two species of tilapia (Oreochromis mossambicus and O. niloticus; 17–20 cm length) were obtained from at least one reservoir in each of the six river basins (Aruvi Aru, Kala Oya, Kirindi Oya, Ma Oya, Mahaweli, and Walawe Ganga catchments) in Sri Lanka. The metals Ca, Cu, Fe, K, Mg, Mn, Na, and Zn were consistently detected...

Samples of the muscle and liver of the Nile tilapia (Oreochromis niloticus) were obtained from a single reservoir in each of three Sri Lankan catchments (Kaudulla, Rajanganaya, and Udawalawe reservoirs in the Mahaweli, Kala Oya, and Walawe Ganga river basins, respectively) in 2002. The concentrations of 12 elements were consistently detected in the...

Copper (Cu) is an important heavy metal to be considered in soil contamination, because high concentrations of copper in soil produce toxic effects and may accumulate in plant tissues. In Australia's oldest sewage irrigation farm, located in Werribee, Victoria, soil in the land filtration area is contaminated by Cu. However, Cu content in herbage t...

Australia is a water-stressed nation and demand on potable water supply is increasing. Consequently water conservation and reuse are increasingly becoming important. Irrigation of recycled wastewater on water repellent soils is a technology that is being trialled as a means of improving crop production and conserving potable supply. However, recycl...

Copper is an important micronutrient and trace amounts are essential for crop growth. However, high concentrations of copper will produce toxic effects. Australia is increasingly developing production of crops in water repellent soils. Clay amendment, a common amelioration techniques used in Australia, has demonstrated agronomic benefits in increas...

A pulse of chromated copper arsenate (CCA, a timber preservative) was applied in irrigation water to an undisturbed field soil in a laboratory column. Concentrations of various elements in the leachate from the column were measured during the experiment. Also, the remnants within the soil were measured at the end of the experiment. The geochemical...

The movement of copper, chromium and arsenic originating from samples of the wood preservative Tanalith® through mildly acidic, sandy loam soil was investigated. Small, undisturbed soil cores (of dimensions 15 × 15 × 15 cm) were removed from the topsoil of a paddock adjacent to the Glenelg River in the Western District of Victoria, Australia. The p...

This paper investigates leaching of water and nutrients (NO‐ 3, Cl‐, PO3‐ 4) from the unsaturated layer in an Australian soil using a multisegment percolation system (MPS). Large undisturbed soil cores were collected from a clay‐based, basaltic plain, agricultural soil at Grassmere, 300 km west of Melbourne, Australia. Significant heterogeneity (or...

... Thus, the result shows that 10% of the world's population consumed food produced in lands irrigated with wastewater during the early 90's (Smit & Nasr, 1992). The use of wastewater in irrigation is more and more regarded due to the lower cost technical solutions for decreasing soils degradation, and also for intoducing new nutrient elements into the soil (Kiziloglu et al., 2008;Yadav et al., 2002;Xiong et al., 2001). ...
... For all the studied micronutrients (Fe, Mn, Zn and Cu), the exchangeable and carbonate fractions were the lowest ones. This is in agreement to the results of Li et al. (2006) for Cu, who found that the exchangeable and carbonate fractions of Cu in soil at a farm, irrigated with sewage sludge in Australia, were very low, only comprising 3.49e5.49% of the total Cu. Similarly, Nazif et al. (2015) found that the fraction of exchangeable Zn in cultivated calcareous Fig. 4. Proportion (%) of Cu fractions of the studied soils determined by fractionation to the different soil layers (0e20), (20e40) and (40e60) (S1-S12: soil samples). ...
... where, EDI is the estimated daily intake (mg/kg bw/day), MC is the metal concentration in fi sh muscle (mg/kg wet weight), IRd is the daily average fi sh ingestion rate (kg/day) and BW is the average body weight for an adult. In Sri Lankan context, the IRd for fi sh was taken as 0.060 kg/day (Allinson et al., 2009;2010). Average body weight of an adult was considered as 70 kg (the USEPA default value). ...
... In the case of nutrients, leaching losses also represent a decline in soil fertility with economic consequences, [4,5]. Owing to the toxicity of pesticides and industrial wastes, even small quantity when present in soil can be transported to the groundwater which can make them persistent for several hundreds of years [6][7][8][9][10]. ...
... Multiple sample percolation systems are an excellent means to obtain accurate values of the solute and water flux in vadose zone experiments and have been shown to effectively represent the impacts of soil heterogeneity on these fluxes [10]. Using this apparatus, an experiment was recently conducted to investigate the impacts of soil structure on nutrient transport in an agricultural soil typically found in Victoria, Australia [11]. The data from this experiment is used here to compare and contrast two approaches to modelling solute transport in the unsaturated zone. ...
... Meanwhile, the levels of Mn found in feathers of Gentoo penguins (9.15-23.65 μg g − 1 , Table 2) were much higher than those reported by Burger et al. (2008) in feathers of Arctic seabirds (0.75-1.10 μg g − 1 ). It seems to sustain a potential increase of Mn pollution in Antarctica as also noted by Jerez et al. (2011), probably due to the use of Mn as additive to fuels in the last decades (Burger and Gochfeld, 2000;Mispagel et al., 2003). ...
... As a approaches 0, surface site heterogeneity increases, and as a approaches 1 surface site homogeneity also increases. The relative sorption capacity (RSC) was also used to compare the metal sorption capacity of the samples (XIONG et al., 2005). The RSC can be calculated by taking the difference between the initial and equilibrium metal concentrations, then dividing this difference by the initial metal concentration, and then expressing this as a percentage: ...
... Copper containing effluent is produced in many metal processing industries for example in the manufacturing of printed circuits, fuel pipes, gutters, roofing sheets and pipes for fuel. About 1,400,000,000 pounds of copper were released into the environment by industries in 2000 (Kratochvil et al., 1998;Mao et al., 2004). ...
... To study the effect of biopolymer-bentonite composite addition on heavy metal adsorption by soils, a procedure (Xiong et al. 2005;Tsadilas et al. 2009;Uchimiya et al. 2011;Li et al. 2016;Bogusz et al. 2017) similar to the aqueous system was followed. To 1 g soil, 0.05 g chitosan-bentonite composite was added, and the mixture was incubated for a fortnight at room temperature (25°C). ...
... Fish carry out all life processes in water, thus taking in metals by ingestion of suspended particulate materials in water, feeding, ionic exchange between fish and it's environment and adsorption on tissue and membrane surfaces [2]. ...
