“…The elevation in zinc level during autumn may be attributed to the increasing amounts of industrial, agricultural and domestic wastes at the sampling areas with low water levels and leaching of fertilizers residues used in the agriculture operation into the aquatic environment. Results were nearly similar with that obtained by Ibrahim & Omar 2013and Goher et al (2014); and differed with Zayed et al (1994) whom recorded the highest level of zinc during winter and the lowest during autumn.…”

INTRODUCTION Damietta Nile Branch receives a large amount of untreated effluents from agricultural domestic and partially treated industrial wastewater. Contamination of water is a serious environmental problem as it adversely affects the human health and the biodiversity in the aquatic ecosystem (Sabae & Rabeh, 2007). El-Bagouria Canal (Fig. 1) is diverting from El-Monofy Rayah, It extends along the middle of Kafr El-Zayat Center (El-Gamal, 2009).

In this study concentrations of heavy metals, such as Cd, Co, Cu, Fe, Mn, Ni, Pb and Zn were determined in water, sediment, muscle, liver and gill of fish (Silurus triostegus, Mastacembelus simack, Mystus halepensis, Orthrias euphraticus) the muscle and liver of crab (Potamon fluviatilis), the internal organs of fresh water snail (Physa acuta), and mussel (Unio elongatulus), and in whole biomass of green algae (Spirogyra sp.) examples collected seasonally from three selected sites (I, II, and III) of Tigris River and from a reference site on Resan Creek. In general, the average Cd, Cu, Mn, Ni, Zn, and Fe values in Sites I, II, and III were found to be high in spring and summer. The concentrations of heavy metals in the Tigris River are compared with previous studies in the same sites. The results showed that Cu levels have gradually decreased during recent years. In Tigris River, among the living organisms, i.e., those which are living in benthic region and showing biomonitor characteristic, crab, snail, green algae, mussel and fish are seen to be formed in sequence. Cu, Fe, Mn and Zn values obtained from the muscle of fish and from the mass of internal organs of mussel and snail were found to be under the acceptable values suggested.

“…These changing parameters influence the bioavailability of biogenic elements. Most of the studies report the highest concentrations of biogenic elements in fish in the summer, and they mostly relate these concentrations to water temperature [59,71,81,82]. Fish with increasing ambient temperatures increase their metabolic rate [83].…”

“…Fish with increasing ambient temperatures increase their metabolic rate [83]. Zayed and Eldien [81] found the highest metal contents in fish during the summer, which suggested that it was due to a higher rate of breathing and lower oxygen content in water. The metabolic rate was responsible for the highest concentrations of Cd, Cu, Pb, Fe, and Zn during the summer in marine fish [82].…”

Aquatic organisms are exposed to a complete mix of elements. The accumulation of elements in organisms often reflects the amount of these elements in the surrounding environment, especially in the water environment, where the elements are easily spread [1, 2]. In studies where the concentration of metals in different lakes increased in gradient, the accumulation of metals increased in the juvenile perch transplanted up the gradient and the opposite down the gradient [3]. The accumulation of elements in fish depends on environmental factors such as temperature, pH, dissolve organic matter, and salinity [4-6]. These physicochemical parameters often change with the season, and thus season affects the bioavailability and accumulation of elements in fish [1]. Biological factors such as age, size, and weight of individuals, sex, reproduction cycle, feeding, and habitat use also play an important role in the accumulation of elements [2, 7-10]. The accumulation and the beneficial or toxic effects of elements depend on element properties. In general, elements are categorized into biologically essential and non-essential. Biogenic elements are integral components to support the function of an organism [11]. However, the concentration and accumulation of these elements account for the
