“…In Pakistan, previously, some researchers reported a level of 1.10 μg g −1 of Cu as per dry weight of fish (Tariq and Jaffar 1993). Previously, some researchers reported 1.62 μg g −1 of Cu in US fish (Gale et al 2004), while in Brazil tilapia fish 1.62 μg g −1 of Cu was determined (Vives et al 2006). In Saudi Arabian fish, the maximum level of Cu was 2.26 μg g −1 as per dry weight of catch (Ashraf et al 2006).…”

“…In the USA, according to one report, a maximum level of 173 μg g −1 of Zn as per dry weight was observed (Gale et al 2004). In Brazil, the level was observed to be 3.36 μg g −1 of Zn as per dry weight (Vives et al 2006). In a report regarding level of Zn in Saudi Arabian fish, 16.15 μg g −1 of Zn as per dry weight was observed (Ashraf et al 2006).…”

“…The value of biological methods to monitor metals within the fresh water environment has been considered of great importance, offering an economic and sensitive way of analysis. Fish are useful organisms to study metal contamination, because they explore freely the different trophic levels of the aquatic ecosystem or microbasin (Swaibuh Lwanga et al 2003;Vives et al 2006).…”

“…For decades, fish species as bio-indicators of heavy metal pollution has been studied by many researchers in a number of countries, including Turkey (Canli et al 2001;Tuzen 2003;Altindag andYigit 2005, Fidan et al 2008), Brazil (Vives et al 2006), Italy (Boncompagni et al 2003;Storelli et al 2005), USA (Heiny and Tate 1997;Gale et al 2004), Saudi Arabia (Ashraf et al 2006), Portugal (Leal et al 1997), Libya (Voegborlo et al 1999), Uganda (Swaibuh Lwanga et al 2003, etc. In Pakistan, a study was previously carried out for the determination of some heavy metals from fresh water fish catch from the River Indus (the longest river in Pakistan and the 21st largest river in the world in terms of annual flow, also considered the lifeline of Pakistan).…”

The untreated industrial and sewage wastes arising from industries and metropolitan activities make their passage to the River Ravi, Pakistan, where Balloki Headworks is one of the major sites of effluent concentration. This study was designed to evaluate the concentration of various toxic elements in fishes of that area compared to a nearby fish farm. The concentrations of heavy metals, such as As, Cd, Cu, Pb, Hg, and Zn, and electrolytes Ca, K, and Na were determined in different edible and non-edible fresh water fish varieties. Fish samples were collected from two selected sites and were analyzed for aforementioned elements. Higher levels of As (35.74-45.33 ppm), Cd (0.35-0.45 ppm), Pb (2.1-3.0 ppm), Hg (83.03-92.35 ppm) while normal levels of Zn (37.85-40.74 ppm) and Cu (1.39-2.93 ppm) were observed. Mercury, higher levels of which trigger cough, impairment of pulmonary function, and psychotic reactions, was significantly higher in all studied categories. At the sites under study, there has been observed alarming levels of toxic metals which are needed to be monitored regularly.
