“…The Pb level in liver among all months varied significantly (P < 0.05) and ranged from 1.61 ± 0.25 µg/g dw in June to 4.59 ± 0.38 µg/g dw in August, with average 2.71 ± 1.05 µg/g dw (Table 3), this value is less than the result obtained by Shinn et al (2009) where the value 5.47 µg/g dw liver concentration was calculated for wet weight and was converted to dry weight by multiplying by a factor of 5.88 (Yap et al 2004). The highest Pb levels in gills and muscle were in February compared with other months (2.50 and 1.94 µg/g dw, respectively), and the average was 1.04 and 0.48 µg/g dw, respectively.…”

In recent years, many studies have stated the nutritional benefits of fish consumption: vitamins, proteins and omega-3 fatty acids, which may protect humans from adverse health effects, including heart disease and stroke. This study aimed to evaluate the concentration of Cu, Pb and As in the liver, gills and muscles of tilapia fish (Oreochromis niloticus) and to calculate the weekly intake from eating tilapia collected from Cempaka Lake, Selangor -Peninsular Malaysia during the period between April 2009 to February 2010. The elemental concentrations were determined using inductively -coupled plasma mass spectrometry (ICP-MS). The results showed that all heavy metal concentrations were significantly different among fish organs, and between calendar months. The data showed that Cu levels in liver, gills and muscles were 491.30, 3.70 and 1.82 µg/g dry weight (dw), respectively. Meanwhile Pb levels were 2.71, 1.04 and 0.48 µg/g dw, respectively and As levels were 6.26, 4.18 and 1.79 µg/g dw, respectively. Significant changes occurred in Cu, Pb and As levels in tilapia fish organs in Cempaka Lake over the period of 11 months. Tilapia weekly intake was calculated based on mean Cu, Pb and As concentrations in the muscle of tilapia fish and adult consumption of tilapia in Malaysia which averages at 160 grams per day. Furthermore, tilapia weekly and daily human intakes for Cu, Pb and As were compared with the Provisional Tolerable Weekly Intake (PTWI) established by the JECFA (WHO/FAO) presenting values below the PTWI. Metal levels in fish muscle were found to be lower than the maximum permitted concentrations recommended by various authorities; hence, consumption of tilapia fish from Cempaka Lake is currently safe for humans.

“…As such it is potentially one of the most valuable tools for identifying and quantifying the impact of metals in aquatic environments (Borgmann and Norwood, 1994;Birungi et al, 2007;Shinn et al, 2009;Allert et al, 2009;Otero-Muras et al, 2010). This impact has been widely investigated in studies examining accumulation in sediments (Rosales-Hoz and Carranza-Edwards, 1998), crustaceans (Zou, 1997;Steenkamp et al, 1994), aquatic insects (Hall et al, 1998), amphipods (Borgmann and Norwood, 1994), mammals associated with water (Gutleb et al, 1998), aquatic macrophytes (van der Merwe et al, 1990), algae (Carr et al, 1998), plankton (Ghatak et al, 1987) and several species of fish (Maage, 1990;Sultana and Rao, 1998;Ward and Neumann, 1999;Annune et al, 1994;Lange et al, 1993;Neuman et al, 1991;Prasath and Khan, 2008).…”

This is the first paper reporting on results obtained in a metal bioaccumulation study in the Vaal River system. It discusses concentrations of four non-essential elements (strontium, aluminium, lead and nickel) in water, sediment and various fish tissues. A second paper will report on concentration levels of the remaining five essential trace metals (chrome, copper, iron, manganese and zinc) studied. While heavy metals did accumulate in C. gariepinus tissues, no clear trends emerged with regard to differences between localities (Vaal Dam and Vaal River Barrage) or surveys. The highest non-essential element metal concentrations were generally recorded in gill (filaments and arches), followed by muscle, liver and lastly skin. This general trend appears to be in agreement with trends observed by other workers and reported in the literature. Variability in tissue metal concentrations in C. gariepinus within locality and seasons observed in this study is also reflected in results from available literature. This accentuates the importance of factors that influence the concentrations and bioavailability of trace metals.

“…Among them, P. anatolicus, A. akili and G. gobio microlepidotus are also endangered and endemic species from Turkey. The liver is the main site of accumulation, biotransformation and excretion of pollutants in fish (Shinn, 2009). However, the muscle is the section of fish that is consumed by human.…”
