“…Active metabolic tissues, such as the kidneys, gills, and liver, accumulate more heavy metals than less metabolically active tissues, such as the muscles and skin (Ali et al, 2019). Generally, muscles store the lowest amount of heavy metals (Ronagh et al, 2009). These results are nearly similar to those reported by Badr et al (2014), who concluded that the level of heavy metals in Nile Tilapia tissues were higher in the liver than in gills and muscle.…”

Despite wide studies of biomonitoring aquatic environment through dynamics of host–parasite interaction, bio-indicators to track the influence and accumulation of heavy metals on fish are still few. The present study sheds light on the relation between fish parasites and heavy metals as it threatens fish’s health and, as a consequence, that of humans after fish consumption. Samples of Nile tilapia (Oreochromis niloticus) were collected in Burullus Lake, a wild fish source, and from a private fish farm in Kafr El-Sheikh Governorate, in Egypt. They were exposed to various pollutants associated with anthropogenic activities to determine the levels of accumulation of Fe, Zn, and Cu, along with the top three most toxic metals (As, Cd, and Pb) in water and fish tissues of gills, intestine, liver, and muscles in both wild and farmed O. niloticus. The results showed the order of abundance: Fe < Zn < Pb < Cu < As < Cd. In waters of both farmed and wild fish, there was a significant negative relation between parasite prevalence and heavy metals, including Zn, Pb, and As. Also, there was a significant positive relation between parasite prevalence with Cu while no significant relation was found with Fe and Cd. Heavy metal content was significantly higher (p > 0.05) in non-infected than infected farmed and wild O. niloticus. In addition, a significantly decreased concentration (p > 0.05) of essential heavy metal was recorded in wild fish compared to farmed specimens, while non-essential heavy metal was significantly higher (p > 0.05) in wild compared to farmed fish. Bioaccumulation factors (BAF) of different organs of O. niloticus were ranked in ascending order: Liver > Gills > Intestine > Muscles. In general, the risk assessment showed safe human consumption of farmed and wild fish under the reported environmental conditions in this study. Moreover, the parasite's presence can be adopted as a surrogate indicator to estimate the potential impact of heavy metal pollution and accumulation.

“…Fish muscle is chosen as it is the part which is consumed by people (Agusa et al 2005;Zauke et al 1999), Muscle, generally, accumulates the lowest level of heavy metals (Ronagh et al 2009). In order to compare dry weight values (present study) with wet weight values of other studies, a conversion factor of 5.88 (1/0.17) was applied (Yap et al 2004).…”

“…The Cu level in gills and muscle was the highest in fish collected in August 7.27 ± 2.78 and 3.40 ± 0.76 µg/g dw, respectively, whereas Cu level in gills and muscle was the lowest in fish collected in April, which were 1.41 ± 0.06 and 1.28 ± 0.05 µg/g dw, respectively (Tables 4, 5). Meanwhile, previous studies have reported Cu levels of 2.07 µg/g dw in fish muscle (Ronagh et al 2009), 0.76 to 12.52 µg/g dw in muscle of 15 fish species from Lake Chini, Pahang, Malaysia (data converted to dry weight) (Ahmad & Shuhaimi-Othman 2010 …”

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.

“…These factors include; i) the season, ii) decomposing trace metal -containing organic matter content, iii) lowering of pH, iv) changing redox conditions, v) increased salt conditions (Stumm and Morgan, 1996). Concentration of metals in sediments is dependent on the season to some extent according to a study by Ronagh et al (2009). The authors showed that the differences in sediment-metal concentrations among different seasons were not significant (p>0.05) though the variations showed higher concentration in the summer season than other seasons.…”

“…Fish are widely used as biomonitors as they are at the top of the food chain in aquatic ecosystems and hence tend to bioaccumulate high concentrations of toxins from the environment through the process of biomagnification (Ronagh et al, 2009). Biomonitors are organisms that generally accumulate heavy metals to concentrations that are relatively easy to measure since they concentrate the metals over several orders of magnitude above ambient water levels (Sarkar et al, 2008).…”
