“…Several studies have demonstrated that high concentration of heavy metals in water and sediments of rivers can considerably decrease the number of macroinvertebrates, thus affecting entire aquatic life chain (Roline 1988). Furthermore, the presence of metals and metalloids in water can be accumulated in fish as was demonstrated with intentional exposure of sub-lethal concentrations of heavy metals in common carp (Vinodhini and Narayanan 2008).…”

New technologies and higher prices of raw materials have promoted the expansion of mining activity throughout the world; if not properly regulated, this activity can lead to contamination of the local and regional environment. The city of Cerro de Pasco is located close to a large open-pit mine and in recent years, several reports have provided evidence of environmental contamination and related health problems. The aim of this paper is to evaluate the contamination in fluvial water, sediments and biological fluids from this area. The collective results show elevated metal and metalloid concentrations in rivers and sediments, especially in the areas downstream of the mine. For instance, Pb concentration in rivers downstream of the mine was 4.451 mg/L, while it was 0.037 mg/L upstream of the mine. Sediments also show higher concentration of metals and metalloids in the areas under the influence of the mine. Concentrations of elements in human blood were measured in the population of Paragsha, a village close to the mine. Analysis of the blood samples revealed elevated levels of metals and metalloids, particularly Pb, Cr, Al, Ni and Mn. All of the studied population showed blood concentrations of Al, Cr and Ni higher than those recommended by the WHO. The high concentration of elements found in the blood of the population could be related to the high concentration in the surrounding water sources, but further studies are required to determine the exact sources of exposure to these metals and metalloids.

“…Among aquatic animals, fishes are widely used to evaluate the health of aquatic ecosystems because pollutants build up in the food chain and are responsible for adverse effects and consequent death [7,8]. In this study, the concentration of metals in fish (Catla catla and Labeo rohita) organs (liver gill and muscle) were used to calculate Bioaccumulation Factor (BAF).…”

This study was conducted during March to May of 2010 dry season, giving prime thrust to determine the metal concentrations in commercial fish species of Catla catla and Labeo rohita, collected from various points along the river Cauvery. The liver, gill and muscle tissues of fish were analyzed for Fe, Pb, Zn, Ni, Mn, Cu, Cr and Cd using Atomic Absorption Spectrophotometry (AAS-model: 6300). The Catla catla has shown more accumulation potency for all the metals than Labeo rohita. The liver in both fish species has better accretion capacity compared to gill and muscle and the same was noticed by bioaccumulation factor. The results of bioaccumulation factor were in the order of Ni > Zn > Cu > Mn > Fe > Cr > Pb > Cd. Elevated trend was noticed among the essential metals and decreased trend among the nonessential metals were observed in both fish species.

“…Metals are non-degradable and accumulate in animals, damaging the nervous system and internal organs (Lee et al, 2007). Therefore, research on metal contaminants is important owing to their potential toxicity to fish (Vinodhini and Narayanan, 2008). Mucus is continuously sloughed in the gill to maintain normal functioning (Eddy and Fraser, 1982).…”

Acute toxicity estimates of copper (Cu) and zinc (Zn) in juvenile Chinese sturgeon were studied in the Yangtze River estuary and using the static test method to assess Cu and Zn toxicity. The results showed that Cu was more severely toxic to Chinese sturgeon than Zn. The Cu LC 50 after 24-, 48-, 72-and 96-h , respectively. The liver was the major accumulation site for Cu. Cu content in the liver of juveniles in the control group (no Cu) was the highest, followed by the gills, whereas the lowest content was detected in cartilage. The fastest accumulator of Cu was the liver, followed by the stomach, and cartilage and skin had the lowest contents. Superoxide dismutase (SOD) and catalase (CAT) activities in the liver tissues of juveniles were relatively low for the first 24 h, but the activities recovered gradually from 24 to 48 h and decreased after 48 h to levels lower than the contro1 group. These changes in SOD and CAT activities indicate that juvenile Chinese sturgeon were severely affected by Cu. These data show that Chinese sturgeon juveniles face the threat of Cu contamination and this alerts officials to the dangerous situation.
