Levels of five heavy metals [copper (Cu), lead (Pb), cadmium (Cd), chromium (Cr) and nickel (Ni)] were evaluated in liver and muscle tissues of fish (Mugil auratus) collected from the Black Sea at Sinop-Icliman, Turkey. Sampling and analysis methods are described. Variations of heavy metal concentrations with seasons are discussed. Cr and Ni concentrations were below the limits of detection (<0.05 and 0.1 ug/g dry weight) in all tissues and seasons. Cu, Pb and Cd were detected within these limits, as mg/kg dry weight, in liver tissue: 0.49-1.30, 0.60-1.21 and 0.15-0.50, and in muscle tissue: 0.30-1.00, 0.57-1.12 and 0.10-0.40, respectively. Cu, Pb and Cd concentrations in these tissues were elevated and the highest heavy metal concentrations were found in the liver. While Cu, Pb and Cd concentrations were highest in fish tissues collected in August 2000, the lowest concentrations of these metals were observed in fish tissues collected in May 2000. Pb had the highest level observed in fish tissues. According to the Turkish Food Codex Regulation's residue limits, the cadmium level determined in fish tissues was high (0.1 mg/g) and the lead level, especially in liver tissue, was high in August (1 mg/ g), while other metals (Cu, Cr and Ni) were within the maximum residue limits.

A comparative analysis about the accumulation of heavy metal, natural and technogenic radionuclides from the Black Sea environment in different Bulgarian coastline regions is made. The possibilities to use Chlorophyta and Rhodophyta algae phylums as bioindicators in marine environment are investigated. Environmental contamination in the Black Sea alga species (green and red) was studied from 1992 to 2003. Sampling sites were selected to cover the whole coastal region. Low level gamma spectrometry was used to determine the natural and technogenic nuclide concentrations. The heavy metal concentrations were measured by Atomic Absorption Spectrometry (AAS). The obtained data show that radionuclide and metal concentrations depend on the macrophyte type. Tendencies in the concentration of pollutant variations during the studied period are examined and all data give information about different macrophytic species' ability to accumulate certain elements from one and the same sampling location. All obtained results show that use of macroalgae in marine environmental monitoring reduces the need for complex studies on chemical speciation of aquatic contaminants and makes algae valuable indicators for seawater quality assessment. All data show the lack of serious pollution along the Bulgarian Black Sea coast.

Abstract Water quality parameters were measured in Acı Lake. The measurements were carried out in water samples taken from five different stations over ten months. According to the results of the analyses done on the samples of water, without taking into consideration the differences of seasons and stations, the average annual values of heavy metal concentrations for Cr, Cu and Ni were found to be 0.10 mg/l, 0.11 mg/l and 0.19 mg/l dry weight, respectively. Surprisingly, Co and Cd metals were not detected at any station or at any season. Other water quality parameters, namely pH, turbidity and nitrate, fall in the intermediate value range for these measures. The comparisons of the measured parameters and the metal concentration with the water quality index show that the water quality of Acı Lake prevents the water being used as irrigation water due to high salt levels.

Background. The potential toxicity of metals in water may have detrimental effects on the biochemical processes of aquatic organisms, especially fish, which serve as a source of protein in the protein-deficient Nigerian diet. Objective. The present study aimed to determine the concentration of heavy metals in African catfish (C. gariepinus) and investigate the health risk associated with heavy metals in fish. Methods. Heavy metal concentrations in the water samples were determined using atomic absorption spectrophotometry (AAS) and particle induced x-ray emission spectroscopy (PIXE) for sediment and fish tissues/organ samples. Results. Mean nickel (Ni) concentrations differed significantly (p&lt;0.05) by sample type in both the dry and rainy seasons. Similarly, during the rainy season, mean lead (Pb) concentrations in all of the samples from Osogbo differed significantly (p&lt;0.05) by type, with the highest concentration in fish muscle (10.11±1.21 μg/kg) and the lowest Pb concentration in pond water (1.72±0.05 μg/L). Mean chromium (Cr) concentrations of samples from the Ewuru/Rara stream in Yakoyo also differed significantly (p&lt;0.05) by type, with the highest concentration in fish muscle (113.10.±10.07 μg/kg) and the lowest concentration in pond water (3.31±0.22 μg/L). Discussion. Heavy metal concentrations in pond and stream sediment samples revealed transport and deposition processes where trace metals are deposited and incorporated into sediment after entering the aquatic system. Iron (Fe) had the highest concentration levels ranging from (196.21 μg/g – 698.65 μg/g) in the three locations investigated, while Pb levels were the lowest, ranging from (9.05 μg/g – 75.30 μg/g). Conclusions. In general, the concentrations of Cr, copper (Cu) and manganese (Mn) were below standard guidelines, while the concentrations of nickel (Ni) and lead (Pb) were fairly higher than the tolerable limits for water pollution standards.

Ectoparasites and heavy metal pollution pose health risks to both wild and aquaculture fish species. Here, we examine the ectoparasites of fish species (Hemichromis fasciatus, Liza falcipinnis and Sarotherodon galileus) from Abalama and Ilelema locations of the Buguma Creek, Rivers State, Nigeria, over a period of six months (February to July, 2020). Fish tissues (muscles, gills and gut) were also examined for heavy metals (Cr, Cd and Pb). Parasitological investigations were done following standard procedures, as well as the heavy metal analysis which was done using atomic absorption spectrophotometer after dry ashing-acid digestion. Two ectoparasites were isolated: Zeylanicobdella arugamensis from L. falcipinnis at both locations and Cymothoa exigua from H. fasciatus at Ilelema. In surface water, Cr concentration was <0.003µg/l throughout the study period; Cd concentrations ranged between 0.06µg/l and 0.09µg/l at both locations, while Pb values were 0.29µg/l - 0.64µg/l at Abalama, and 0.56µg/l – 0.71µg/l at Ilelema. These values were within international acceptable standards. In fish tissues, however, Cr values were <0.003µg/g in both locations throughout the study period. At Abalama, Cd ranged between 7.18µg/g and 8.15µg/g, and Pb between 72.83µg/g and 92.23µg/g. At Ilelema, Cd concentrations were between 7.56µg/g and 8.67µg/g while Pb values ranged between 78.32µg/g and 92.88µg/g. Differences in heavy metal concentrations in both water and fish tissues between both locations were not statistically significant (p>0.05). All fish species and tissues bioaccumulated appreciable concentrations of the heavy metals. Cr in fish tissues was within permissible limits, but all Cd and Pb values exceeded international permissible limits.

The abbreviation for concentrations in micrograms per gram of dry weight should be corrected in two places. On page 120 "mg/g" left column line 18, and right column line 21, should be "μg/g".
