In this research, in order to observe the seasonal change between April 2014 and February 2015, heavy metal contents in the water, sediment and the Carassius gibelio (Bloch, 1782) tissues (muscle, gill and liver) growing in Eber Lake were determined. The obtained results showed that trace elements were founded in water, sediment and fish tissues. Among the average annual concentrations of water samples, the highest concentration was found for Mn (0.1584 mg/L) element and the lowest concentration was found for Pb element in the spring season. the maximum Average annual concentration was calculated for Mn (0.1584 mg/L, Spring) and the minimum was determined for Pb in water. In the sediment, Fe (16245.84 mg/kg, Spring) was found to be maximum and Co was the minimum. In fish, the highest concentrations were found in liver (Mo, Ni, Pb, Co, Cu, Fe), while the lowest concentrations were found in gill (Mn, Zn) and muscle (Cd, Cr, Se) tissues While the highest heavy metal concentrations were observed in the sediment, the minimum was found in the fish tissues (the ranking was the following; liver, gill and muscle). It was concluded that the heavy metal levels measured in the Lake Eber have no risk to the environment and to the public health.

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<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<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<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 physicochemical properties and the concentrations of heavy metals of water samples collected from four different rivers of Nkanu east and west Local Government Areas of Enugu of state Nigeria were investigated because of the prevalent water borne diseases in these localities attributable to the drinking of contaminated water. The water samples were collected from different sites of Esu, Umuekwe, Umuobeagu and Atafu rivers and their physicochemical properties and heavy metal contents were measured. Sampling Stations were selected; samples were collected avoiding contamination from the selected sites in same season, from same depth. On site measurement of parameters was done with the same instruments. Rests of the parameters were measured in Laboratory. Lead (Pb) was present in Esu, Umuekwe, Umuobeagu and Atafu rivers at a concentration of 0.14, 0.03, 0.00 and 0.16 mg/L respectively; Zn was only detected in Esu and Umuobeagu at 0.07 and 0.01 mg/L respectively and cadmium (Cd) concentrations of 0.14, 0.14. 0.08 and 0.08 mg/L respectively. Iron was detected in only Umuekwe river having 0.17 mg/L and Atafu river having 0.21 mg/L while Ni was detected at 3.01, 4.20, 1.20 and 3.83 mg/L respectively. Only Atafu river had Cr at 0.01 mg/L, only Esu river had Co content at 0.05 mg/L, Mn content in Esu, Umuekwe, and Umuobeagu was found to be 0.01, 0.02 and 0.02 mg/L respectively with Atafu river having none. Hg concentration was found to be 0.57, 0.06, 0.42 and 0.82 mg/L for Esu, Umuekwe, Umuobeagu and Atafu rivers respectively. The concentrations of Pb and Cd were higher in all the four samples especially in Esu river as a result of its closeness to construction sites and refuse dump and the concentrations were above the acceptable limits of WHO standard of 0.010 and 0.005 mg/L respectively for drinking water while Hg, Fe, and Ni were found within the W.H.O limits of 0.001, 3.000 and 0.100 mg/L respectively. The rest were below the standard, thus confirming conclusively that the rivers are polluted with the presence of heavy metals.

Abstract Collared flycatchers (Ficedula albicollis Temminck, 1815), have more opportunities to accumulate heavy metals due to migration but they are more resistant to contamination in contrast to tits, (Parus major Linnaeus, 1758, Parus caeruleus Linnaeus, 1758). This research aimed to detect concentrations of some trace elements in eggs of the collared flycatcher, great tit and blue tit in different areas. There were found differences in heavy metal concentrations in the eggs among species and study areas. For collared flycatchers there were not established consistent patterns of changes in element concentrations among areas. The highest heavy metal levels were found in tits in samples of egg contents from a forest park (Pb - 3.1410 ± 0.3249, Cu - 19.3290 ± 1.4840, Zn - 66.9612 ± 17.6665, Fe - 249.5513 ± 40.2800, Mn - 6.9032 ± 0.2946, Ca - 8298.3570 ± 0.1080, Sr - 17.6032 ± 0.7512, Ni - 0.5177 ± 0.0220). The lowest concentrations were found in egg contents of tits in Hetmanskyi National Nature Park (Cu - 4.3492 ± 0.2079, Fe - 44.6647 ± 0.2627, Mn - 1.3194 ± 0.2374, Ca - 998.7001 ± 0.0006, Ni - 0.2443 ± 0.0439, Cr - 0.1466 ± 0.0424). The results indicate that heavy metals accumulated differently in shells and contents of eggs of collared flycatchers and tits in each of the study area. Some of microelements (zinc, mercury, iron, manganese, selenium and iodine) in small amounts are required for normal growth and development of birds. Heavy metal concentrations in egg shells and egg contents of all species did not exceed permissible levels.

Abstract The aim of the study was to determine the levels of selected trace elements in soils and in the common dandelion depending on the distance from a traffic route. The study was conducted in Warsaw near one of the main roads in the suburb of Ursynów. Samples for testing were taken from the 0–25 cm layer at sites located directly alongside the roadway and at a distance of 30, 60 and 300 m from its edge. The amounts of Pb, Ni, Cu, Zn and Cd in the soils were determined by the AAS method, after extraction in HCl at a concentration of 1 mol·dm−3, and in the aboveground parts and roots of dandelion plants after wet mineralization in a mixture of HNO3 and HClO4 by the AAS method. On the basis of the results obtained, it was shown that the concentrations of the tested metals, both in the soils and in the biomass of the test plant, were highest directly at the edge of the roadway and decreased significantly with the distance away from the road. This correlation indicates a significant impact of road transport on heavy metal levels in the environment bordering a traffic route. It was also shown that dandelion plants accumulate higher amounts of heavy metals in the aboveground parts than in the roots, and the heavy metal contents in the dandelion biomass were found to be significantly positively correlated with the amounts of these elements in the soils.

Heavy metals are among the pollutants threatening the living organisms including human beings. The presence of heavy metals in water is of great concern due to their toxicity to aquatic organisms, humans and ability to accumulate in food chains. Thus, there is a need to regularly monitor heavy metal levels in aquatic medium. The present study was conducted to assess heavy metal concentrations in Lake Kivu water. Water samples from Lake Kivu were taken from three sites, namely: Rusizi, Karongi and Rubavu. Heavy metals in the samples were analyzed using Atomic Absorption spectro-photometer (SHIMADZU AAS-6800) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES).Copper, lead, cadmium, chromium, manganese, mercury and arsenic concentrations were determined. Copper ranged from 3.24 to 10.01 μg/l, lead varied from 8.81 to 37.44 μg/l, cadmium ranged from 5.01 to 14.01 μg/l,chromium was between 139.5 and 226.6 μg/l, manganese varied from 598.3 to 795.7 μg/l, mercury ranged from 0 to 0.047 μg/l, while arsenic was not detected in any of the analyzed water samples. Except for arsenic, all the other heavy metals exceeded the EPA (US Environment Protection Agency) maximum permissible limit for class III surface water intended for fish consumption and recreation. Thus, there is a need to establish the sources of lake water pollution by heavy metals in order to design further strategies limiting the amounts of heavy metals entering Lake Kivu.

Abstract Background Heavy metal accumulation in the ecosystem constitutes a potential toxic effect which is hazardous to human health. Increasing environmental pollution has necessitated the use of cattle egrets to evaluate the levels of heavy metal contamination, to establish their use in biomonitoring of heavy metals and to provide data for monitoring pollution in the environment. Results The present study assessed the utilization of Bubulcus ibis in monitoring pollution in five abattoirs, namely Agege, Bariga, Kara, Itire and Idi-Araba, all situated in Lagos State. The concentration of five (5) heavy metals, cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) was determined in the liver, muscle and feather of Bubulcus ibis using the atomic absorption spectrophotometer. The trend of metal accumulation was in the order: Zn > Cu > Pb > Cd > Ni for all the sampled tissues. The mean tissue concentrations of the metals were significantly different (p < 0.05) among the sites. The highest levels of metal concentration were reported in the liver in all the locations. Mean concentration of Cd in Kara (0.003 ± 0.00058) was significantly (p < 0.05) higher than those found at Agege (0.0013 ± 0.00058) and Idi-Araba (0.001 ± 0.001). A significant difference (p < 0.05) was also observed between the mean concentrations of Cu in Bariga (0.01 ± 0.001) and Idi-Araba (0.003 ± 0.001). Conclusion All the studied heavy metals were present in the liver, muscle and feathers of the cattle egrets. The contamination levels were ascertained from the study which indicated that cattle egrets are useful in biomonitoring studies and the generated data will serve as baseline data which could be compared with data from other locations for monitoring heavy metal pollution.

The Impact

The aim of this study was to determine the effect of roasting on the contents of polyphenols (PPH), acrylamide (AA), and caffeine (CAF) and to analyze heavy metals in specialty coffee beans from Colombia (COL) and Nicaragua (NIC). Samples of NIC were naturally processed and COL was fermented anaerobically. Green beans from COL (COL-GR) and NIC (NIC-GR) were roasted at two levels, light roasting (COL-LIGHT and NIC-LIGHT) and darker roasting (COL-DARK and NIC-DARK), at final temperatures of 210 °C (10 min) and 215 °C (12 min), respectively. Quantitative analyses of PPH identified caffeoylquinic acids (CQA), feruloylquinic acids, and dicaffeoylquinic acids. Isomer 5-CQA was present at the highest levels and reached 60.8 and 57.7% in COL-GR and NIC-GR, 23.4 and 29.3% in COL-LIGHT and NIC-LIGHT, and 18 and 24.2% in COL-DARK and NIC-DARK, respectively, of the total PPH. The total PPH contents were highest in COL-GR (59.76 mg/g dry matter, DM). Roasting affected the contents of PPH, CAF, and AA (p < 0.001, p < 0.011 and p < 0.001, respectively). Nickel and cadmium contents were significantly higher in the COL-GR than in the NIC-GR beans. Darker roasting decreased AA content, but light roasting maintained similar amounts of CAF and total PPH.
