Pala, Ayşegül; Eroğlu, Mücahit; Mişe Yonar, Serpil; İspir, Ünal; Yonar, Muhammet Enis
This study examined the adverse effects of sublethal concentrations of cadmium (Cd) and the potential of curcumin (CUR) to mitigate Cd-induced toxicity. We administered 1.5 and 3 mg/L of Cd and 100 mg/kg of CUR to fish (Cyprinus carpio) separately and in combination over 14 days. At the end of the experiments, various haematological and immunological parameters, oxidative stress levels and antioxidant parameters of fish were measured, and the differences between the groups were evaluated. Simultaneous CUR treatment with Cd reversed the changes in haematological parameters in fish, increased immune responses, reduced oxidative stress and normalized the impaired antioxidant enzyme activities. In summary, our study showed that dietary supplementation with CUR may be an effective strategy to reduce the toxic effects of Cd in carp.

Arslan Topal, E. Işil; Topal, Murat; Çelik, Erdal; Öbek, Erdal
In this study, estimation of pollution and assessment of health risks related to the agricultural application of mussel shell–derived chitosan as organic amendment were evaluated. Furthermore, considering WHO maximum permissible levels in soil, the application rates of chitosan to agricultural soils were calculated. Geo-accumulation index (Igeo), enrichment factor (EF), contamination factor (CF), pollution load index (PLI), and ecological risk index (ERI) were calculated. Mussel shell-derived chitosan generally did not contribute to soil metal loading when evaluated in terms of those indices. The highest hazard quotient for ingestion (HQing) across male (ML), female (FML), and children (CL) followed the order Cr > Ni > Mn >Pb >Zn >Cu, while maximum HQing among metals was observed in the order CL > FML > ML. For inhalation exposure, highest HQinh for all metals was also found in the order CL > FML > ML, with individual metal contributions following Mn > Ni > Cr >Zn >Pb >Cu. Maximum HQder exhibited the trend ML > FML > CL, and the metal-specific order for HQder was Cr > Pb > Ni >Zn >Mn >Cu. Hazard Index (HI) and Total HI for ingestion, inhalation and dermal exposure were all less than 1. Cancer risk was less than 1 × 10−6. Consequently, there were no pollution and health risks associated with the use of musselshell‑derived chitosan in agriculture as organic amendment.

Kutluyer Kocabaş, Filiz; Başaran, Ertuğrul; Kocabaş, Mehmet
In aquatic ecosystem, metal pollution is an important environmental hazard. Mussels as a bioindicator species are often used for assessment the presence of potentially toxic metals. Hence, the present study aimed to assess the effect of seasonal variations on some heavy metals (Cd, Cr, Pb, As, Zn and Cu) accumulation in water and Dreissena polymorpha from lake habitat. Our result indicated that Zn accumulated at a very high level in the zebra mussels while As accumulated at a high level in water samples. Seasonal variations significantly affected Cu concentration in the water samples (P < 0.05) while Cr concentration in the mussel samples was significantly affected by seasonal variations (P < 0.05). According to the water analysis, mean concentrations of metals are below the maximum limits established by the World Health Organization and USEPA, except As. Overall, our data emphasize anthropogenic pollution in the Turkish aquatic environment and confirm the use of D. polymorpha as a prospective biomonitor for metal polluted sites’.

Kutlu, Banu; Dorucu, Mustafa
We determined the toxic effects of seven metals. copper (Cu), manganese (Mn). zinc (Zn), cobalt (Co). molybdate (Mo), lead (Pb), and cadmium (Cd) on the microalgae Tefraselmis chuii (Butcher, 1959). We exposed 50 mL of cultivated microalgae (f/2 Gaillard) in the exponential growth phase. with three replicates, to concentrations of 0 (control). 0.1, 1.0, 5.0, 10, 25. and 50 g L of each metal for 72 hours. The cellular count was recorded daily to evaluate any potential lethal effects. An increase in cellular density was seen in the control treatment. All treatments exposed to metals showed a logarithmic increase in cell density within 48 hours, with a cellular decrease that became evident later on. This study result with an insignificant decrease at low concentrations of Cd, Pb, and Cu at 24 hour was probably attributed to their use as micronutrients at these low concentrations. The most lethal effect was observed with Cd treatment, which killed 50% of the microalgae population at a concentration of 0.62 mu g L-1. In this study, this concentration was three times lower than that of lead and mercury. while being ten times lower than that of cobalt and molybdate. To elucidate the adverse effects on seawater environments, the microalgae Tetraselmis chuii is recommended as a model species.

Ustaoğlu, Fikret; Kutlu, Banu; Tepe, Yalçın; Aydin, Handan
The aim of this study is to detect the heavy metal contamination in the sediment of Batlama Stream and to evaluate the anthropogenic effect. Field studies were seasonally carried out in 3 stations between June 2014 and July 2015. In the sampling studies carried out in Batlama Stream, contamination factor (CF), enrichment factor (EF), potential ecological risk factor (Eri), lowest effect level (LEL), geoaccumulation index (Igeo) contamination indicators were used in order to evaluate sediment contamination. In Batlama Stream, average heavy metal level of three stations was detected in mg/dry kg in the sediment as Cr 7.08, Mn 63.62, Fe 858.04, Co 5.47, Ni 4.99, Cu 20.61, Zn 49.60, Cd 0.09, and Pb 20.68. Elements which the sediment has most are Fe, Mn, and Zn. According to EF, Pb was detected as an enriching element. Eri Pb is in the low risk group. In LEL value, the highest Pb average was found as 31. According to Igeo values, Pb is a moderate contaminant. This metal has anthropogenic sources and it is caused by domestic, agricultural, and waste waters. In the elements analysed in Batlama Stream sediment (apart from Pb), it is indicated that it is generally a clean stream and considered reference stream.

The objective of this study was to determine the heavy-metal concentrations (Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, and Hg), evaluate the pollution levels, and determine the concentration of chlorophyll-a and organic carbon in the surface sediments of the Uzunçayır Dam Lake, Tunceli, Turkey, between 2015 and 2016. In order to evaluate the effect of the pollution level in the study area, the contamination factor (CF), enrichment factor, potential ecological risk index, and pollution load index were used. The concentrations of the studied heavy metals were ordered as follows: Fe > Mn > Ni > Cr > Zn > Cu > Pb > As > Cd > Hg. The highest CF value was found for the Ni element among the studied heavy metals in the Dam Lake. Moreover, the highest CF mean value was found for the As contamination level. According to the toxicity analyses in the study area, the potential toxic effect of sediments was not at a very serious level.

In this paper, the heavy metal levels (Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, Hg), organic carbon, and chlorophyll degradation products were studied to prove their ecological effects in Lake CA +/- ldA +/- r, where fossil fuels are used as an energy source in the studied area for most of the year, and domestic waste from settlements is discharged directly into the lake. Sediment samples were collected from six sites on the northern shore of CA +/- ldA +/- r Lake, Turkey in November 2012. Enrichment (EF) and contamination factor (CF) values were determined, and Pollution Load (PLI) and Potential Ecological Risk (PER) indices were calculated. Average concentrations of heavy metals in the sediments were, in descending order, Fe > Mn > Zn > Ni > Cr > Cu > Pb > As > Cd > Hg, respectively. According to mean values, the source of these elements may be considered natural due to lack of enrichment in Cu, Pb, Zn, Ni, and Cr in the sediment samples. Regarding enrichment of As, Cd, Mn, and Hg, the highest EF belongs to Hg. PLI and PER values indicate there are moderate ecological risk in the lake.

Danabas, Durali; Ural, Mesut
The aim of this study was to evaluate Copper (Cu), Zinc (Zn), Selenium (Se), Chromium (Cr) and Cadmium (Cd) concentrations in liver, muscle, gills and kidney tissues of Capoeta trutta collected from four sites of Keban Dam Lake, Turkey. The highest heavy metal level in all tissues was for Zn, while Cd was the lowest. The lowest heavy metal levels were generally found at Station 4 (Agin) for all tissues (p < 0.05). There were statistically significant differences among stations for Cu, Zn, Cr and Se in gills; for Cu, Zn, Se and Cr in liver and kidney; and Cu, Zn and Cr in muscle (p < 0.05). Cadmium concentrations did not differ between sites for any of the tissues. Turkish Food Codex sets the maximum limits of Zn, Cu and Cd as, 50, 20 and 0.05 mg kg(-1) dry weight, respectively, in the muscle of fish used for human consumption. In our study, the level of Zn was higher than Turkish permissible limits only at Station 3 (Guluskur). Cadmium levels were much higher than permissible limits at three stations [S1 (Pertek), S2 (Kockale) and S3], whereas Cu levels were within permissible limits in all stations.
