  Some nanotoxicity effects of copper (60-80 nm) and copper oxide (40 nm) nanoparticles on Artemia salina

  Cimen, Isıl Canan Cicek; Danabas, Durali; Ates, Mehmet

  In this study, nanotoxicity tests were made by exposure of Artemia salina to copper (Cu 60-80 nm) and copper oxide (CuO 40 nm) nanoparticles (NPs) at different concentrations (0.2, 1, 5, 10, 25, and 50 mg/L). The LC50 value of Cu (60-80 nm) NPs on the A. salina individuals at the beginning (0), 24th, 48th and 72nd hours and elimination period was 52.37 mg/L while the LC50 value of CuO (40 nm) NPs was 55.39 mg/L. The results of UV-Vis absorbance values showed that all statistical data revealed that maximum effect was observed between 24-30 hours and 25 ppm absorbance concentration was more effective. The multiple R, correlation coefficient (R2) and adjusted R2 values of Cu NP for the suitable Quadratic model were, respectively; 92.96 %, 86.42 % and 76.71 % while they are 98.31 %, 96.64 % and 94.25 % for CuO NP. Also, the data, was indicated effect size significantly changed based on the type and size of NP. Considering the microscope results, it was clearly noticed that A. salina organisms took the NPs in to their body. The accumulation in the gut of A. salina was observed and the images were taken with phase contrast microscope for both of NPs. The highest decrease for survival rates of A. salina individuals exposed to Cu NP was observed in the 10 ppm concentration (43.47 %) and in the 5 ppm concentration (46.20 %) for CuO NP. The results revealed that Cu and CuO NPS showed different toxic effects and that Cu NPs were more toxic than CuO.

  Chatha, Ahmad Manan Mustafa; Naz, Saima; Danabas, Durali

  The demand for sustainable and efficient protein sources in aquaculture has led to an increasing interest in exploring alternative feeds for fish. In recent years, insects have emerged as a promising option due to their nutritional value, economic viability, and potential to alleviate the environmental impact of traditional fish meals. This review critically examines the existing literature on the effect of insect feed on fish growth. Through a comprehensive analysis of relevant studies, we evaluate the performance of fish fed with insect-based diets compared to those fed with conventional feeds. The review encompasses various insect species, feed formulations, and fish species, providing insights into the factors influencing growth outcomes. Our findings highlight the potential benefits and challenges of incorporating insect-based feeds in fish farming practices, with implications for sustainable aquaculture and food security. By synthesizing current knowledge, this review aims to guide future research and decision-making processes for optimizing fish nutrition and production while promoting ecological sustainability.

  Gholizadeh, Mohammad; Bagheri, Tahereh; Harsij, Mohammad; Danabas, Durali; Zakeri, Mohammad; Siddique, Mohammad Abdul Momin

  This study examined the occurrence of microplastics (MPs) in the gastrointestinal tract (GIT) of 384 fishes classified into four species from 11 sites in 2022 from the southern part of the Caspian Sea. GITs of fishes were collected and digested in H2O2 and KOH at 45 °C for 72 h. After filtration, extracted MPs were observed under a stereomicroscope, and selected MP particles were identified using FTIR. Presence of MPs was 68.98% in the GIT of the investigated fish. The mean abundance of MPs was 5.9 ± 0.9 MPs/GIT in Rutilus kutum, 9.2 ± 1.2 MPs/GIT in Chelon auratus, 3.6 ± 0.7 MPs/GIT in Alosa braschnikowi, and 2.7 ± 0.5 MPs/GIT in Vimba vimba. The predominant form of MPs was fiber (58.21%), followed by fragment (34.77%). Black (34.4%), white (19.07%), and blue (14.58%) were the most frequently detected colors of MPs. Overall, 6 MP polymers were identified, dominantly polypropylene (42.86%), polystyrene (17.86%), and cellophane (14.28%). The western part of the Caspian Sea (mostly tourist spots and urban areas) showed more MP pollution in fish compared to the eastern part. Polymer hazard index (PHI) revealed alarming microplastic contamination in the southern Caspian Sea. The PHI value of the present study showed that PES (PHI = 8403.78) and PS (PHI = 535.80) were “Extreme danger” and “Danger” risk categories, respectively.

  Naz, Saima; Chatha, Ahmad Manan Mustafa; Khan, Nisar Ahmed; Ullah, Qudrat; Zaman, Faisal; Qadeer, Abdul; Khan, Ibrar Muhammad; Danabas, Durali; Kiran, Azka; Skalickova, Sylvie

  Plastic pollution ranks among the most severe environmental disasters caused by humans, generating millions of tonnes of waste annually. The extensive and unregulated use of plastics has led to ecotoxicity and environmental imbalance. Microplastics (MPs) are prevalent in aquatic environments, and these MPs further degrade into even smaller particles known as nano-plastics (NPs). Both MPs and NPs impact the environment by readily absorbing organic pollutants and pathogens from their surroundings, owing to their bigger surface area to volume ratio. This review focuses on the source of origin, bioaccumulation, and potential impact of MPs and NPs on aquatic organisms and human health. Additionally, the review explores various methods employed for identification and quantification of these particles in aquatic ecosystems. Sufficient information is available on their characteristics, distributions, and effects on marine ecosystems compared with freshwater ecosystems. For plastic particles <10 μm, more toxicological effects were observed compared with larger size particles, in aquatic life. Understanding the mechanism of action and ecotoxicological effects of micro/nano-plastics on the health of aquatic life across various trophic levels, as well as human health, is of utmost importance. We address knowledge gaps and provide insights into future research approaches for a better understanding of the interactive mechanisms between binary pollutants.

  Effects of Cadmium and Nickel on Embryonic Development of Fish: A Review

  Danabaş, Durali; Naz, Saima; Chatha, Ahmad Manan Mustafa

  In fish embryos, a variety of abnormalities have been found, including stunted growth, a reduced survival rate, and aberrant development. One plausible explanation is that early embryonic stages are more sensitive. Embryonic studies provide additional information regarding the various impacts of heavy metals on fish, but information on larval abnormalities caused by waterborne metals is lacking. It is found that cadmium (Cd) causes a decrease in thyroid hormone levels as well as a disruption in fish growth hormone expression. Similarly, negative health effects have been documented as a result of nickel (Ni) exposure. Some toxic effects on organs, skin irritation, skin itches or blisters and allergic reactions may occur as a result of Ni exposure. This review study focuses on the impacts of Cd and Ni, on the embryonic development of different fish species. The evidence on abnormalities in fish larvae caused by Cd and Ni was also provided in text.

  Bioaccumulation Pattern and Health Risk Assessment of Heavy Metals in Cirrhinus mrigala at Panjnad Headworks, Bahawalpur, Pakistan

  Naz, Saima; Chatha, Ahmad Manan Mustafa; Danabas, Durali; Khan, Muhammad Farhan; Xu, Youhou; Zhu, Peng; Shafique, Laiba

  Heavy metal accumulation in freshwater ecosystem has become one of the major aquatic environmental concerns for freshwater flora and fauna due to their higher stability and bioaccumulation as well as bio-magnification properties. Furthermore, passing through the food web, these heavy metals affect human populations ultimately. This study assessed the heavy metal accumulation in Cirrhinus mrigala in spring, autumn, and winter at different locations (I, II, and III) of Panjnad headwork. Furthermore, the human health risk assessment for the consumption of C. mrigala from the sampling locations was also carried out. Fish were collected from upper (I), middle (II), and lower (III) stream of Panjnad on a monthly basis. The current study evaluated the accumulation of Aluminum (Al), Arsenic (As), Barium (Ba), and Lead (Pb) in various fish organs (liver, kidney, gills, fins, skin, muscles and bones) and assessed their potential hazard to human health through health risk assessment indicators. The results demonstrated a significant difference (p < 0.05) in heavy metal accumulation in different fish organs, seasons, and locations. The accumulation of Al, As, Ba, and Pb were considerably higher in liver and kidney as compared to the other body organs and followed a trend of liver > kidney > gills > fins > skin > bones > muscle and the overall mean concentrations of metals in different body tissues of C. mrigala were in the order of Al > As > Ba > Pb. The results also concluded that C. mrigala caught from the Panjnad headwork is not safe for human consumption due to higher values of TTHQIng (3.76), THQIng for Ba (3.27) and CRIng for As (6.4742).

  Age- and Sex-Specific Bioaccumulation of Selected Metals in Freshwater Mussel (Unio elangatulus eucirrus Bourguignat, 1860) Populating from Keban Dam Lake (Elazig, Turkey)

  Danabaş, Durali; Kutluyer, Filiz; Ural, Mesut; Özçelik, Mehtap; Kocabaş, Mehmet

  In aquatic life, environmental chemicals are accumulated by mussels due to their sentinel nature and filter-feeding characteristics. Herein, the present study focused on assessing the concentrations of Cu, Zn, Mg, Mn, Fe, Cd, Pb, Ca, K, and Na levels in freshwater mussels (Unio elangatulus eucirrus) depending on sex and age. For all trace metals, some important differences of bioaccumulations were determined depending on ages and sex. In details, the results indicated that an important age-related accumulation of Mg, Cd, Ca, and K was in females and all trace elements, except Cu, Mg, and K levels in males (p < 0.05). No statistical differences were determined in mean concentrations of Cu, Zn, Mg, and Na. There are statistical differences in Mg, Mn, Fe, and Ca levels between females and males in four aged mussels (p < 0.05). Lead levels were under detectable limits. Overall, metal levels and their toxicity in freshwater mussels should be closely monitored for health of the environment, animals, and humans, since mussels and fish species fed on them are consumed highly in the research region and around.

  Potential Role of Zeolite on Improvement of Aquaculture Sector

  Danabaş, Durali; Dörücü, Mustafa

  Aquaculture, which is very important in many regions of the world, attracts attention as the fastest\rgrowing sector in the livestock sector in our country. The share of our country's aquaculture\rproduction in the production of total aquatic products is increasing day by day. Studies have been\rcarried out to solve feed problems and importance has been attached to additives that reduce cost\rand feed conversion ratio (FCR) to contribute to feed quality. Zeolites came to the forefront as feed\radditives. Due to the gap between 20 and 50 % in the structure, the molecules can be taken into the\rstructures and they are named as molecular sieves. Zeolites are used for purposes such as controlling\rthe pollution in pools in the aquaculture sector, increasing the growth parameters of the fish by\rincubation, fish transport and removal of nitrogen compounds from aquarium water, increasing\rambient oxygen in aquarium and fish transport, and as feed additive. In Turkey, billions of tons of\rzeolite have been detected and clinoptilolite type zeolite is found mostly in the beds of AnkaraPolatlı-Mülk-Oğlakçı Region and Bigadiç, Şaphane, Gediz, Emet and Gördes Districts. We believe\rthat the use of zeolites produced in Turkey as a local and natural product as feed additive substance\rin the aquaculture industry in the aquaculture sector will contribute to the production of lower cost\rfish as well as contribute to the development of 2 different sectors (aquaculture and mining) in\rinteraction with each other.

  Assessment of impact of α-Fe2O3 and γ-Fe2O3 nanoparticles on phytoplankton species Selenastrum capricornutum and Nannochloropsis oculata

  Ates, Mehmet; Cimen, Isil C. C.; Unal, Ilkay; Kutlu, Banu; Ertit Tastan, Burcu; Danabas, Durali; Aksu, Onder; Arslan, Zikri

  In this study, the impact of alpha-iron oxide (α-Fe2O3, 20-40 nm) and gamma iron oxide (γ-Fe2O3, 20-40 nm) nanoparticles (NPs) on phytoplankton species Selenastrum capricornutum and Nannochloropsis oculata was investigated Characterizations of the NPs were systematically carried out by TEM, dynamic light scattering, zeta potential, X-ray diffraction, SEM, and Fourier transformation infrared spectroscopy. Acute toxicity was tested between 0.2 and 50 mg/L for each NP for a period of 72 hours exposure. γ-Fe2O3 NP inhibited development of N oculata at the rate of 54% in 0.2 mg/L group with a high mortality rate of up to 82%. α-Fe2O3 NPs were less toxic that induced 97% mortality on N oculata at 10 mg/L suspensions. In contrast, α-Fe2O3 NP inhibited growth of S capricornutum strongly (73%) in 0.2 mg/L group. γ-Fe2O3 NPs showed similar growth inhibition (72%) on S capricornutum in 10 mg/L suspensions. Despite the differential effects, the results indicated acute toxicity of α-Fe2O3 and γ-Fe2O3 NPs on N oculata and S capricornutum.
