    Assessment of Toxic, Essential, and Other Metal Levels by ICP-MS in Lake Eymir and Mogan in Ankara, Turkey: An Environmental Application
    (Atomic Spectroscopy Press Ltd, 2018) Yuksel, Bayram; Arica, Enes
    The goal of this study was to develop and validate a sensitive ICP-MS method for the determination of some toxic metals (Al, As, fig, Pb, Cd. Ni. Cr, and Sb), along with essential and other elements (Fe, Cu, Zn, Mn, Se, Co, and Ti) in water samples collected from 20 sites of Lake Eymir and lake Mogan in Ankara, Turkey. The mean metal concentrations, except for As, in the water samples of the two lakes were found at safe levels. The As levels in Lake Mogan (12.15 +/- 0.41 mu g/L) and Lake Eymir (11.49 +/- 0.66 mu g/L) were higher than the permissible limits recommended for drinking water of 10.0 mu g L-1 As. The significance of this paper fundamentally addresses the assessment of general signal optimization for multi-element analysis and reducing interferences during validation and optimization of this ICP-MS method. Good linearity with a correlation coefficient between 0.9911 and 1.000 was obtained, respectively. Imprecision was measured as the coefficient of variation (CV), which ranged between 1.16% and 4.79%. Recovery of the method was between 97.3% and 103.6% for all elements, which supports the accuracy of the method. The procedure described is relatively simple, precise, and applicable for mutine environmental metals analysis in natural water samples.

    Evaluation of Heavy Metal (Lead, Mercury, Cadmium, and Manganese) Levels in Blood, Plasma, and Urine of Adolescents With Aggressive Behavior
    (Cureus Inc, 2023) Yildiz, Suleyman; Pirinccioglu, Ayfer Gozu; Arica, Enes
    Background Heavy metals can cause health problems by affecting the biological structure even at very low concentrations. Asymptomatic heavy metal poisoning causes non-specific symptoms such as behavioral disorders, difficulty in learning, and aggressive behaviors. There is also a great concern about the incidence of aggressive behavior among adolescents. A few research studies have concluded that a complex interaction or combination of factors leads to an increased risk of aggressive behavior in adolescents. This study aims to determine the correlation between the heavy metal levels in blood, plasma, and urine and the aggression level in adolescents. Materials and methods Two hundred twenty-eight adolescents between the ages of 13 and 19 were enrolled in the study. Blood, plasma, and urine heavy metal levels of the participants were measured by an inductively coupled plasma mass spectrometer (ICP-MS) device (Model 7700x; Agilent, Santa Clara, CA, USA). Buss and Perry's aggression questionnaire was used to investigate the correlation between heavy metals and aggressive behaviors in adolescents. Results Lead blood (r=0.34, p<.01), lead plasma (r=0.22, p<0.01), lead urine (r=0.31, p<.01), mercury blood (r=0.35, p<0.01), mercury urine (r=0.21, p<0.01), manganese blood (r=0.34, p<0.01), manganese plasma (r=0.33, p<0.01) and manganese urine (r=0.39, p<0.01) were positively correlated with tendency to aggression whereas no significant relationship was found between cadmium in blood, plasma, urine and mercury in plasma with aggression. Conclusion The study showed valuable data to associate a significant relationship between adolescents' aggression levels and heavy metals. There is an undeniable relationship between the health of adolescents and environmental pollution caused by heavy metals. Therefore, taking the necessary measures to prevent environmental heavy metal pollution is crucial for adolescent health.

    Evaluation of iodine and selenium level and thyroid functions in patients with cystic fibrosis
    (Walter De Gruyter Gmbh, 2025) Unal, Edip; Arica, Enes; Tas, Funda Feryal; Kolbasi, Baris; Beyazit, Nurcan; Kaplan, Ibrahim; Savas, Suat
    Objectives There is limited research on thyroid function in pediatric patients with cystic fibrosis (pwCF). This study aimed to determine the frequency of thyroid dysfunction in children and adolescents with CF and to evaluate iodine deficiency and selenium status in pwCF.Methods Sixty-two CF patients and 62 control subjects were evaluated. The anthropometric measurements, nutritional status, FEV1(Forced-expiratory-volume in 1 s) percentage, thyroid function tests (TSH, FT4, FT3), urinary iodine and selenium levels, hospitalization status in the last six months, antibiotic usage, and colonization status with staphylococcus or pseudomonas were assessed for the cases.Results The mean age of the patient group was 10.84 +/- 4.04 years. All CF patients were receiving multivitamin supplementation. Malnutrition was present in 50 % of patients, bacterial colonization in 29 %, FEV1 decrease in 38.5 %, subclinical hypothyroidism (SH) in 12.9 %, iodine deficiency in 87 % and exocrine pancreatic insufficiency in 100 %. T3 levels were found to be higher in pwCF. No significant difference was found between malnutrition and FEV1 and urinary iodine and selenium levels. Compared to the control group, pwCF had lower urinary iodine levels.Conclusions To the best of our knowledge, our study is one of the few in the literature to investigate urinary selenium levels alongside iodine in PwCF. Further research is needed to clarify and interpret elevated urinary selenium levels in this context. It was shown that iodine deficiency and the rate of SH were relatively high in pwCF. However, it was still thought that correcting iodine deficiency in these patients could improve thyroid dysfunction associated with CF.

    ICP-MS Determination of Lead Levels in Autopsy Liver Samples: An Application in Forensic Medicine
    (Atomic Spectroscopy Press Ltd, 2018) Arica, Enes; Yuksel, Bayram; Yener, Ismail; Dolak, Ibrahim; Gok, Ertugrul; Yilmaz, Eyup
    The objective of this study was to develop and validate a senstitive ICP-MS method with no gas mode for the determination of Pb levels in autospy liver samples collected from patients in Diyarbakir, Turkey. The microwave-assisted acid digestion procedure was optimized and applied to accurately weighed dry liver samples. The method showed linearity in the range of 0-100 mu g/kg with a detection and quantification limit of 0.72 mu g/kg and 2.18 mu g/kg, respectively. The calibration graph was characterized with excellent correlation coefficients (r=0.9997) for Pb determination. Certified reference material was used to validate the method in terms of accuracy, precision, and recovery. Good agreement was obtained between the certified values and the measured Pb concentrations. Percent recovery and precision for Pb was calculated at 99.5% and 4.29%, respectively. In the autopsy liver samples, the Pb levels ranged from 106.83 mu g/kg to 1932.08 mu g/kg and the mean Pb levels were found at 375.24 +/- 325.46 mu g/kg. As a result of the statistical analysis, the occupation, smoking habit, settlement, gender, and age appeared to have an effect on the Pb levels in the autopsy liver samples. The procedure described is relatively simple, precise, and applicable for routine toxicological Pb determination in human tissue.

    Impacts of a Garbage Disposal Facility on the Water Quality of Cavuslu Stream in Giresun, Turkey: A Health Risk Assessment Study by a Validated ICP-MS Assay
    (Istanbul Univ Press, Fac Aquatic Sciences, 2021) Yuksel, Bayram; Ustaoglu, Fikret; Arica, Enes
    Environmental concerns have been raised because of a garbage disposal facility (GDF) constructed near Cavuslu Stream in Giresun, Turkey. This article proposes a fully validated ICP-MS technique to investigate the impacts of the GDF on the water quality of the stream and provide a human health risk estimation. Water sampling was carried out at four different stations and in tap water since the stream is the primary source of drinking water for the inhabitants of the town. Quantification of selected toxic metals (As, Pb, Cd, Hg, Sb, Al, and Ni) in conjunction with the essential and other elements (Se, Cu, Fe, Mg, Mn, Zn, and Co) was performed by the use of the previously validated ICP-MS method. Once water quality index (WQI), heavy metal pollution index (HPI), and heavy metal evaluation index (HEI) were computed, the health risk assessment was studied according to the US EPA's method. Although the stations (2, 3, 4, and tap water) showed excellent water quality, station-1, which is the closest one to the facility, was classified as poor water quality. Lifetime cancer risk (LCR) was only significant both for adults and children in station-1. In addition, low risk regarding non-carcinogenic health hazards was found for children. The results indicate that the facility decreases the water quality of this stream and is possibly responsible for LCR. In conclusion, the ecological environment and human health should be protected by further monitoring the effect of the GDF on the ecological system.

    Serum mineral levels and haematobiochemical parameters in buffalo calves with allotriophagy (pica syndrome)
    (Polish Soc Veterinary Sciences Editorial Office, 2023) Kochan, Akin; Simsek, Aynur; Arica, Enes
    Pica is defined as a depraved or abnormal appetite characterized by licking and eating non-nutritive substances. The aim of this study was to report changes in the serum mineral levels and haematobiochemical parameters of buffalo calves with pica. The study included 30 buffalo calves exhibiting pica behaviour, such as licking stall walls or eating wool and non-food items (pica group), and 6 buffalo calves without the signs of pica behaviour (control group). The age of both groups ranged between 1 and 6 months. In the pica group, the haematological analysis revealed a decrease in red blood cells (P < 0.001) and red cell distribution width (P < 0.05) as well as an increase in the mean corpuscular volume and mean corpuscular haemoglobin (P < 0.001), whereas the biochemical parameters were characterized by an increase in aspartate aminotransferase (P < 0.01), alanine aminotransferase (P < 0.001) and lactate dehydrogenase (P < 0.05) levels and a decrease in creatinine and glucose (P < 0.01) levels. Furthermore, the pica group showed a significant decrease in serum manganese, iron, zinc, selenium (P < 0.001) and copper (P < 0.01) concentrations. In conclusion, it was determined that deficiencies in the levels of serum iron, copper, zinc, manganese and selenium play an important role in the aetiology of pica in buffalo calves.
