Topal, Murat; Topal, E.Işıl Arslan; Öbek, Erdal
The aim of the present study was to investigate the potential risk to human health from toxic/carcinogenic arsenic in ripe (RiTo) and unripe tomatoes (UnRiTo) grown in the municipal wastewater treatment plant effluents exposure zone. The arsenic concen-trations were determined in each tissue of RiTo and UnRiTo tomatoes. Arsenic values in tomatoes were root>leaf>unripe tomato>ripe tomato>stem. The maximum ED (exposure dose) value in RiTos was 1.21E-02 mg.kg-1.day-1 for child, minimum ED value was 4.80E-03 mg.kg-1.day-1 for male. The ED value was calculated as 5.44E-03 mg.kg-1.day-1 for female. The maximum ED value in UnRiTo was 2.12E-02 mg.kg-1.day-1 for child, min ED value was 8.39-03 mg.kg-1.day-1 for male. ED value was calculated as 9.51E-03 mg.kg-1.day-1 for female. EDs in RiTo and UnRiTo were child>female>male. When the HQs (hazard quotient) in RiTo and UnRiTo compared, HQ values in UnRiTo were higher. All of the HQ values were higher than 1. As a re-sult, results of tomatoes analysis show that there was non-carcinogenic and carcino-genic health risks.

Topal, Murat; Topal, E.Işıl Arslan; Aslan, Ali; Öbek, Erdal
Investigation of various species of lichen as biomonitors of air pollutants deposition and evaluation of element pollution were aimed. Maximum accumulation was 43.9±2.1 mg/kg in X. somloensis. Strontium in lichen species was quite high. Percentages of strontium for L.pulmonaria, C.furcata, U.longissima, X.somloensis, and F.caperata were between 58% and 78% indicating the efficient accumulation of strontium. Lichens were also accumulated strategically important elements. Maximum contamination factors in lichens were for strontium and tantalum. Maximum contamination factors of hafnium, niobium, lithium, gallium, and bismuth were for L. pulmonaria while maximum contamination factors of strontium, yttrium, scandium, and cerium were for X.somloensis. Maximum contamination factor of tantalum was for F.caperata. Enrichment factors for L.pulmonaria, C.furcata, and F.caperata were higher than 10, only for bismuth while lower than 10 for U.longissima. Enrichment factors for X.somloensis were higher than 10. Pollution load indexes for L.pulmonaria and U.longissima were higher than 1. Presence of strategically important elements in lichens showed that lichen species can be used as biomonitors of air pollutants.

Topal, Murat; Topal, E.Işıl Arslan; Öbek, Erdal
Accumulation and health risk assessment of cobalt (Co), antimony (Sb), vanadium (V), and lanthanum (La) in tomatoes growing in an area contaminated with municipal wastewater were investigated. For this aim, tomatoe samples were taken and sepertaed into root, stem and leaf parts. Co, Sb, V and La concentrations were detected in plant organs. The arrangement of the elements in the root, stem, and leaf of ripe and unripe tomatoes was V>Co>La>Sb. According to total element values in the ripe and unripe tomatoes; the highest values were 23±1.1 mg/kg and 35±1.7 mg/kg for V, respectively. Co, Sb, V, and La values accumulated by ripe and unripe tomatoes were determined as 24.65 and 25.6 times for Co, 1.8 and 2.7 times for Sb, 46 and 70 times for V and 4.4 and 6.15 times for La, respectively when compared with control. Total Co, Sb, V, and La were male

Topal, Murat; Topal, E.Işıl Arslan; Aslan, Ali; Öbek, Erdal
Some trace elements in various lichens as biomonitors of pollution were investigated. Also, the pollution status was assessed by enrichment factor, contamination factor, and pollution load index. Investigated elements were Ta, Bi, Hf, Nb, Ga, Sc, Li, Y, Ce, and Sr. The lichen species were Rhizoplaca chrysoleuca, Umbilicaria vellea, Aspicilia calcarea, Pseudevernia furfuracea, and Cetraria islandica. According to the results, lichen species accumulate Sr element well. The highest trace element accumulated by Pseudevernia furfuracea (21.7±1.0 mg/kg; 75%), Rhizoplaca chrysoleuca (31.9±1.6 mg/kg; 61%), Umbilicaria vellea (16.3±0.8 mg/kg; 59%), Aspicilia calcarea (77.9±3.8 mg/kg; 88%), and Cetraria islandica (22.7±1.1 mg/kg; 75%) was determined as Sr. The highest CFs in lichens investigated were calculated for Sr, Ta, and Li. PLI values for Cetraria islandica, Aspicilia calcarea, and Umbilicaria vellea were greater than 1. As a result, it has been proven that these lichen species can be used as good biomonitors of pollution.

Topal, Murat; Topal, E.Işıl Arslan; Öbek, Erdal
Aim of our study was the determination and monitoring of tetracycline (TC) and degradation products (DEP) in livestock slaughterhouse wastewater treatment plant (SWWTP) effluent. For this purpose, TC and DEP values in SWWTP were investigated. The concentrations of TC and DEP were monitored for 12 months. TC, 4-epitetracycline (ETC), 4-epianhydrotetracycline (EATC), anhydrotetracycline (ATC), and physicochemical parameters of pH, suspended solids (SS), BOD5, COD, and TP were calculated. The maximum TC concentration was determined as 1.68±0.08 µg/L in March and the minimum TC was 1.08±0.05 µg/L in January. The maximum ETC was 2.93±0.14 µg/L in March and April. The minimum ETC was 1.98±0.1 µg/L in January. EATC was 10.82±0.5 µg/L in September, and minimum EATC value was determined as 9.14±0.4 µg/L in March. The maximum ATC value was 8.62±0.4 µg/L in June and the lowest ATC value was 6.61±0.3 µg/L in September. Concentrations of TC and DEP detected in SWWTP effluent were listed in descending order as EATC> ATC> ETC> TC.

Topal, Murat; Topal, E.Işıl Arslan; Toraman, Zülal Aşçı; Süer, Ceren Sel; Öbek, Erdal
Bu çalışmada, Elazığ'da (Türkiye) bir kentsel atıksu arıtma tesisinde (AAT) SARS-CoV-2 ve gastrointestinal patojenler araştırılmıştır. Gastrointestinal patojen analizleri AAT giriş ve çıkış sularında, SARS-CoV-2 analizleri ise arıtma tesisinin farklı ünitelerinde yapılmıştır. Elde edilen analiz sonuçlarına göre AAT’nin girişinde gastrointestinal patojenler (bakteriyel, viral, EPA ve dışkı parazitleri) tespit edilmiştir. AAT'nin atıksularında enterohemorragik / verotoksin üreten Esherichia coli, gastroenterite neden olan tüm viral ajanlar (sapovirüsler (Sapo) hariç), insan parekovirüs (HPeV) ve EPA'dan adenovirüsler ve dışkı parazitlerinden Giardia lamblia tespit edilmiştir. AAT çıkışında gastroenterite neden olan bakteriyel ajanlar, viral ajanlar, EPA ve dışkı parazitleri incelendiğinde 7'de sadece 1, 6'da 4, 3'te 2 ve 3'te 1 ajan pozitif (+) olarak tespit edilmiştir. Atık su arıtma tesisinin her bir ünitesinden alınan numunelerde SARS-CoV-2 tespit edilememiştir. Sonuç olarak, araştırma bulgularına göre, atık su arıtma tesisi atık sularında patojenlerle karşılaşıldığından, çevre ve insan sağlığını korumak için arıtma tesislerinde dezenfeksiyon sistemine sahip olmak ve patojenleri ve SARS-CoV-2'yi sürekli izlemek gerekmektedir.
