  Pollution estimation and health risks assessment related to the agricultural application of mussel shell-derived chitosan as organic amendment

  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.

  Is Cladophora fracta an efficient tool of accumulating critical raw materials from wastewater and there a potential health risk of use of algae as organic fertilizer?

  Arslan Topal, E. Işıl; Öbek, Erdal; Topal, Murat

  In this study investigation of accumulations of critical raw materials (cobalt (Co), antimony (Sb), vanadium (V), lanthanum (La) and tungsten (W)) from wastewater by using C. fracta were aimed. Besides, assessment of the potential health risks in terms of the use of organic fertilizer obtained from the macroalga to be harvested from the treatment were also aimed. Highest Co, Sb, V, La and W accumulations by algae in reactor were 125±6.2%, 201.25±10%, 318.18±15%, 357.97±18%, and 500±25%, respectively. When compared with control, Co, Sb, V, La and W in algae increased 2.25, 3.01, 4.18, 4.58, and 6 times, respectively. The algae was very high bioaccumulative for Co and La. Highest MPI was calculated as 3.94. Non-carcinogenic risk of CRMs according to different exposure types (ingestion, inhalation, and dermal) were calculated for man, woman and child. There is not any non-carcinogenic risk from the investigated exposure ways of algae as organic fertilizer.

  Assessment of heavy metal accumulations and health risk potentials in tomatoes grown in the discharge area of a municipal wastewater treatment plant

  Arslan Topal, E. Işıl; Topal, Murat; Öbek, Erdal

  Some heavy metals were detected in organs of the tomatoes grown in the discharge area of effluents of a municipal wastewater treatment plant. Also, the health risk potentials of heavy metals in the tomatoes consumed by human were investigated. The highest concentrations for Cu, Ni, Cr, Mn and Pb were followed the order of root>leaf>stem>fruit. When the bioconcentration factors values calculated for bioconcentration of metals from effluent to stem and root were examined, the highest values were determined for Cu. When translocation factors values are examined, the highest translocation from root to leaf was determined for Cd. The highest translocation from stem to leaf was determined for Pb. The estimated total exposure dose for male, female and children was listed as Zn>Mn>Cu>Cr>Ni>Pb>Cd. In terms of dietary, we can list the non-carcinogenic risks of heavy metals as children> female> male. The highest carcinogenic risk was calculated for Cr via dietary intake.

  Potential human health risks of toxic/harmful elements by consumption of Pseudevernia furfuracea

  Topal, Murat; Arslan Topal, E. Işıl; Öbek, Erdal; Aslan, Ali

  The potential human health risks of some toxic/harmful elements related to the consumption of Pseudevernia furfuracea (L.) Zopf. were investigated. The toxic/harmful elements (cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), manganese (Mn), nickel (Ni), and zinc (Zn)) were determined in P. furfuracea. According to the analysis result, the maximum (max.) toxic/harmful element value was 62 ± 3.1 mg/kg for Mn and minimum (min.) value was 0.19 ± 0.01 mg/kg for Cd. The estimated daily exposure doses (EDEXDs) for men, women and children were dietary (bread) > dietary (tea) > dermal. For dietary (bread) and dietary (tea) non-carcinogenic (HQ) risk was children > women > men. For dermal, HQ risk was women > children > men. Hazard index (HI) value for men was >1 for Cr. HI value for men was 1.36 for Cr. HI value for women was >1 for Cr and Mn. HI values for women were 1.54 for Cr and 1.01 for Mn. Also, the HI value for children was >1 for Cr, Mn, and Pb. HI values for children were 3.44 for Cr, 2.24 for Mn, and 1.66 for Pb. This situation showed that there was a non-carcinogenic risk. Carcinogenic risk values were dietary (bread) > dietary (tea) > dermal. The total max. carcinogenic value was 1.97E-03 for Cr while the total min. carcinogenic value was 1.31E-05 for Pb. As a result, it has been determined that there may be a risk of cancer due to the consumption of lichen as bread and this situation may adversely affect human health.

  The use of Gammarus pulex as a model organism for ecotoxicological assessment of ibuprofen and propranolol at environmental relevant concentrations

  Cikcikoglu Yildirim, Nuran; Serdar, Osman; Basaran, Senay

  The aim of this study is to assess the toxicity of ibuprofen (IBU) and propranolol (PRO) drugs usingGammarus pulex as a model organism. Firstly, the 96 h LC50 values of IBU and PRO were determined and then three sublethal concentrations of the drugs were exposed to G. pulex. The activities of superoxide dismutase (SOD), catalase (CAT) and acetylcholinesterase (AChE) were evaluated. SOD activity decreased in G. pulex exposed to IBU and PRO compared to control. In all groups exposed to IBU, CAT activity increased at different concentrations at 24 and 96 h. In the groups exposed to different PRO concentrations, CAT activities increased after 24 h compared to the control group (p < 0.05). AChE activities increased in all application groups exposed to IBU for 96 hours (p < 0.05). In conclusion, exposure to IBU and PRO resulted in increased oxidative damage. PRO has been found to cause neurotoxicity.
