Although, the safe limits of human daily boron (B) exposure are not absolutely clear, there is a growing interest in B and its effects on human health. The aim of the present study was to estimate daily B exposure in 66 males in Turkey living in a B-rich area using water containing at least 2 mg/1 boron, with an average age of 38-55 (SE 1.66) years and an average number of years of residence in the B-rich area of 35-89 (SE 1.73). Another group of males (n 57), living in the city centres of Balikesir and Ankara, were taken as controls; the average age and number of years of residence for this group were 29-44 (SE 1-43) and 10-26 (SE 1.83) years, respectively. As it is assumed that the B level in urine reflects daily B exposure, the amount of urinary B of both the study and control groups was analysed by using an inductively coupled plasma optical emission spectrometry (ICP-OES) technique. The average daily B exposure value was calculated as 6.77 (SE 0.47) mg in the study group and 1.26 (SE 0-1) mg in the controls. The results of this study are expected to contribute to creating a reference value for a safe daily B exposure.

Assessment of health risks associated with the consumption of wastewater-irrigated vegetables in urban areas
Jabeen, F.; Manzoor, M.; Ibrahim, M.; Mahmood, A.; Adrees, M.; Aslam, A.; Kanwal, U.; Vithanage, M.; Yousaf, Balal (2022-08-01)
Several health issues are related to toxic metals among which Pb, Cr, Cd, and Ni are categorized as human carcinogenic. We analyzed the health risks linked with food chain contamination due to vegetables irrigated with wastewater containing metals. Thirty-six samples of each vegetable, water, and soil (at two depths, 0-15 cm, and 15-30 cm) were collected individually from 12 different locations near Paharang drain, Faisalabad, and the contamination level of each metal (Cd, Cr, Mn, Ni, and Pb) was determined...
Review of factors impacting emission/concentration of cooking generated particulate matter
Torkmahalleh, Mehdi Amouei; Gorjinezhad, Soudabeh; Unluevcek, Hediye Sumru; Hopke, Philip K. (2017-05-15)
Studies have shown that exposure to particulate matter (PM) emitted while cooking is related to adverse human health effects. The level of PM emissions during cooking varies with several factors. This study reviewed controlled studies available in the cooking PM emissions literature, and found that cooking method, type and quality of the energy (heating) source, burner size, cooking pan, cooking oil, food, additives, source surface area, cooking temperature, ventilation and position of the cooking pan on th...
Reproductive toxicity parameters and biological monitoring in occupationally and environmentally boron-exposed persons in BandA +/- rma, Turkey

Boric acid and sodium borates have been considered as being "toxic to reproduction and development", following results of animal studies with high doses. Experimentally, a NOAEL (no observed adverse effect level) of 17.5 mg B/kg-bw/day has been identified for the (male) reproductive effects of boron in a multigeneration study of rats, and a NOAEL for the developmental effects in rats was identified at 9.6 mg B/kg-bw/day. These values are being taken as the basis of current EU safety assessments. The present...
Evaluation of Heavy Metals and Associated Health Risks in a Metropolitan Wastewater Treatment Plant's Sludge for Its Land Application
Kendir, Ece; Kentel Erdoğan, Elçin; Sanin, Faika Dilek (2015-08-18)
The objectives of this study are to monitor the heavy metal concentrations in sludge samples collected from the Ankara Central Wastewater Treatment Plant (ACWWTP) in Turkey, check if these concentrations comply with the Turkish Regulation (Regulation Regarding the Use of Domestic and Urban Sludges on Soil), and evaluate possible health risks of heavy metals in sludge due to ingestion of sludge by a child. Monthly sludge samples were collected from the ACWWTP during 2012 and analyzed for seven heavy metals (...
Evaluation of Performance of Arsenic Bioreporter Immobilized Electrospun Membranes for Arsenic Detection in Water
Arık Kınalı, Nehir; Öktem, Hüseyin Avni; Tezcaner, Ayşen; Department of Molecular Biology and Genetics (2022-12-9)
Heavy metal pollution, which is growing and threatening the health of all living things as well as human health, can lead to serious lifelong consequences. It is very important to detect and monitor these heavy metals that cause environmental pollution. In addition to traditional laboratory techniques, the use of bacterial biosensors to detect heavy metals has come into focus. In addition, it is known that the immobilization of these bacterial biosensors is more advantageous in many respects, such as being ...
