Abstract Swimming pools are popular entertainment and sport areas that people often use. For this reason, it is crucial to determine the physicochemical properties and Trihalomethanes (THMs) concentrations of swimming pools and the effect of THMs on swimmer health. This study focuses on the physicochemical parameters and THM concentrations of six swimming pools in Eskisehir and the impacts of THMs on human health. Within the study context, physicochemical parameters were examined and swimming pool water standards of various countries and organizations were evaluated. The alkalinity, pH, temperature, hardness, and free chlorine values of the swimming pools were determined to compare with the current standards. Concentrations of chloroform (TCM), bromodichloromethane (BDCM), and dibromochloromethane (DBCM) were also determined in the collected samples. Concentrations were found to be in the range of 11.6-100.1 µg/l for BDCM, 151.5-366.4 µg/l for TCM, ND-6.95 µg/l for DBCM, and 172.1-380.7 µg/l for TTHM. From the results, it was determined that TTHM concentrations were above the limit values defined by WHO, while chloroform (except P1 and P5 pools), BDCM (except P3 pool), and DBCM concentrations were significantly below the limit values. TTHMs and chloroform concentrations were high in tap water using sodium hypochlorite as a disinfectant. BDCM and DBCM concentrations were high in pools where groundwater was used. Health risks of THMs in pools through ingestion and dermal absorption were also estimated for both women and men. In the interpretation of the result, it was also found that high concentrations of TTHMs increased the risk, and women’s ingestion-based risk values are slightly higher than men’s ingestion-based risk values. Fingerprints of THM formation in pool water are precursor parameters and it is of great importance to constantly control and take precautions. It has been observed that the use of groundwater as a water source and NaCl as a disinfectant significantly reduces THM formation in swimming pools. However, in order to reduce the BDCM and DBCM concentrations in the use of groundwater, it is recommended to measure the precursor bromide and establish the relevant limit values. The use of hypochlorite disinfectants in pools where tap water is used as a water source increases THM formation. For this reason, it is necessary to determine the amount of organic carbon as a precursor for pools using tap water as a water source and add it to the limit values. In addition, the use of calcium hypochlorite disinfectant instead of sodium hypochlorite reduces THM formation. Highlight Physicochemical properties and THMs concentrations of swimming pools and effects of trihalomethanes (THMs) on the health of swimmers. Physicochemical parameters and THM concentrations of six swimming pools were determined, and the effects of THMs’ on human health.

Abstract Conventional testing methods provide sufficient information to evaluate human or ecological risk. However, contaminant concentrations patterns alone provide only limited resolution of important liability issues, such as when and where did contaminant releases originate. Over the past few decades, scientists explored the isotope applications to better identify, delineate, and manage contaminants in the environment. Advanced chemical fingerprinting and isotope technologies revealed important linkages between isotope ratios and contaminant origins (e.g., chemical feedstock and manufacturing process). Studies of environmental weathering distinguished abiotic and biotic changes in the chemical composition and isotope patterns. The combined application of chemical and isotopic fingerprints offers powerful complementary lines of evidence for delineating contaminants, assessing risk, and identifying historical sources. This manuscript provides an integrated forensic approach that systematically links conventional environmental investigation data with specialized chemical fingerprinting and carbon/chlorine isotope methods for identifying the sources of groundwater impacts especially when multiple potential point and non-point sources exist. This paper focusses on chlorinated solvents. Specifically, it features the synoptic use of chemical concentration patterns and compound-specific isotope analysis (CSIA) as effective tools for confirming organic contaminant sources, characterizing environmental weathering, and answering a growing list of site-specific questions. Unlike conventional isotope methods, which can be both time-consuming and expensive, this paper presents an optimized analytical method for chlorine CSIA using gas chromatography-quadrupole mass spectrometry (GC-qMS). Chlorine isotopic composition for multiple analytes (e.g., tetrachloroethylene [PCE], trichloroethylene [TCE], dichloroethylene [DCE], and vinyl chloride [VC]) can be determined in one acquisition thus reducing analysis time and cost. Precise CSIA isotope values were achieved for chloroethylene concentrations between approximately 5 micrograms per liter (ug/l) and 100 ug/l for carbon and between approximately 30 ug/l to 1,000 ug/l for chlorine. The gradual improvement in CSIA methods better addresses the wide concentration range encountered in typical samples collected from groundwater aquifers with significant chlorinated solvent impacts. A case study is presented featuring a tiered forensic investigation using spatial chemistry and isotope patterns to evaluate commingled plumes of PCE and TCE.

Abstract

The soot emitted from diesel vehicles has been identified as a significant source of air pollution. The characteristics of the soot indicate its ability to alter the air quality of the area. This study compared the characteristics of soot particles emitted from two commonly used public transport; diesel-driven school bus (SB) and the shared auto-rickshaw (AR). The differences were found in the soot particles from the SB and AR. The FESEM (field emission scanning electron microscope) reveals that the morphology of the soot particles from both vehicles were spherical. The average size of soot was 207.30 nm (AR) and 251.65 nm (SB). This extreme small-size soot is dangerous to human health. The ratio of oxygen and carbon (O/C) was found as 0.51 and 0.26 in soot samples of AR and SB, respectively. The sharper peaks in FTIR (Fourier transform infrared spectroscopy) show that the functional groups in AR soot were in higher quantity compared to soot of SB. The concentration of total trace metals (TM) (Cu, Cr, Cd, Fe, Ni, Pb, and Zn) was 1.08 times less in soot collected from AR than SB. The study signifies that the characteristics of soot emitting from AR and SB can be utilized as a fingerprint of ambient pollution and it will be helpful in controlling PM emissions.

摘要柴油车排放的烟尘已被确定为空气污染的重要来源。煤烟的特性表明它有能力改变该地区的空气质量。本研究比较了两种常用公共交通工具排放的烟尘颗粒特征;柴油校车(SB)和共享机动三轮车(AR)。通过场发射扫描电镜(FESEM)分析发现,两种车辆的烟尘颗粒形貌均为球形。烟尘的平均粒径为207.30 nm (AR)和251.65 nm (SB)。这种极微小的煤烟对人体健康是有害的。AR和SB烟尘样品的氧碳比(O/C)分别为0.51和0.26。红外光谱的尖锐的峰值(傅里叶变换红外光谱学)表明,AR烟尘的官能团是更高的数量相比,烟尘某人总微量金属的浓度(TM)(铜、铬、Cd、铁、镍、铅、锌)1.08倍不如某人烟尘收集从基于“增大化现实”技术。研究表明,烟尘排放的特点从AR和某人可以利用指纹的环境污染,它将有助于控制PM排放。
