Özet: Bu çalışmada Karacabey (Bursa) ilçesi ve çevresinde yeraltısularının hidrojeokimyasal özellikleri incelenmiş ve sağlık risk değerlendirmesi yapılmıştır. İnceleme alanında yeraltısularının Ca-HCO3, Ca-Mg-HCO3 ve Mg-Ca-HCO3'lı sular fasiyesinde olduğu tespit edilmiştir. Mg artışı formasyonlar içerisindeki kumtaşı ve konglomera seviyeleri ile kaya-su etkileşiminden kaynaklanmaktadır. İnceleme alanında suların genel olarak fiziksel özellikleri ve anyon-katyon içerikleri açısından içme suyu sınır değerlerini aşmadığı tespit edilmiştir. Ancak, yeraltısularının As içeriği 9-79.1 µg/l arasında değişmektedir. As artışı genelde volkanik kayaçlarla ilişkili olarak jeojenik kökenlidir. Bazı lokasyonlarda NO3, Fe ve Mn içeriklerinin de içme suyu standart değerlerinin üzerinde olduğu tespit edilmiştir. Bu artışların jeojenik ve antropojenik kökenli olduğu düşünülmektedir. Çalışmada içme suyu sınır değerlerini aşan As, NO3, Fe ve Mn parametreleri için sağlık risk değerlendirmesi yapılmıştır. Su kaynaklarının oral (içme) ve dermal (deri) yolla alım ile gerçekleşebilecek tehlike katsayıları (HQ), tehlike endeksi (HI) ve kanser riski değerleri yetişkin ve çocuk bireyler dikkate alınarak hesaplanmıştır. Su kaynaklarının içmesuyu olarak uzun süreli kullanımında sağlık için olumsuz etki oluşabileceği tespit edilmiştir. As elementi açısından kanser riski olasılığı da bulunmaktadır.Abstract: In this study, the hydrogeochemical properties of the groundwater samples in the Karacabey (Bursa) district and surrounding were investigated and health risk assessment was performed. Groundwaters are Ca-HCO3, Ca-Mg-HCO3 and Mg-Ca-HCO3 facies. The increase of Mg is originated from water-rock interaction related to sandstone and conglomerate levels in different formations. In the study area, it is observed that the waters do not exceed the drinking water limit values in terms of physical properties and anion-cation contents. However, the As content of groundwater ranges between 9-79.1 µg/l. The increase of As is geogenic origin associated with volcanic rocks. In some locations, NO3, Fe and Mn contents were found to be higher than the drinking water standard values. These increases are thought to be of geogenic and anthropogenic origin. In this study, health risk assessment was made for As, NO3, Fe and Mn parameters which exceed drinking water limit values. Hazard Quotient (HQ), Hazard Index (HI) and Carcinogenic risk values of the spring waters for oral (drinking) and dermal (skin) intake were calculated by taking into consideration adult and child individuals. It has been determined that the long-term use of water resources as drinking water may have a negative impact on health. The carcinogenic risk may also be caused by the As element.

“…Cenozoic units are formed from marly limestone, conglomerate, andesitic lavas, trachyandesitic lavas, basaltic lavas, conglomerate, sandstone, siltstone and shale pyroclastics, alluvium, and travertine. Alluvium overlies older units, composed of uncemented clay, sand, silt, and gravel levels (Davraz et al, 2016).…”

Thermal muds have been used in many spas for the treatment of different diseases as well as to clean and beautify the skin and in different forms such as mud baths, masks, and cataplasms. Mineralogical and chemical compositions and the possible toxicity of the peloids were investigated and compared with some limits to determine whether they have any health benefits and potential applications for pelotherapeutic treatments. The studied peloid samples were collected from 19 spas in different parts of Turkey and they were classified as neutral to slightly alkaline, with a high electrical conductivity value that had a high chlorine content and was regarded as highly conductive. The temperature of the peloids was between 23.2 and 61.0 °C. The mineralogical composition mainly comprised smectite and illite, partially quartz and feldspar, some carbonate (calcite and dolomite), and other minerals. The most abundant clay mineral was Ca-montmorillonite. The major and trace element contents of some of the peloids were similar to each other, while the contents of some toxic elements showed a clear variation. Toxic element contents, e.g., As, Cd, Hg, Pb, and Sb, of the peloids were higher or lower than the commercial herbalist clay, pharmaceutical clay, natural clay, average clay, and Canadian Natural Health Products Guide. The toxicity of some hazardous elements was compared, especially that of the pharmaceutical clay, and evaluated together with other parameters. Toxic elements were higher than in the pharmaceutical clay in most of the peloids.
