Book Part Medical Geology Outreach: a Major Success Story From Turkey(Springer International Publishing, 2021) Baba,A.; Finkelman,R.B.It is incumbent upon medical geology practitioners to reach out to students, science faculties, decision makers, and the biomedical/public health communities to promote this emerging discipline. Perhaps the most successful of these efforts have taken place in Turkey where medical geology courses have been offered in four medical and ten engineering faculties. As a result of these outreach efforts by the Turkish medical geology community for the past decade, there has been robust interactions with scientists from many disciplines and collaborative research on groundwater quality, asbestos, radon, arsenic, mesothelioma, fluorosis, etc. © Springer Nature Switzerland AG 2021.Book Part Citation - Scopus: 1Naturally Occurring Arsenic and Boron in Geothermal Systems and Their Health Effects: a Case Study From Turkey(Springer International Publishing, 2021) Baba,A.; Recepoglu,Y.K.; Yazdani,H.Human beings have benefited from geothermal energy for different uses since the dawn of civilization in many parts of the world. However, the highest concentrations of naturally occurring aqueous arsenic (As) and boron (B) are found in certain types of geothermal fluids, generally those related to faults and volcanic activity which have caused wide-ranging alteration from argillic type to silica type. The argillic alteration zones are typically enriched in sulfur in volcanic rocks. Also, epithermal systems, which have a high concentration of As in the form of realgar and orpiment along the fracture zones of metamorphic and carbonate aquifers. On the other hand, B can easily rise to the surface by hydrothermal activity or concentrate in residual magma fluids or coexisting liquid and gas phases depending on the geology. The concentration of As and B in geothermal fluids changes in each geothermal field because of the geological properties of the region. For example, the concentration of As in geothermal fluids ranges from 10 μg/L to 50 mg/L in different parts of world whereas the concentration of B ranges from 0.04 to 119 mg/L. This chapter describes the sources and behavior of As and its relationship to elements such as B and chlorine (Cl−) using data from the samples taken from boiling and warm hot springs and geothermal wells in different geothermal fields in Turkey to evaluate their environmental impacts. © Springer Nature Switzerland AG 2021.Article Citation - Scopus: 5Risk Analysis for Groundwater Intakes Based on the Example of Neonicotinoids(Elsevier Ltd, 2024) Pietrzak,D.; Kania,J.; Kmiecik,E.; Baba,A.Neonicotinoids are a class of broad-spectrum insecticides that are dominant in the world market. They are widely distributed in the environment. Understanding the sources, distribution, and fate of these contaminants is critical to mitigating their effects and maintaining the health of aquatic ecosystems. Contamination of surface and groundwater by neonicotinoids has become a widespread problem worldwide, requiring comprehensive action to accurately determine the mechanisms behind the migration of these pesticides, their properties, and their adverse effects on the environment. A new approach to risk analysis for groundwater intake contamination with emerging contaminants was proposed. It was conducted on the example of four neonicotinoids (acetamiprid, clothianidin, thiamethoxam, and imidacloprid) in relation to groundwater accessed by a hypothetical groundwater intake, based on data obtained in laboratory tests using a dynamic method (column experiments). The results of the risk analysis conducted have shown that in this case study the use of acetamiprid and thiamethoxam for agricultural purposes poses an acceptable risk, and does not pose a risk to the quality of groundwater extracted from the intake for food purposes. Consequently, it does not pose a risk to the health and life of humans and other organisms depending on that water. The opposite situation is observed for clothianidin and imidacloprid, which pose a higher risk of groundwater contamination. For higher maximum concentration of neonicotinoids used in the risk analysis, the concentration of clothianidin and imidacloprid in the groundwater intake significantly (from several to several hundred thousand times) exceeds the maximum permissible levels for drinking water (<0.1 μg/L). This risk exists even if the insecticides containing these pesticides are used according to the information sheet provided by the manufacturer (lower maximum concentration), which results in exceeding the maximum permissible levels for drinking water from several to several hundred times. © 2024 Elsevier LtdArticle The Relation of Geogenic and Antrophogenic Factors With Blood and Hair Lead and Arsenic Levels in Women Living in Çan and Bayramiç Districts of Çanakkale Province(Nobelmedicus, 2019) Baba, Alper; Gündüz, Orhan; Bakar, Çoşkun; Sülün, Serdar; Save, DilşadObjective: Mining areas and associated industrial activities carry considerable risks for human health due to multi-pathway exposure of heavy metals such as arsenic and lead. The objective of this study was to compare arsenic and lead levels in human blood and hair samples in an industrial mining area in northwestern Turkey with that of a non-exposed group demonstrating similar sociocultural characteristics. Material and Method: The population of the study consisted of 674 nonsmoker women over the age of 40 who were selected on a random basis from mine region and control area. Venous blood samples were taken and analyzed for blood lead and arsenic levels in all participants. Hair samples were later collected from 108 women with high levels in blood samples. Results: The results showed that the highest prevalence of occurrences was found in district centers whereas relatively lower values were observed in the villages. Hair arsenic and lead levels were comparably higher in the industrialized area (Çan Region) where low-quality coal combustion used in power generation and residential heating were dominant. Conclusion: Although high correlations were not found, blood and hair arsenic and lead levels in individuals living in industrial and agricultural areas were found to be high at levels influencing the human health. On the other hand, these results should be further supported and verified with advanced and long duration monitoring activities.
