“…The autochthonous limestone is situated to the southeast of the Lycian overthrusted front. Slices show the ophiolitic melange feature at the bottom of this structure (Ekmekçi, 2005;Davraz et al, 2008). Important springs are located mostly along the tectonic contact between overthrusted limestone formations and impervious hydrogeological barriers (Gunay et al, 2015).…”

Abstract. Flash floods are caused by heavy rainfall that has become more frequent. They are more prominent in lowstorage karst regions, although karst terrain often acts as a natural flood control particularly when it is bare and dominated by conduits. A study using a hydrogeochemical approach and assessing data from several springs in different carbonate rock in western Turkey has made it possible to classify karst aquifers based on their response to heavy rainfall events. According to this aim, physico-chemical measurements in wet and dry seasons and discharge rates in springs are compared in order to explain aquifer characteristics. Groundwater samples have a pH ranging from 6.3 to 8.9, temperature (T ) varying from 7 to 35 • C and electrical conductivity (EC) ranging from 140 to 998 µs cm −1 . Groundwater samples with high EC, high T and low dissolved oxygen (DO) represent the deep circulating water, while low EC, low T and high DO are linked to the shallow circulating water. Lower variability between wet and dry seasons reveals that fracture permeability is predominantly controlled by diffuse groundwater flow with low or high storage, and conduit permeability with high storage. However, variability of the physico-chemical characteristics is higher in a conduit permeability with low storage. These types of aquifers with high transfer capability, predominantly controlled by turbulent groundwater flow, affect flash floods.

“…Apart from the highly valuable heritage that may constitute the karst landforms and waters, the interaction between human activity and the karst environment has led to many detrimental effects on the natural resources (Ekmekci 2005;Jiang et al 2008;Miko et al 2008). Karstic environments are extremely sensitive to subtle anthropogenic changes, which may lead to unwanted effects in short periods of time (Jiang et al 2008;Parise et al 2008).…”

Organochlorine pesticides (OCPs) in the air of Dayan Cave in Guilin were analyzed, to investigate the source and contamination levels. Generally, air outside of the cave had much higher concentrations than inside air, and both outside and inside air showed much lower contamination levels than those observed in other regions in China and abroad. The ratios of α-/γ-HCHs and the percentages of β-(or δ-)HCH implied a residue of historical local technical HCH contamination. The DDT concentrations, o,p'-DDT/p,p'-DDT, and p,p'-DDE/p,p'-DDT suggested fresh DDT-containing products acted as the primary source of DDT for the air in Dayan Cave. An intermediate level concentration of α-endosulfan (156.00 pg/m(3)) was observed in the outside air, implying local source was dominant. Based on the similar sources of HCH and DDT and the relationships between outside and inside air, it appeared that outside air pollutants affected on inside HCH and DDT's distribution. For other OCPs, outside air might be major contributor to inside air contamination under conditions of high concentrations in outside air compared with low levels in inside air for semi-closed karstic caves.

“…Furthermore, large numbers of interconnected fissures can make pollutions spread quickly and widely in a karst system (LeGrand 1984;Prohic 1989;Ford 1993). Muhayimana et al (2009) andWang et al (2011) analyzed OCPs in soils in a karst area while Ekmecki (2005) found pollution from OCPs in karst springs waters. Beside these researches of OCPs, nutrient transports have been reported extensively.…”

Sources and transports of organochlorine pesticides in the Nanshan underground river, China

Karst areas have much higher ecological vulnerability and are prone to be contaminated. Organochlorine pesticides (OCPs) were detected in waters and sediment from the two sites of the karst Nanshan underground river system, China, to understand the sources and transport of OCPs in the underground river systems. Obviously, seasonal variations were found both in the waters and the sediments. Detected OCPs ranged from 61 to 936 ng L -1 in the groundwaters and 51-3,842.0 ng g -1 in the underground sediments, respectively. OCPs in groundwaters were mixture of younger and older residues from commercial sources. The maximum OCPs in the sediments of the underground river were historically older residues from commercial sources. The sources of OCPs in the waters and sediments of the underground river indicated that the surface systems play an important role in OCPs transport and pollution in the underground river. Karst features were liable for the transport behavior.
