The Balikligol Lakes in Sanliurfa, Turkey (Lake Ayn-i Zeliha and Lake Halil-ur Rahman) are freshwater lakes, which possess not only environmental value but also touristic value due to their natural aquarium look and their historical and sacred status in the past and present. From time to time, fish deaths have been encountered in these lakes. Deteriorating water quality could harm the health of the fishes in the water. Therefore, the water quality at both of the lakes needs to be monitored. The pollution at the lakes exceeding the acceptable levels endangers the sustainable management of the living creatures.
With the advent of the measurement technology, it is now possible to set-up permanent monitoring systems for varieties of parameters in cost-effective way. The objective of this study is to establish a preemptive warning system against a possible pollution in the Balikligol Lakes (Lake Ayn-i Zeliha and Lake Halil-ur Rahman). In this regard, the locations of the eight measuring stations for keeping track of the pollution levels have been selected. The applicable system units were determined. Then, each station will make predetermined measurements and send data to the Environmental Administration Center of Sanliurfa Governorship via wireless internet connection. The Lakes’ closeness to the city center makes the wireless internet access available. Moreover, the measuring station locations were geocoded on a digital map, and Information tables for each station were linked to the digital map by use of Geographic Information System (GIS) software. The basic approach of the system is that the collected data at the Environmental Administration Center will be analyzed with the support of GIS enabled software, and the action plan will be determined according to the guideline established for the surface water quality standards. This whole process will create a management system for The Balikligol Lakes which receives real-time data continuously and respond promptly according to the guideline.

Optische Methoden ermöglichen neuen Blaualgen-Schnelltest
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (12/2021)
Verfärbt sich im Sommer das Wasser in Badeseen und Teichen grün, dann handelt es sich dabei oft um Blaualgen. Diese können für Mensch und Tier gefährliche Gifte in sich tragen, so dass immer wieder Gewässer von den Behörden schon vorsorglich gesperrt werden müssen. Ein Physiker- und
Physikerinnenteam arbeitet an der Leibniz Universität Hannover an einem Schnelltest, um die giftigen Blaualgen schon vor Ort sicher von den harmlosen zu unterscheiden. Damit können die Kosten für Wasseruntersuchungen gesenkt und unnötige Gewässersperrungen vermieden werden.
Die Bewertung der Belastungen des Sees Cerknica durch Stickstoff und Phosphor
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (12/2009)
Der See Cerknica ist ein periodischer See mit einer Oberfläche von 26 km2 und einem Volumen von 80 km3. Die gesamte Umgebung umfasst 270 km2 mit einer Population von 15 000 Einwohnern. In diesem Beitrag werden natürliche und anthropogene Belastungen des Sees mit Stickstoff und Phosphor behandelt. Es wurde festgestellt, dass die größte Belastung aus der Landwirtschaft resultiert, die 85 % des Phosphors und 87 % des Stickstoffs beisteuert. Der Rest kommt von den kommunalen Kläranlagen, wobei die Industrie nur einen unbedeutenden Anteil von 1 % beiträgt.
Ecotoxicity of a point source pollution of Lake Como (Northern Italy)
© Aristotle University of Thessaloniki (6/2009)
Lake Como is the deepest and the third largest lake in Italy, which lies in an important industrial and commercial area of Northern Italy. The main activities concern textile factories and clothing and, of slight importance, metal manufacturing. In the Southern part of the Como branch of the lake, where waters are withdrawn for potable use, the inlet of Torrent Cosia represents an important source of known and unknown substances potentially dangerous for freshwater organisms and for human uses.
Ecotoxicity of sea bream (Sparus aurata L. 1758) and sea bass (Dicentrarchus labrax L. 1758) aquaculture spills located in Cádiz Bay (SW of Spain)

The rise on worldwide population requires a bigger amount of resources, including aquaculture. This fast growing necessitates responsible management of aquaculture wastes, as methods to determine which concentrations alters the normal development of farm surrounding areas. Farming of sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) have incremented considerably compared with other species in South of Spain, mainly due to appearance of new intensive growing technologies.
Comparative dredged material characterization using sea urchin embryogenesis and fertilization bioassays in Spanish commercial ports

Dredged material contamination (Hg, Cd, Pb, Cu, Zn, As, Ni, Cr, and PCBs, PAHs and TBT) was evaluated in different commercial ports from Spain: Ports of Cádiz and Huelva (Southwest), Santander (North) and Barcelona (Northeast).
