Elevated levels of both nutrients and dissolved and suspended inorganic and organic matter, which are mainly generated from uneaten feed, fish excretion, and faecal production, might induce eutrophication in coastal zones (Holby and Hall 1991;Hall et al 1992;Wu 1995;Lee et al 2003).…”

Although water constitutes 71% of the earth's surface, only 0.3% of it is available as fresh water for human use. Moreover, the quality of fresh water in ground and surface systems is of great concern, as potable water needs to have appropriate mineral content. Ground and surface water quality in rural and urban environments is affected by both natural processes and anthropogenic influences. Because of this, water is becoming scarcer as the population increases across the world. Natural processes leading to changes in water quality include weathering of rocks, evapotranspiration, depositions due to wind, leaching from soil, run-off due to hydrological factors, and biological processes in the aquatic environment. These natural processes cause changes in the pH and alkalinity of the water, and also phosphorus loading, increase in fluoride content and high concentrations of sulphates. Anthropogenic factors affecting water quality include impacts due to agriculture, use of fertilizers, manures and pesticides, animal husbandry activities, inefficient irrigation practices, deforestation of woods, aquaculture, pollution due to industrial effluents and domestic sewage, mining, and recreational activities. These anthropogenic influences cause elevated concentrations of heavy metals, mercury, coliforms and nutrient loads. This paper studies the effects of natural processes and human influences in rural and urban aquatic systems. Pollution due to environmental parameters such as heavy metal pollution, heavy metals and bacterial and pathogenic contamination of both urban and rural areas is discussed in detail.

Summary: Increasing growth of the world's population, waste minimization policies and agricultural needs make the recycling of domestic wastewater quite a desirable practice. Factors like environmental and public health risks must be taken into account when considering treated wastewater for field irrigation and biosolids for land application. Wastewater disinfection is achieved via chlorination or UV-irradiation. In this study, an alternative disinfectant, gamma radiation is investigated. It is found that 60 Co-gamma irradiation could be effectively used for the disinfection of effluents from the municipal wastewater treatment plants, and gamma radiation dose of at least 5000 Gy was required for the inactivation Enterococcus sp., the most resistant bacteria among the indicator bacteria tested.Key words: Disinfection, gamma irradiation, indicator bacteria, municipal wastewater. Belediye arıtılmış atıksu ve biyokatılarında bulunan indikatör bakterilerin gama ışınlama ile inaktivasyonuÖzet: Dünya nüfusundaki artış, atıkların azaltılması politikası ve tarımsal gereksinimler evsel nitelikli atıksuların arıtılarak tekrar kullanımını istenen bir uygulama haline getirmiştir. Arıtılmış atıksuların tarım arazilerinin sulanmasında ve biyokatıların gübre olarak kullanımında ortaya çıkabilecek çevre ve halk sağlığına ilişkin risk faktörleri dikkate alınmalıdır. Atıksuların dezenfeksiyonu klorlama veya ultraviyole ışınlama ile sağlanmaktadır. Bu çalışmada gama ışınlama alternatif bir dezenfektan olarak araştırılmıştır. Sonuç olarak 60Co-gama ışınlamanın belediye arıtılmış atıksularının dezenfeksiyonunda etkili olduğu ve incelenen indikatör bakteriler içinde en dirençli olan Enterokok türleri dikkate alındığında en az 5000 Gy radyasyon dozunun uygulanması gerektiği belirlenmiştir.Anahtar sözcükler: Belediye atıksuyu, dezenfeksiyon, gama ışınlama, indikatör bakteri.

“…Cryptosporidium is diffi cult to detect with routinely used techniques, particularly due to its low concentration in water 9 . Method 1623 of the US Environmental Protection Agency 10 was developed for monitoring Cryptosporidium in water and consists of stages including fi ltration, concentration, immunomagnetic separation (IMS), and detection with DAPI and fl uorescent antibodies.…”
