“…Despite the many benefits of wastewater and sludge use in agriculture, these practices can have adverse impacts on human health . Wastewater may contain contaminants that are harmful to health, such as metalloids/metals , excess nutrients, hormones , organic compounds such as pesticides, components of consumer products, pharmaceuticals and personal care products and, most importantly, pathogenic microorganisms .…”

ObjectiveTo review current evidence on infections related to the concentration of soil‐transmitted helminth (STH) eggs in wastewater, sludge and vegetables irrigated with wastewater or grown on sludge‐amended soils.MethodSearch of Web of Science, Science Direct, PubMed and Google Scholar databases for publications reporting on STH egg concentration in wastewater, sludge and vegetables and for epidemiological studies on wastewater/sludge reuse and STH infections.Results STH egg concentrations were variable but high in wastewater and sludge especially in developing countries. They ranged from 6 to 16 000 eggs/L in wastewater and from 0 to 23 000 eggs/g in sludge and far exceed limits set in the WHO guideline for wastewater/sludge reuse. Numbers of STH eggs on vegetables ranged from 0 to 100 eggs/g. The concentration of STH eggs in wastewater, sludge and vegetables therefore relates to risks of infection through different exposure routes.ConclusionEpidemiological evidence reveals an increased prevalence of STH infections associated with direct exposure to wastewater or sludge (farmers) and consumption of vegetables grown on soil treated with it. This calls for increased efforts to reduce the adverse health impact of wastewater and sludge reuse in line with the WHO multi‐barrier approach.

“…Also, Salmonella is one of the most-studied bacteria in WWTP sludge (Jr Krzyzanowski et al, 2016). These bacteria can survive once released into the environment in part through sludge spreading on agricultural plots (Jr Krzyzanowski et al, 2016;Bloem et al, 2017;Ellis et al, 2018). Thus, the consumption of food from these lands could be a way of contamination.…”

“…Thus, the consumption of food from these lands could be a way of contamination. It has been shown that even with low concentrations of Salmonella in sludge, some vegetables such as lettuce (Manios et al, 2013) and tomatoes (Asplund and Nurmi, 1991) may contain those bacteria in their tissues (Jr Krzyzanowski et al, 2016).…”

ÖZET: Bu çalışmada, atık suların mikroorganizmalardan arıtımı için alternatif olan ve son zamanlarda dikkat çeken yöntemler kullanılmıştır. Bu amaçla özellikle atık sularda yer alan Salmonella typhi RSHMB 96051 bakterisinin giderimi sonoliz, fotokataliz ve sonofotokataliz yöntemleri kullanılarak incelenmiştir. Yapılan denemelerde farklı ışık şiddetlerinin bakteri giderimindeki etkileri bu prosesler üzerinde çalışılmıştır. Denemelerde ultrases enerjisi ve ultraviyole ışınlar hem ayrı ayrı hem de eşzamanlı olarak birlikte kullanımlarıyla yapılmıştır. Bu prosesler sırasıyla sonoliz, fotokataliz ve sonofotokataliz prosesleridir. Elde edilen sonuçlar karşılaştırıldığında her üç tekniğin de bakteri gideriminde oldukça etkili olduğu ancak fotokataliz ve sonolizin birlikte kullanılmasıyla olan etkinin en fazla olduğu tespit edilmiş ve bu yöntemle %100 giderime yaklaşık 6 dakika gibi kısa bir sürede ulaşıldığı tayin edilmiştir.Anahtar Kelimeler: Atık su, fotokataliz, Salmonella typhi, sonofotokataliz, sonoliz ABSTRACT: In this study, some of the alternative methods have been utilized for the disinfection of microorganisms in the waste water. The disinfection of Salmonella typhi RSHMB 96051 bacteria in the waste water was investigated using the sonolysis, photocatalysis and sonophotocatalysis processes. In experiments, the effects of different light intentities have been investigated with the processes mentioned above. The ultrasound energy and ultraviolet light were used seperately and together as well. These processes are called sonolysis, photocatalysis and sonophotocatalysis respectively. The results yielded that all the processes were quite effective. The simultaneous use of sonolysis and photocatalysis yielded the best results. 100% disinfection ratio was obtained within 6 minutes in this study.
