The current work focused on the water quality of Bega and Timis rivers measured by two methods. One them is method which was analyzed from a physical-chemical point view, other aimed at quantifying degree pollution biological In this sense, diatoms were used. study, samples taken using specific techniques rivers, starting near area their formation until border with Serbia. Four sampling points ...

Library-dependent (LD) (biochemical fingerprinting of Escherichia coli and enterococci) and library-independent (LI) (PCR detection of human-specific biomarkers) methods were used to detect human faecal pollution in three non-sewered catchments. In all, 550 E. coli isolates and 700 enterococci isolates were biochemically fingerprinted from 18 water samples and compared with metabolic fingerprin...

Oil extraction may cause extensive environmental impact that can affect health of populations living in surrounding areas. Large populations are potentially exposed to oil extraction related contamination through residence in areas where oil extraction is conducted, especially in low and middle income countries (LMICs). Health effects among people residentially exposed to upstream oil industry ...

To design and implement policy to manage water quality, it is important to investigate land use and possible sources of pollution. In this study, using Pearson regression analysis, redundancy analysis and multiple regression analysis, we assess the influence of land use and point sources on water quality in the river system in Shunde district in 2000 and 2010. The results show that water qualit...

UNLABELLED F-specific RNA phages (FRNAPHs) are considered potential viral indicators of water pollution due to their occurrence and stability in water environments. However, their suitability as viral indicators is not fully elucidated because the characteristics of FRNAPHs are variable depending on the genotype. In this study, for the characterization of infectious FRNAPH genotypes, integrated...
