background: measurement of back ground concentration of uranium in drinking water is very important for many reasons, specially, for human health. the uranium concentration in drinking water in many counties is a matter of concern for clinical and radioactive poisoning. materials and methods: the uranium concentration in drinking water is determined using laser flourimatric uranium analyzer. fo...

We analyzed 1,042 Cryptosporidium oocyst-positive slides (456 from raw waters and 586 from drinking waters) of which 55.7% contained 1 or 2 oocysts, to determine species/genotypes present in Scottish waters. Two nested PCR-restriction fragment length polymorphism (RFLP) assays targeting different loci (1 and 2) of the hypervariable region of the 18S rRNA gene were used for species identificatio...

This review summarizes major findings over the last decade related to nitrosamines in drinking water, with a particular focus on N-nitrosodimethylamine (NDMA), because it is among the most widely detected nitrosamines in drinking waters. The reaction of inorganic dichloramine with amine precursors is likely the dominant mechanism responsible for NDMA formation in drinking waters. Even when occu...

INTRODUCTION Drinking waters usually contain several natural radionuclides: tritium, radon, radium, uranium isotopes, etc. Their concentrations vary widely since they depend on the nature of the aquifer, namely, the prevailing lithology and whether there is air in it or not. AIMS In this work a broad overview of the radioactivity in drinking water is presented: national and international regu...
