Toxic Byproducts Generated in Disinfected Drinking Water Contaminated with Pharmaceuticals

Iodinated X-ray contrast media (ICM) were investigated as a source of iodine in the formation of iodo-trihalomethane (iodo-THM) and iodo-acid disinfection by-products (DBPs), both of which are highly genotoxic and/or cytotoxic in mammalian cells. ICM are widely used at medical centers to enable medical imaging of soft tissues (e.g., organs, veins, blood vessels), they are almost completely excr...

Modeling benzene permeation through drinking water high density polyethylene (HDPE) pipes.

Organic compounds such as benzene, toluene, ethyl benzene and o-, m-, and p-xylene from contaminated soil and groundwater may permeate through thermoplastic pipes which are used for the conveyance of drinking water in water distribution systems. In this study, permeation parameters of benzene in 25 mm (1 inch) standard inside dimension ratio (SIDR) 9 high density polyethylene (HDPE) pipes were ...

Acoustic Wave Propagation in Water Filled Buried Polyethylene Pipes

Axisymmetric acoustic wave-modes propagating along buried water pipes have been investigated by the method of finite elements and experimentally. High precision dispersion relations are presented in this paper as a function of the geometry, the embedding material and the elastic modulus of the pipes. It is found that at low frequencies the fundamental axisymmetric acoustic mode of the water cyl...

Mutagenicity and disinfection by-products in surface drinking water disinfected with peracetic acid.

The aims of this research were to study the influence of peracetic acid (PAA) on the formation of mutagens in surface waters used for human consumption and to assess its potential application for the disinfection of drinking water. The results obtained using PAA were compared to those found with sodium hypochlorite (NaClO) and chlorine dioxide (ClO2). The Ames test, root anaphase aberration ass...
