OBJECTIVE To assess the extent of arsenic contamination of groundwater and surface water in Peru and, to evaluate the accuracy of the Arsenic Econo-Quick(™) (EQ) kit for measuring water arsenic concentrations in the field. METHODS Water samples were collected from 151 water sources in 12 districts of Peru, and arsenic concentrations were measured in the laboratory using inductively-coupled pl...

groundwater is a major source of water for domestic, industrial, and agricultural sectors in many countries. the main objective of this research was to provide an overview of present groundwater quality using parameters such as calcium, magnesium, sodium, chloride, sulfate, ph, and electrical conductivity (ec) in the mehran plain, ilam province using gis and geostatistical techniques. a total o...

readymade garment industries are the prominent economic sector for bangladesh as well as scoping the huge working area for workers. but health condition of workers, drinking water quality, and proper maintenance of the environmental parameters are not well monitored. this study aims to assess the physio-chemical and bacteriological quality of drinking water provided for the garment workers in d...

this study was conducted to investigate the characteristics of input and output wastewater of the bandargaz wastewater treatment plant on the basis of the data collected during operation and the samples taken during the study period. for this purpose, three samples were taken from the outflow wastewater and 25 quality parameters were tested. also, four soil samples were taken from the soils whi...

A capillary electrophoresis system for the simultaneous determination of cations in honey samples has been developed. The complete separation and quantification of K+, Ca2+, Na+, Mg2+, Mn2+, Ni2+ and Li+, which represent more than 99% of the total content of cations in honey, can be achieved in 4 min with only a dilution and filtration of the honey sample. Electrolyte solution was composed by 1...

tion dates back to the mid 18th century. Chlorinated lime and chlorine gas have since been used for conventional disinfection of municipal drinking water for the prevention of epidemic diseases such as cholera and typhoid.1–3 Generation of chlorine by electrolysis of aqueous NaCl solution had come into use by the end of the 19th century. The advantage of the electrolysis is that transportation ...

conclusions the ppi-g2 dendrimer with end amine groups exhibited a positive impact on the removal of dominant bacterial isolated strains. therefore, it is possible to use these nanodendrimers as a safe and effective material for water disinfection in the future. results the most important isolated bacteria were escherichia coli 37 (48.7%), klebsiella oxytoca 12 (15.8%), proteus mirabilis 3 (4%)...
