a headspace-solid phase microextraction (hs-spme) and gas chromatography-mass spectrometry (gc-ms) method has been developed for the simultaneously determination of 20 disinfection by-products (dbps) in water samples from reverse osmosis (ro) membranes. selected compounds belong to different families including: trihalomethanes (thms), halogenated acetonitriles (hans), halogenated nitromethanes ...

BACKGROUND Previous studies have suggested that elevated exposure to disinfection by-products (DBPs) in drinking water during gestation may result in adverse birth outcomes. However, the findings of these studies remain inconclusive. OBJECTIVE The purpose of our study was to examine the association between blood biomarkers of late pregnancy exposure to trihalomethanes (THMs) in drinking water...

The behavioral toxicity of trichloromethane (TCM), dichlorobromomethane (DCBM), dibromochloromethane (DBCM) and tribromomethane (TBM) was evaluated following oral administration in mice. A variety of dosage regimens and behavioral measures were used. Studies included acute dose effect, 14-and 90-day treatments at 300 and 3000 times the estimated average human daily intake of contaminated drinki...

The quality of drinking water is highly dependent on physico-chemical and microbiological characteristics. This study envisaged to determine the consumed by population town Kenitra analyzing following parameters: Conductivity, Turbidity, Temperature, pH, Sulphates, Cadmium, Selenium, Arsenic, Fluorides, Total Iron, Manganese, Chloride Ions, Nitrates, Nitrites, Boron, Nickel, Trihalomethanes, Am...
