The initial tap water database of 24 sites has been subsequently increased to the final number of 157 distributed all over Italy and representative of end-user situations (either private houses and public places). In the samples, pH, conductivity and concentrations of 69 elements (Ag, Al, As...
In some waters higher content of B, I, NH4, as well as of Tl and W has been observed which can be attributed to water's circulation through different lithological complexes. Tap water was mostly obtained from groundwater (from Neogen and alluvial aquifers and karst springs) with rest being...
A retrospective case-control study was conducted to test the hypothesis that there is an association between the trace element content of domestic tap water and neural tube malformations in infants. Of 11 elements examined a notable difference was found only for zinc, this being lower in the case...
Representative samples of tap water were collected in 48 local-authority areas in South Wales. The associations between twelve trace elements and both total and ischæmic-heart-disease (I.H.D.) mortality were examined. Interrelationships between the trace elements were found to be strong and co...

However, boreholewater should be used if other water sources (tap water etc.) were notavailable. All the industries near Huruma estate should carefully analyze andregularly monitor their liquid waste effluents to ensure that no harmfuldischarges get into the soil....
In the middle of the night, I can hear a dripping tap a hundred yards away though three closed doors. How come I never hear the sounds in the daytime? I'm quite clear in my mind what the good sounds are and what the bad sounds are. I've turned against whistling(吹口哨), for ...
We find that remodelers bear a functional element named the ‘ruler’ that determines spacing and phasing in a remodeler-specific way. We use structure-based mutagenesis to identify and tune the ruler element residing in the Nhp10 and Arp8 modules of the INO80 remodeler complex. Generally, ...
