Participants were asked to estimate (in numbers of 8-oz. glasses) their consumption of drinking water at home (separately through the study device and through all other sources at home) and outside the home.
Total glass of water consumption which assumed as the total consumption of the water supply in respondents' houses also did not have significant correlation with DNA damage.
The cement appears to trigger the glass dissolution by consumption of glass matrix components leading to a fast glass dissolution at a constant rate with the formation of a porous gel layer on the glass.
Building insulation is commonly realized using materials obtained from petrochemicals (mainly polystyrene) or from natural sources processed with high energy consumptions (glass and rock wools).
The beverages consumed will be calculated per unit of standard beverage (glasses), differentiating the consumption between working days and the weekend.

In order to elucidate the supply and consumption of glass during this transitional period, 31 glass samples from the assemblage found at Pergamon (Turkey) that date to the fourth to fourteenth centuries CE were analysed by electron microprobe analysis (EPMA) and by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS).
