“…Chlorine disinfection leads to the formation of toxic disinfection byproducts, though at trace concentration levels (Sedlak and von Gunten 2011). Boiling tap water slightly improved the CHN results, which might be associated with partial removal of chlorine or these volatile byproducts (Zhang et al 2015, Liu et al 2020). Water fountain uses tap water as the source.…”

Hydration plays a particularly important role in health maintenance and general well-being. A wide assortment of drinking waters are currently available on the market. However, their ability to hydrate may vary. For studying hydration, a useful organism may be the cysts of brine shrimp. Those cysts may remain dehydrated and functionless for years, but regain function once hydrated. In this study, we first determined the optimal factors for assessing hydration in the brine-shrimp model, including aeration method and flow rate, salinity, and temperature. Various kinds of water, including tap water, bottled water, and water containing health-promoting agents, were tested by using this new method to evaluate their ability to hydrate. Tap water showed weak hydration, while some bottled waters (e.g., Kirkland Signature Purified Water) hydrated more effectively. Mineral water, such as Fiji water, was found to be a desirable option to maintain adequate and lasting hydration.Graphic abstract

“…After 1 h of heating at 80 °C, the aggregate THM concentration of Tap water A containing 10.0 g L −1 Salt-1 and Salt-2 decreased by 16% and 15% to 86.3 ± 1.2 μg L −1 and 88.1 ± 2.7 μg L −1 , respectively, due to the hydrolysis and volatilization of THMs. 24 Of note, the formation of brominated THMs was much less than that of I-THMs, which might be attributed to the lower bromide content in seaweed salt.…”

“…Drinking boiled water is an ancient tradition in some Asian countries such as China, Vietnam, and Indonesia; , however, tap water (or filtered tap water) is often consumed directly in many western developed countries . Boiling or heating tap water is able to remove trace pollutants such as disinfection byproducts , and some metal ions (e.g., Ca 2+ , Cu 2+ , and Mg 2+ ). , Boiling water with certain hardness and alkalinity commonly produces incrustants dominated by insoluble calcium carbonate (CaCO 3 ). Nano/microplastics could be encapsulated by newly generated CaCO 3 , coprecipitating in aquatic ecosystems, and could even promote CaCO 3 biomineralization .…”

Tap water nano/microplastics (NMPs) escaping from centralized water treatment systems are of increasing global concern, because they pose potential health risk to humans via water consumption. Drinking boiled water, an ancient tradition in some Asian countries, is supposedly beneficial for human health, as boiling can remove some chemicals and most biological substances. However, it remains unclear whether boiling is effective in removing NMPs in tap water. Herein we present evidence that polystyrene, polyethylene, and polypropylene NMPs can coprecipitate with calcium carbonate (CaCO 3 ) incrustants in tap water upon boiling. Boiling hard water (>120 mg L −1 of CaCO 3 ) can remove at least 80% of polystyrene, polyethylene, and polypropylene NMPs size between 0.1 and 150 μm. Elevated temperatures promote CaCO 3 nucleation on NMPs, resulting in the encapsulation and aggregation of NMPs within CaCO 3 incrustants. This simple boiling-water strategy can "decontaminate" NMPs from household tap water and has the potential for harmlessly alleviating human intake of NMPs through water consumption.
