Abstract Blue carbon ecosystems provide a wide range of ecosystem services, are critical for maintaining marine biodiversity and may potentially serve as sites economically viable dioxide removal through enhanced organic storage. Here we use biogeochemical simulations to show that restoration these can also lead permanent by driving ocean alkalinity enhancement atmosphere-to-ocean CO 2 fluxes. ...

background & aims of the study: corrosion and scaling play undesirable effects on transmission and distribution system of drinking water. the aim of this study was to assess the corrosion and scaling potential of drinking water resources in babol city. materials and methods: totally, 54 water samples were collected from 27 wells in spring and autumn. calciu m hardness, ph, total alkalinity, tot...

A steady state model for anaerobic digestion of sewage sludge is developed that comprises three sequential parts – a kinetic part from which the % COD removal and methane production are determined for a given retention time; a stoichiometry part from which the gas composition (or partial pressure of CO2), ammonia released and alkalinity generated are calculated from the %COD removal; and a carb...

Possible appliance of effective and safe alkalizing agent in the treatment of metabolic acidosis could be of particular interest to humans experiencing an increase in plasma acidity, such as exercise-induced acidosis. In the present study we tested the hypothesis that the daily oral intake of 2L of hydrogen-rich water (HRW) for 14 days would increase arterial blood alkalinity at baseline and po...
