"Every rock has the potential to make water, especially after being irradiated by the solar wind," said William Farrell, a plasma physicist at NASA's Goddard Space Flight Center. NASA scientists measured the chemical components of water on the moon as they are going to put humans there in a...
Sources of chemical componentsA dew condenser was used to collect dew and frost samples to investigate the chemical properties of dew water for comparison with frost, rain and fog in Nanjing, China during the 2016-2017 winter. Twenty-three separate ambient dew samples were collected at a ...
The chemical composition of a material can be defined as the distribution of the individual components that constitute the material. The material can be a pure substance, which contains only one chemical component; in this case, the chemical composition corresponds to the relative amounts of the ...
Water-soluble inorganic components in rain deposited at the Maldives Climate Observatory Hanimaadhoo (MCOH) were examined to determine seasonality and possible source regions. The study, which is part of the Atmospheric Brown Cloud (ABC) project, covers the period June 2005 to December 2007. Air...
samples in the size range up to 2.5m were collected from January to December, 2005 at New Delhi, India, as a pilot experiment and analysed for organic (Oxalate and Formate) and inorganic (Sulfate, Ammonium, Nitrate, Potassium, Chloride, Sodium, Calcium and Magnesium) chemical components. Initi...
The chemical effects of road-deicing salt on soil and water were studied in five small, forested catchments in southeast Sweden. The use of deicing salt on... Stefan Lofgren - 《Water Air & Soil Pollution》 被引量: 211发表: 2001年 The 'principal components' statistical method as a compl...
The limiting value for drinking water is 0.01mg/L Se in Germany. 1.3 Calcium(Ca) But even a“common”element such as calcium Ca that is normally the main cation of surface-and shallow groundwater can be harmful.As an element of biologic importance it is an essential compound e.g.in bone...
Water is often addressed as a sustenance and the most essential fluid for human survival—and for all biological specimen survival. This begs the question, what is water made of? This section is dedicated to analyzing the components that make up the composition of water. Water is...
