Organic and volatile elements in the solar system

The organic Solar System.

In the first part of this two-essay series1 it was pointed out that over 100 different organic compounds have been detected in space, and that there are many locations in the Solar System where complex — and as yet uncharacterized — mixtures of organic molecules can be found. The Galilean moon Europa is a case in point. Its surface is stained with unsaturated polymers called tholins, which are ...

Origin of Elements in the Solar System

The solar system is chemically and isotopically heterogeneous. The earth contains only 0.0003% of the mass of the solar system, but the abundance pattern of non-radiogenic isotopes for each terrestrial element has been de-

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Solar System Abundances and Condensation Temperatures of the Elements

Solar photospheric and meteoritic CI chondrite abundance determinations for all elements are summarized and the best currently available photospheric abundances are selected. The meteoritic and solar abundances of a few elements (e.g., noble gases, beryllium, boron, phosphorous, sulfur) are discussed in detail. The photospheric abundances give mass fractions of hydrogen (X 1⁄4 0:7491), helium (...

The concentration of volatile organic compounds (VOCs) and related factors in the air in barbershops in Sanandaj in 2016

The aim of this study was to determine the density of benzene and toluene in barbershops of Sanandaj and also to determine effective factors for this pollution. A descriptive, analytical study was conducted to measure the volatile organic compound density and determine the effective factors. In this study, five hair salons and five barber shops were randomly selected from Sanandaj city. The vol...
