Volatilization of Organic and Inorganic Compounds

Volatilization of naturally formed gases (e.g., H2S, C02, CH4, NH3) represents a removal process 

Another form of removal through the water-atmosphere interphase is aerosol formation in marine surface waters where salt spray tends to remove mainly NaCl, NaS04, and MgS04. These are generally known as cyclic salts due to their potential return to the sea through rain washout. 

All the concepts and examples presented in this chapter refer to natural phenomena in the hydrosphere, and are basic for understanding the dynamics, quality, and characteristics of aqueous systems. They are also relevant for understanding what may happen to these natural systems that could alter, deviate, or intensify the natural processes when other types of substances or conditions are introduced by anthropogenic activities and pollution processes. These issues are further discussed in Chapter 8, where we will consider the impact of these activities on the surrounding systems and the resulting chemical processes.
