The Lavosier Mass Balance

2 THE CHEMICAL SPECIES CONTINUITY EQUATION 2.2.1 The Lavosier Mass Balance 

The conservation of mass, performed by applying the Lavosier species mass balance to chemicals in the natural media, is the basic concept underlying environmental chemodynamics. The species CE is the result and is a good context in which to present the various types of chemical mass transport processes needed for environmental chemical modeling and chemical fate analysis. For constant physical properties first-order reaction, and dilute solutions in any media the CE in vector notation is
