Chemistry and environmental research

What we see is that all disciplines overlap. The original focus of geology as the science of the (solid) earth, hydrology as the science of liquid water, and meteorology as the science of the atmosphere, is still valid and should not be diffused, but the modern study of earth sciences looks at the planet as a large, complex network of physical, chemical, and biological interactions (Sammonds and Thompson 2007). This is known as a systems approach to the study of the earth. The systems approach treats the earth as a combination of several subsystems, each of which can be viewed individually or in concert with the others. These subsystems are the geosphere, the atmosphere, the hydrosphere, and the biosphere. 

As mentioned in the preface, this book will treat the chemistry of the climate system according to the elements and its compounds depending from the conditions of reactions and whether the substance exists in the gaseous or condensed (aqueous and solid) phase. Not yet discussing how we should understand a climate system (see Chapter 3.2), we will initially set it in a chain of subsystems  

In other words, each system to be defined lies in another mother system, the surrounding or environment where an exchange of energy and material is realized via the interfaces. Consequently there is no fully closed system in our world. 

As shown above, the climate system is a subsystem of the earth system. The chemistry of the earth system - when not considering life - is geochemistry. The term geochemistry, hke many other scientific terms, has variable connotations. If geochemistry means simply the chemical study of the earth or parts of the earth, then geochemistry must be as old as chemistry itself, and dates from the attempts of Babylonian and Egyptian metal-workers and potters to understand the nature and properties of their materials (Tomkeiev 1944). 

The chemical composition of air depends on the natural and man-made sources of the constituents (their distribution and source strength in time and space) as well the physical (e. g. radiation, temperature, humidity, wind) and chemical conditions (other trace species) which determine transportation and transformation. Thus, atmospheric chemistry is not a pure chemistry and also includes other disciplines which are important for describing the interaction between atmosphere and other surrounding reservoirs (biosphere, hydrosphere, etc.). Measurements of chemical and physical parameters in air will always contain a geographical component, i. e., the particularities of the locality. That is why the terms chemical weather and chemical climate have been introduced. For example, diurnal variation of the concentration of a substance may occur for different reasons. Therefore general conclusions or transfer of results to other sites should be done with care. On the other hand, it is a basic task in atmospheric chemistry not only to present local results of chemical composition and its variation in time, but also to find general relationships between pollutants and their behavior under different conditions.

Based upon laboratory and mini- or pilot-plant experiments process flow-sheets are prepared that also take environmental and safety aspects into consideration. Studies on these aspects are carried out in parallel with chemistry and engineering research in the form of so-called Integrated Process Development (see Heinzle and Hungerbiihler, 1997). 

The analysis of environmental TPs has become a major trend in environmental chemistry, and increasingly, researchers are taking this a step further in proposing complex transformation pathways. It is expected to see a gradual shift from parent compound analysis to the analysis of metabolites and TPs. It is evident that more research is needed to determine the breakdown pathways and to evaluate the fate of TPs. Therefore, development of future generic analytical protocols should permit the simultaneous determination of parent compounds and their metabolites.

There are other areas of chemistry in addition to the traditional four mentioned above, such as biological chemistry and environmental chemistry, which are basically still untouched by positron and Ps researchers. They are not covered in this book since significant results in these two areas have been presented in our previous book [11].
