This chapter provides orientation and an introduction to the subject of air quality. As a part of this introduction, we begin exploring the options for ensuring high quality air in the environment. The focus of this book is on industrial air pollution problems, and hence, the term environment refers to the universal ecosystem that humans live and interact in, as well as the workplace.

In vitro In an artificial environment, referring to a process or reaction occurring therein, as in a test tube or culture media. 

Reference values are intended to characterize the upper margin of a current background contamination of a pollutant at a given time. For contaminants in the indoor environment reference values may be calculated applying the procedure as for environmental toxins in body fluids (Ewers et al., 1999). Reference values for pollutants in house dust were reviewed recently by Butte (2003). It has to be emphasized that a reference value has no health meaning nor regulatory implication. 

Notes B1 = survey on the actual condition of chemical substances in the environment (until 2001) B2 = survey on the actual condition of chemical substances in the environment (after 2002) D = survey under the Law concerning Special Measures against Dioxins E = survey on the environmental endocrine disrupters W = survey under the Water Pollution Control Law A = the air pollutants monitoring O = other survey. Details of the survey on the actual condition of chemical substances in the environment refer to Ministry of the Environment web site http // www.env.go.jp/chemi/kurchen/index.html (also refer to annual reports before FY1996). 

In the case of ET AAS, it is the far superior simultaneous BC and the visibility of the spectral environment (refer to Section 4.3.3) that dramatically contributes to an overall simplification of the procedure and to an increase in accuracy of the analysis. All things that are visible are much easier to understand and control than things that remain in the dark, as is the case with LS AAS. This is particularly true for all kinds of spectral events that might result in interference, although this risk is significantly reduced in HR-CS AAS thanks to the high resolution of the spectrometer.

DATALOG was developed through the collaborative efforts of EPA s Office of Toxic Substances and the Syracuse Research Corporation (SRC). It includes bibliographic references to published journal articles on the environmental fate and physical-chemical properties of chemicals released into the environment. References to 18 environmental fate properties (e.g., water solubility, photolysis, hydrolysis, biodegradation, and more) are included for more than 16000 chemical substances in over 320000 records.

The chemistry of seawater is only one aspect of a marine environment. Substrates also play important roles because they serve as homes to many organisms. The substrate of a marine environment refers to the material that makes up the bottom or floor of the area, and it can be one of three types loose and sandy, muddy and compact, or hard and rocky.

Photochemical reductions and oxidations in aquatic environments provide sinks or sources for halocarbons. Such photoreactions are an important process in the dissipation of low-volatility halocarbons, such as halogenated agrochemicals, in aquatic environments (reference 9 contains lead references). For example, field studies of Crossland and Wolff (10) demonstrated the rapid dissipation of pentachlorophenol residues by its photoreaction in English ponds. Evidence emerged that volatile halocarbons such as 1,1,1-trichloroethane (methylchloroform) may have significant sinks in the aquatic environment... 

There are two important components of the environment in which societies exist. The physical environment (topography, climate, water, vegetation, soil, rocks, and minerals) provides the necessary resources and conditions for human society. The cultural environment refers to the humanly created environment, as well as relationships with other human groups in the physical environment.
