Inventories of Pollutants

Taking into account that the pollutants mainly reach the Baltic Sea via atmospheric deposition and river discharge, afterward distributed in the Baltic waters by hydrodynamic

TABLE 14.6 Calculated Inventories of Anthropogenic Sourced Heavy Metals  

There are different patterns of distribution of the inventories of pollutants in the basins of the central and southwestern Baltic Sea, probably caused by the differences in the transport mechanisms and geochemical behavior of the components. However, most of the components show arelatively uniform distribution of the inventories (e.g., PCBs, Fig. 14.21). It means that the anthropogenic amount of these contaminants deposited in the basins varies only in narrow ranges. Independent of the location of possible sources, these contaminants were widespread and distributed over the whole area before deposition. 

Another example is Pb, which is known for very strong particle-bound deposition, and the near coastal and shallower western Baltic basins contain nearly equal inventories of 2 g/m , and this is four times more than the amount of the far and deep central Baltic Sea basins (see Fig. 14.22). For Hg, the Arkona Basin and the Gdansk Basin show higher amounts than all other basins, which are comparable with values between 1 and 2.3 mg/m. DDTs and Cu, for example, vary in larger ranges without clear regional relationships.

Hphe present inventory of pollution abatement sulfur is increasing by about 4 million tons per year, and by 1980 the supply could begin to exceed the demand (1). On the basis of this outlook, industry, government, and university groups have initiated a considerable amount of research and development to develop new uses for sulfur. 

Environment Canada (2009) has 14 metal substances regulated under the National Pollutant Release Inventory (NPRI) (Table 7.3). The NPRI is Canada s legislated, publicly accessible inventory of pollutant releases (to air, water, and land), disposals, and transfers for recycling (Environment Canada 2009). 

An emission inventory is a list of the amount of pollutants from all sources entering the air in a given time period. The boundaries of the area are fixed (8).

Valid emission factors for each source of pollution are the key to the emission inventory. It is not uncommon to find emission factors differing by 50%, depending on the researcher, variables at the time of emission measurement, etc. Since it is possible to reduce the estimating errors in the... 

Pollutant concentration maps may be constructed as shown in Fig. 15-5 (14). In this example, elevated levels of ambient particulate matter are associated with population centers. For a given geographic area, isopleths, lines showing equal concentrations of a pollutant, are drawn on a map. Regions of high concentration are quickly identified. Further action may be taken to determine the cause, such as review of emission inventories of additional sampling. 

The emission inventory and the initial and boundary conditions of pollutant concentrations have a large impact on the ozone concentrations calculated by photochemical models. 

Emissions and inventories are in the case of air pollution related to the assessment of the level of pollutants released from various sources. That is to say emission specification of the relevant technologies and pollutants. The determination of emission factors of different substance in WEEE road transport is often the product of national, EU and international research. 

Therefore data on anthropogenic and natural emissions in the Asian region are necessary for the assessment of heavy metal pollution in these countries. Pollution of Kazakhstan and Kyrgyzstan by mercury and lead has been initially assessed by means of hemispheric modeling using the available global emission inventories of the considered heavy metals. The outcomes of the assessment are presented in this section. 

This brief overview of separate treatment techniques is not complete, however it can be used for a first inventory and identification of treatment steps which may be considered as part of a complete closed loop water system. It has to be taken in mind that the above-mentioned overview of separate treatment techniques is primarily based on one type of pollutant and one physical state of that pollutant. It will be clear that very often the same treatment step can be applied to remove different types of pollutants. It is also evident that a large percentage of the separate treatment steps mentioned will result in a concentrate containing the pollutants. This concentrate has to be treated subsequently. 

The starting point in the development and designing of a closed water loop system is an inventory of the amounts and the quality of the process and transport water flows which are needed for the various steps in the production process. Each production step where process or transport water is involved causes a certain amount of wastewater. The pollution of this water is strongly dependent on the process step. The selection of separate treatment steps which, together, comprise a closed loop water system is complex. As already mentioned, various complete treatment scenarios can be developed and designed to satisfy the requirements set for process and transport water and treatment of wastewater. A technical and economic evaluation, in combination with environmental sustainability assessment, is necessary to determine the treatment system which is most appropriate.

One of the central problems in air pollution research and control is to determine the quantitative relationship between ambient air quality and emission of pollutants from sources. Effective strategies to control pollutants can not be devised without this information. This question has been mainly addressed in the past with source-oriented techniques such as emission inventories and predictive diffusion models with which one traces pollutants from source to receptor. More recently, much effort has been directed toward developing receptor-oriented models that start with the receptor and reconstruct the source contributions. As is the case with much of air pollutant research, improvements in pollutant chemical analysis techniques have greatly enhanced the results of receptor modeling.
