Pollution inventory

The basie database for the eontrol of environmental pollution is a pollution inventory, viz. a tabulation of emissions, diseharges and wastes from the faetory or aetivity eovering all operating phases. This ineludes ... 

In previous studies we found that improved emission-control devices (such as hot-side electrostatic precipitaters and wet-scrubber systems) now being installed on modern pulverized-coal-fired power plants modify the quantity, chemical composition, and distribution characteristics of fine aerosol emissions (12,13). Such modifications must be understood to adequately assess human health and environmental hazards, and to apportion the contributions of sources to urban pollutant inventories. 

In general, we feel that there are far too few studies of the composition of particles in the submicrometer region. More studies are needed to adequately characterize the human health and environmental hazards associated with utility coal combustion, and to more accurately determine their contribution to urban pollutant inventories. 

Many other countries operate pollution inventories, such as Austria, Canada, Denmark, Netherlands, France, Germany, Hungary, Mexico, Norway, Scotland, Spain, and Sweden. The policies do tend to differ slightly from one another. In particular, the substances requiring reporting and their associated thresholds can vary significantly. Unfortunately, not all the countries operate this kind of inventories thus the amount of toxics released around the world remains unknown.

The foregoing discussion has, for the most part, looked at fully developed PRTRs within a fairly strict context as defined by the OECD and various international conventions. It should be noted that a larger array of countries have in place pollution inventories or a PRTR under development or consideration. Among these are all European Union Member States, Brazil, Bulgaria, Chile, Croatia, Cuba, Egypt, Kazakhstan, Moldova, Romania, Russia, South Africa, Switzerland, and Thailand. These countries, and many others, may or may not ultimately adhere to the requirements set up for a full-scale PRTR, but their efforts to report to the public on pollution are clearly in the right direction. 

The pollutant inventory obtained gives an overview of the total current emission picture for the study area. Table 3.1 presents this data for Los Angeles, where the inventory was conducted to assist in determining the causes of the photochemical smog problem. For comparison, parallel data are presented for the whole of Canada which also has smog problems in some of the major centers. A more recent inventory conducted for Madrid displays a similar picture [4]. The best foundation for effective planning of abatement measures is obtained from inventories of this kind, aided by continual refinement of the information [5, 6].

Hydrocarbon vapor losses from refineries are about 5-10% of the total hydrocarbons discharged to the atmosphere, from pollutant inventories [55]. However, refinery losses are highly localized so that control is important to minimize local ambient air concentrations of hydrocarbons. Any volatile sulfides require more stringent monitoring and control measures because of their toxicity and very low odor thresholds. 

Reporting on emissions for regulated processes through the Pollution Inventory. 

Ways, other than legislative means, in which control can be exerted are also shown in Figure 9.2. These include codes of good practice and campaigns, fiscal measures such as the landfill tax and the proposed pesticide tax, and the publication of information. The Environment Agency s Pollution Inventory, launched in 1999, provides environmental information to a large audience, particularly the general public. The inventory is a database of emissions of pollutants to the environment from particular industries in the UK.

Figure 1, shows an edited version of the pollution inventory for the process. This data is accessible on the net. The data represents the number of Kg of each pollutant released over the course of the specific year for which the data was reported. The conclusion drawn is that this raw data conveys little about the environmental significance of the process.

Data for three aspects of sustainability are gathered for a period of 8 years, fix)m 2006 to 2014, from the Ecoinvent database, social hotspot database, feasibility reports of the power plant, and other types of literature. Because both of these power plants are not currendy operating, their emissions are approximately calculated on the basis of the National Pollutant Inventory Emission estimation technique, developed in Australia. Relevant details of data quahty and data sources can be found in Table 14.5 and explained in the section Inventory Analysis. 

Data for the reference system—coal-fired electricity—are adapted from Loi et al. s study [46], the Ecoinvent database for rest of world (RoW) [47], technical reports of PECCI [42], and GIZ-GDE/MOIT s report [48], in combination with calculation results following the guidelines of the AustraHan National Greenhouse Accounts and the National Pollutant Inventory Emission estimation technique manual for Fossil Fuel Electric Power Generation [49,50]. Fig. 14.3 illustrates different processes of generating coal-fired electricity.

Operators have to monitor their emissions and report them to the Environment Agency on a yearly basis. Information on levels of pollution released from individual IPC processes is available from the Environment Agency s Pollution Inventory.
