For the past several years a metals forum has been established to review fom different areas associated with trace metals. The fom areas include (1) digestion and reference materials, (2) detection, instrumentation, and data handling, (3) soil analysis, metal availability, and plant uptake, and (4) regulation, enforcement, risk management, and education. 

The concentration of inorganic components in forage crops varies according to crop maturity, temperature, and soil pH and composition. The analyses of mineral content can reveal soil or management deficiencies as well as optimum harvest time for proper crop management. Actual mineral analyses are used to determine the amount of mineral supplementation to be added to an animal ration for proper nutritional balance. Reference methods of analysis include inductively coupled argon plasma (ICP), atomic absorption spectroscopy (AAS), and x-ray fluorescence spectroscopy (XRF). These techniques are well established for the analysis of mineral elements in whole-plant material. The exact procedures for sample preparation and analysis are well documented. Copies of the procedures may be obtained from instrument manufacturers or are readily found using basic texts for each analytical technique. 

The EPA Contract Laboratory Program (CLP) has responsibility for managing the analysis programs required under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The approved analytical methods are designed to analyze water, soil, and sediment from potentially hazardous waste sites to determine the presence or absence of certain environmentally harmful organic compounds. The methods described here all require the use of GC/MS.

Computers are well suited to the manipulation of numbers, but the ES relies on symbolic computation, in which symbols stand for properties, concepts, and relationships. The degree to which an ES can manage a task may depend on the complexity of the problem. For example, computer vision is an area of great interest within AI and many programs exist that can, without human assistance, use the output from a digital camera to extract information, such as the characters on a car number plate. However, automatic analysis of more complex images, such as a sample of soil viewed through a microscope, is far...

Benefit/cost analysis demonstrated that solarization can also be more convenient than other control techniques, due to its lower costs (Yaron et al. 1991 Elmore 1991a Bell 1998 Esperancini et al. 2003 Hasing et al. 2004). Potential integration of this technique within more complex pest management strategies is another main advantage of soil solarization, as they are technically combinable with most other available control methods. 

HasweU and Barclay [3] have described a microwave system coupled to an atomic absorption detection system for the analysis of sludges and soils. A major constraint at the present time is that the preferred operation of these types of systems is for sample matrices to be closely matched. A widely varying sample, which exhibits different heating characteristics, wiU either show up as an invaHd result or the time required to cope with this procedure for aU the samples wiU greatly extend the on-Hne analyses time scales. As more of these instrumental systems become Hnked to laboratory information management systems, it wiU become feasible to interact between the control database and the instrumentation so that each sample is treated in an appropriate manner and the optimum time frame is selected for each sample type. When new samples are analysed, the steps could be monitored so that the required time scales are obtained and then stored for future reference. 

The U.S. National Environmental Policy Act of 1969 required careful analysis of the consequences of any federally funded project. The Resource Conservation and Recovery Act (RCRA) of 1976 established guidelines for handling, transport, and hauling of hazardous materials, such as required in cleanup of soil contaminants. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 established, for the hrst time, strict mles on legal liability for soil contamination. CERCLA stimulated identihcation and cleanup of thousands of contaminated land sites, and consequently raised awareness of property buyers and sellers to make soil contamination a focal issue of land use and management practices (US-EPA 2007c).
