The purpose of characterizing soil (or other media) as suggested in this document is primarily to perform risk assessments with respect to human exposure. These assessments can be performed by referring to published international or national standards that set out physical, chemical or other criteria that shall be complied with, or according to criteria set on a site-specific basis. In many jurisdictions, formal guidance on such assessments has been published and should be considered. Guidance has also been provided by professional organizations and some standardization bodies. This document provides guidance on the types of information that might be required for a human health risk assessment and indicates for which parameters or procedures International Standards are available. The assessor should choose those parameters that are appropriate to the task at hand. The assessor will need to bear in mind the disproportionate costs and time delays that might result ifit is necessary to carry out an additional sampling campaign, or if, for example, a particular parameter is not determined when the opportunity is available. To provide context to this guidance, a general, non-normative account of human risk assessment, with particular emphasis on when humans are exposed to soil is provided in Clause 5. Clause 6 considers the relationship between soil and particular exposure pathways. Guidance on characterization of the soil,for example in terms of physical properties is provided in Clause 7 and in terms of what substances to look for and how to measure them in Clause 8. Clause 9 provides information on how the results of characterization can be used and Clause 10 provides guidance on how to ensure that information collected including analytical data are sufficient for the investigation in hand in terms of quality, quantity and type. How to achieve the last is the principal purpose of Clauses 7 and 8. This document refers in places to substance, potentially harmful substances (PHSs) and to contaminants. The latter applies strictly only when a substance or agent is present due to human activity but unless indicated otherwise or by the context can be assumed to also include substances that are present naturally as well as those present due to human activity. The term pollutant is not used in this document (see Note). BS ISO 15800 pdf download.
