4 Use of this document
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 he 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 if it 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 1, 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 .
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).
As indicated by the note below, those preparing human health risk assessments should always be careful to define the terms and concepts they are employing in reports. Terms are not used consistently by people with different backgrounds and experience, and there can be subtle differences in how terms are used and understood. It is also important to remember that reports will often be read by those without specific training or education in risk assessment.
NOTE It is important when carrying out human health risk assessment to carefully define the terms that are being used, especially for example contaminant/contaminatlon and ‘pollutant/pollution because they might not be understood to have the same meaning by people with different backgrounds and experience. This document follows the established convention for documents published by ISO Technical Committee 190 (TC19O) in distinguishing between “contaminant (substance or agent present in an environmental medium as a result of human activity — see i4) and ‘poIlutant” (substance or agent present in the soil (or groundwater) which, due to its properties, amount or concentration, causes adverse impacts on soil functions – see i14 and ISO 11074:2015, 3.4.18). Hence, contamination and pollution” are not considered to be the same thing. However, it is recognised that this distinction is not always made at official level in all jurisdictions. Even In those jurisdictions where it is recognised, it might be for some purposes but not others and the definitions of contamination and pollution” used in legislation and regulations for different purposes can differ. In addition, the use of the terms is not necessarily consistent between and even within guidance documents produced by government and professional bodies.
S Background
5.1 Characterization of soil and sites with respect to human exposure
Characterizations of soils and sites with respect to human exposure are usually performed as a part of a risk assessment.
In most countries, industrial activities have had adverse effects on soil and groundwater quality.
Similarly, soil and groundwater quality is often adversely affected by agricultural and similar activities.
Elevated concentrations of potentially harmful substances (PHSs) can also be present naturally.
The accumulation of substances In soil, groundwater and other media (food, air) should be taken into account when quantifying human exposure to PHSs to assess potential effects on humans.
PHSs often have acute and/or chronic effects on human health. The risks usually addressed in formal human health risk assessments (for example, of old industrial Sites) are chronic.
In the event of an incidental discovery of contamination during excavation, potential effects on, for example, human health and safety, should be identified, measured and monitored, and assessed
The toxic action of a substance can be divided into acute effects and chronic effects:
— acute health effects are quickly seen, usually after exposures to fairly high levels or concentrations of potentially harmful substances (such exposures often cause severe symptoms in animals or humans which develop rapidly).BS ISO 15800 pdf download.
