Notes:
It is noted that at elevated copper and zinc concentrations, phytotoxicity might start to limit vegetable growth and may become a major cause of concern. In these
circumstances the ICRCL limit of 130 mg/kg for copper, and the ICRCL Tentative ‘Trigger concentration’ of 300 mg/kg for zinc might need to be considered as suitable generic
assessment criterias in order to be protective of plant growth.

Notes:
The soil remediation Intervention Values indicate when the functional properties of the soil for humans, plant and animal life, is seriously impaired or threatened. They are
representative of the level of contamination above which there is a serious case of soil contamination (Dutch Circular). Values for soil/sediment have been expressed as the
concentration in a standard soil assumed to be 10% organic matter and 25 % clay.

Human Health Generic Screening Values for Soils
CIEH/LQM GAC Values
Generic Assessment Criteria (GAC) Values for Human Health Risk Assessment were derived by the Chartered Institute of Environmental Health (CIEH) and Land Quality
Management Ltd. (LQM) during a workshop at the University of Nottingham held in July 2006, and are presented in the following tables. This document is hereafter referred to
as the GAC Manual.
The GAC are intended to be ‘intervention values’ that ‘mark the concentration of a substance in soil at or below which human exposure can be considered to represent a
‘tolerable’ (where the relevant health criteria value is a tolerable daily intake) or ‘minimal’ (where the health criteria is an index dose) level of risk and that ‘exceedance can
indicate to an assessor that further assessment or remedial action may be needed. (At the same time, non-exceedance will indicate that risk is acceptable and that land is
suitable for its use, with regard to the contamination in question)’ (DEFRA 2005, within the GAC manual).
The GAC values are broadly equivalent to the Soil Guideline Values published by DEFRA and the EA between 2002 and 2004. They do not have the same status of SGVs
simply by reason of their origin. They will be redundant as and when DEFRA and the EA publish a SGV for a substance. A local authority may choose to adopt these values
for use within their area.
Non exceedance of a relevant GAC indicates that the soil contaminant levels are such as not to compromise human health.
Exceedance of a relevant GAC value does not constitute evidence of a significant possibility of significant harm. Rather such exceedance should trigger a further detailed
quantitative risk assessment where site-specific parameters are used to derive site-specific assessment criteria. Where Delta-Simons has conducted such a site-specific risk
assessment, the physical, chemical and toxicological input parameters taken have been the same as those used by the CIEH and LQM, and are detailed in the relevant tables
below.
The GAC were calculated using the Environment Agency’s CLEA UK Software Beta Version 1.0 (2006), using the generic simulation model of the model. Input parameters
were drawn either from Environment Agency documents or from other reliable sources of information in accordance with relevant guidance from the EA.
The GAC presented below are those based on a SOM content of 1% by weight, which is considered to be the most conservative scenario of those modelled by LQM/CIEH.
The Assessment Sub Criteria (ASC) for the sTPHs were calculated using a SOM of 2.5%, but the Cumulative value is for 1% SOM.
N/A indicates that this pathway is not included in the conceptual model for the standard land use.
Further information is available in the DEFRA publications CLAN 6/06, CLAN 4/06 and CLAN 2/05.

Notes:
For the inorganic chemicals such as the metals, soil/water partition coefficient (Kd) is utilised to calculate distribution between different environmental media. For organic
chemicals it is estimated in the software from Koc and foc. For Kd values utilised, please refer to the GAC handbook.
For several of the parameters the value has been derived by LQM and CIEH from the sources above. For details, please refer to the GAC manual.
The Dust Enrichment Factor is ‘Yes’ for the metals and the PAH, in accordance with information from the EA 2003 and CLR10, as provided in the GAC handbook.

Delta-Simons HH-GSVs
The following tables provide Human Health Generic Screening Values (HH-GSV) for selected contaminants for which no SGV or GAC exists. The aim was to derive a wider
data set of generic screening values that could be used in coordination with CLEA GACs, as they were calculated in a similar manner. HH-GSVs are provided for three
different generic end uses, these are commercial/industrial, residential with plant uptake and residential without plant uptake. The toxicity data and physical chemical
parameters for the contaminants of concern (CoC) are also provided. These HH-GSVs were calculated using the CLEA UK Software Beta Version 1.0., and if exceeded may
be indicative of unacceptable risks to human health from chronic exposure to contaminants, and that a Site-Specific Risk Assessment may be necessary. The HH-GSVs are
based on a set of conservative parameters to produce values considered appropriate for an initial screening process and below which remediation is not considered to be
necessary with respect to human health.
The HH-GSVs take into account a cumulative effect of all the potential pathways for the particular generic land use ensuring a conservative approach.
The assessment sub criterion (ASC) were calculated using Equation 1-1 from Section 1.7 of the GAC Manual.
Delta-Simons considers that these HH-GSVs have been calculated using appropriate toxicological data that is currently available but will be updated as and when any new
CLEA Tox Reports are published for the CoC. The HH-GSVs are not regulatory approved but are considered to represent suitably conservative values for an initial screening
process which is protective of human health.
The Delta-Simons HH-GSVs have been derived in the Generic Assessment mode of the CLEA UK Beta Model, based on a sandy soil with a soil organic matter content of 1 %
and pH of 7.0.
The solubility values used were generally measured between 10 ºC and 25ºC, for example the solubility given for benzene in EA2003 is quoted at 20 ºC, which is not
considered to represent a standard temperature for UK soils. Following the example of the CIEH and LQM in deriving the GAC values, it is assumed that the solubilities will not
vary significantly between the two temperatures.
The CLEA Beta model requires the vapour pressure at 10 ºC to be entered. Following the example of the CIEH and LQM in deriving the GAC values, the vapour pressure
values have been corrected to 10ºC. This has been done using the Clausius-Clapeyron Equation within a spreadsheet written by Delta-Simons.
The CLEA Beta model requires the Henry’s Law Constant and the reference temperature to be input, therefore it was not necessary to manually correct the Henry’s Law
Constant to 10ºC.
The Default value of 0.1 for the dermal absorption fraction is chosen, as given in Table 1 of CLEA Briefing Note 1.
When researching the physical and chemical input parameters, Delta-Simons has followed the hierarchy of source documents detailed in Section 1.5 of the GAC Manual.
A hierarchy of sources for the TDI data was employed; firstly DEFRA/EA Tox reports, then DUTCH MPR (maximum Permissible Risk) information, then WHO/EHC data,
USEPA IRIS information and USEPA PRG Region 9 information. For references, see below.

Note: For Phenol the inhalation pathway could not be split, as health criteria for the inhalation and dermal routes for phenol cannot be derived until reliable animal or human data becomes available
(TOX 9, DEFRA/EA). Phenol is within the CLEA UK Beta default library data set but there is no inhalation TDI value.

Notes
Calc. In order to be conservative, the MDI has been calculated as 80% of the TDI, assuming an average adult body weight of 68.5 kg.
NAQIA – Inhalation MDI calculated from the National UK Air Quality Information Archive data from the highest UK annual mean air concentration for 2005, assuming an adult
3
inhales 20 m per day.
For MTBE, the TDI Oral of 0.09 mg/kg bw./day has been calculated by Delta-Simons based on the NOAEL for rats of 90 mg/kg bw./day given by WHO (1998) in the EHC
document for MTBE, assuming an uncertainty factor of 1000 (100 for inter-and intra-species variation and 10 for limited data). The TDI inhal of 0.857 mg/kg bw./day has been
calculated by Delta-Simons based on the IRIS RfC inhal of 3 mg/m3 , and Equation 1.0 detailed below.
For MEK, the TDI Oral is taken from the RfD oral of 0.6 mg/kg bw. Given in EPA Toxicological Review of MEK, Sept 03 (EPA 635/R-03/009). This was calculated from data for
rats exposed to 2-butanol (proxy for MEK). The TDI inhal has been calculated by Delta-Simons based on the EPA RfC inhal of 5 mg/m3 using Equation 1.0.
Within the DUTCH reference, CRoral and CRinhal refer to health criteria for non-threshold substances for oral and inhalation routes respectively, and have been assumed by
Delta-Simons to be the equivalent of the TDI Oral and TDI ihal. Some information on Dutch terminology is given in CLR9 A13.

USEPA Definitions for Reference Dose and Reference Concentration
Reference Concentration (RfC): Definition applied prior to July 2005: An estimate (with uncertainty spanning perhaps an order of magnitude) of a continuous inhalation
exposure to the human population (including sensitive subgroups) that is likely to be without an appreciable risk of deleterious effects during a lifetime. It can be derived from a
NOAEL, LOAEL, or benchmark concentration, with uncertainty factors generally applied to reflect limitations of the data used. Generally used in EPA's noncancer health
assessments.
Revised definition - effective July 2005: An estimate of a continuous inhalation exposure for a given duration to the human population (including susceptible subgroups) that is
likely to be without an appreciable risk of adverse health effects over a lifetime. It is derived from a BMCL, a NOAEL, a LOAEL, or another suitable point of departure, with
uncertainty/variability factors applied to reflect limitations of the data used. [Durations include acute, short-term, subchronic, and chronic and are defined individually in this
glossary].
Reference Dose (RfD): Definition applied prior to July 2005: An estimate (with uncertainty spanning perhaps an order of magnitude) of a daily oral exposure to the human
population (including sensitive subgroups) that is likely to be without an appreciable risk of deleterious effects during a lifetime. It can be derived from a NOAEL, LOAEL, or
benchmark dose, with uncertainty factors generally applied to reflect limitations of the data used. Generally used in EPA's noncancer health assessments.
Revised definition - effective July 2005: An estimate of a daily oral exposure for a given duration to the human population (including susceptible subgroups) that is likely to be
without an appreciable risk of adverse health effects over a lifetime. It is derived from a BMDL, a NOAEL, a LOAEL, or another suitable point of departure, with
uncertainty/variability factors applied to reflect limitations of the data used. [Durations include acute, short-term, subchronic, and chronic and are defined individually in this
glossary].
To calculate the inhalation reference dose (RfDi) from the inhalation reference concentration (RfC), the following equation has been used;
RfDi (mg/kg bw./day) = RfC (mg/m3) x 20 m3/day x 1/70 kg
(Equation 1.0)

“>” indicates that the HH-GSV exceeds the constituent solubility value (groundwater). The predicted volatilisation within RBCA model is carried out using the Johnson and Ettinger equation, which is
only valid for dissolved phase concentrations of contaminants. Where the HH-GSV is indicated to exceed the constituent solubility value, this means that even if free product were encountered it
would not cause adverse effects via that particular exposure pathway, (this is confirmed by the Fact Sheet for the RBCA Tool Kit for Chemical Releases by the Environment Agency, FS-02,
February 2003).
NC - HH-GSVs for the heavy end aliphatic and aromatic hydrocarbons in the range >C16-C35, for some of the Pah’s, PCBs and dioxins are not calculated by the RBCA method. Given the low
volatility, there is also no inhalation reference concentration within the RBCA Toolkit for these compounds and they are not considered to be of concern via the inhalation exposure pathway. HHGSVs for the dichloroethenes are not calculated as no inhalation reference dose has been sourced to date.
Carcinogenicity data from RBCA, DEFRA, USEPA and IARC.
The HH-GSVs are based upon the indoor inhalation pathway in order to maintain a conservative approach.
Constituents of Concern Input Parameters
The Constituents of Concern input parameters have been updated from the default values within RBCA, in order to reflect the CLEA
methodology. Where possible, toxicological information was taken from the DEFRA TOX reports.
For carcinogenic compounds, the Oral Index dose (ID oral) from the DEFRA TOX reports was input into the model as the Oral Reference Dose
(RfD oral). The inhalation Index Dose (ID inhal) was also input into the model, as the Inhalation Reference Concentration (RfC inhal). In order
to convert the ID inhal to the correct units, it was necessary to perform the following calculation;
Inhalation Index Dose (mg/kg/day) x Average Weight (kg) / Average Inhaled Concentration per day (m3/day) = Value input (mg/m3)
i.e. Value input = ID inhal x (70/20)
The Average Weight of 70 kg was taken from CLR 9 Para. 3.19.
The Average inhaled concentration of 20 m3/day was taken from CLR 9 Table 3.1.
For non-Carcinogenic compounds for which there is a DEFRA TOX report, the Oral Tolerable Daily Soil Intake (TDSI) and Inhalation TDSI
could be input into the model in place of the RfD oral and the RfC inhal, respectively.
For non-carcinogenic compounds for which there is no DEFRA TOX report, the Oral and Inhalation TDSIs were calculated from the RBCA RfD
oral (TDI equivalent) and RfC inhal (TDI equivalent), with consideration of the Mean Daily Intake (MDI), as detailed in CLR 9 Para. 3.26.

Human Health Groundwater Generic Screening
Values Derived Using RBCA.
___________________________________________________________________________________________________________________________________________
In summary:
Where the MDI < 80% TDI, then the TDSI = TDI - MDI
Where the MDI ≥ 80% TDI or if the MDI was unknown, then the TDSI = 0.2 x TDI
The Henry’s Law Concentration was corrected for an average annual temperature of 10 ºC, on the basis that the ambient soil temperature at
UK sites is 283 K from CLEA Briefing Note 2 Version 1.1, Table 3. The correction was performed using the USEPA on-line Tools for Site
Assessment Calculations http://www.epa.gov/athens/learn2model/part-two/onsite/esthenry.htm. The calculation was performed for benzene,
toluene, ethylbenzene, xylenes (as o-xylene), naphthalene, vinyl chloride, 1,1,1-trichloroethane, 1,2-Dichloroethane, aromatic C5-C7 (as
benzene), aromatics >C7-C8 (as toluene), chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, dibenzo(a,h)anthracene,
