40 Contaminant ph Phytotoxicity ph ph ph 5.0 to to to 6.5 >7.0 Arsenic 50 Cadmium 3 Chromium 400 Lead 300 Mercury 1 Nickel Copper Zinc The assessment concentration for lead is the Category 4 Screening Level produced by Contaminated Land: Applications in Real Environments (CL:AIRE) and outlined in Appendix H of their report SP1010. The others have been taken from Nathanail, C. P., McCaffrey, C., Gillett, A., Ogden, R., and Nathanail, J., 2015, The LQM/CIEH S4ULs for Human Health Risk Assessment, Land Quality Press, Nottingham. The metals/metalloids are based on a sandy loam soil and 6% soil organic matter. The assessment values are not intended to be applied to individual sample results where materials are similar, as the levels of contaminants will have a natural variability across the site. Instead, the modified mean value should be compared with the assessment concentration. The assessment values for phytotoxicity are the levels at which plant growth is thought to be affected. They are taken from the maximum permissible and advisable concentrations in soil after application of soil sludge given in the The Code of Good Agricultural Practice for the Protection of Soil, MAFF, The assessment of sulphate, water soluble sulphate, elemental sulphur and sulphide is to determine the aggressive nature of the ground with respect to concrete and consequently the results are compared with BRE Special Digest 1:2005 Concrete in Aggressive Ground.

P., McCaffrey, C., Gillett, A., Ogden, R., and Nathanail, J., 2015, The LQM/CIEH S4ULs for Human Health Risk Assessment, Land Quality Press, Nottingham. These are also all based on a sandy loam soil. Within the Environment Agency Science Report P5-080/TR3, Askari, K. & Pollard, S., 2005 The UK Approach for Evaluating Human Health Risks from Petroleum Hydrocarbons in Soils it is stated that the assessment values should not be considered individually; instead the potential additive effects should be calculated. This is achieved by calculating an individual Hazard Quotient (HQ) for each fraction. The HQ is the proportion of the assessment concentration represented by the recorded concentration. The HQs are then added together to form a Hazard Index (HI) and where this exceeds unity a potential significant risk to human health may exist.
