CJJ/T 85 Standard for classification of urban green space
3 Terms and definitions
For the purposes of this standard, the following terms and definitions apply:
3.1
development land
land for construct buildings and structures, including urban and rural residential and public facilities land, industrial and mining land, transportation and water conservancy facilities land, tourism land, military facilities land
3.2
soil contamination risk of development land
adverse effects on health caused by long-term exposure of people living and working on development land to pollutants in soil due to chronic toxic effects or carcinogenic effects
3.3
exposure pathway
ways in which pollutants in the soil of development land migrate to reach and expose to human body and which mainly includes: (1) ingesting soil orally; (2) contacting with soil by skin; (3) inhaling soil particulate matter; (4) inhaling gaseous pollutants from topsoil in outdoor air; (5) inhaling gaseous pollutants from lower soil in outdoor air; and (6) inhaling gaseous pollutants from lower soil in indoor air
3.4
risk screening values for soil contamination of development land
under the specific land use mode, if the pollutant content in the soil of development land is equal to or lower than this value, the risk to human health may be ignored; if not, there may be risks to human health, and further detailed investigation and risk assessment shall be carried out to determine the specific pollution scope and risk level
3.5
risk intervention values for soil contamination of development land
under the specific land use mode, if the pollutant content in the soil of development land exceeds this value, there is usually unacceptable risk to human health, and risk control or remediation measures shall be taken
3.6
environmental background values of soil
statistical value based on the background content of soil environment, which is usually expressed by a percentile value of soil environmental background content, wherein soil environmental background content refers to the content of elements or compounds in soil under certain time conditions, which is only affected by geochemical processes and non-point source inputs
