November 26, 1990 Update of Effects Screening Level List
Attached is the latest update of the list of the effects
screening levels (ESL's) currently used by the TACB Health
Effects staff in its evaluation of the impacts of various air
contaminants.
These screening levels are based on data
concerning health effects, odor nuisance potential, vegetation
effects, or corrosion effects. The ESL's on the list are based
on health effects unless followed by "(o)", "(v)", or "(c)" (for
odor nuisance, vegetation damage, or corrosion of materials).
Remember that these screening levels are just "tools" the Health Effects Section uses to evaluate the impacts of air pollutant emissions. They are not ambient air standards or guidelines. If predicted or measured airborne levels of a certain chemical do not exceed its screening level, we do not expect any adverse health or welfare effects. If ambient levels of air contaminants exceed the screening levels this does not necessarily mean there is a problem. It is just -an indication that further review will be required.
The table on the following page gives the effects screening levels which have been changed since the May 4, 1990 edition of this list. Some of these have been changed to reflect more accurate conversions from parts per billion to micrograms per cubic meter, some have been changed because of more recent data, and some have been changed to reflect changes in the Threshold Limit Values for 1990-1991.
If you cannot find a listing for a particular chemical, this does not medn that no health effects evaluation is required. Also note that these screening levels are subject to change without notice. To find out if a screening level has been established for a chemical or to be sure of the most current screening level, please check with the Health Effects staff.
