Information for Various Types of Non-ATSDR Screening Levels

There are various types of non-ATSDR screening levels; this table lists some. Note that ATSDR does not endorse the use of any non-ATSDR screening level, but this list includes sources suggested by health assessors for various types of non-ATSDR screening levels. Many available non-ATSDR screening levels are based on health effects observed in scientific studies, but others are not completely health-based. Health assessors should choose non-ATSDR screening levels that are most protective of the potentially exposed population, and are most akin to ATSDR’s health-based CVs. Before using non-ATSDR screening levels in your analysis, ensure you understand how the non-ATSDR screening levels were derived and discuss their possible use with the Associate Director for Science (ADS) group.
