EPA draft ammonia assessment available for public comment
On June 1st the U.S Environmental Protection Agency (EPA) announced the release of its draft Integrated Risk Information System (IRIS) health assessment for ammonia. IRIS is a publicly available online database that that contains crucial information on more than 550 chemical substances and their impacts on human health. Governments and private entities use data from IRIS in conjunction with exposure information to help characterize the public health risks of chemical substances.
The draft assessment is available for public comment beginning June 8th for 60 days and will be sent for independent expert peer review. The draft assessment includes an estimate of the amount of ammonia a person can inhale daily throughout a lifetime that is not likely to cause harmful health effects, which is less stringent than the current value for ammonia on IRIS.
The draft uses a new streamlined document structure that identifies the strengths and weaknesses of analyzed studies and describes how EPA applied their guidance, methods, and criteria in developing the assessment. When the assessment is final it will be posted to the IRIS database.
