iSTREEM – A “down-the-drain” environmental exposure model for the United States
The American Cleaning Institute (ACI) serves the growth and innovation of the U.S. cleaning products industry by advancing the health and quality of life of people and protecting our planet. With a continued effort in promoting public health and safety, its experts have developed iSTREEM®, an in-stream environmental exposure model, which predicts the concentration of a chemical used in “down-the-drain” products. It is a tool to promote product stewardship and regulatory compliance for chemical suppliers and manufacturers of formulated products of all sizes across commodity groups.
iSTREEM® (In-STREam Exposure Model) is a web-based model (https://www.istreem.org/) designed to estimate the concentrations of down-the-drain (DtD) chemicals in the surface waters of the continental United States. Based on the best publicly available data, the model focuses on the use and disposal of items ranging from personal care and home care products to food additives, pharmaceuticals, and home use pesticides.
iSTREEM® is a spatially explicit model with broad scale capability and enables assessments of chemicals in high volume products across a large geography. The models results also provide a probabilistic distribution of predicted environmental concentrations (PEC) in surface waters across the U.S.
ACI partnered with researchers at Procter & Gamble during the early 2000s to elevate the iSTREEM model from the computer-based program it once was into the web-based model we have today. ... ...
