Description

Proper environmental stewardship of products necessitates an understanding of materials in use and potential impacts to humans and wildlife from environmental releases. However, there are limits to resources that may be devoted to such efforts. The trick is in knowing how much is enough.

A tiered risk assessment methodology uses an iterative approach of increasingly sophisticated investigation for those instances where the substance assessment requires additional information. In this session, we will discuss the tiered assessment paradigm as it applies to environmental hazards and exposures, and present methods and models used to refine our understanding of potential risk. For example, environmental releases can occur during various stages of a product's life-cycle such as manufacture, use and disposal. Screening and higher-tier exposure and fate models used to predict environmental concentrations will be discussed.

Likewise, the spectrum of hazard data acquisition will be explored from use of existing data directly or through read-across, computational methods, laboratory investigations, and field studies. Case studies will be presented illustrating real-world application of these methods across diverse chemistries and products.

Learning Objectives

By the end of this session, attendees will:

• Explain the concept and advantages of a tiered risk assessment paradigm
• Summarize environmental fate and exposure models
• Discover sources for acquisition of hazard data and information
• Apply available higher-tier approaches to utilize if needed
• Construct a tiered approach in prioritizing a large chemical pallet and better manage resources
