The Known Unknowns: Emerging Chemical Contaminants in the Puget Sound and Beyond
AI summary Read the abstract
A presentation reviewed emerging chemical contaminants in Puget Sound including brominated flame retardants and microplastics, noting that risk assessments are severely limited by a lack of data on these relatively new pollutants. The talk highlighted gaps in knowledge that impede proper evaluation of environmental and health risks.
Baker will discuss the issue of emerging contaminants in Puget Sound, such as brominated flame retardants and microplastics. He will review the common features of the chemical classes studied, pointing out that risk assessment is limited by lack of information on these 'new' materials. He will also present several relevant studies.

Emerging Pollutants in the Environment
AI summary Read the abstract
This reprint details recent advances in understanding the occurrence, distribution, and environmental fate of emerging pollutants including microplastics, endocrine disruptors, pharmaceuticals, and persistent organic chemicals across air, water, soil, and food. The collection covers both risk assessment approaches and technologies for reducing and controlling these contaminants in the environment.
New brominated flame retardant decabromodiphenyl ethane (DBDPE) in water sediments: A review of contamination characteristics, exposure pathways, ecotoxicological effects and health risks
AI summary Read the abstract
This review examines DBDPE, a newer flame retardant chemical that is increasingly found in water sediments worldwide as it replaces older banned compounds. Evidence indicates that DBDPE concentrations are rising rapidly and the chemical poses ecological and health risks through bioaccumulation in aquatic food chains. The findings are relevant to microplastic research because flame retardants are common plastic additives that leach into the environment.
Emerging Food Contaminants
AI summary Read the abstract
This paper introduces the concept of emerging food contaminants as invisible chemical risks in modern food systems, reviewing how industrial chemical use has created new categories of food safety concerns including microplastics and persistent organic pollutants not covered by traditional regulations.
Occurrence, bioaccumulation, fate, and risk assessment of emerging pollutants in aquatic environments: A review
AI summary Read the abstract
This review summarizes research on five types of emerging pollutants in water, including microplastics, pharmaceuticals, fluorinated chemicals (PFAS), flame retardants, and disinfection byproducts. Wastewater treatment plants are the main source of these pollutants entering waterways, and microplastics along with PFAS and flame retardants can travel long distances and build up in living organisms. While ecological risk was generally assessed as low in most locations, the review highlights gaps in monitoring and the need for better prediction tools to protect water supplies and human health.
