Description:

This introductory course provides participants with a strong foundation of aquatic toxicology and how these concepts are applied to managing pollutants in aquatic environments. The course covers terminology, common test designs, and endpoints such as lethality and endocrine disruption. Important legacy and emerging pollutants of concern such as heavy metals, organic pesticides, PAHs, PCBs, PBDEs, pharmaceuticals, personal care products, and nanoparticles will also be presented. Fate and transport as it relates to bioavailability and pollutant partitioning in aquatic environments will be discussed. Water Quality criteria from the Clean Water Act with an emphasis on, and examples of, site specific criteria for metals using hardness correction, water effects ratio (WER), and the biotic ligand model (BLM) are also included.

After completing this course, participants will be able to:

  • Apply toxicology principles to environmental issues.
  • Understand how aquatic organisms are exposed to toxic chemicals.
  • Identify factors affecting toxicity.
  • Understand similarities and differences between the toxicity of metals and organic chemicals.
  • Understand modes of action of toxic chemicals, types of effects from the molecular to the ecosystem level, and detoxification processes.
  • Assess toxicity in terms of LC50 and EC50, and develop dose-response curves.
  • Identify the advantages and disadvantages of various toxicity testing methods.
  • Understand the scientific basis for and limitations of water quality standards.

"Great overview and just the right amount of technical info." L. Hendriksen, February, 2013

"The course is an appropriate blend of new methods and technology with longstanding concepts and standards.  The approach of instruction engages attendees to use analytical tools introduced in problem solving then evaluates the value of the conclusion." B. Wanstall, April 2013

“[Instructor Ruth Sofield is] Very knowledgeable on broad scale and able to relate and convey information – able to relate on a “common” level, but also able to teach/discuss on Science/Chemistry/Biology.” T. Jackson, May 2013

*Reduced tuition is available for Native American tribes, government employees, nonprofits, students and AFS, NAEP, NEBC, TAEP members.

You may register online or by calling the Northwest Environmental Training Center at (425) 270-3274. Online registration is strongly encouraged.

Please wait to receive a course confirmation email, roughly one month prior to the class, before making any travel arrangements.

Intended Audience:

This course is designed for professionals seeking a greater understanding of aquatic toxicology and for practitioners and agency personnel, including toxicologists, biologists, ecologists, hydrologists, planners and regulators involved with stream issues.

Continuing Education Units: 1.30 CEUs

Prerequisites:

Some college-level biology and chemistry coursework is required (even if it was a long time ago). A fundamental understanding of aquatic ecology is also helpful.

Course Materials:

Attendees will receive a course manual containing workshop proceedings and reference material.

She has worked on projects that include: 1) genetically based tolerance to pollutant exposure in marine systems with the NOAA Ecotoxicology Branch, CCHEBR in Charleston, South Carolina, 2) development of groundwater WET tests with photoactive pollutants with the Washington State DOE, 3) understanding humic and fulvic acid interactions with Ag nanoparticles and the effects on chemical speciation and toxicity with Eawag in Dübendorf, Switzerland, and 4) metal contamination and effects in mining systems in Colorado, Idaho, Washington, and British Columbia with agencies including USGS and USEPA.

What to Bring

Please bring a pen or pencil, and notepad if you would like to take notes (you may also choose to take notes in your book). Lunch will be on your own, but drinks and snacks will be provided throughout the day.
