Exposure & Effects Pilot Study
(EEPS)

RMP Objective #4


Measure pollution exposure and effects on
selected parts of the Estuary ecosystem
(including humans)
EEPS Goals:
Develop a suite of indicators for S&T
 Conduct short-term studies to assess SF Bay
E&E

10-Year Program Review
Recommendations for EEPS (2003)
 Great chemical characterization of the
Bay but what does it mean?


Need to understand biological impacts of
chemicals detected
In response, TRC/SC allocated

$200K/yr for EEPS through 2008
Selection of Indicators

Rationale presented in Conceptual
Framework (2004) - ranked
Terns
 Cormorants
 Benthos/sediment
 Diving ducks
 Fish
 Clapper rails
 Seals

2008: Criteria for Inclusion
into Status & Trends

Relevance to Management Questions/Decisions


Scientifically achievable



Example: protection of endangered species,
evaluation of TMDLs, etc.
Example: Likelihood of finding significant effects or
documented effects in literature
Ability to represent overall health of Estuary
Mix of indicators
Proposed Research

Based on criteria, Four-year Plan proposes
continued research on:







Terns
Cormorants
Clapper rails
Diving ducks -anecdotal evidence suggests not a
policy concern?
Fish
Benthos/sediment
Seals - uncertainties regarding monitoring/hard to
establish E&E
Funded 2005

Fish Effects Study -AMS/UCD -- 2 yrs,
$50K per yr – high priority






Evaluation effects of contamination on shiner
surfperch (field and lab study)
Diving Ducks - $20K
Sediment Assessment - $15K
SFEI Labor - $25K
Peer Review - $5K
Total ~ $120K, remaining $80K
Proposed 2005





Terns - Hg analyses in Caspian, team w/USFWS
$3K
Benthos/Sediment Indicators - evaluation of
archive and scoping for 2006-2008 - $10K
Fish Effects - Add-on. Develop laboratory
culture - $20K
Clapper Rails - $5K scoping for exposure or
pathway study
Small Fish - $40K –PS -indicator of local
contamination and prey species (food web)
Proposed 2006 and beyond




Tern - Egg injection study
(PBDEs/Contaminant mixtures)
Benthos/Sediment Indicators – assess sed.
toxicity/benthic impairment, validation
of SQO work
Fish Effects - Continuation of 2005 work
Small Fish
Clapper Rail Effects
Cormorants Eggs - moving to S&T?
