CURRENT ISSUES
  • Increasing range of pollutants
  • Multiple mechanisms of toxicity
  • Complex coastal ecosystems
  • Diverse array of analytical and diagnostic tools
  • Limited public funds

3
ECOMAN - PROJECT AIMS
  • To develop more pragmatic environmental
  • assessment techniques linking environmental
  • degradation with its causes
  • To apply a weight-of-evidence approach to
  • their use in ecosystem management

4
BIOMARKER A DEFINITION
  • Functional measures of exposure to stressors
    expressed at the sub-organismal, physiological or
    behavioural level
  • (McCarthy and Munkittrick, 1996)
  • Surrogate measures of organism health and
    chemical impact

5
Response Time
Ecological Relevance
6
SAMPLING STRATEGY
  • Defined by ecosystem hierarchy
  • Considers trophic level of sentinel organisms

7
COMMON COASTAL ORGANISMS WITH DIFFERENT FEEDING
TYPES
Halichondria panicea
Asterina gibbosa
omnivorous scavenger
filter feeder
Nereis diversicolor
Nucella lapillus
omnivore
carnivore
8
AIM
  • To conduct a rapid assessment of marine pollution
    in coastal sites of the UK using the ECOMAN
    approach

Background information
Biological effects general health lysosomal
stability cardiac output immunocompetence
Chemical analysis PAHs metals biocides
Types of exposure hydrocarbons - PAH
fluorescence metals - metallothionein genotoxins
- micronucleus endocrine disruptors - imposex,

HOW CAN THESE DIAGNOSTIC TOOLS BE USED TO REFLECT
ENVIRONMENTAL QUALITY?

MULTIVARIATE STATISTICAL ANALYSIS
  • Univariate analysis describes associations and
    relationships between individual variables
  • Multivariate analysis examines the complex
    inter-relationships between many variables
    simultaneously

SUMMARY
  • The ECOMAN approach provides a viable framework
    for the incorporation of biomarkers into
    environmental management strategies
