AIIDA V3.0 (AQUATIC IMPACT INDICATOR DATABASE) PRESENTATION & TRAINING
2
Planning AiiDA Webinar AiiDA kick off webinar – 17 th June 2014 14.00 -14.45: Presentation of the database 14.45 – 15.00 : Break 15.00 - 15.30 : AiiDA training 15.30 - 15.45: Software presentation 15.45 – 16.00: Questions
3
I- AiiDA presentation 1- Introduction 2- Scientific Background 3- Overall framework 4- Content and structure 5- Documentation 6- Conclusions
4
1- Introduction - What is AiiDA? - History of AiiDA - Previous release - Who is editing AiiDA?
5
What is AiiDA? ☼ AiiDA: Aquatic Impact Indicators Database ☼ Covers both fresh and saltwater species ☼ Provides substances description, aquatic toxicity tests results, risk & impact metrics
6
History of AiiDA ☼ First steps at DTU Denmark with the strong support of Pr Michael Hauschild in 2001 ☼ Further development at the EPF-Lausanne with Pr Olivier Jolliet until 2006 ☼ Exploring potential links with ERA at VU Amsterdam with Pr Nico van Straalen in 2008 ☼ Integration of Risk and Impact metrics in a unique database by Cycleco & Tools until now
7
Previous AiiDA releases V1.0 – Life Cycle Assessment metrics for 600 substances (in 2004) V2.0- Risk and some LCA based metrics for 1300 Substances (in 2008) V3.0 Main chemical features, risk and LCA based metrics for 24 000 substances (in 2014)
8
Who is editing AiiDA AiiDA V3.0 is the result of a partnership between Cycleco and Tools4env AiiDA project is directed by Dr Jerome Payet
9
2- Scientific background - Aspects of ecotoxicology - Taxonomy and ecology - Risk assessment of chemicals - Impact assessment of chemicals
10
Aspects of ecotoxicology ☼ Single substances and single species tests ☼ Laboratory experiment (variability of lab. conditions) ☼ Acute or chronic ecotoxicity tests ☼ Diversity of measures (EC50, LC50, NOECs, LOECs, etc) ☼ Effect of multiple substances (Additive concentration, ToMoA, Synergy, antagonism, etc) ☼ The QSAR estimate
11
Taxonomy and ecology ☼ Phyla or species ☼ Trophic level or biological organization level
12
Risk assessment ☼ Concept: Protecting ecosystems ☼ Consider substances individually ☼ Use safety factors ☼ Focus on the most sensitive species ☼ Define threshold per substance : PNEC ☼ Calculate environmental exposure: PEC ☼ Estimate the RISK=PEC/PNEC
13
Impact assessment ☼ Concept : Estimating environmental burdens ☼ Consider substances individually ☼ Use all data available ☼ Consider the average response of species (HC50) based on phyla or species ☼ Calculate the Effect Factor (EF) as 0,5/HC50 ☼ Estimate the env. Concentration with Fate models ☼Calculate the IMPACT=Fate Factor x Effect Factor
14
3- Overall framework - Chemical identification - Species classification - Ecotoxicity measures - Risk and impact metrics
15
Chemical identification ☼ Name, synonyms, ☼ CAS numbers, EC numbers ☼ Formula and 3D presentation
16
Species classification ☼ Taxonomy based on ITIS classification ☼ Includes plants, animals, fungi and bacteria ☼ 10159 species and 39 phyla covered
17
Ecotoxicity measures ☼ Mainly single species and single substance tests ☼ Acute and single exposure ☼ EC50, LC50, NOECs, LOECs, ☼ Conversion of all measures in EC50s ☼ Use of QSAR when data are missing
18
Risk and impact metrics ☼ Different experimental PNEC (most sensitive species& safety factors) ☼ Statistical PNEC (HC5 based on SSD) ☼ HC50 based on phyla (acute & chronic) ☼ HC50 based on species (acute & chronic)
19
4- Content & structure - Chemical description - Ecotoxicity tests library - Impact and Risk calculation - Substances comparison - Group of substances comparison
20
Chemical description ☼ Name ☼ CAS and EC numbers ☼ Formula & representation ☼ Molecular weight ☼ Chemical group ☼ Functional group ☼ Usage
21
Ecotoxicity tests library ☼ Presentation of all ecotoxicity tests per substance and per species ☼ Providing uncertainty of ecotoxicity test ☼Full traceability of test results with online link to the documentation related to the test.
22
Impact and risk calculation ☼ Impacts and risk calculated based on US and EU methods, including uncertainty ☼ Providing indicative (non official) experimental PNECs values for diverse media for each substance ☼ Present statistical PNECs with graphical presentation and uncertainty ☼ Providing HC50 for phyla or species graphical presentation and uncertainty
23
Substances comparison ☼ Selection of up to 5 substances for SSD (or PSD) comparison (Substitution purpose) ☼ Comparison of substances with all existing substances (prioritization purpose)
24
Group of substances comparison ☼ Search tool with logical connectors for extracting groups of substances (up to 200 chemicals) ☼ Comparison of all substances of the group with all existing substances
25
5- Documentation - Methodological guideline (English and French) -User guide (English and French) - General methodology framework for impacts assessment on ecosystems (English)
26
6- Conclusions - Is AiiDA really usefull? - How can you get the database? - Further steps?
27
Is AiiDA really useful? It can help for … ☼ Saving time for collecting data ☼ Fast screening of data availability ☼ Full traceability of data ☼ Priorization of substances ☼ Uncertainty calculation ☼ Comparing substances ☼ Evaluation of impacts of numbers of subst. ☼ Updating Life Cycle Assessment methods...
28
How can I get AiiDA? Three type of licenses: ☼ Free License : all test results provided ☼ Standard: Full access to the library of tests with complete traceability ☼Premium: Full access to all metrics calculation with uncertainty and the library of tests with full traceability.
29
Further steps - Minor update of V3 following REACH (every 6 months) - Updates of new functions for minor changes - Versioning of the database - Major Changes in functions and structure will be done from 2015 and delivered in the V4 version in 2018.
