Annex B           Derivation of Toxicity Reference Value for Aquatic Life

 

TRVs of Contaminants of Potential Concern (COPC) for aquatic life were evaluated to determine the Concentration of Interest (COI) for COC selection and the risk calculation for COCs.  TRVs were derived from the following sources of toxicity values, listed in order of preference:

·         Toxicity values developed and/or adopted by regulatory agencies; generally provided in the form of standards, criteria, guidance or benchmarks

·         Toxicity values published in scientific literature

 

Water quality criteria/standards of the USA (federal and state level), the United Kingdom, Canada, Australia, China and Hong Kong were reviewed.  Criteria/standards for some COCs were not identified.  For the COCs with available criteria/standards, the following rules were adopted to derive the TRV:

·             Rule 1: Criteria from Hong Kong are adopted when available and suitable

·             Rule 2: Criteria/standards for protection of marine water/saltwater biota are preferred to that of freshwater or that without clear specification (e.g. protection of aquatic environment)

·             Rule 3: Chronic criteria/standards specified with averaging time period are preferred and adopted whenever possible.  For chronic criteria/standards without specified averaging time, annual averaging time is adopted 

·             Rule 4: National criteria/standards are preferred to local criteria/standards

·             Rule 5: If more than one criteria/standards for the same COC meet the above criteria, criterion/standard with the lower value would be adopted to provide conservatism

 

The identified relevant criteria/standards were presented in Table 1; the adopted values based on the above rules were typed in bold.

g CDM (2002).

h According to CDM (2002), using the TRV based on the criterion of 20mg/L would overestimate the risks to aquatic biota.  Therefore, the criterion for sulphide was not adopted to derive TRV.

 

 

For COPCs without relevant criteria/standards adopted by agencies, TRVs were derived from toxicity data in scientific literature, based on the guidance provided by USEPA (1999b).  ECOTOX database maintained by USEPA and OECD Screening Information DataSet (SIDS) by ICPS INCHEM were reviewed for toxicity data of HAAs on aquatic life, which are summarized at the end of this Annex.

 

The ECOTOX database is a source for locating single chemical toxicity data from three USEPA ecological effects databases: AQUIRE, TERRETOX and PHYTOTOX.  Relevant literature for ECOTOX is retrieved using a comprehensive search strategy to locate worldwide aquatic and terrestrial ecological effects literature.  The majority of literature reviewed for ECOTOX is from 1972 through to present, which literature acquisition, data entry and data abstraction are continually conducted by USEPA who maintains the database.  In the ECOTOX database, all the available toxicity data of a particular chemicals in the database can be retrieved by performing query, which is conducted by entering the chemical name or CAS number of the chemicals.

 

According to USEPA (1999b), the following rules are adopted to derive COC-specific TRV from the toxicity data:

l        Rule 1: Toxicity data shall be ecologically relevant to the Study

o       Biota of concern: toxicity data for saltwater species is preferred to freshwater species

o        Ecological endpoint: ecologically relevant endpoint such as growth, reproduction and survival shall be used

l        Rule 2: The following hierarchy, in terms of decreasing preference, shall be followed for the exposure duration and study endpoint selection:

o        Chronic NOEC (No Observable Effect Concentration)

o        Subchronic NOEC

o        Chronic LOEC (Lowest Observed Effect Concentration)

o        Subchronic LOEC

o        Acute median lethality point estimate (LC50)

o        Single dose toxicity value

l        Rule 3: Uncertainty Factor (UF) shall be applied to convert toxicity test endpoint to TRV (which is equivalent to a chronic NOEC), if the toxicity test endpoint is not a chronic NOEC

o         Chronic LOEC should be multiplied by a UF of 0.1

o         Subchronic LOEC should be multiplied by a UF of 0.1

o         Acute lethal value (such as LC50) should be multiplied by an UF of 0.01

           

The following guidelines were adopted to generally determine exposure duration:

l        For fish:

o         A chronic test lasts for more than 90 days

o         A subchronic test lasts from 14 to 90 days

o         An acute test lasts less than 14 days

l        For other marine organisms:

o        A chronic test lasts for 7 or more days

o        A subchronic test lasts from 3 to 6 days

o        An acute test lasts less than 3 days

 

The derived TRVs for COCs without relevant criteria/standards are presented in Table 2
