Environment Canada:

• Industrial use

• Solely for a Food and Drugs Act use

• Dual use (industrial and Food and Drugs Act uses)

• NSN package should include:

• Completed NSN Reporting Form (including appendices)

• Attachments (if any)

• Fee (if required)

- 44 -

Preliminary Screening

• Notifications and Client Services Section reviews the NSN package

to ensure that it meets the regulatory requirements under the

Regulations:

• Incomplete NSN package

• Unacceptable NSN package

Note: acceptability of waivers, surrogate data and test data are not reviewed at this stage

- 45 -

Risk Assessment

• Assessment occurs after the NSN package has been acknowledged

• Review and determination of data quality, acceptability of any waiver requests, surrogate data and alternate data proposals

• Assessment of potential risk to human health and the environment

NOTE: Pre-notification Consultation may

be requested to avoid delays

- 46 -

Final Assessment Outcomes

• No suspicion that the substance meets the criteria of S. 64 of CEPA

1999

• No suspicion that the substance meets the criteria of S. 64 of CEPA

1999 for the proposed uses, but may for other potential uses or

activities

• Suspicion that the substance meets the criteria of S. 64 of CEPA

1999

- 47 -

Significant New Activity

If the assessment for the notified substance determines that there is

no suspicion that the substance meets one of the criteria set out in

S. 64 of CEPA 1999 for the notified activities but there is a suspicion

that a significant new activity in relation to the substance may result

in the substance meeting the criteria, the substance can be subject

to a SNAc Notice.

- 48 -

Risk Management Measures

• Risk management measures applied to minimize any risk to human health and/or environment:

• Ministerial Condition - restrictions placed on manufacture or import activities

• Ministerial Prohibition - manufacture or import prohibited in any amounts

• Ministerial Request for additional information - prohibition of manufacture or import pending required testing

NOTE: The assessment period can be extended if there is a potential concern and more time is required to develop a risk management measure

- 49 -

Part 5

Human Health & Ecological

Risk Assessment

- 50 -

Presentation Objectives

• To communicate concepts and approaches to Risk Assessment of

new substances

• Information Collection and Evaluation

• Characterization of Entry, Fate and Exposure

• Effects Characterization

• Characterization of Risk

• Assessment Outcomes and Next Steps

- 51 -

Overview of Assessment Process

- 52 -

Information Collection

• Types of information used in evaluating new substances

– Chemical identity

– Physical-chemical properties

– Exposure information

– Effects information

• Sources of information

– Provided by Industry

– Publicly available data e.g. open literature

– “Read Across” Data

– Predictions

- 53 -

Evaluation of the Information

• Review data for quality and reliability

• Data Preference. In general, the usual order of data preference for

a particular endpoint:

1. acceptable experimental data for the substance

2. acceptable experimental data from a close structural analogue

3. reliable model predictions

4. expert judgment: in the absence of reliable data, used to provide a

qualitative description of an endpoint

- 54 -

Exposure:

• Characterization of Entry, Fate and Exposure

• Environmental Entry, Fate and Exposure

• Direct human exposure

• Indirect human exposure

• Quantification of exposure

Hazard:

• Human health effects

• Ecological effects

• Abiotic effects

Risk Assessment

Hazard x Exposure = Risk

Characterization of Entry, Fate

and Exposure

- 56 -

Environmental Entry, Fate and Exposure

• The objective is to determine how a substance enters the

environment and to understand its fate in order to establish the

exposure of humans and ecological receptors to the substance.

• Main Steps:

1. Entry characterization into the environment

2. Characterization of environmental fate and distribution

3. Quantification of exposure

- 57 -

Entry Characterization

- 58 -

Direct Human Exposure

- 59 -

• Assess direct human exposure for the notified use

• Also need to consider potential uses

• Exposure calculations based on exposure for intended or potential

uses

Indirect Human Exposure

• Calculate human exposure level via environmental media (water,

air, soil)

• Correlate PEC with mammalian subchronic toxicity results during

the hazard assessment

- 60 -

Exposure Assessment - Example

• Fragrance additive in laundry detergents

• Direct human exposure through washing laundry by hand and/or

residue on washed clothing

• Release occurring “down the drain” from use

• High removal rate by Waste Water Treatment Plant (e.g. 90%

removed, via adsorption to sludge)

• Not biodegradable but remains in biosolids

• Releases into the environment (mode of entry):

– 90% in biosolids of WWTP which are applied to land (Soil)

– 10% WWTP effluent to river (Water). Indirect human exposure through

drinking water

- 61 -

Exposure Assessment - Example

Calculate a PEC

Calculation of a

Predicted Environmental Concentration

(PEC)

is used for ecological exposure and

indirect human exposure.

- 63 -

Effects Characterization

- 64 -

• Human Health Hazard

• Ecological Hazard

Effects Characterization• Biotic Effects:

• Determine the threshold concentration of a substance that is expected to elicit adverse effects.

• Determine how the effects vary with exposure

• Evaluating information from toxicity tests measuring the effects of the substance on one or more species

• Ideally, toxicity information consists of data from different species that cover a range of food-chain levels

• Main Steps:

1. Gather and Review Effects Data

2. Select Critical Toxicity Value

3. Derive ecological Predicted No-Effects Concentration (PNEC)

4. Derive human Provisional Tolerable Daily Intake (PTDI)

• Abiotic Effects: e.g. Ozone Depleting Potential, Global Warming Potential

- 65 -

Risk Characterization

- 66 -

Risk Characterization

• Risk characterization involves using a combination of qualitative

and quantitative approaches to understand and describe the risk a

substance may pose to the environment or human health.

• Various lines of evidence are considered in a weight-of-evidence

approach to evaluate the potential for adverse effects of a

substance.

– Risk Quotients

– Margin of exposure

– Significant hazard

– Persistence and bioaccumulation

– Evidence of widespread presence and increasing concentration

– Abiotic effects

- 67 -

Outcome of Assessment and Next Steps

• Ultimately the outcome of an assessment is a recommendation

whether the substance meets the definition of “Toxic” as described

in Section 64 of the Act.

- 68 -
