— — — — — — — — —
Π (uncertainty factors)

where—

Π

is the symbol for the multiplication of a series of factors

uncertainty factors

are the factors specified in regulations 14 to 21.

(2)

If a LOAEL for a substance is available and it is less than a NOAEL for the substance, the LOAEL may be used, and regulations 14 to 21 apply accordingly.

(3)

When calculating an RfD, the NOAEL or LOAEL must be obtained from data for the specific toxic effect for which the RfD is to be calculated.

(4)

The product of the uncertainty factors must be not less than 1 and not more than 10 000.

14 Uncertainties in variation in response of human subpopulations

A value of not less than 1 and not more than 100 must be set to allow for uncertainties caused by the type and quality of the data specified in regulation 11.

(2)

The value in subclause (1) must be the product of the uncertainty factors set in accordance with regulations 17 to 21.

17 Uncertainties from lack of chronic exposure data

(1)

A value of not less than 1 and not more than 10 must be set to allow for uncertainty caused by extrapolating from the data available on the significant adverse biological effects or toxic effects of acute, sub-acute, or sub-chronic exposure to the substance to the likely effects of chronic exposure to the substance.

(2)

A value of not less than 2 and not more than 10 must be set if data on the significant adverse biological effects or toxic effects after chronic exposure is not available.

(3)

A value of 1 must be set if data on the significant adverse biological effects or toxic effects of chronic exposure to the substance is available.

18 Uncertainties in toxicological information relating to availability of NOAEL

(1)

If a NOAEL is available, a value of 1 must be set.

(2)

If a NOAEL is not available and the NOAEL is derived from a LOAEL, a value of not less than 2 and not more than 10 must be set to allow for uncertainty.

(3)

The value must be based on—

(a)

the shape and slope of the dose response curve for the substance based on the dose of the substance and the significant adverse biological effects or toxic effects of the substance; and

(b)

the nature of the significant adverse biological effects or toxic effects.

19 Uncertainties in validity, reliability, and measurement of data

(1)

A value of not less than 1 and not more than 10 must be set to allow for uncertainties in the study that the NOAEL is obtained from relating to—

(a)

the extent to which data is derived from methods that are valid; or

(b)

the reliability of data; or

(c)

the accuracy of data measurement.

(2)

A value of not less than 2 and not more than 10 must be set if the study that a NOAEL is obtained from—

(b)

is unreliable; or

(c)

does not measure accurately the specific significant adverse biological effect or specific toxic effect in the study.

(3)

A value of 1 must be set if the study that the NOAEL is obtained from—

(a)

uses methods that are statistically valid in every aspect; and

(b)

is reliable; and

(c)

measures accurately the specific significant adverse biological effect or specific toxic effect in the study.

20 Differences in biological or toxic effect

(1)

A value of not less than 1 and not more than 10 must be set to allow for differences in the nature and severity of significant adverse biological effects or toxic effects.

A value of not less than 2 and not more than 10 must be set if deficiencies exist in the data describing the significant adverse biological effects or toxic effects of the substance.

(3)

A value of 1 must be set if the data describing the significant adverse biological effects or toxic effects of the substance is considered complete for the evaluation of the substance concerned.

Potential daily exposure value

22 Potential daily exposure value to be established

If an acceptable daily exposure value or 1 or more RfD values are set for a substance, a potential daily exposure value for each exposure route must also be set for the substance by the Authority in accordance with regulation 23.

23 Formula for calculating potential daily exposure values

(1)

A potential daily exposure value must be calculated in accordance with the following formula:

acceptable daily exposure or RfD × n

where n is a value of more than 0, but not more than 1 and represents a fraction of likely exposure through a particular exposure route.

(2)

The sum of all potential daily exposure values set for a substance must be equal to or less than the acceptable daily exposure value or RfD used to calculate the potential daily exposure values.

(3)

A potential daily exposure value must be expressed in milligrams of the substance per kilogram of body weight per day.

(4)

If a substance is a mixture, a potential daily exposure value may be set for the mixture or 1 or more substances within the mixture.

Tolerable exposure limit

24 Establishment of tolerable exposure limit

(1)

A tolerable exposure limit must be set for a substance by the Authority for 1 or more environmental media if the environmental media relate to an exposure route for the substance that a potential daily exposure has been set for.

(2)

A tolerable exposure limit must be set by calculating, for each environmental medium, the concentration of the substance that would result in a person exposed to each medium receiving a dose of the substance equal to or less than the potential daily exposure set for the relevant exposure route.

(3)

A tolerable exposure limit must be expressed as a concentration of the substance for each environmental medium.

(4)

If a substance is a mixture, the Authority may set tolerable exposure limits for the substance or 1 or more components of the substance based on the assessment of the available toxicological data for the substance or 1 or more components of the substance.

25 Relevant matters for setting tolerable exposure limit

(1)

The tolerable exposure limit must be based on values set in accordance with subclause (2) for the following matters:

(a)

the extent to which exposure to a substance from an environmental medium would be acute exposure or chronic exposure:

(b)

the frequency and duration of exposure to a substance from an environmental medium:

(c)

the average body weight of people in the population likely to be exposed to a substance from an environmental medium:

(d)

the extent of absorption of the substance, the binding affinity of the substance with plasma lipoproteins or cellular receptors, or the elimination of the substance from the body.

(2)

A value set for a matter described in subclause (1) must be set by adopting as the value for the relevant matter a value that has been set—

(a)

by an international scientific or regulatory body recognised by New Zealand; or

(b)

in a convention that New Zealand has signed or ratified; or

(c)

under any other Act.

26 Adjustment of value for setting tolerable exposure limit

(1)

A value set for a matter described in regulation 25(1) may be adjusted to obtain a higher tolerable exposure limit for the following reasons:

(a)

exposure to the substance is likely to be of a shorter duration than the exposure used to set the value for the matter described in regulation 25(1)(a):

(b)

exposure to the substance is likely to be less frequent than the exposure used to set the value for the matter described in regulation 25(1)(b):

(c)

the average body weight of people likely to be exposed to the substance is likely to be greater than the body weight used to set the value for the matter described in regulation 25(1)(c):

(d)

data from human beings indicates that the substance is less readily absorbed, displays a low binding affinity to plasma lipoproteins or cellular receptors, or is eliminated more rapidly from the body than the toxicokinetic and toxicodynamic data used to set the value for the matter described in regulation 25(1)(d) indicates:

(e)

data from human beings indicates that the substance does not accumulate in human tissue.

(2)

A value may be adjusted to obtain a lower tolerable exposure limit for the following reasons:

(a)

exposure to the substance is likely to be of a longer duration than the exposure used to set the value for the matter described in regulation 25(1)(a):

(b)

exposure to the substance is likely to be more frequent than the exposure used to set the value for the matter described in regulation 25(1)(b):

(c)

the average body weight of people likely to be exposed to the substance is likely to be less than the body weight used to set the value for the matter described in regulation 25(1)(c):

(d)

data from human beings indicates that the substance is more readily absorbed, displays a binding affinity to plasma lipoprotein or cellular receptors, or is eliminated less rapidly from the body than the toxicokinetic and toxicodynamic data used to set the value for the matter described in regulation 25(1)(d) indicates:

(e)

data from human beings indicates that the substance accumulates in human tissue:

(f)

reliable medical data, accident related data, or epidemiological data shows that the substance has a greater toxic effect in 1 or more human subpopulations than in other human subpopulations.

27 Prohibition on use of substance in excess of tolerable exposure limit

(1)

A person must not use a class 6 substance in a manner that would result in a concentration of the substance in an environmental medium that exceeds the tolerable exposure limit set for the medium.

39 Uncertainties in extrapolation of ecotoxic information from other species

(1)

A value of not less than 1 and not more than 10 must be set to allow for uncertainties due to extrapolating from data on the ecotoxic effects of the substance to another species likely to be exposed to the substance in environmental media.

(2)

A value of not less than 2 and not more than 10 must be set if the data is obtained from a study of the effects of the substance on a species that is not likely to be exposed to the substance in environmental media.

(3)

A value of 1 must be set if the data is obtained from a study of the effects of the substance on a species that is likely to be exposed to the substance in environmental media.

40 Uncertainties due to extrapolation

(1)

A value of not less than 1 and not more than 10 must be set to allow for uncertainties due to extrapolating from the data available on the ecotoxic effects of the substance to the effects on a species likely to have chronic exposure to the substance in environmental media.

(2)

A value of not less than 2 and not more than 10 must be set if the data on the ecotoxic effects after chronic exposure to the substance is not available or the data available does not adequately disclose chronic effects on the species likely to have chronic exposure to the substance in environmental media.

(3)

A value of 1 must be set if the data for ecotoxic effects after chronic exposure to the substance is available and the data adequately discloses chronic ecotoxic effects on a species likely to have chronic exposure to the substance in environmental media.

41 Uncertainties due to extrapolation of ecotoxic data to natural environment

(1)

A value of not less than 1 and not more than 10 must be set to allow for uncertainty in extrapolating from data on ecotoxic effects obtained from controlled experiments, to ecotoxic effects in environmental media.

(2)

A value of not less than 2 and not more than 10 must be set if data is unavailable to demonstrate levels at which ecotoxic effects would occur in environmental media.

(3)

A value of 1 must be set if data is available that demonstrates levels at which ecotoxic effects would occur in environmental media.

42 Uncertainties in information on biodegradation and bioaccumulation

(1)

A value of not less than 1 and not more than 10 must be set if there are uncertainties as to whether the values set under regulations 39 to 41 provide adequate protection from ecotoxic effects because the substance or an ecotoxicologically significant degradation product of the substance is likely to bioaccumulate.

(2)

A value of not less than 2 and not more than 10 must be set if the values set under regulations 39 to 41 are not likely to provide adequate protection from ecotoxic effects because the substance or degradation product of the substance is likely to bioaccumulate.

(3)

A value of 1 must be set if the values set under regulations 39 to 41 are likely to provide adequate protection from ecotoxic effects whether or not the substance or degradation product of the substance is likely to bioaccumulate.

(4)

In this regulation, degradation product means a substance created as a substance breaks down or decays in the environment.

43 Additional environmental exposure limit based on secondary poisoning

(1)

An environmental exposure limit based on secondary poisoning may be set as follows:

an ecotoxicity value in units of milligrams of the substance per kilogram of body weight per day for a species of organism that is likely to be affected by secondary poisoning must be selected:

(b)

the uncertainty factors described in regulations 39 to 42 must be applied to the ecotoxicity value selected in paragraph (a) using the formula in regulation 37 to arrive at 1 or more environmental exposure limits for secondary poisoning expressed as required by regulation 37(2):

(c)

the value arrived at under paragraph (b) must be adjusted to arrive at an environmental exposure limit for secondary poisoning, considering the circumstances of exposure, including the extent of feeding on other organisms and the amount of residue of the substance in those organisms.

(2)

If an environmental exposure limit has been set for a substance for an environmental medium based on secondary poisoning and another environmental exposure limit has been set for the same substance for the same medium based on other ecotoxicological data, the lowest environmental exposure limit is the environmental exposure limit for the substance for the medium.

(3)

In this regulation, secondary poisoning means poisoning as a result of the exposure of an organism to the substance through feeding on other organisms containing residue of the substance.

44 Application of environmental exposure limit to water

An environmental exposure limit set for a substance in surface water may not be exceeded within receiving waters after reasonable mixing.
