PEC/PNEC = 0.000160 μg/L /94 μg/L = 1.71x10-6

PEC/PNEC ≤ 0.1


Environmental Risk Classification


Predicted Environmental Concentration (PEC)

PEC is based on following data and calculated using the equation outlined in the fass.se guidance (Ref 1):


PEC (µg/L) = (A*109*(100-R))/(365*P*V*D*100)

PEC (µg/L) = 1.37*10-6*A*(100-R)

PEC = 1.37*10-6 *1.171*(100-R)                            

= 0.000160 µg/L


A (kg/year) = total sold amount API in Sweden year 2023, data from IQVIA/Lif

= 1.171 kg

R (%) = removal rate (due to loss by adsorption to sludge particles, by volatilization,

hydrolysis or biodegradation)

= 0 (default)

P = number of inhabitants in Sweden

= 10*106

V (L/day) = volume of wastewater per capita and day

= 200 (default, Ref 1)

D = factor for dilution of waste water by surface water flow

= 10 (default, Ref 1)


(Note: The factor 109 converts the quantity used from kg to μg).


(Note: Whilst formoterol is metabolised in the body, little is known about the ecotoxicity of the metabolites. Hence, as a worst case, for this calculation, it is assumed that 100% of excreted metabolites have the same ecotoxicity as parent formoterol).


Metabolism and excretion

Formoterol is rapidly absorbed and inactivated via conjugation reactions to form O‑demethylated and deformylated metabolites. Pharmacokinetic studies report that 62% of the administered dose is recovered in urine and 24% in faeces, with urinary excretion of unchanged formoterol accounting for between 4 and 8% of the nominal dose (Ref. 2)

Predicted No Effect Concentration (PNEC)
Short-term tests have been undertaken for species from three trophic levels, based on internationally accepted guidelines. Therefore, the PNEC is based on the lowest relevant EC50 value, which was reported for the growth rate of the green algae (Selenastrum capricomutum), 94 mg/L (equivalent to 94,000 µg/L) and an assessment factor of 1000 is applied, in accordance with ECHA guidance (Ref. 6).


PNEC = 94 000/1000 µg/L = 94 µg/L


Environmental risk classification (PEC/PNEC ratio)

PEC = 0.000160 µg/L

PNEC = 94 µg


PEC/PNEC = 1.71 x 10-6


The PEC/PNEC ratio decides the wording of the aquatic environmental risk phrase, and the risk phrase for PEC/PNEC ≤ 0.1 reads as follows:“Use of formoterol fumarate dihydrate has been considered to result in insignificant environmental risk”. 

In Swedish: “Användning av formoterol fumarat dihydrat har bedömts medföra försumbar risk för miljöpåverkan” under the heading “Miljörisk”.

Biodegradation

Based on the data above and lack of further studies, the phrase “Formoterol fumarate dihydrate is potentially persistent” is chosen.

In Swedish: “Formoterol fumarat dihydrat är potentiellt persistent ” under the heading ”Nedbrytning”.


Bioaccumulation

As formoterol fumarate dihydrate is ionisable within the environmentally relevant range, the octanol-water partition coefficient was measured at pH 5,7 and 9. As the LogDOW results are all below 4, the phrase: ‘Formoterol fumarate dihydrate has low potential for bioaccumulation’ is therefore assigned.

In Swedish: ”Formoterol fumarat dihydrat har låg potential att bioackumuleras” under the heading ”Bioackumulering”.

Environmental Risk Classification


Predicted Environmental Concentration (PEC)

The PEC is based on the following data and calculated using the equation outlined in the fass.se guidance (Ref. 1):

PEC (µg/L)       = (A*109*(100-R))/(365*P*V*D*100)

PEC (µg/L)       = 1.37*10-6*A*(100-R)

PEC                  = 1.37 * 10-6 *0.8938*(100-0)

= 0.00012 µg/L


Where;

A (kg/year)      = total sold amount API in Sweden year 2023, data from IQVIA

= 0.8938 kg

R (%)                = removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation) = 0%

P                      = number of inhabitants in Sweden = 10 x 106

V (L/day)          = volume of wastewater per capita and day = 200 L/day (Ref. 1)

D                      = factor for dilution of waste water by surface water flow = 10 (Ref. 1)


(Note: The factor 109 converts the quantity used from kg to μg)

Predicted No Effect Concentration (PNEC)

Short term data is available for species from three trophic levels. The PNEC is therefore based on the lowest EC50, for Daphnia magna, with an assessment factor of 1000 applied in accordance with ECHA guidance (Ref. 4).


PNEC = 33.0 mg/L / 1000 = 33.0 μg/L


Environmental risk classification (PEC/PNEC ratio)


PEC/PNEC = 0.00012 µg/L / 33.0 µg/L = 0.0000036 = 3.6 x 10-6


As the PEC/PNEC ratio is ≤ 0.1, the following risk statement in assigned:

Use of glycopyrronium bromide has been considered to result in insignificant environmental risk.

As the measured LogDOW < 4 at pH 7, the following phrase applies: Glycopyrronium bromide has low potential for bioaccumulation.

In Swedish: Glykopyrronium bromid har låg potential att bioackumuleras.
