Miljöpåverkan (Läs mer om miljöpåverkan)

Miljöinformationen för formoterol är framtagen av företaget AstraZeneca för Bevespi Aerosphere, Brimica Genuair, Budfor, Duaklir Genuair, Edoflo, Eltren, Eltren forte, Eltren mite, Gardette, Gardette forte, Gardette mite, Oxis® Turbuhaler®, Symbicort, Symbicort® Turbuhaler®, Symbicort® forte Turbuhaler®, Symbicort® mite Turbuhaler®

Miljörisk: Användning av formoterol har bedömts medföra försumbar risk för miljöpåverkan.
Nedbrytning: Formoterol är potentiellt persistent.
Bioackumulering: Formoterol har låg potential att bioackumuleras.

Detaljerad miljöinformation


PEC/PNEC = 0.00015 μg/L /94 μg/L = 1.6*10-6 → PEC/PNEC = ≤ 0.1


Environmental Risk Classification

Predicted Environmental Concentration (PEC)


PEC is based on following data:


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

PEC (µg/L) = 1.5*10-6*A*(100-R)


A (kg/year) = total sold amount API in Sweden year 2017, data from IQVIA (former IMS Health and Quintiles). 

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

hydrolysis or biodegradation) = 0 if no data is available.

P = number of inhabitants in Sweden = 9 *106

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

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

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


A =  1.00 kg

R = 0


PEC = 1.5 * 10-6 * 1.00 * (100-0) = 0.00015 μg/L


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


Metabolism and excretion


The major part of the dose of formoterol fumarate dihydrate is eliminated via metabolism. After inhalation, 8-13% of the delivered dose is excreted unmetabolised in the urine. (ref 2).

Predicted No Effect Concentration (PNEC)


Short-term test have been undertaken for species from three trophic levels, based on internationally accepted guidelines. The most sensitive species of these is the green alga, Pseudokirchneriella subcapitata (formerly known as Selenastrum capriocornutum), and the growth rate end point has been applied. Therefore, the PNEC is based on the growth rate results (EC50) from the toxicity to P subcapitata study, and an assessment factor of 1000 is applied in accordance with ECHA guidance (Ref 6).


PNEC = 94 000/1000 = 94 µg/L


Environmental risk classification (PEC/PNEC ratio)

PEC/PNEC = 0.00015 µg/L /94 µg/L =1.6*10-6

PEC/PNEC ≤ 0.1 


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


Partition coefficient Octanol/Water

Log D = 0.41, pH 7.4 @ 25 °C (ref. 7)


Since Log D < 4 the phrase ‘Formoterol fumarate dihydrate has low potential for bioaccumulation’ is assigned.


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