  • Vad är miljöinformation?

Miljöpåverkan (Läs mer om miljöpåverkan)

Salbutamol

Miljörisk: Risk för miljöpåverkan av salbutamol kan inte uteslutas då det inte finns tillräckliga ekotoxikologiska data.
Nedbrytning: Salbutamol är potentiellt persistent.
Bioackumulering: Salbutamol har låg potential att bioackumuleras.

Environmental Risk Classification

Predicted Environmental Concentration (PEC)

PEC is calculated according to the following formula:

PEC (μg/L) = (A*109*(100-R))/(365*P*V*D*100) = 1.5*10-6*A(100-R)

PEC = 0.0085 μg/L


Where:

A = 56.57 kg (total sold amount API in Sweden year 2017, data from IQVIA).

R = 0% removal rate (conservatively, it has been assumed there is no loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation).

P = number of inhabitants in Sweden = 9 *106

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

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


Predicted No Effect Concentration (PNEC)

Ecotoxicological studies

Algae

No data


Water flea (Daphnia magna):

Acute toxicity

EC50 48 h (immobility) = 240,000 μg/L (OECD 202) (Reference 6)


Water flea (Ceriodaphnia dubia):

Chronic toxicity

NOEC 8 days (reproduction) = 100,000 μg/L (USEPA 1002) (Reference 9)


Fish:

Acute toxicity

No data

Chronic toxicity

No data


Microorganisms in activated sludge:

EC50 3 h (inhibition) = 830,000 µg/L (OECD 209) (Reference 5)


PNEC cannot be calculated because data is not available for all three (algae, crustacean and fish) of the toxicity endpoints.


Environmental risk classification (PEC/PNEC ratio)

Risk of environmental impact of salbutamol cannot be excluded, since there is not sufficient ecotoxicity data available.


Degradation

Biotic degradation


Ready degradability:

1% degradation in 28 days (TAD 3.11) (Reference 7)


Inherent degradability:

No Data


Soil Degradation

1.3 to 38.7% degradation in 64d (TAD 3.12) (Reference 8)


Abiotic degradation


Hydrolysis:


DT50 > 1 year (OECD 111) (Reference 4)


Photolysis:


No data


Justification of chosen degradation phrase:


Salbutamol is not readily degradable or inherently degradable. The phrase “Salbutamol is potentially persistent in the environment” is thus chosen.


Bioaccumulation


Partitioning coefficient:

Log Dow = -2.80 at pH 7 (TAD 3.04). (Reference 3)


Log Dow at pH5 = -1.50

Log Dow at pH7 = -2.80

Log Dow at pH9 = -2.80


Justification of chosen bioaccumulation phrase:

Since log Dow < 4 at pH 7, the substance has low potential for bioaccumulation.


Excretion (metabolism

The primary route of elimination of hydrofluoroalkane-propelled albuterol (HFA) parent or primary metabolite compound is through the kidney. After an IV dose of racemic albuterol, between 24% to 46% of the R enantiomer is excreted unchanged in the urine (Reference 2)


PBT/vPvB assessment

Salbuatmol does not fulfil the criteria for PBT and/or vBvP.

All three properties, i.e. ‘P’, ‘B’ and ‘T’ are required in order to classify a compound as PBT (Reference 1). Salbutamol does not fulfil the criteria for PBT and/or vBvP based on log Dow < 4.
