Miljöpåverkan
Miljöinformationen för prometazin är framtagen av företaget Meda för Lergigan® forte
Miljörisk:
Risk för miljöpåverkan av prometazin kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning:
Det kan inte uteslutas att prometazin är persistent, då data saknas.
Bioackumulering:
Prometazin har hög 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) = 1.37*10-6*A(100-R)
PEC = 0.085 μg/L
Where:
A = 617.65 kg (total amount API of promethazine hydrochloridein Sweden year 2020, data from IQVIA). (Ref. 1)
R = removal rate = 0% (no data available)
P = number of inhabitants in Sweden = 10*106
V (L/day) = volume of waste water per capita and day = 200 (ECHA default) (Ref. 2)
D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (Ref. 2)
Ecotoxicological studies
No ecotoxicological data available.
Degradation
No degradation data available.
Bioaccumulation
An experimentally derived Log P of 4,81 (Ref. 3) indicates that promethazine has high potential for bioaccumulation.
Log P > 4 which justifies use of the phrase “Promethazine has high potential for bioaccumulation”.
