Miljöpåverkan
Paklitaxel
Miljörisk:
Risk för miljöpåverkan av paklitaxel kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning:
Det kan inte uteslutas att paklitaxel är persistent, då data saknas.
Bioackumulering:
Paklitaxel har låg potential att bioackumuleras.

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 * 5.53 * (100-0)
Where:
A = 7,61 kg (total sold amount API in Sweden year 2021, data from IQVIA).
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 = 10*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)
PEC = 1.0*10-3 μg/L
According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of paclitaxel is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) is below the action limit 0.01 μg/L.
Predicted No Effect Concentration (PNEC)
No data available so cannot be calculated.
Environmental risk classification (PEC/PNEC ratio)
Cannot be calculated due to unavailable PNEC.
Nedbrytning
No data is available.
Bioackumulering
LogP = 3 (Ref 2)
Method used: not known
If Log P < 4 at pH 7 the substance has low potential for bioaccumulation.
