Miljöpåverkan
Natriumpolystyrensulfonat
Miljörisk:
Risk för miljöpåverkan av natriumpolystyrensulfonat kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning:
Det kan inte uteslutas att natriumpolystyrensulfonat är persistent, då data saknas.
Bioackumulering:
Det kan inte uteslutas att natriumpolystyrensulfonat kan bioackumuleras, då data saknas.

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 = 1,23 µg/L
Where:
A = 8984.6162 kg (total sold amount API in Sweden year 2021, data from IQVIA)
R = 0% removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation)
P = number of inhabitants in Sweden = 10*106
V (L/day) = volume of wastewater per capita and day = 200 (ECHA default) (Ref I)
D = factor of dilution of waste water by surface water flow = 10 (ECHA default) (Ref I)
Predicted No Effect Concentration (PNEC)
Ecotoxicological studies
No data available.
Environmental Risk Classification (PEC/PNEC ratio)
Risk of environmental impact of sodium polystyrene sulfonate cannot be excluded, since there is no data to calculate a PEC/PNEC ratio.
Degradation
No data available.
Justification of chosen bioaccumulation phrase:
The potential for persistence of sodium polystyrene sulfonate cannot be excluded due to lack of data.
Bioaccumulation
No data available. No data found in publicly open available sources.
Excretion (metabolism)
No data available.
