Miljöpåverkan
Arseniktrioxid
Miljörisk:
Risk för miljöpåverkan av arseniktrioxid kan inte uteslutas då det inte finns tillräckliga ekotoxikologiska data.
Nedbrytning:
Det kan inte uteslutas att arseniktrioxid är persistent, då data saknas.
Bioackumulering:
Arseniktrioxid har låg potential att bioackumuleras.

Miljörisk
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 = 3,18*10-6 μg/L
Where:
A = 0,02323756 kg (total sold amount API in Sweden year 2023, data from IQVIA). Reduction of A may be justified based on metabolism data.
R = X % 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)
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
Estimated LogKow = - 2,98 (Ref 2)
If LogKow < 4 at pH 7 the substance has low potential for bioaccumulation.
