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

Environmental Risk Classification
Predicted Environmental Concentration (PEC)
PEC is calculated according to the following formula:
PEC (μg/L) = calculated with F pen refined (2018 draft guideline)
PEC = 0.0027 μg/L
Where:
With :
DOSEai = Maximum daily dose consumed per inhabitant = 100 mg
Fpen = Percentage of market penetration = 0.01
WASTEWinhab = Amount of wastewater per inhabitant per day = 200 L/inh/day
DILUTION = dilution factor = 10
PECSURFACEWATER= 0.5 µg/L
Since this value is higher than 0.01 µg/L a Fpen refined has been used.
With :
PREGION Prevalence for the region = 0.02
tTreatment Duration of one period treatment : ll type of surgery are performed in one day
nTreatment Number of treatment / year : as calculated : 1
Nd : Number of day / year : 365
Fpen refined=0.02x1x1/365
Fpen refined = 0.0000548
PECSURFACEWATER=(100 x 0.0000548)/(200 x 10)
PECSURFACEWATER = 0.0027 µg/L
Log Kow:
The partition coefficient experimental determination could not have been determined with the OECD Guidelines due to the stability and the solubility of the product but there are values for log Kow found in the literature:
-
The log Kow from the EPA (Environmental United States Protection Agency) is evaluated at -4.
-
The calculated log Kow by the ACD/Chemsketch software is -5.9.
Litterature data show that the Log Kow of suxamethonium chloride is highly negative, the substance is therefore considered to have low potential for bioaccumulation.
