  • Vad är miljöinformation?

Miljöpåverkan (Läs mer om miljöpåverkan)

Miljöinformationen för hydroklortiazid är framtagen av företaget Sanofi AB för CoAprovel, Karvezide, Triatec® comp, Triatec® comp mite

Miljörisk: Risk för miljöpåverkan av hydroklortiazid kan inte uteslutas då det inte finns tillräckliga ekotoxikologiska data.
Nedbrytning: Hydroklortiazid är potentiellt persistent.
Bioackumulering: Hydroklortiazid har låg 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) = 1.5*10-6*A(100-R)


PEC = 0.435 μg/L


Where:

A = 2899.0329 kg (total sold amount API in Sweden year 2015, data from IMS Health).

R = 0% removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation)

P = number of inhabitants in Sweden = 9*106

V (L/day) = volume of wastewater per capita and day = 200 (ECHA default) (Ref I)

D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (Ref I)


Predicted No Effect Concentration (PNEC)

Ecotoxicological studies

Zebrafish (Danio rerio):

LC50 96 h (mortality) > 100 000 μg/L

(Protocol: OECD203)

(Ref II)


Environmental risk classification (PEC/PNEC ratio)

The PEC/PNEC ratio could not be estimated because there is not sufficient ecotoxicological study results available, hence the summary phrase for environmental risk: "Risk of environmental impact of hydrochlorothiazide cannot be excluded, since there is not sufficient data available".


Degradation

Inherent degradability:

Results showed < 20% degradation in 28 days. (Protocol: OECD 302B) (Ref III)


Justification of chosen degradation phrase:

Hydrochlorothiazide does not pass the ready degradation test, therefore the phrase "hydrochlorothiazide is potentially persistent" is chosen.


Bioaccumulation

Partitioning coefficient:

Log Kow = -0.07 at neutral pH (experimentally determined, method unknown) (Ref IV)


Justification of chosen bioaccumulation phrase:

Since log Kow < 4 at pH 7, the substance has low potential for bioaccumulation.


Excretion

The substance is excreted almost entirely unchanged, with 50-70% of the oral dose in urine after 24 hours (Ref V).

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) = 1.5*10-6 * 1395.7 * 100

PEC = 0.209 μg/L

Where:

A = 1395.7 kg (total sold amount API in Sweden year 2015, data from IMS Health).

R = 0 % 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 = 9 *106 

V (L/day) = volume of wastewater per capita and day = 200 (ECHA default) (ECHA 2008)

D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (ECHA 2008)


Predicted No Effect Concentration (PNEC)

Ecotoxicological studies

Green algae (Pseudokirchneriella subspicata) (OECD201) (NOTOX Project 490976): 

EC50 72 h (growth rate) > 100.0 mg/L

NOEC = 100.0 mg/L


Crustacean (Daphnia magna):

Acute toxicity

EC50 48 h (immobilisation) > 100.0 mg/L (OECD202) (ECOTOXICOLOGY CIGY NO. 948128)

Chronic toxicity

NOEC 21 days (parental mortality and reproduction) = 5.6 mg/L (OECD 211) (NOTOX Study No. 464434)


Fish:

Acute toxicity (Oncorhynchus mykiss, rainbow trout)

LC50 96 h (mortality) > 100.0 mg/L (OECD203) (ECOTOXICOLOGY CIGY NO. 948130)

Chronic toxicity (Pimephales promelas, fathead minnow)

NOEC 30 days = 10.0 mg/L; no effect up to the highest concentration tested (OECD 210) (NOTOX Study No. 464445) 


Other ecotoxicity data:

Bacterial respiration inhibition

EC50 3 h > 750 mg/L

NOEC = 750 mg/L (activated sludge respiration inhibition) (OECD209) (NOTOX Project 490977)


PNEC derivation:

PNEC = 560 μg/L

PNEC (μg/L) = lowest NOEC/10, where 10 is the assessment factor used if three chronic toxicity studies from three trophic levels are available. The NOEC for Daphnia magna reproduction has been used for this calculation.


Environmental risk classification (PEC/PNEC ratio)

PEC/PNEC = 0.209 μg/L / 560 μg/L = 0.00037, i.e. PEC/PNEC ≤ 0.1 which justifies the phrase "Use of valsartan has been considered to result in insignificant environmental risk."


Degradation 

Biotic degradation

Ready degradability:

0 % degradation in 28 days, not readily biodegradable (92/69/EC (L383) C.4-C). (ECOTOXICOLOGY CIGY NO. 948127)

Simulation studies:

DT50 (total system) = 12.0 – 16.1 days  

DT90 (total system) = 39.8 – 53.6 days (OECD 308, 191 days). (RCC Study No. B40590)

< 15 % parent substance remaining at the end of the study

45-50 % non-extractable residues at the end of the study (up to two times: acetonitrile:water (4:1, v/v), followed by soxhlet acetonitrile: water (4:1, v/v))


Justification of chosen degradation phrase:

According to the pass criteria for OECD308 studies, valsartan can be classified as ‘Valsartan is degraded in the environment' (DT50 for total system < 32 days)


Bioaccumulation

Partitioning coefficient:

Log Dow = 1.2 at pH 7 (OECD117)

Log P = 2.8 at pH 2.5 (NOTOX Project 490979)

Justification of chosen bioaccumulation phrase:

Since log Dow < 4 at pH 7, valsartan has low potential for bioaccumulation.


Excretion (metabolism)

Valsartan is primarily eliminated in feces (about 83% of dose) and urine (about 13% of dose), mainly as unchanged drug. (Diovan® (valsartan) Core Data Sheet, 2014)


PBT/vPvB assessment

Valsartan cannot be considered a potential PBT substance.
