# SAR Aliphatic Amines 8/2008

FISH 96-h LC50 (Mortality)

ESTIMATED TOXICITY: The fish 96-h LC50 values used to develop this SAR were measured and the octanol water partition coefficient s (Ko w) were calculated usi ng the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h LC50 (mmol/L) = -0.6016 (log Kow) + 0.4479

The LC50 is in millimoles per liter (mM/L); N = 11 7 + 2 3; and the Coefficient of Determination (R 2 

# ) = 0.7609. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

# APPLICATION: This SAR may be used to estimate toxicity for aliphatic amine s

.
LIMITATIONS: For aliphatic amines with log Kow values greater tha n 7.0, a test duration of greater than 96 hours may be required for proper expression of toxicity. Al so, if the toxicity value obtained by the use of this equation exceeds the water solubility of t he compound (measured or estimated), mortalities greater than 50% would not be expected in a saturated solution during an exposure period of 96 hours.

ESTIMATED TOXICITY: The daphnid 48-h LC50 values used to develop this SAR were measured, and the octanol water partition coefficient s (Ko w) were calculated usi ng the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 48-h LC50 (mmol/L) = -0.5119 (log Kow) - 0.7278

The LC50 is in millimoles per liter (mM/L); N = 44 + 15 ; and the Coefficient of Determination (R 2 

# ) = 0.554. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

Al so, if the acute toxicity value obtained by the use of this equation exceeds the water solub ility of the compound (measured or estimated), significant mortalities would not be expected in a saturated solution during an exposure period of 48 hours.

GREEN ALGAE 96-h EC50

ESTIMATED TOXICITY: The green algae 96-h EC50 values used to develop this SAR were measured, and the octanol water p artitio n coefficients (Kow) were calc ulated using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h EC50 (mmol/L) = -0.3708 (log Kow) -1.3744

The EC50 is in millimoles per liter (mM/L); N = 49 + 10; and the Coefficient of Determination (R 2 

# ) = 0.306. To convert the EC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

# SAR Aliphatic Amines 11/2007

GREEN ALGAE ChV

ESTIMATED TOXICITY: The green algae chronic values (ChV) used to devel o p this SAR were measured and the octanol water partition coefficients (Kow) were calc ulated using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log ChV (mmol/L) = -0.4862 (log Kow) - 1.5487

The ChV is in millimoles per liter (mM/L); N = 32 + 7; and the Coeffici ent of Determination (R 2 

# ) = 0.5639. To convert the ChV from mM/L to mg/L , multiply by the molecular weight of the compound.

GREEN ALGAE 96-h EC50

ESTIMATED TOXICITY: The green algae 96-h EC50 values used to develop this SAR were measured, and the octanol water p artitio n coefficients (Kow) were calc ulated using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h EC50 (mmol/L) = -0.0714 (log Kow) – 2.2481

The EC50 is in millimoles per liter (mM/L); N = 3 + 1; and the Coeffici ent of Determination (R 2 

# ) = 0.4347. To convert the EC50 from mM/L to mg/L , multiply by the molecular weight of the compound.

FISH 14-d LC50 (Mortality)

ESTIMATED TOXICITY: The fish 14-d LC50 values used to develop this SAR were measured and the octanol water partition coefficie nts (Kow) were calcula ted using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h (mmol/L) = - 1.223 (log Kow) + 3.7379

The LC50 is in millimoles per liter (mM/L); N = 1 + 1; and the Coefficient of Determination (R 2 

# ) = N/A. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the ester.

GREEN ALGAE 96-h EC50 (Growth)

ESTIMATED TOXICITY:

The green algae 96-h EC50 values used to develop this SAR were measured and the octanol wat er partition coefficient s (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h EC50 (mmol/L) = -0.6744 log (Kow) + 0.4247

The EC50 is in millimoles per liter (mM/L); N = 20 + 6; and the Coefficient of Determination (R 2 

# ) = 0.8426. To convert the EC50 from mM/L to mg/L, multiply by the molecular weight of the ester.

FISH 14-d LC50

ESTIMATED TOXICITY: The fish 14-d LC50 values used to develop this SAR were measured and the octanol water partition coefficie nts (Kow) were calcula ted using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 14-d LC50 (mmol/L) = -0.8729 log K ow 

# + 1.6375

The LC50 is in millimoles per liter (mM/L); N = 70 + 5; and the Coefficient of Determination (R 2 

# ) = 0.9173. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

Maximum K ow 

# : 6.0 Maximum MW: 1000

Limitations: If the log Kow value is greater than 5.0, or if the compound is solid and the LC50 exceeds the water solub ility by 10X , no effects at saturation are predicted.

DAPHNID 48-h LC50

ESTIMATED TOXICITY: The daphnid 48-h LC50 values used to develop this SAR were measured and the octanol wat er partition coefficient s (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 48-h LC50 = -0.8157 (log K ow 

# ) + 1.2695

The LC50 is in millimoles per liter (mM/L); N = 115 + 37; and the Coefficient of Determination (R 2 

# ) = 0.7712. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

Maximum K ow 

# : 5.0 Maximum MW: 1000

DAPHNID ChV

ESTIMATED TOXICITY: The daphnid ChV values used to develop this SAR were measured and the octanol water partition coefficie nts (Kow) were calcula ted using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 16-d ChV (mmol/L) = - 0.7469 log K ow 

# + 0.1961

The ChV is in millimoles per liter (mM/L); N = 29 + 1; and the Coefficient of Determination (R 2 

# ) = 0.8593. To convert the ChV from mM/L to mg/L, multiply by the molecular weight of the compound.

FISH (SW) 96-h LC50

ESTIMATED TOXICITY: The saltwater fish 96-h LC50 values used to develop this SAR were measured and the octanol wat er partition coefficient s (Kow) were calculated using the computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h LC50 (mmol/L) = - 0.9129 log K ow 

# + 1.8558

The LC50 is in millimoles per liter (mM/L); N = 25 + 1; and the Coefficient of Determination (R 2 

# ) = 0.6859. To convert the LC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

DAPHNID 48-h LC50 (Mortality)

ESTIMATED TOXICITY: The daphnid 48-h LC50 values used to develop this SAR were measured and the octanol water partition coeffici ents (Kow) were calculated using the co mputer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 48-h LC50 (mmol/L) = - 0.5667 (log Kow) - 0.1481

The LC50 is in millimoles per liter (mM/L); N = 63 + 7; and the Coefficient of Dete rmination (R 2

# Application: This SAR may be used to estimate toxicity for phenols.

Limitations: Phenols which contain the following groups may have ex ce ss toxi city compared with the values predicted by this SAR: 1,2-di(OH) groups (e.g., catechol)

If the log Kow value is greater than 5.5, or if the comp ound i s solid and the LC50 exceeds the water solubility by 10X, no effects at saturation are predicted.

GREEN ALGAE 96-h EC 50 (Growth)

ESTIMATED TOXICITY: The green algae 96-h EC50 values used to develop this SAR we re measured a nd the octanol water partition coefficients (Kow) were calculated using t he computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log 96-h EC50 (mmol/L) = -0.6089 (log Kow) + 0.599

The EC50 is in millimoles per liter (mM/L); N = 40 + 4; and the Coefficient of Dete rmination (R 2 

# ) = 0.6748. To convert the EC50 from mM/L to mg/L, multiply by the molecular weight of the compound.

# Application: This SAR may be used to estimate toxicity for phenols.

Limitations: Phenols which contain the following groups may have ex ce ss toxi city compared with the values predicted by this SAR:

1,2-di(OH) groups (e.g., catechol)

If the log Kow value is greater than 6.4, or if the comp ound i s solid and the EC50 exceeds the water solubility by 10X, no effects at saturation are predicted.

FISH 30-d ChV

ESTIMATED TOXICITY: The fish 30-d chronic values (ChV) used to develop this SAR were measured and the octanol water partition coefficient s (Ko w) were calculated using t he computer program, KOWWIN (Version 1.67). The SAR equation used to estimate toxicity is:

Log ChV (mmol/L) = -0.5981 (log Kow) - 0.7616

The ChV is in millimoles per liter (mM/L); N = 40; and the Coefficient of Determination (R 2 

# ) = 0.7369. To convert the ChV from mM/L to mg/L, multiply by the molecular weight of the compound.

# Application: This SAR may be used to estimate toxicity for phenols.

Limitations: Phenols which contain the following groups may have ex ce ss toxi city compared with the values predicted by this SAR:

# 1,2-di(OH) groups (e.g, catechol)

If the log Kow value is greater than 8.0, or if the comp ound i s solid and the ChV exceeds the water solubility by 10X, no effects at saturation are predicted. A test duration of more than 30 days may result in a lower chronic toxicity; at 60 days the toxicity will be 20x lower than predicted by this SAR for phenols with a log Kow of 1.5 and 4x lower for phenols with a log Kow of 5.3. For an exposure of 60 days, a separate SAR has been developed.
