RQ values in bold indicate exceedence of acute risk to listed species LOC (0.1) and chronic risk LOC (1.0). 

(1) Acute dose-based RQs are based on the dose-based EECs divided by the adjusted LD50 for rat (range: 3.9-21 mg/kg-bw) 

based on the body weights of the assessed species. 

(2) Chronic dose-based RQs were based on dose-based EECs divided by adjusted rat NOAECs (range: 0.29-1.57 mg/kg bw) 

based on the body weights of the assessed species). 

(3) Chronic dietary-based RQs were based on dietary EECs divided by the chronic dietary NOAEC for rats (15 mg/kg diet). 

 See Section II of this Appendix for calculation of dose-based EECs, diet-based EECs, and adjusted LD50 and NOAEC values.

RQ values in bold indicate exceedence of acute risk to listed species LOC (0.1) and chronic risk LOC (1.0). 

(1) Acute dose-based RQs are based on the dose-based EECs divided by the adjusted LD50 for mallard (range: 14.5-35.4 mg/kgbw) based on the body weights of the assessed species. 

(2) Acute dietary-based RQs are based on the dietary EECs divided by the avian acute dietary LC50 (805 mg/kg diet). 

(3) Chronic RQs are based on the dietary EECs divided by the avian NOAEC (30 mg/kg diet). See Section II of this Appendix

RQ values in bold indicate exceedence of acute risk to listed species LOC (0.1) and chronic risk LOC (1.0). 

(1) Acute dose-based RQs are based on the dose-based EECs divided by the adjusted LD50 for rat (range: 3.9-21 mg/kg-bw) 

based on the body weights of the assessed species. 

(2) Chronic dose-based RQs were based on dose-based EECs divided by adjusted rat NOAECs (range: 0.29-1.57 mg/kg bw) 

based on the body weights of the assessed species). 

(3) Chronic dietary-based RQs were based on dietary EECs divided by the chronic dietary NOAEC for rats (15 mg/kg diet). 

 See Section II of this Appendix for calculation of dose-based EECs, diet-based EECs, and adjusted LD50 and NOAEC values.

II. Example KABAM Calculations for Florida Citrus (non-bearing) 

The tables below provide the input parameters, calculations and output from the KABAM model 

used to estimate risks to piscivorous birds and mammals from labeled uses of endosulfan. 

Table J-6. Input Parameters for chemical characteristics of endosulfan (FL Citrus n.b.). 

Characteristic Value Comments/Source 

Pesticide Name Endosulfan 

(FL Citrus n.b.) 

Log KOW 4.46 

Weighted mean of Kow for alpha- (54,954), beta endosulfan 

(61,660), and endosulfan sulfate (5,129) based on peak EEC ratio of 

30% alpha, 15% beta and 55% endosulfan sulfate(1).

KOW 28556 No input necessary. This value is calculated automatically 

from the Log KOW value entered above. 

KOC (L/kg OC) 10600 Input value used in PRZM/EXAMS to derive EECs. See 

Section 3.2 of the document.

Time to steady 

state (TS; days) 10 This value is calculated automatically from the Log KOW value entered above. 

Pore water EEC 

(μg/L) 2.99 

1 in 10 year 21-d EEC from PRZM/EXAMS benthic file. This 

EEC represents the freely dissolved concentration of the 

pesticide in the pore water of the sediment. 21-d average 

selected based on the expected time it takes for endosulfan 

to reach steady state. 

Water Column 

EEC (μg/L) 5.15 

1 in 10 year 21-d EEC from PRZM/EXAMS water column file. 

This EEC represents the freely dissolved concentration of the 

pesticide in the pore water of the sediment. 21-d average 

selected based on the expected time it takes for endosulfan 

to reach steady state. 

(1) Corresponds to a Log Kow of 4.74 and 4.79 for alpha and beta isomers (MRID 414215-01) and a log Kow for 

endosulfan sulfate of 3.71 (Schenker et al. 2005).

constants respectively, through respiration. kD and kE represent the uptake and elimination 

coefficients, respectively, through diet. kM represents the metabolism rate constant.
