FIELD T-2 

 Columns 58, 59, 60, and 61 



BIOLOGICAL STATE, QUAUTY, OR PROCESS 



ACTED ON OR PRODUCED BY THE TEST COMPOUND 



OR SECONDARY COMPOUND 



Gross response. (Use Symbol 1 only with 

 Symbol of Field T-1; together, the 

 symbols mean "does not cause response 

 of any type". ) 



Death caused by the test compound (Sym- 

 bols 11 and 111, below) when adminis- 

 tration has been by a single dose (not 

 continuous) or when the administration 

 has been continuous or by repeated doses 

 for a maximum of 24 hours or less. The 

 time to death may be >24 hours, if the 

 administration is by a single dose, but if 

 administration is continuous or multiple, 

 death must occur within 24 hours in order 

 to be coded by Symbols 11 or 111. 



I I Death produced under the conditions 



described above, but only when the 

 lethal dose has not been determined 

 for the individual treated (or not 

 determined for the individual of a 

 group treated collectively). 



III Death produced under the conditions 



described above, but only when the 

 lethal dose has been determined for 

 the individual treated (or for the indi- 

 vidual of a group treated collectively). 

 ACUTE TOXICITY 



Death caused by the test compound (Sym- 

 bol 112) when administration has been only 

 by continuous or multiple doses for more 

 than 24 hours and when the time to death is 

 more than 24 hours. 



112 Death produced under the conditions 



described immediately above, whether 

 the lethal dose has or has not been 

 determined for the individual treated 

 (or for the individual of a group treated 

 collectively). 

 CHRONIC TOXICITY 



Note: Use of Symbols 11, 111, and 112 

 is restricted to coding death caused in 

 larger organisms, including arthropods 

 not infesting a living host. Death of 

 parasitic, pathogenic, and all micro- 

 organisms is coded by symbols of the 

 17-- and 18-- series. Death in a popu- 

 lation of arthropods infesting a living 

 host is coded by symbols of the 13-- 

 series. Consult the Key.

Local toxicity. (In addition to these 

 states of toxic response, there are 

 other pathological states listed through- 

 out Field T-2, especially in the symbol 

 series 4 . ) 



Irritation 



Inflammation 



Depilation 



Vesication 



Pruritus 



Scorching, burning 



Abscess 



Contact dermatitis (primary irritation) 



Allergic dermatitis (sensitization) 



Foreign body giant cell formation 



Water-soaking or water-logging (plant 

 tissues or organs) 



Systemic toxicity 



Acute toxic symptoms 



General, non-acute toxic symptoms; 

 "side effect" such as general malaise, 

 lassitude, sleepiness, headache, 

 dizziness, nausea, vomiting, etc. 



Paralysis 



Undefined paralysis; catalepsy. (Use 

 this symbol for "knockdown" effect of 

 insecticide tests. ) 



Flaccid paralysis 



Spastic paralysis 



Collapse; prostration 



Syncope 



Coma; stupor 



Convulsion 



Tonic convulsion 



Clonic convulsion
