FIELD C 

 Column 1 1 



(d) When a test compound, dissolved or suspended in water or any other solvent, is applied to 

 a surface which is subsequently dried to give a test compound residue, followed by submergence of 

 the surface in water for exposure of aquatic organisms (in which case "water" would be the host coded 

 in Field J), Field C is not coded. See Division 5 of Specific Directions and Explanations for Field A 

 for this coding procedure. 



3. Symbol 1 may be used to indicate NON- NEUTRALITY (pH acidic or basic) of an AQUEOUS 

 solvent 



The acidic and basic solutions included in the definition for Symbol 1 refer ONLY to aqueous 

 solutions. The symbol is not intended for unadulterated acids or bases as solvents (e. g. , lactic acid). 



4. Symbols available for additional items of Field C 



Symbols 8, C, D, E, F, J, L, V, X, Y, and Z are available for additional items for Field C. 



5. File of coded biology data on IBM punched cards arranged according to symbols for solvents 

 The CBCC has established no separate file of biology data arranged by Field C entries. 



6. Double coding in Field C 



When experiments, performed with a given test compound, are repeated using different solvents 

 and the results differ in a degree that can be distinguished by code in the evaluation fields or in the 

 action fields, separate lines should be coded to record the influence of the solvent. If the results are 

 so nearly alike that they can not be distinguished by code in Field Y, only a single line, with a single 

 solvent coded in Field C, should be constructed, with the remaining data of the other tests entered in 

 the written abstract (i. e. , Field C should not be double coded).
