alpha-HCH3

1The 2,4-D analysis measures the acid form of this herbicide that primarily results from its application as an amine salt. However, some 2,4-D acid is formed from the hydrolysis of various 2,4-D esters, including 2,4-D methyl ester.

2The laboratory analyzes the individual components alpha-Endosulfan and beta-Endosulfan.

3alpha-HCH is both an impurity in lindane and a degradate of lindane.

4Only the cis- and trans-isomers were analyzed. Both were detected.
