METHOD 627 - DINITROANILINE PESTICIDES

Method 627 is applicable to the determination of dinitroaniline pesticides in industrial and municipal discharges as provided under 40 CFR
136.1 by gas chromatography. However, it fails to distinguish between Benfluralin, Ethalfluralin, and Trifluralin. When more than one of these
materials may be present in a sample, the results are reported as Trifluralin.

METHOD 629 - BLADEX (CYANAZINE)
Method 629 is applicable to the determination of Cyanazine in municipal and industrial wastewater. It is a high-performance liquid
chromatographic (HPLC) method. HPLC conditions are described which allow for separation and measurement of cyanazine in the extract
by HPLC with a UV detector. The method provides for an optional Florisil column cleanup procedure to aid in the elimination or reduction of
interferences.

METHOD 630/630.1 - DITHIOCARBAMATE PESTICIDES
Method 630 is applicable to the determination of dithiocarbamate pesticides. It is the colorimetric method for the determination of the
dithiocarbamate pesticides compounds in industrial and municipal discharges as provided under 40 CFR 136.1. (Note that this method fails
to distinguish between the individual dithiocarbamates, for all results are reported as Ziram). Carbon disulfide is an interferant.

Method 630.1 is applicable the determination of the dithiocarbamate pesticide compounds listed in municipal and industrial discharges as
provided under 40 CFR 136.1, by total residue gas chromatography. This method includes procedures to purge CS2 from the wastewater
prior to acid hydrolysis of the sample. A vortex evaporator is used for CS2 removal.

METHOD 631 - BENOMYL AND CARBENDAZIM
Method 631 is applicable to the determination of Benomyl and Carbendazim by high performance liquid chromatography (HPLC) in industrial
and municipal discharges as provided under 40 CFR 136.1. Note that Benomyl is hydrolyzed to carbendazim, and both compounds are
measured and reported as carbendazim.
