Measuring transport of lawn-applied herbicide acids from turf to home: correlation of dislodgeable 2,4-D turf residues with carpet dust and carpet surface residues

Article Abstract:

A high correlation between both carpet dust levels and carpet surface dislodgeable residue levels and turf dislodgeable residue levels was gleaned from a measurement of the transport of lawn-applied herbicides into the home through walking over treated turf. Turf dislodgeable residues were 0.1% to 0.2% of turf application levels. Transfer efficiency of herbicides from turf to carpet dust was 3% of the turf dislodgeable residues, while transfer from turf to carpet surface was 0.3% of the turf dislodgeable residues.

Comparison of an enzyme immunoassay and gas chromatography/mass spectrometry for the detection of atrazine in surface waters

Article Abstract:

The reliability of an enzyme immunoassay (EIA) for atrazine was assessed by comparing its ability to analyze the herbide content of water samples with that of existing gas chromatography/mass spectrometry (GC/MS) methods. Results revealed that the EIA enjoyed internal consistency and that atrazine concentrations measured by EIA and by GC/MS had a high correlation. EIA, however, yielded very few false positives and produced no false negatives.

Patterns of herbicide contamination in selected Vermont streams detected by enzyme immunoassay and gas chromatography/mass spectrometry

Article Abstract:

Water samples in four Vermont streams were analyzed for atrazine content using enzyme immunoassay to determine the patterns of contamination of the herbicide in streams. Gas chromatography and mass spectrometry techniques were used to analyze water and sediment samples. The results of the analyses as based on the location of sampling sites are presented.
