“…Likewise, in our study, as previously described (Pawlisz et al, 1998), rates of pesticide degradation were in general faster under aerobic than anaerobic conditions (except for the value corresponding to C 3 in the absence of nitrate) (Table 3). Under aerobic conditions, in agreement with Khalil et al (2005), the presence of nitrates seemed to have an inhibitory effect on deltamethrin degradation rates (Figs.…”

The effects of deltamethrin, in the presence and absence of nitrate, on soil microbial activity (as reflected by the rates of soil microbial basal respiration, denitrification, and methanogenesis) were studied in a riparian wetland soil under both aerobic and anaerobic conditions. A microcosm study was carried out with soil collected from the vicinity of a wetland. The soil was then amended with 50, 125, and 250 mg deltamethrin kg j1 dry weight soil, in the presence and absence of 20 mg N-NO 3 j kg j1 dry weight soil. Half-life values for deltamethrin degradation ranged from 27 to 291 days, depending on experimental conditions. Nitrates had an inhibitory effect on deltamethrin degradation. Deltamethrin, under anaerobiosis, had an inhibitory effect on soil respiration; this effect was reversed in the presence of nitrate. An antagonistic effect between deltamethrin degradation and denitrification activity was observed. In the presence of nitrate, the activation of denitrifying bacteria led to competitive inhibition of methanogens. It was concluded that deltamethrin, designed to affect specific functions of its target organisms, also has an effect on nontarget organisms, that is, the soil microbial community. To our knowledge, this is the first report on the degradation and environmental impact of deltamethrin in a riparian wetland soil.

“…The use of glass jars minimizes adsorption of organic chemicals to collection containers. Samples were collected on January 25 and February 20, 2001, following the first runoff-generating rainfall of two storm systems (January 23-29, February [17][18][19][20][21][22][23][24][25]2001). In each orchard section, diazinon-or esfenvalerate-sprayed runoff samples for toxicity testing were collected in three rows for each ground cover type (Table 1).…”

Organophosphorous (OP) insecticides, especially diazinon, have been detected routinely in surface waters of the Sacramento and San Joaquin River watersheds, coincident with rainfall events following their application to dormant orchards during the winter months. Preventive best management practices (BMP) aim at reducing off-site movement of pesticides into surface waters. Two proposed BMPs are: The use of more hydrophobic pyrethroid insecticides believed to adsorb strongly to organic matter and soil and the use of various types of ground cover vegetation to increase the soil's capacity for water infiltration. To measure the effectiveness of these BMPs, storm water runoff was collected in a California prune orchard (Glenn County, CA, USA) during several rainstorms in the winter of 2001, after the organophosphate diazinon and the pyrethroid esfenvalerate were applied to different orchard sections. We tested and compared acute toxicity of orchard runoff from diazinon- and esfenvalerate-sprayed sections to two species of fish (Pimephales promelas, Onchorhynchus mykiss) and three aquatic invertebrates (Ceriodaphnia dubia, Simocephalus vetelus, Chironomus riparius), and determined the mitigating effect of three ground cover crops on toxicity and insecticide loading in diazinon-sprayed orchard rows. Runoff from the esfenvalerate-sprayed orchard section was less toxic to waterflea than runoff from the diazinon-sprayed section. However, runoff from the orchard section sprayed with esfenvalerate was highly toxic to fish larvae. Samples collected from both sections one month later were not toxic to fish, but remained highly toxic to invertebrates. The ground cover crops reduced total pesticide loading in runoff by approximately 50%. No differences were found between the types of vegetation used as ground covers.
