An example is 1,1,1-trichloroethane (methyl chloroform) that had a single-pollutant odds ratio for an ASD diagnosis of 1.88 (95% CI: 1.04, 3.38), which was attenuated to 0.55 (95% CI: 0.22, 1.37) adjusting for benzidine, to 0.83 (95% CI: 0.32, 2.14) adjusting for mercury compounds, and to 1.23 (95% CI: 0.48, 3.17) adjusting for pentachloronitrobenzene. Another example is diesel particulate matter that had an odds ratio with ASD diagnosis of 1.44 (95% CI: 1.06, 1.97), which was attenuated to 1.06 (95% CI: 0.73, 1.55) adjusting for propionaldehyde.
The SS was 1-bromo-2-nitrobenzene (OCP-SS), and the IS was pentachloronitrobenzene (OCP-IS).
PCA is a degradation product of pentachlorophenol (PCP) and pentachloronitrobenzene (PCNB) which is a prominent OCP in arctic air (Su et al.
1 medium for actinomycetes, and Martin's Rose Bengal medium for fungi (Martin, 1950), and an improved selective medium (K2HPO4 1 g, KCl 0.5 g, MgSO4 0.5 g, Na-EDTA 0.01 g, pentachloronitrobenzene 0.05 g, L-asparagine 2 g, bile salt from ox 0.5 g, L-sorbose 2 g, sodium tetraborate 1 g, dH2O 1000 mL, pH 5.4, and 1% streptomycin stock solution 0.3 mL after autoclaving sterilization when the mixture cooled to 55degC) for V.
Microbiologic labour consisted in shredding solid samples into about 25 [mm.sup.2] pieces of dead organic materials, then plating them on modified and V8 medium, to which we added Ampicillin, Nystatin, Pimaricyn, Rifampicyn and Pentachloronitrobenzene.
After three days, the fruit with lesions was removed from the ground and washed in tap water, proceeding to the isolation on PDA medium (potato dextrose agar), supplemented with Nystatin, PCNB (pentachloronitrobenzene), carbendazin (replacing the benomyl), rifampicin and ampicillin (MASAGO et al., 1977).
Isolation and pathogenicity: Isolations of the pathogen was made on common medium (Potato Dextrose Agar), selective medium (Peptone Pentachloronitrobenzene Agar) and natural medium (Spezieller Nahrstoffarmer Agar, Carnation Leaf Agar) for fungal culture (Zainudin et al., 2008a; Dal Pra et al., 2010).
Examples include nitrobenzene, 1,3-dinitrobenzene (1,3-DNB), 1,3,5-trinitrobenzene (1,3,5-TNB), 2-chloronitrobenzene (2CNB), 3-chloronitrobenzene (3CNB), 4-chloronitrobenzene (4CNB), and pentachloronitrobenzene (PCNB) (Figure 1).
then, 100 ng of each of the internal standards (2-fluoro-1,10-biphenyl and [p-terphenyl-d.sub.14] for PAHs, 4,4'-dichlorobiphenyl for OCPs, pentachloronitrobenzene for PCBs, and [C.sup.13]-PCB208 for PBDEs) was added to the GC bottle.
Bark pieces, about 2-4mm-wide, were cut from the edge of the lesions and placed on cornmeal agar (CMA) (Sigma-Aldrich Chemie GmbH, Germany) amended with 10mg pimaricin, 200mg ampicilin, 10mg rifampicin, 10mg benomyl, 25mg pentachloronitrobenzene and 50mg hymexazol (PARBPH) [8].
Agricultural company American Vanguard Corporation (NYSE:AVD) reported on Wednesday the receipt of approval for certain registrations for its pentachloronitrobenzene (PCNB) product line for all major commercial uses in the US.
