Determination of chlorophacinone and diphenadione residues in biological materials

Diphenadione residues in milk of cattle

“…Residue Analysis. A gas-liquid chromatographic (GLC) procedure reported earlier in this journal was used for analysis of all milk and blood samples (Bullard et al, 1975). The only difference in analysis of milk and blood is in the sample preparation.…”

Superwarfarins

“…An early, interesting approach was to use a post-column pH shift to enhance fluorescence detection (Hunter, 1983(Hunter, , 1985. Several earlier HPLC methods have also been reported (AOAC, 1976a,b;Mundy and Machin, 1982;Hunter, 1983): diphacinone (Bullard et al, 1975(Bullard et al, , 1976, fluorescence for bromadiolone (Deepa and Mishra, 2005), brodifacoum (Fu et al, 2006), brodifacoum in tissues (Hoogenboom and Rammell, 1983), difenacoum (Hadler and Shadbolt, 1975), determination of Rozol in parafinized formulations (Kawano and Chang, 1980), and bromadiolone in tissues (Nahas, 1986).…”

Rats! Foiled Again: A History of Rodent Control Methods Development at the National Wildlife Research Center

“…Important papers include Johns and Thompson (1979), Kimball and Mishalanie (1993), Johnston et al (1995), Mauldin et al (1996), Johnston et al (1997), Goldade et al (1998), andMauldin et al (1999). As equipment and technology for chemical analyses continued to improve, the need for such information also continued to increase -particularly for pesticide registration and other regulatory purposes related to environmental exposure and human or animal safety (Bullard et al 1975, Bruggers et al 1995, Goodall et al1998). Increasingly, analytical chemistry techniques have also been applied to other investigations, particularly those involving development of attractants, repellents, and marking agents, and more recently, risk assessments (Johnston et al 2005, Arjo et al 2006, Johnston 2007.…”
