Isopropylmethylphosphonic acid

Environment. Detection of environmental degradation products of nerve agents directly from the surface of plant leaves using static secondary ion mass spectrometry (sims) has been demonstrated (97). Pinacolylmethylphosphonic acid (PMPA), isopropylmethylphosphonic acid (IMPA), and ethylmethylphosphonic acid (EMPA) were spiked from aqueous samples onto philodendron leaves prior to analysis by static sims. The minimum detection limits on philodendron leaves were estimated to be between 40 and 0.4 ng/mm for PMPA and IMPA and between 40 and 4 ng/mm for EMPA. Sims analyses of IMPA adsorbed on 10 different crop leaves were also performed in order to investigate general apphcabiflty of static sims for... 

Of topical interest is the investigation of Vermillion and Crenshaw [146] on the analysis of nerve gas degradation products in soil samples. They investigated isopropylmethylphosphonic acid (IMPA) and methylphosphonic acid (MPA) that are formed via hydrolysis of GB (sarin) under environmental conditions (Figure 10.64). In the vicinity of former production sites and future incineration plants, these two components pose a potential environmental risk, so a simple...
