The hydrolysis of some methylphosphonites and methylphosphinates was studied in the pH range 4.5–7.5 by phosphorus-31 nuclear magnetic resonance spectrometry. For methylphosphonites, a two-step reaction mechanism was observed in which formation of

A procedure has been developed in which the presence of PCH3-containing compounds in surface waters can be detected in a sensitive and specific way. The compounds of interest are hydrolysed, yielding methylphosphonic acid as a common breakdown produc

The concentration of PCH3-containing compounds was determined in several surface water samples obtained from a number of countries in Western Europe and North-America. A correlation was found between this concentration and the grade of water pollutio
