Chlorophenols have been widely used for a variety of pesticidal applications. Chlorophenols and their sodium salts have been primarily used for wood preservation and as chemical intermediates in the manufacture of other pesticides or chemicals. In China, sodium pentachlorophenate (Na-PCP) was especially used to eradicate snails, Oncomelania hupensis, in the schistosomiasis area in China. Chinese commercial PCP or Na-PCP contained appreciable amounts of PCDD/Fs, and their concentrations in PCP and Na-PCP were 142 and 92 ng I-TEQ g-1, respectively (Bao et al., 1995). 

Molluscicidal activity against the snails Oncomelania hupensis and Biomphalaria glabraU 113... 

The control of the aquatic snails such as Biomphalaria gtabraia and Bulinus trancatus have been frequently studied in European, African and South-American countries. But in China, this endemic disease is caused by the amphibious snail Oncomelania hupensis. To kill this kind of snail, the molluscicides should not only toxic to it, but also have the abilities to prevent it from up-crawling out of the water while the molluscicides take effect.
