Effects of treatment with sodium fluoride and subsequent starvation on fluoride content of earthworms



Effects of treatment with sodium fluoride and subsequent starvation on fluoride content of earthworms



Bulletin of Environmental Contamination and Toxicology 38.1: 163-170



Two experiments were made: to expose earthworms kept in soil to different concentrations of sodium fluoride; to measure resulting fluoride in earthworms when soil was removed from their gut by starvation for varying periods of time; and to compare amounts of fluoride in whole starved earthworms with those in starved earthworms from which remaining soil had also been physically removed by dissections and washing.As the number of days of starvation increased, the mean concentration of fluoride in all worm samples decreased significantly. Treated cleaned worms had more than 6 times the amount of fluoride found in untreated cleaned samples. This indicates that earthworms may have elevated amounts of fluoride in their tissues, as well as in their gut contents.
