Documenting that the potential exposure to total estrogens (prescribed and naturally occurring) in drinking water is at least 82 times lower than our natural background dietary exposure suggests that exposures to estrogens (prescribed or naturally occurring) in drinking water are inconsequential and should have no effect.
It also found levels of radium up to 90 times higher than those naturally occurring in drinking water.
Radiation exposure through drinking water results from naturally occurring radionuclides in drinking water sources, in particular alpha-radiation emitting uralpha-radiation emitting progeny, incluraniumadon.
The occurrence of naturally occurring radionuclides in drinking water can pose health hazards in some populations, especially taking into account that routine procedures in Drinking Water Treatment Plants (DWTPs) are normally unable to remove them efficiently from drinking water.
LONDON, Aug. 29 (Reuters) — Naturally occurring arsenic in drinking water poses a growing global health risk as large numbers of people unknowingly consume unsafe levels, researchers said on Wednesday.
