2.ZT:

In 1988, the World Health Organization set a Provisional Tolerable Weekly Intake (PTWI) of 15ug (mcg) per kilogram (kg) of body weight for inorganic arsenic. For a person weighing 50kg (110lbs.) this equals 107ug (mcg)/per person/per day. The FSA study results for hijiki showed a maximum inorganic arsenic level of 22.7mg/kg in soaked hijiki. Based on these figures, even if this hijiki was consumed, the PTWI would not be exceeded unless a person was consuming 4.7g daily over an extended period of time.

The FDA tolerable daily intake is 130ug (mcg) per day. The EPA however, based on high levels of arsenic in water sample from Taiwan, India and Bangladesh is 0.0003mg/kg/day or 15ug (mcg) per day for a person weighing 50kg.
