Sulphur Dioxide MADL Raised to 10,0000 microgram/day

Posted in Agricultural Law, Prop 65

The MADL (maximum allowable dose) for sulphur dioxide has been raised by OEHHA from 220 micrograms per day to 10,000 micrograms per day, based on a calculation error in the original document relied upon by the state.     That error  was discovered by the Grocery Manufacturers Association (“GMA”). Thus OEHHA concluded that a 1989 study on mice is actually the most sensitive acceptable study and it calculates the MADL from that study resulting in a new proposed MADL of 10,000 micrograms per day. The change means that higher levels of exposures to SO2 will fall within the safe harbor and will not be subject to the Proposition 65 warning requirement.
