The manganese of jug of stainless steel electric heat is not terrible, but how should choose eligible goods?

Manganese is a kind of microelement of human body demand, but wait other nutrient element a moment with calcic, magnesian, natrium identical, cannot the more the better. We are pondering over the time of the intake of manganese, demand consults two numerical value, recommend intake RNI, and can be able to bear or endure suffer intake UL. Little show at RNI nutrient is lacked, over UL means excessive, demand ponders over danger. The manganese that China suggests is daily RNI, arrive from 1 year old adult, it is 1.5 milligram differ to 4.5 milligram respectively, UL is 3.5 milligram to 11 milligram.

Manganese oneself also is element of a kind of nutrient, the index of sanitation of stainless steel goods that place of electric jug commodity uses checks a standard in, did not prohibit restraining the regulation of manganese probably. Stainless steel commodity, those who take seriously is these bigger to human body harm material separate out measures lead, cadmium, chromium, nickel, arsenic, in be checked this, quantities of these toxic substance separate out check gain all eligible.

Compare with these corporeal appearances, manganese not so hate by the person, consequently China is mixed Euramerican wait for most country to be done not have about separate out of stainless steel manganese the quantity undertakes limitative, also did not appoint the method of relevant examination naturally. Because do not have off-the-peg regulation, what Jiangsu uses this is the method that a kind of other person indissolubles, with the second acid of 4% (acetic acid) will immerse, boil, next quantity of measure separate out. If this of the examination is stainless steel stewpan, fry pan this kind also calculated, but we buy hot water bottle is not to boil vinegar, heat boiling water, heat plain boiled water however, qualitative inspect part is used so a kind of method will determine the quantity of manganese separate out of electric heat jug lets a person indissoluble really.

About so doubt, jiangsu pledges the response of inspect part is this is to use " more severe measure " will undertake checking to potential risk, the achievement of that examination how? Allegation did not give out detailed number, the amount of manganese separate out that says jug of electric heat of tall manganese steel merely is 0.1-1.168 milligram / rise. Since do not have standard of manganese separate out, do not have method differentiate naturally this is eligible. The daily intake that nevertheless we had mentioned manganese above connection UL, so so called potential risk is very clear: The pitcher of electric heat of tall manganese steel that if an adult was drunk one day,uses 10 litres almost boils the holiday the vinegar that come out, so with respect to the likelihood manganese overspent.

Whole thing is received go down to become humorrer, be faced with doubt to be criticized probably, part of Jiangsu qualitative inspect has a pair only " intention fine suffers from nobody to know " expression. And actually, all " manganese is toxic " state business, already was close to now actually at a farce. Because true manganese is toxic thing, common at manganese mine worker, welder person this is planted the can inspiratory soot that contain manganese this kind of setting, be in at ordinary times on food safety, manganese is toxic not be what " potential risk " .
