I saw this today:
Less than two months after federal food regulators said they were unable to set a safety threshold for the industrial chemical melamine in baby formula, they announced a standard that allows for higher levels than those found in U.S.-made batches of the product.
Food and Drug Administration officials on Friday set a threshold of 1 part per million of melamine in formula, provided a related chemical isn’t present. They insisted the formulas are safe.
The setting of the standard comes days after The Associated Press reported that FDA tests found traces of melamine in the infant formula of one major U.S. manufacturer and cyanuric acid, a chemical relative, in the formula of a second major maker. The contaminated samples, which both measured at levels below the new standard, were analyzed several weeks ago.
So, I looked up melamine on the inner-tubes thingy. Here is what melamine is normally used for:
Melamine is combined with formaldehyde to produce melamine resin, a very durable thermosetting plastic used in Formica, and melamine foam, a polymeric cleaning product. The end products include countertops, dry erase boards, fabrics, glues, housewares and flame retardants. Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.
Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticizer for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength exhibiting an improved resistance to aggressive environments and a longer life-time.
The use of melamine as fertilizer for crops had been envisaged during the ‘50s and ‘60s because of its high nitrogen content (2/3)[7]. However, the hydrolysis reactions of melamine leading to the nitrogen mineralisation in soils are very slow, precluding a broad use of melamine as fertilizing agent.
Nice, huh?
