After my previous post, I checked out “how it is in Russia.” A document on threshold values for pollutants in food products.
I don’t really understand this well, and if anyone knows better—please correct me. But here’s what I see: for canned foods in tin containers—including condensed milk—the indicated threshold value for tin is 200 mg/kg, which is a lot; there should essentially be none when unpackaged. Indeed, the same canned foods not in tin containers won’t contain tin.
For tea, the tolerance for lead is 10 mg/kg and for copper—100 mg/kg. Additionally, according to the document, it may contain Escherichia coli, cesium-137 (400 Bq/kg), and strontium-90 (200 Bq/kg).
The threshold for zinc in egg powder is 200 mg/kg. The highest mercury levels are found in kidneys and their by-products, and also in the same egg powder. The most arsenic is found in spices and condiments—up to 1 mg/kg.
Interestingly, the highest permissible figures for nitrates are assigned to table beets (1400) and leafy vegetables (2000) – compare that to watermelons, for instance, which have just 60.
Various mollusks and crustaceans are rich in lead. And quite significantly so (10 mg/kg)—compare this with meat (0.5 mg/kg).
No conclusions here, as I’m not an expert. If anyone can provide them—I’d appreciate it 🙂
There’s a lot that can be extracted from the document, just requires more than a casual five-minute analysis like mine.
