Poison

A study tested bones from throughout human history to check the levels of lead concentration in different eras.

The highly dangerous herbicide, Doctlon, which is outlawed for use in public areas, was sprayed on park grounds, according to the complaint.

Russia's prison service said Navalny, 44, was in a "satisfactory" state and he was being given "vitamin therapy" with his consent.

Dual narratives don’t always work – I often find myself much more interested in one and rushing through the other. But Penner keeps both parts of The Lost Apothecary engrossing.

The officials said Navalny was targeted for his activism in trying to raise questions about what they called Russian corruption.

Many Western countries say Navalny was poisoned with a nerve agent, but the Kremlin has denied any role in his illness and has said it has seen no proof that he was poisoned.

Ironically, the poison was stored in a can used for baby formula and forgotten in an area of the kindergarten where toddlers usually roam around and play freely.

"Initial reports indicate soldiers consumed this substance, thinking they were drinking an alcoholic beverage," the Army statement added.

It was not immediately clear why he had been detained.

Navalny said his own investigators had checked the findings and that the case was now solved despite the absence of an official investigation in Russia.
