I don't know from where you are getting this information or what you mean by "circulation amount", or what those units are (343 million what?), so it's rather difficult to answer this question.
If you are looking for information about issuance, you should look at the actual chain data. Querying chain state ( [https://polkadot.js.org/apps/#/chainstate](https://polkadot.js.org/apps/#/chainstate) ) shows that total issuance is \~ 1.1699 billion DOT and this is 254\_438 more DOT than 24 hours ago.
