So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.

那么，在这种情况下，我们看到氮的形式电荷是负的，而在这种情况下，氧的是负的。

So what we see is that the formal charge on the nitrogen is 0.

因此我们看到氮的形式电荷是零。

So in our first structure, we would find for the nitrogen we have a formal charge 5 minus 4 minus 2, because we're starting with 5 valence electrons, so that is a formal charge of minus 1.

那么在我们的第一个结构中，我们发现氮的形式电荷量是五减去四4,再减去二，因为我们开始有五个价电子，因此它的形式电荷量是负一。

The report also says that the congestion charge has caused reductions in the two most concerning pollutants to London, by 8% for nitrogen oxides and 7% for particulate matter that is fine enough to penetrate the lungs and cause health problems (referred to as PM10).
