One of the biggest challenges that chemists face is knowing what impact their synthesis is going to have on the environment.
0:24 → 0:32
Monitoring a process on a small scale to see what pollution is produced at a particular stage of a reaction
0:32 → 0:37
can reduce the pollution that's produces in the large scale synthesis.

Can you think how?

An answer might be that looking at the pollution produce on a small scale and in real time,
0:49 → 0:56
will enable chemists to know where they have to change in their large scale synthesis,
0:56 → 1:00
to ensure their practices have a lower environmental impact.
