<reasoning>

Compare units of concentration

Convert the units to a common scale to compare them directly:
\[

$$\begin{aligned} 1\text{ ppm} &= 1000\text{ ppb}\\ 0.05\text{ ppm} &= 50\text{ ppb}\\ 0.10\text{ ppm} &= 100\text{ ppb} \end{aligned}$$

\]

Compare all values in ppb

List all concentrations in parts per billion (ppb):
\[

$$\begin{aligned} 0.05\text{ ppm} &= 50\text{ ppb}\\ 0.05\text{ ppb} &= 0.05\text{ ppb}\\ 0.10\text{ ppm} &= 100\text{ ppb}\\ 0.10\text{ ppb} &= 0.10\text{ ppb} \end{aligned}$$

\]

Identify the highest concentration

Compare the converted values:
\[
100\text{ ppb} > 50\text{ ppb} > 0.10\text{ ppb} > 0.05\text{ ppb}
\]
The highest concentration is \(0.10\text{ ppm}\).
