The process of horizontal air pollutant transport is generally referred to as Advection.

Here's a step-by-step explanation:

1. Convection: This is the process of heat transfer through a gas or liquid by bulk motion. It's not specific to horizontal movement and doesn't necessarily involve pollutants.

2. Advection: This is the process of transport of a substance or quantity by bulk motion. The substance can be any concentration of chemical species, pollutants, or even energy. In the context of air pollution, when pollutants are transported horizontally by the wind, this is referred to as advection.

3. Inversion: This is a term used in meteorology to describe a situation where temperature increases with height, which is the opposite of what usually happens in the atmosphere. It doesn't refer to the transport of pollutants.

4. Aversion: This is not a term used in the context of air pollution or atmospheric science. It generally means a strong dislike or disinclination.

So, the correct answer is Advection.
