Update term "resp_part_matter" [MIXS:0000108] to "air_PM_concen"

[only1chunts]

Proposed term details The following term is proposed in the Food package:

Term name - air particulate matter concentration
Structured comment name - air_PM_concen
Definition - Concentration (micrograms per cubic meter) of fine solid or liquid particles carried by the air, including particulate matter size fraction. Multiple terms can be separated by pipes.
Expected value - enumeration; measurement value
Value syntax - [PM 0.1|PM 10|PM 2.5]; {measurement value}
Example - PM 0.1; 37 micrograms per cubic meter
Term ID - MIXS:0001112
Package(s) - Food

Suggested update(s) There is already an existing term that is very similar:

Term name - respirable particulate matter 
Term ID - MIXS:0000108
Structured comment name - resp_part_matter
Definition - Concentration of substances that remain suspended in the air, and comprise mixtures of organic and inorganic substances (PM10 and PM2.5); can report multiple PM's by entering numeric values preceded by name of PM
Expected value - particulate matter name;measurement value  
Value syntax - {text};{float} {unit}
Example - PM2.5;10 microgram per cubic meter
Preferred unit - microgram per cubic meter
Package(s) - Air

Additional context Are these terms the same? if so we do not need the new one (air_PM_concen) in the food packages

This term is proposed in the 147 new terms ticket #201

Looks like the two terms could be merged. Lynn

Seems same, we could harmonize the definitions

Use existing terms, but use label from food package (air particulate matter concentration) which is neutral to whether or not you are breathing it.

We are NOT creating the new term MIXS:0001112 for the food package, instead, we will update the existing terms and use that.
