The air near the Port of Stockton already fails to meet state and federal regulations on particulate matter made up of soot, metals, construction dust and smoke.

For particulate matter, the team measured peak concentrations in micrograms per cubic metre of air.

Mega-dairies are among the largest ammonia emitters, contributing to fine particulate matter pollution that causes respiratory illnesses and premature death.

They found that the new footpaths encouraged 9% to 27% of the surveyed respondents to walk instead of using motorized transport, which led to a reduction in greenhouse gases and particulate matter.

In this, the researchers show that measures to combat slash-and-burn techniques significantly reduce the concentration of particulate matter in the air.
