Title

Glastir Woodland Creation - Scoring Layer - Air Quality

Abstract

This data layer was compiled by the National Atmospheric Emissions Inventory (NAEI) and uses 1km grid squares of point source data, as well as road transport data. These inputs are compiled, averaged, and mapped across the UK, and are then split by source category and further split by pollutant. The specific layer used in this project is ‘Total emissions <PM10’, which contains emissions from 2012 using CORINAIR SNAP sensors and measures pollutants in particulate matter of less than 10µm.

Sources of PM10 in the UK include road traffic, industry and power production. Results from numerous investigations of human respiratory and other diseases show consistent statistical associations between human exposure to outdoor levels of PM10 and adverse health impacts. Vegetation intercepts airborne particulate matter (PM10), reducing concentrations in the air, thereby improving air quality. This reduces the amount of PM10 exposure to humans and, in turn, can reduce the incidence of respiratory illness.
