Metrics, Targets and Monitoring Protocol

What is measured?

Concentrations of particulate matter, SO2, F, and PAH at established monitoring stations in Reydarfjordur (µg/m3). (Project effect: indirect).

Monitoring Protocol

Ambient air monitors, and precipitation monitor for both rain and snow.

  • Information will be collected with an annual "significant measurement" (EOL)
  • Measurements of SO2 and gaseous fluoride performed continuously, weekly for dust.
Target
  • Dust: < 50mg/Nm3 (EOP)
  • SO2: Yearly average concentration < 20 µg/m3 (EOP)
  • Gaseous F: average 0.3 mg/m3 from 1 April to 30 September each year. Possibly 0.2 mg/m3 after 48 months of operation (EOP).
Possible countermeasures

Alcoa Fjarðaál and Landsvirkjun have enviromental policies that are set to respect the environment.

Changes of indicator

This indicator was originally number 17.2. It was then named Air Emissions and can be found under that number in documents of the project from 2005 and 2006.

The indicator number has been changed twice.

Year Nr. Indicator name
2020 2.3.2 Suspended particulates
2007 2.14b Air Quality

Baseline

Concentration of airborne dust, SO2, F and PAHs at selected monitoring stations in Reyðarfjörður (μg/m3):

In the tables below you can see the results of measurements of the concentration of dust particles, SO2 and fluorine at selected monitoring sites in Reyðarfjörður in the years 2005 - 2008. Newer results will be included in the section on results as soon as they are ready.

Rationale for Indicator Selection

Air quality is an important human health issue. Local residents are concerned that the smelter will adversely affect the local air quality and detract from the quality of life in Reydarfjordur. The sustainability of the local communities is, in part, dependent on desirable living conditions and the quality of the local environment. Emissions from the smelter will have a direct effect on the air quality in East Iceland.
