INTRODUCTION

This appendix is intended for use in conjunction with the 2001 Annual Air Quality in Ontario report. The first section of the Appendix briefly describes the provincial air monitoring network, quality assurance and quality control procedures and the Ministry of the Environment air quality database. The second part of the Appendix includes a series of tables displaying station locations and a listing of the summary statistics including means, maxima, percentile values and the number of exceedances of the Ontario ambient air quality criteria for each pollutant.

MONITORING NETWORK OPERATIONS

Network Description

In 1971, the provincial air monitoring network consisted of 254 instruments. Of those, 166 were continuous analyzers located at 76 monitoring sites and 88 sites were with high-volume samplers. By 1980, the provincial network had reached its maximum size of 450 instruments of which 268 were continuous analyzers located at 106 sites and 182 high-volume samplers. In 2001 the network comprised of 236 continuous monitoring instruments at 80 sites, 50 high-volume samplers, 27 daily PM₁₀ samplers and 39 real-time PM_10/2.5 monitors.

Over 50 per cent of all air monitoring performed by the ministry is source-specific. The Operations Division of the Ministry of the Environment was primarily responsible for the operation of these sites in 2001. For the most part, the operation of the monitoring stations and the collection of air samples is conducted by the regional staff.

During 2001, the Environmental Monitoring and Reporting Branch operated the Greater Toronto Area ambient stations and the mobile air monitoring units. The monitoring networks are classified by their functions: continuous air monitoring; noncontinuous sampling; meteorological; and mobile air monitoring.

Ministry regional boundaries and the locations of air monitoring sites of continuous, noncontinuous and meteorological networks are illustrated in Maps 1-3.

Quality Assurance and Quality Control

Day to day air monitoring and maintenance of the instruments is administered by staff of the Environmental Monitoring and Reporting Branch and staff of the Operations Division. Air monitoring technicians audit the instruments on a daily basis, by using a computerized telephone link to confirm the automatic zero and span values - a known value for a particular gas.

The air monitoring technicians consistently inspect and maintain monitoring equipment and stations. Should an instrument undergo major servicing, the Instrumentation and Quality Assurance Unit will conduct a re-calibration of the instrument. Portable calibration equipment is used by regional staff and is re-calibrated at least twice per year.

Other monitoring programs, such as those operated by the Sarnia-Lambton Environmental Association, Environment Canada and Ontario Power Generation, collaborate with the ministry in auditing procedures and comparative activities. Data from these programs and provincial monitoring sites are used to determine the status of provincial air quality.

The Environmental Monitoring and Reporting Branch operates a laboratory with gas reference standards that adhere to those of the U.S. National Institute of Standards and Technology (NIST) and the Pollution Measurement Division of Environment Canada. Performance audits are conducted on the sulphur dioxide, nitrogen oxides/nitrogen dioxide, ozone and total reduced sulphur (as hydrogen sulphide) monitors approximately three times per year. Performance audits are conducted twice a year for PM_10/2.5 monitors and once a year on carbon monoxide monitors. Chemical analyses performed by the Laboratory Services Branch are also subject to quality assurance and control.

The Ontario ambient air quality monitoring network undergoes constant maintenance to ensure a high standard of quality control. Continuous real-time and particulate data are consistently reviewed, assessed, and validated by regional staff and staff of the Environmental Monitoring and Reporting Branch. Immediate actions are taken to correct any inconsistencies that may affect the validity of the data. These measures ensure ambient air monitoring data are valid, complete, comparable, representative and accurate.

In 2001, continuous air monitoring instruments were given 719 performance audits. Approximately 90.2 per cent of the audits were found to be consistent with the acceptable performance criterion, i.e. measured values were within 10 per cent of the standard. For the remaining 9.8 per cent, which fell outside the 10 per cent range, station log records and backup charts were consulted to adjust the data to reflect true ambient concentrations. As a result, the continuous network for 2001 had 92 per cent valid data from over 3 million data points.

Data Base

The ambient air quality data used in this report are stored in the ministry’s air quality information system (AQUIS). Over 3 million air pollution measurements are added to AQUIS annually, with the vast majority representing Ontario’s more heavily populated urban areas.

A statistical pattern test is used to identify data anomalies, such as unusual pollutant concentrations. Each pollutant has a predetermined concentration range based on historical data. Values outside this range are flagged for further investigation.

AQUIS data are divided into two major groupings: continuous (1-hour) measurements and daily (24-hour) measurements. Hourly data are obtained from automated ambient air monitoring instruments that operate continuously. These produce an average measurement for every hour for a possible total of 8760 measurements in a given year. Hourly parameters measured include O₃, PM_2.5, PM₁₀, SP (measured as COH), NO/NO₂/ NOx, CO, SO₂, TRS compounds and Hg. A valid annual mean requires at least 5840 hourly readings or 67 per cent valid data. The network typically yields approximately 92 per cent valid data.

The instruments that provide daily measurements from a 24-hour sampling period are usually operated on three or six-day sampling cycles. They measure TSP, PM₁₀, lead (Pb), various trace metals, sulphate (SO₄^2-) and nitrate (NO₃-). Daily data requires a valid annual mean to be at least two thirds of the total number of possible samples, i.e., a station operating on a 6-day sampling schedule would require at least 40 out of a possible 61 samples.

To be included in the 10-year trend analysis, a site must have valid annual means for a minimum of 8 years in the 10-year period from 1992-2001.

NETWORK DESCRIPTIVE TABLES AND ANNUAL STATISTICS

The complete continuous (hourly) network is summarized in Table 1 and Map 1. The table displays the station name, numerical identifier, and pollutants measured. The numerical identifier is the station (ID) number, the first digit of which identifies the geographic region in which the station is located.

The column headings for the continuous pollutants are as follows:

O₃ (ozone)
PM_2.5 (real-time fine particulate matter)
PM₁₀ (real-time inhalable particles)
SP (suspended particles as measured by the Coefficient of Haze)
NO (nitric oxide)
NO₂ (nitrogen dioxide)
NOx (oxides of nitrogen)
CO (carbon monoxide)
SO₂ (sulphur dioxide)
TRS (total reduced sulphur compounds)
Hg (mercury)
AQI (air quality index)

The particulate (daily) network is summarized in Table 2 and Map 2. The table displays the station name, numerical identifier, and pollutants measured. Numerals indicate the monitoring cycle frequency in days. The column headings for the noncontinuous pollutants are as follows:

TSP (total suspended particles)
Cd (cadmium in TSP)
Cr (chromium in TSP)
Cu (copper in TSP)
Fe (iron in TSP)
Mn (manganese in TSP)
Ni (nickel in TSP)
Pb (lead in TSP)
V (vanadium in TSP)
NO₃- (nitrate in TSP)
SO₄^2- (sulphate in TSP)
Cl - (chlorine in TSP)
C (carbon in TSP)

The 24-hour inhalable particle (PM₁₀) network is summarized in Table 3. This table displays the station location, parameters measured and frequency of sampling.

The meteorological network is summarized in Table 4 and Map 3. This table displays the station name, numerical identifier, meteorological parameters measured and the height of the measurements.

The 2001 statistical data for various pollutants are provided in Tables 5 through 15 and Tables 25 to 55. The stations used in the 10-year trends are listed in Table 16 and the 10-year trends are presented in Tables 17-24.
