Nitrogen dioxide (NO2) is a gas that is harmful to human health, ecosystems, and plants (US EPA, 2008). It can be emitted directly into the air but is often formed as a secondary pollutant when nitric oxide (NO) emissions react with other chemicals. It also contributes to the formation of secondary particulate matter (PM) and ozone, which have their own health impacts. In New Zealand, motor vehicles are the main human-made source of nitrogen oxides (NOx), the collective term for NO2 and NO. Because nitrogen dioxide concentrations are closely associated with vehicle emissions, it can be used as a proxy for other motor-vehicle pollutants such as benzene, carbon dioxide, and carbon monoxide.
Human exposure to high nitrogen dioxide concentrations causes inflammation of the airways and respiratory problems, particularly asthma. Nitrogen dioxide causes leaf injury in plants exposed to high levels. It also contributes to forming secondary particulate matter and ozone, which have their own health impacts.
We report on observed nitrogen dioxide concentrations from 13 regional council and unitary authority monitoring sites. Council and unitary authority data are measured using regulatory-compliant monitors that can be directly compared with health guidelines.

Black carbon is a particle, often in the PM2.5 or ultra-fine size range, which is emitted from combustion sources and is commonly known as soot. In New Zealand most black carbon is emitted from vehicles (especially diesel vehicles), burning wood and coal for home heating, and outdoor burning. Both long and short-term exposure to black carbon is linked to serious health effects, such as respiratory and cardiovascular disease, cancer, and premature death (World Health Organization (WHO), 2013).
Black carbon warms the climate globally and regionally because it is efficient at absorbing energy from sunlight. Black carbon also increases ice and snow melt when deposited on these surfaces, darkening them and lowering albedo (proportion of light that is reflected) so they absorb more solar energy (Ramanathan & Carmichael, 2008).

Inhaling particulate matter (PM) containing heavy metals can cause serious health effects (World Health Organization (WHO), 2013). Airborne arsenic is linked to lung cancers (WHO, 2013), and heart, liver, kidney, and nerve damage (Caussy, 2003). Nickel and vanadium are linked to lung and nasal sinus cancers. Lead can impair cognitive function in children and affect an adult’s cardiovascular system, even at low blood levels (WHO, 2013).
Heavy metals are also toxic to other organisms, and can bioaccumulate in animals, especially in aquatic ecosystems (Rahman, Hasegawa, & Lim, 2012). We don’t know how much airborne heavy metal is deposited in New Zealand.
We report on the concentrations of arsenic, lead, and vanadium in PM10 (PM 10 micrometres or less in diameter) from 2007-16 at Henderson – Auckland which were measured using a method directly comparable to relevant guidelines. We also report on arsenic, nickel, lead, and vanadium concentrations at 5 Auckland sites from 2005–16 that were measured using a method which cannot be directly compared to relevant guidelines but provides information on concentrations.
Arsenic is emitted when burning wood treated with copper chromium arsenic preservative (eg building project offcuts). A 2012 Auckland study showed that 17 percent of households may burn such wood (Stones-Havas, 2014).
Lead is emitted from burning wood coated with lead-based paint, by removing lead-based paint from buildings without proper safety precautions, and from industrial discharges (eg at metal smelters). In New Zealand, airborne nickel and vanadium concentrations are highest near ports and are associated with combustion exhaust from ships (Davy & Trompetter, 2018). Monitoring for lead has been limited since the fall in ambient lead concentrations after New Zealand’s petrol became lead free in 1996.

Carbon monoxide (CO) is a gas formed by the incomplete combustion of fuels, particularly from motor vehicles, from burning wood and coal, and using unflued gas heaters for home heating. It also occurs naturally; for example, from wild fires.
Carbon monoxide can affect human health by interfering with the blood’s ability to carry oxygen and by aggravating heart conditions. It has a relatively long life in the atmosphere – about three months. This is due to the slow rate at which carbon monoxide oxidises, forming carbon dioxide (a greenhouse gas). Carbon monoxide also has an important role in forming smog.

Particulate matter (PM) comprises solid and liquid particles in the air. PM10 particles have a diameter less than 10 micrometres. Coarse particles (2.5–10 micrometres) can be inhaled – they generally deposit in the upper airways; fine particles (smaller than 2.5 micrometres) can deposit deep in the lungs where air-gas exchange occurs. Children, the elderly, and people with existing heart or lung issues have a higher risk of health problems from exposure to PM10. These problems include decreased lung function, heart attack, and mortality.
Human-generated PM10 sources include burning wood and coal for home heating, and traffic emissions (eg combustion, tyre and brake wear, and pavement breakdown). Natural sources include sea salt, dust, pollen, and mould spores.

PM2.5 is made up of solid and liquid particles in the air with a diameter of less than 2.5 micrometres. In New Zealand, most PM2.5 in the air results from combustion (burning wood for home heating, motor-vehicle exhaust), and to a lesser extent, particles formed from reactions in the atmosphere (secondary PM) and naturally occurring sea salt.
Short- and long-term exposure to PM2.5, even at low levels, is linked to respiratory and cardiovascular disease, and increased risk of premature death, especially in vulnerable people (the young, the elderly, and people with respiratory illness). Emerging evidence points to possible links with cognitive function, neuro-development, and diabetes.

Benzene is a volatile organic compound (VOC) that is common in the air. Motor vehicles are benzene’s primary emission source (Guerreiro, Foltescu, & de Leeuw, 2014; Weisel, 2010) although burning wood or coal for home heating, volcanoes, and forest fires also emit benzene.
Benzene is a human carcinogen (World Health Organization Regional Office for Europe Copenhagen, 2000) that has been shown to cause leukaemia (Smith, 2010), and is associated with developmental, immune, neurological, reproductive, and respiratory problems (Bahadar, Mostafalou, & Abdollahi, 2014). Acute exposure can affect the liver and respiration (Bahadar et al, 2014).
