In addition to measuring the air contaminants, the effect of weather will also be taken into account as it has a profound influence on contaminant dispersion and concentrations. Monitoring organizations in countries such as New Zealand suggest that meteorological effects such as temperature inversions can dramatically increase contaminant levels. Moreover, it would not be possible to gain a clear picture of the air quality in an area without meteorological monitoring, hence, this study will also take some basic meteorological monitoring such as temperature, humidity and pressure at the air quality monitoring sites. The meteorology effect may prove very useful, especially when trying to assess the validity of data. 
To ensure that accurate and credible air quality data is obtained from this study, the use of an equipment with high-precision instrumental methods is required in order to understand the ways in which contaminant levels fluctuate over short time periods (hours or days). One of the latest equipment to have such capabilities is the VAISALA Air Quality transmitter (AQT) 400 series which consists of two products the AQT 420 and AQT 410. The AQT 410 measures of the most common urban air pollutants NO2, SO2, CO and O3  whilst the AQT 420 measures particulate matter (PM2.5 and PM10). The measurement performance of the AQT 400 series is based on proprietary advanced algorithms that enable parts per billion (ppb) measurements by using electrochemical sensors. The algorithms compensate for the impact of ambient conditions and it is specifically designed for urban areas, road networks or around industrial sites and transportation hubs. Because of its small weight and compact size, it is ideally suited for deployment even in larget air quality networks. The measurement data is sent wirelessly to a web-based database with a gateway solution or through a serial interface.The AQT400 series device has a maintenance and calibration interval of 12-24 months depending on local conditions.
The recommended monitoring sites for this study will include 3 continuous air monitoring stations whereby a) it is typically very close to roads with high traffic use b) close to large point sources of industrial activity and c) a typical residential area. The continuous monitoring method is a high-resolution method that provides continuous records of contaminant levels. They can operate over extended periods (weeks or months) with minimal operator intervention and have a high degree of measurement precision. The 3 sites will be carefully selected after consultation with the Lautoka City council to ensure that the monitoring equipment is safe and is not vulnerable to vandalism. Monitoring will be conducted  Also, the site has to be accessible and other factors such as restricted air flows in the vicinity of the sample inlet and changes around the monitoring site will be considered prior to setting up the equipment.
