Abstract

Purpose

Air quality and its assessment in urban areas has become a necessity. This is attributed to the increasing air pollution in urban landscape from anthropogenic activities necessary for economic growth and development. This study investigates air quality and potential health risk posed from nitrogen dioxide (NO2) to the residents of low town of Mohammedia city, Morocco.

Design/methodology/approach

The NO2 concentration was measured on an hourly basis for the winter season of the year 2014, 2015 and 2016. The air quality was assessed in terms of Air Quality Index (AQI). Noncarcinogenic risk assessment was done to evaluate possible health risk to the inhabitant of low town from NO2 exposure.

Findings

The maximum concentration reached 85–96 µg/m3 (at 6 p.m., 2014), 96–104 µg/m3 (7–9 p.m., 2015) and 102–117 (8–11 p.m., 2016). The AQI during maximum NO2 levels (peak hours) ranged between 0–50 µg/m3 (good) to 51–100 µg/m3 (unhealthy for sensitive group). The risk quotient (RQ) was calculated for average daily intake and average hourly intake of NO2. RQ was found to be less than 1 (no potential health risk, lifetime and hourly) for all three years. However, increase in RQ value from 0.84 (2014) to 0.98 (2016) indicates increase in potential health risk. Hence, policy and measures should be adopted to reduce the potential health risk.

Originality/value

This study is very first of its kind for the area and hence can serve as reference study for future works. Further studies are required to assess air pollution in other seasons (summer, spring, autumn), impact of climatic condition and parameters on air quality. Also, for direct impact assessment number of cases attributed to air pollution needs to be investigated.
