Prashant Kumar from the University of Surrey Faculty of Engineering and Physical Sciences led a team of researchers in a study that highlighted the importance of unregulated and unaccounted primary pollution sources those that emit pollution directly into the air in and around Delhi.

In addition, the research discussed the challenges associated with developing effective air pollution control strategies. This year Delhi has been ranked fifth out of the 32 megacities in the world in terms of population approximately 26 million.

Being land locked, there are few opportunities to flush polluted air out or to replace it with cleaner air from maritime regions, and this puts Delhi at a distinct disadvantage.

In addition to unregulated and accounted pollution sources within Delhi, there are a number of other factors that contribute to air pollution in the city.

Delhi shares this characteristic with growing megacities such as Tehran and Cairo in which urban growth is increasingly heterogeneous and sometimes unplanned. In contrast, megacities close to the coast benefit from sea breezes that exchange maritime and urban air once each day. In developing countries, such knowledge is reasonable, however there is a general lack of high quality spatially disaggregated primary emissions inventories for many megacities including Delhi.

As a result, emissions factors become inadequate or outdated and unaccounted and unregulated sources are often left out of inventories. Emission inventory and source apportionment studies typically include emissions from on road vehicles, power plants and the resuspension of particulates, however city specific sources are sometimes left out.

Important sources for Delhi include brick kilns fuelled by raw wood, agricultural waste or poor quality coal, the roadside burning of organic and plastic waste, the unintentional burning of municipal solid waste at landfills and construction activities.

Traffic congestion is a ubiquitous air pollution source in cities, and in Delhi it is emphasised by the very high density activities and limited infrastructure in the city.

Introduction

Cooking by the burning of solid biomass or cow dung is another important but poorly quantified air pollution source that emits gaseous and particulate pollutants.

Diesel generators for temporary power generation have been considered in some emissions inventories in India such as the Six Cities Program of the Central Pollution Control Board in India.

In areas of poor power network resilience or undersupply, diesel generators are particularly important. They tend to be fuelled by poorer quality diesel with a high sulphur content and may not be regularly serviced. Their emissions including nitrogen oxides, carbon monoxide, hydrocarbons, particulates and smoke may also not be checked by regulators.

Emissions at traffic intersections are made worse by poor exhaust control measures and the heterogeneous nature of the fleet. Unregulated small industries use a variety of energy sources eg.
