“…Also were presented comprehensive discussions on the importance of sinks and transformation processes in nanoparticle dispersion models at various spatial scales. Their recent article discussed the technical challenges in tackling regulatory concerns over atmospheric nanoparticles [27] and the follow-up work summarised their impacts on urban air quality and public health [28]. Their most recent work discussed the importance of nanoparticles produced by building activities such as construction, demolition or recycling, besides highlighting the need for developing risk assessment and management strategies [29].…”

Atmospheric nanoparticles are a pollutant currently unregulated through ambient air quality standards. The aim of this chapter is to assess the environmental and health impacts of atmospheric nanoparticles in European environments. This chapter begins with the conventional information on the origin of atmospheric nanoparticles, followed by their physical and chemical characteristics. A brief overview of recently published review articles on this topic is then presented to guide those readers interested in exploring any specific aspect of nanoparticles in greater detail. A further section reports a summary of recently published studies on atmospheric nanoparticles in European cities. This covers a total of about 45 sampling locations in 30 different cities within 15 European countries for quantifying levels of roadside and urban background particle number concentrations (PNCs). Average PNCs at the reviewed roadside and urban background sites were found to be 3.82 AE 3.25 Â 10 4 and 1.63 AE 0.82 Â 10 4 cm À3 , respectively, giving a roadside to background PNC ratio of~2.4. Engineered nanoparticles are one of the key emerging categories of airborne nanoparticles, especially for the indoor environments. Their ambient concentrations may increase in future due to widespread use of nanotechnology integrated products. Evaluation of their sources and probable impacts on air quality and human health are briefly discussed in the following section. Respiratory deposition doses received by the public exposed to roadside PNCs in numerous European locations are then estimated. These were found to be in the 1.17-7.56 Â 10 10 h À1 range over the studied roadside European locations. The following section discusses the potential framework for airborne nanoparticle regulations in Europe and, in addition, the existing control measures to limit nanoparticle emissions at source. The chapter finally concludes with a synthesis of the topic areas covered and highlights important areas for further work.

“…Some of the key factors affecting the IAQ include: (i) concentrations of outdoor air pollutants penetrating to the indoor environments, (ii) building materials such as asbestos, cement, wood preservatives, and volatile organic compounds released from paints, glues, resins, polishing materials, perfumes, spray propellants and cleaning agents, (iii) building characteristics such as the air tightness and ventilation, (iv) building occupancy and living space, (v) equipment used within the buildings (e.g. photocopiers, printers, heaters), (vi) the customs, habits and tradition of the residents, and (vii) the economic status of occupants [14].…”

Study of indoor air quality (IAQ) has received attention of the researchers and policy makers over the last several years due to its affiliation with the adverse health effects and occupants' discomfort. This article focuses on the importance and need of IAQ studies in Indian rural and urban indoor environments. A number of questions in this context are posed and addressed, together with identifying the allied research gaps and missing links in the existing literature. Also discussed are the technical challenges to carry out the IAQ studies in India, and the initiatives and future road map required to overcome them.
