“…Friction tends to knock off the negative electrons and produce an overdose of positive ions. On a dusty or humid day this overdose may be massive because the negative ions (Gabbay, 1990) promptly attach themselves to particles of dust, pollution or moisture and lose their charge. Therefore, as shown in Fig.…”

“…Negative air ionization has been shown to be effective for reducing viral transmission of newcastle diseases virus between 27 and 100% (Estola et al, 1979;Mitchell and King, 1994). This indicates that negative ions inside the poultry are attached to the aerosol particles and larger aerosol particles are produced from the smaller aerosol particles (Gabbay, 1990). Poultry farm is the dustiest site.…”

The air ions are continuously generated and destroyed by various processes in the atmosphere. Near the surface, the nature of ions is very complex and they show large variations in their physical properties. The attachment of small ions to the aerosol particles is depending on the mobility of air ions. High mobility air ions immediately are attached to the aerosol particles and settle down on the surface. In this study we report, about the air ion variation at different sites like Rural, Coastal, Mountain, Poultry farm and urban in the state of Maharashtra in India. The aim of this study is to understand the plausible distribution of air ions both diurnally and at different times in a day for long time (three years) and with various meteorological variables. The preliminary analysis of the data has reveled that negative air ions are observed to have attached to the aerosol particles and large aerosol particles are formed from small aerosol particles. Therefore uni-polarity factor observed to be below unity for coastal, mountain and rural site and about 2.8 at an urban site. However worst case is observed at the Poultry farm, where uni-polarity factor is 6.3, which is very harmful for human health. There is also effect of meteorological parameters on air ion concentration in the atmosphere.

“…Many electric appliances have negative-ion functions [9]. There is a great potential for utilization of NAI generators in preventing decay of fruits and vegetables [10], reducing the ambient air microbial load [11] and hospital-acquired infections in clinics [12,13] as well as preventing the spread of diseases in animal houses [14].…”

This review intends to cover a range of brief description of the generation mechanisms, the determination of the concentration, and the identification of negative air ions (NAI). This is divided into two parts: (i) it pays attention to the generation of NAI, which contains natural and artificial methods. According to the variation of energy in the environment, different methods based on natural generation are introduced in detail. As for artificial generation of NAI, corona discharge is dominantly elaborated due to its preponderance in convenient to control of the concentration of ions. (ii) it tends to introduce the determination of NAI, containing quantitative and qualitative detection, by using ion counting device and mass spectrometer, respectively.
