Air ion variation during morning period (06:00-08:00 hours) at rural station Ramanandnagar (17° 4′ N 74° 25′ E) India S.D. Pawar ABSTRACT The atmospheric-electric processes can be understood only if it is assumed that the atmosphere is electrically conducting. The presence of aerosol in the air was found to be very greatly affecting the conductivity. Since the aerosol particles are very large compared to the ions, an ion is more likely to strike against aerosol-particle, and give up its charge to it or to adhere to the surface, than to collide with an ion of opposite sign. In this way, the rate of loss of conductivity is rapid. To measure small currents (AD549JH) amplifier is used by converting it into a voltage, which is usually linearly related to the input current. In January average positive air ions were 9×102 ions per cm3, starts decreasing and reaches to minimum (1.2 × 102 ions per cm3) in April. From May starts increasing and reaches to 9.1 × 102 ions per cm3 in June. Average negative air ions were 6×102 ions per cm3 in January. In February average negative air ions were 5.85 × 102 ions per cm3. From February starts decreasing and reaches minimum (1.2 × 102 ions per cm3) in April. In June average negative air ions were 9.4 × 102 ions per cm3. Average negative air ions were 3 × 102 ions per cm3 in July. From July average negative air ions starts increasing and reaches maximum (8.2 × 102 ions per cm3) in September. The air quality is depends on number of negative air ions present in the atmosphere. In January as compared negative air ions positive air ions were more in the atmosphere. Therefore atmosphere in January month is very harmful to human health during morning period.
