Spatial Variation of Ground Level Ozone Concentrations and its Health Impacts in an Urban Area in India.

ABSTRACT: The present study was designed to analyze the spatial distributions of ground-level ozone (GLO) concentrations in Ranchi (Jharkhand, India) using geostatistical approaches. From September 2014 to August 2015, monthly GLO concentrations were monitored in 40-identified locations distributed in the region of study. In every month, the monitoring was done at three different time periods of the day; 5.30 AM to 7.30 AM, 11.30 AM to 1.30 PM, and 5.30 PM to 8 PM). The time duration was assigned based on the temporal variations of GLO concentrations. The descriptive statistics indicate that the spatial mean ozone concentrations ranged from 23.45 μg m-3 to 53.91 μg m-3 in morning hours, from 82.50 μg m-3 to 126.66 μg m-3 in the day time and from 40.04 μg m-3 to 71.25 μg m-3 in the evening hours.
