Health Hazard

Health of every living being is dependent on level pollutant in the environment, weather condition, etc, which are interrelated and influencing each other. Presence pollution particles high percentage such as particulate matter size 10 2.5 (PM10, PM25) microns creates higher risk lung functionality, respiratory disease reduces cardio functionality; also affects quality water sources. Rainfall, technically known precipitation, occur at non season create health hazards, seasonal diseases. In our previous work, relationship between precipitation were analysed; it observed that attribute matter, PM2.5, influences precipitation. Pollution data well numerical time series nature. This research work analyses (day wise observations) weather, recorded Chennai city year 2017. ARIMA model constructed after applying required transformations underlying data. Trend seasonality found set unique since components data-dependent autocorrelated with day observations. Improved forecasting PM2.5 obtained through modelling.
