Acid rain is caused by emissions of sulphur dioxide dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Using first-principles simulations, we show that HOSO displays an unforeseen strong acidity (pKa = −1) comparable with that of nitric acid and is fully dissociated at the air–water interface.

It is hoped that China will learn the lesson from the UK, and decouple its economic growth from the detrimental impact of environment. The aim of this work is to highlight the importance of air quality indexes (AQIs) in air quality assessment.Three different long-term AQIs - Long-term Air Quality Index (LAQx), Aggregated Air Quality Index (AAQI), Oak Ridge Air Quality Index (ORAQI) - were calculated and compared, using data between 2007 and 2016.

More than 50 years, scientists, government officials, environmentalists, and industry representatives have investigated the causes and consequences of acid rains and proposed many solutions.

Three year mean of wet sulphate deposition in USA in different periods (Source: US EPA, 2013). The sulphuric acid and nitric acid are the main causes of acid rain. TERMINOLOGY Public awareness of air pollution dangers has raised noticeably the need for a concept like air quality index (AQI) as a timely information about the potential changes in air quality.
