Taoyuan suffers most acidic rain in Taiwan: three-year academic study

TAIPEI, Taiwan -- Acid rain occurs on 60 percent of rainy days in Zhongli City in Taoyuan County, the highest percentage in Taiwan, according to a three-year academic study commissioned by the Environment Protection Agency.

The acidity level in Taoyuan county is equivalent to tomato juice and the county is followed by Hsinchu county, Yangmingshan National Park, Yilan County, and downtown Taipei, in terms of acid precipitation. In Taipei, acid rain is recorded on 39 percent of rainy days.

Taoyuan is the home to over 10,000 factories and has 1.75 million motor vehicles. It has the third highest pollution rate in Taiwan,

Acid rain possesses elevated levels of hydrogen ions, which can harm plants, aquatic animals and infrastructure. It is caused by sulfur dioxide and nitrogen oxide, which react with water molecules in the atmosphere to produce acids. The two chemicals are mainly produced by the burning of fossil fuel.

Serious exposure to acid rain poses several health hazards, including asthma.

According to the EPA, acid rain in northern Taiwan is partially caused by pollutants generated outside the island which then arrive in Taiwan. The EPA suggested this phenomenon is evidenced by higher levels of acidity during the northeast monsoon season, which runs from October and April every year.

Taiwan has kicked off cooperation with mainland China, Japan and the U.S. to develop a solution to acid rain in east Asia, said the agency.

All rain is slightly acidic. Caused by carbonic acid, formed from the hydrolysis of carbon dioxide (which is primarily the result of humans exhaling).
Hold your breath. Be happy that you are not contributing to the problem.
