Acid Rain in Singapore due to Nuclear Leakage in Fukumi, Japan

Acid Rain due to Nuclear Leakage in Fukumi, Japan?

Native species in Singapore may be wiped out by acid rain

    “A nuclear power plant in Fukumi, Japan exploded at 430am. If it rains tomorrow or later, don’t go outside. If you are outside, be sure that you have rain protectors. It’s acid rain. Don’t let it touch you. You may burn you skin, lose your hair or have cancer. Please paa, stay safe and remind everyone you know “

Have you received this kind of sms/email/massage about acid rain due to nuclear leakage in Japan?? I did received sms and emails. Don’t be overreact or over speculate the situation. Read reliable news like ChannelNewsAsia before come to the conclusion. This is also applicable to Malaysia as our location is next to Singapore.

Overrated or over speculation may cause people to panic, people tend to distresses. Sharing is good thing, but sharing uncertain news may cause things goes wrong.

Note : at 1st, I am the one who overreacted when received this sms/email and asked Mr Hubby to bring along his umbrella everyday to office. But it’s doesn’t make sense to him to do so, and he ask me to read this.. Yea, Yayang, Malaysia jauh from Japan, hujan acid tue singgah Korea or China jer.

More recently, alarm has been expressed about increasing levels of acidification in East Asia.2-4 Approximately one-third of the world's population resides in East Asia and the region has been experiencing phenomenal economic growth over the past two decades. The rapid growth of industrial and agricultural production, especially in China, India, Thailand, and Indonesia, has resulted in a remarkable increase in SO2 and NOx emissions during the past decade, and these emissions look set to grow further. Although emissions of these pollutants are lower than in Europe and the US on a per capita basis, experts predict that total emissions in East Asia will surpass the combined emissions of Europe and the US by the year 2020.

The main reasons for the increasing pollution are the low quality of fuel in most of East Asia (the S content can be as high as 7 per cent in Thai lignite and up to 5 per cent in Chinese brown coal) and the absence of control technologies in many countries. There is concern that these increasing emissions will cause enormous environmental damage, with some impacts already apparent. Governments throughout the region are starting to treat the problem with growing urgency, and in China abatement of acid rain is now considered a top government priority.

Studies of rainwater composition were first reported in Japan in 1894, and today Japan has the most advanced acid rain monitoring and abatement programme in the region. The Japan Environment Agency (JEA) has been monitoring acid rain since the early 1970s. In 1983 this agency established the National Acid Deposition Monitoring Network, which samples rainwater at 48 sites throughout the country, together with routine analysis of surface waters and soils. In China, the Institute of Environmental Chemistry initiated a rainwater survey in the late 1970s, and nationwide surveys have been carried out since 1982. Measurements in 82 Chinese cities from 1991 to 1995 showed the occurrence of acid rain, with average annual pHs <5.6, in nearly half of the cities. Southern cities were the worst affected: 87 per cent of cities south of Qingling Mountain and Huaihe River were affected by acid rain and the lowest pH value was 3.52 in Changsha, Hunan province.

The chemical composition of rainwater in China is different from that in Europe; rainwater in China has lower pH values and higher sulfate, calcium and ammonium concentrations. Furthermore, the concentration of calcium relative to sulfate is very high in China while nitrate concentrations are low relative to other components. Rainwater has been routinely monitored at 14 sites throughout Malaysia since 1985 as part of the National Acid Rain Monitoring Network, and a rainwater monitoring station was set up in Brunei in 1995 by the Brunei Meteorological Service. South Korea, Taiwan and Hong Kong also have well developed rainwater monitoring networks. In Taiwan, approximately 70 per cent of rainfall is considered to be acidic, with pH values <5.6.
