EANET Research Fellowship Programme – The impacts of exposure to fine particulate matter on premature mortality in Bangkok, Thailand

Posted on by Aurélia Lemoine

EANET Fellowship 2018 featured image

1 December 2020 – Niigata, Japan

The Acid Deposition Monitoring Network in East Asia (EANET)’s fellowship program aims at funding researchers from the EANET’s participating countries to carry out research pertaining to acid deposition at the Network Center in Japan. Kessinee Unapumnuk, from Thailand, was awarded the EANET fellowship for 2018. She led her research on the impacts of exposure to fine particulate matter on premature mortality in Bangkok.

.

The impacts of fine particulate matters on human health

Fine particulate matters (PM2.5) affect human health and can lead to premature death if exposed for a long time. Chronic exposure to PM2.5 increases the risk of developing cardiovascular and respiratory diseases, as well as lung cancer. The World Health Organization (WHO) reported 4.2 million premature deaths due to cardiovascular and respiratory diseases and cancers worldwide in 2016 related to the exposure to ambient PM2.5 in both urban and rural areas.

Bangkok, Thailand’s capital, has been experiencing frequent episodes of air pollution characterized by a high concentration of PM2.5 due to combustion emissions from multiple sources and stagnant metrological conditions from January to April every year. Transportation-related sources are the major contributions to the PM2.5 levels and result in poor air quality in the city.

.

Understanding premature mortality attributable to PM2.5 in Bangkok’s districts

Unapumnuk has estimated premature mortalities caused by chronic obstructive pulmonary disease (COPD), lung cancer (LC), ischemic heart disease (IHD), and stroke attributed to long-term exposure to PM2.5 in several districts in Bangkok from 2010 to 2017.

In conclusion, the study suggests that a strict emission control of PM2.5 is needed in Bangkok to avoid significant mortality attributable to PM2.5.

.

Under the EANET Research Fellowship program 2018, this study was conducted at the Asia Center for Air Pollution (ACAP), Niigata Japan. The author acknowledged the help received from the Asia Centre for Air Pollution Research (ACAP) for performing the research as well from the Thai Pollution Control Department and the Ministry of Public Health.

EANET Research Fellowship Programme – Study on the impacts of air pollution transport and its effects to human health in Cambodia

Posted on by Aurélia Lemoine

17 February 2021 – Niigata, Japan

The Acid Deposition Monitoring Network in East Asia (EANET)’s fellowship programme aims at funding researchers from the EANET’s Participating Countries to carry out research pertaining to acid deposition at the Network Center in Japan. Kong Savuth, from Cambodia, was awarded the EANET fellowship in 2018. Mr. Savuth’s research described human health effects of exposure to air pollutants, namely, ozone (O3) and particulate matter (PM2.5) in reference to the WHO Air quality guidelines (2005).

.

Impacts of air pollutants on human health

PM2.5 can penetrate deep inside the lungs and contribute to increasing the risk of cardiovascular and respiratory diseases including lung cancer. According to recent epidemiological studies, reducing the annual average PM2.5 concentrations of 10 μg m-3 could result in a significant reduction of premature mortality.

Ground-level O3 can cause respiratory problems leading to asthma, cough, inflammation of the respiratory tract, chronic bronchitis, and lung damage. A high-level concentration of O3 also causes premature mortality.

WHO estimates that in 2016, some 58% of outdoor air pollution-related premature deaths were due to ischaemic heart disease and strokes, while 18% of deaths were due to chronic obstructive pulmonary disease and acute lower respiratory infections respectively, and 6% of deaths were due to lung cancer.

 

.

Estimating premature mortality caused by PM2.5 and O3 in Cambodia

The researchers (Savuth and Yamashita) estimated premature mortality caused by the exposure to PM2.5 and O3 in Cambodia by using PM2.5 and O3 data simulated by CMAQ (Community Multiscale Air Quality – a chemical transport model) and Concentration-Response (C-R) functions.

 

Read the full study and its results, published in the EANET Science Bulletin, Vol 5.

Under the EANET Research Fellowship programme 2018, this study was conducted at the Asia Center for Air Pollution (ACAP), Niigata, Japan. The researcher, Kong Savuth, acknowledged the support and facilities provide by ACAP and by the National Institute for Environmental Studies (NIES), Japan, for performing the research.

Komarovka river by Hiroyuki SASE

17 September – Niigata, Japan

The Acid Deposition Monitoring Network in East Asia (EANET)’s fellowship program aims at funding researchers from the EANET’s participating countries to carry out research pertaining to acid deposition at the Network Center in Japan. Ekaterina Zhigacheva, from Russia, was awarded the EANET fellowship in 2017. She led her research on the investigation of atmospheric input and runoff discharge of sulphur and nitrogen compounds as the balance components of Komarovka river catchment by long-term observations at the Russian EANET Primorskaya station (for 2005 – 2015).

.

The impact of acid deposition on rivers

Air pollution consists of significant amounts of compounds of sulphur and nitrogen. These compounds deposit on the earth’s surface through wet and dry depositions and cause detrimental impacts on the ecosystems and environment, including acidification of the water bodies, such as rivers and lakes.

Zhigacheva, in this study, analysed the components of the Komarovka river catchment at Russian EANET Primorskaya station using observations from 2005 to 2015. The goal of the study was to evaluate the effects of pollution on regional ecosystems.

 

The author acknowledged the help received from the EANET Primorskaya site and PCEM laboratory for data and financial support and facilities from the Asia Centre for Air Pollution Research (ACAP) for performing the research.
