Every year, Hanoi suffers from several episodes (periods with daily concentration of PM2.5 higher than 50 µg m⁻³ during at least two consecutive days). These episodes are of health concern because of the high concentration of PM2.5 and/or PM0.1 and the presence of PM-bound toxic components, such as, PAHs. In this study, the concentrations of PAHs b...
High levels of fine (PM2.5) and ultrafine (PM0.1) particles in the atmosphere can cause adverse effects on the environment and human health. This study aims at determining the mass concentrations of PM and health risks on pollution event days (episodes) in Hanoi. Semi-daily samples (daytime and night-time) of PM2.5 and PM0.1 were collected at Hanoi...
Ngành chăn nuôi lợn có tiềm năng lớn trong việc phát thải sinh khí sinh học và đóng góp quan trọng vào việc phát thải khí nhà kính trong ngành nông nghiệp tại Việt Nam. Nghiên cứu này đã được thực hiện để xác định tổng lượng CH4 và CO2 (eq) được phát thải từ các hoạt động quản lý lợn và hệ số phát thải của CH4 và CO2 (eq) tại các trang trại lợn khá...
. High levels of fine (PM2.5) and ultrafine (PM0.1) particles in the atmosphere can cause adverse effects on the environment and human health. This study aims at determining the mass concentrations of PM and meteorological influencing factors in high pollution event days in Hanoi. Daily samples of PM2.5 and PM0.1 were collected at a mixed site in H...
Haze is a well-known air pollution phenomenon linked to the severe and persistent particulate matter (PM) episodes in Southeast Asia (SEA), which significantly impacts the environment, health, and economy. This work reviewed for the first time the characteristics of haze episodes in terms of PM concentrations, chemical compositions, and the causes...
This study attempted to provide comprehensive insights into the chemical composition, source identification, and health risk assessment of indoor particulate matter (PM) in urban areas of Vietnam. Three hundred and twenty daily samples of PM0.1 and PM2.5 were collected at three different types of dwellings in Hanoi in two seasons, namely summer and...
The study aims to determine the concentration, size distribution and analyze the relationship of indoor and outdoor particles in urban area, in Vietnam. One thousand two hundred daily samples of PM 0.1 , PM 0.1-0.5 , PM 0.5-1 , PM 1-2.5 , PM 2.5-10 , PM >10 were taken simultaneously at four residential houses in summer and winter by nano sampler (M...
Các nghiên cứu dịch tễ học chứng minh rằng, người tham gia giao thông phơi nhiễm với bụi mịn có thể gây những ảnh hưởng xấu tới sức khỏe và gây ra bệnh tật. Các nghiên cứu về phơi nhiễm cá nhân đối với những người tham gia giao thông chưa được thực hiện một cách đầy đủ và tương đối hạn chế ở Việt Nam. Nghiên cứu này nhằm mục đích đánh giá phơi nhiễ...
This paper presents data on the size characterization concentration of PM0.1, PM0.5, PM1, PM2.5, PM10, TSP in indoor and outdoor air of a residential apartment in two seasons (winter and summer) in Hanoi, Vietnam. These particles with different sizes were taken by 5 stage impactors (Nano sampler 3182, KINOMAX). Daily average concentrations of coars...
There is an increasing research interest in indoor air quality at schools as children who are among the most sensitive to air pollution spend a lot of time indoors. This study aims to estimate BTEX levels, sources, and assess their health risk at ten preschools in Hanoi, Vietnam. Two sampling campaigns were conducted in November and December, 2017,...
Hệ thống đỗ xe nhiều tầng có khả năng phát sinh các chất có nồng độ cao BTEX ( Benzene (B), Toluene (T), Ethyl benzene (E) và Xylene (X)), là những chất gây ảnh hưởng xấu đến sức khỏe con người. Mục đích của nghiên cứu này là xác định nồng độ BTEX, nguồn phát sinh và đánh giá rủi ro sức khỏe đối những người bảo vệ làm việc tại các bãi đỗ xe hầm tại...
The World Health Organization (WHO) has estimated that approximately 4 million premature deaths in 2016 were attributable to household air pollution in low to middle income countries. Vietnam is experiencing serious particulate matter (PM) pollution in ambient air and indoor environments, resulting in significant adverse health impacts. This articl...
Indoor air quality is considered to be of great concern due to its adverse impact on the human health nowadays. BTEX concentrations in 29 residential homes including (new/renovated and old) were studied in Hanoi Metropolis and influencing parameters such as smoke habit, cooking appliances, solvent consumption, and ventilation system were considered...
This study investigates PAHs content in road dust of Hanoi metropolis, Vietnam. The samples were colected from the roads around city and analyzed by gas chromatography mass spectrometry (GC/MS). The total PAHs mass concentration ranges from 33.88 μg/kg to 5588,16 μg/kg, with the mean of 356,24 μg/kg in which HMW accounted up 70 % and LMW made up 30...
