Society for Environmental Geochemistry and Health

SEGH was established in 1971 to provide a forum for scientists from various disciplines to work together in understanding the interaction between the geochemical environment and the health of plants, animals, and humans. We recognise the importance of interdisciplinary research. SEGH members represent expertise in a diverse range of scientific fields, such as biology, engineering, geology, hydrology, epidemiology, chemistry, medicine, nutrition, and toxicology.

  • Temperature inversion and air pollution relationship, and its effects on human health in Hanoi City, Vietnam 2018-09-18

    Abstract

    This study aimed to investigate the effects of temperature inversions on the concentration of some pollutants in the atmosphere in Hanoi City, Vietnam, during the period from 2011 to 2015. This work also aimed to evaluate relationships between the thermal inversion and health effects that are associated with air pollution. During this period, the temperature inversions were most frequently presenting from November to March in Hanoi City. Air quality data was gathered from air quality monitoring stations located in the study area. The data showed that levels of NO2, SO2, PM10 and PM2.5 increased when the inversions strengthened. Cases of two types of diseases (acute respiratory diseases and cardiovascular diseases), which are linked to atmospheric air pollution, were considered on number of patients under 15 and above 60 years old at National Geriatric Hospital and National Otorhinolaryngology Hospital. There was significant increase in the daily average number of hospital visits with increasing surface-based inversions. The statistical analysis showed that the temperature inversions correlated with concentration of air pollutants and the number of patients in 5 years.

  • Evaluation of the diagnostic ratios of adamantanes for identifying seriously weathered spilled oils from simulated experiment and actual oil spills 2018-09-17

    Abstract

    The composition and physical properties of spilled oil have great changes during the seriously weathering process. It brings great difficulties to the source identification of oil spill. So the stable and trustworthy diagnostic ratios (DRs) for accurate identification of severely weathered spilled oils are very important. The explosion of Sinopec pipeline happened on November 22, 2013 at Qingdao, China. Local beaches at Jiaozhou Bay were polluted by spilled oils. We have collected original spilled oil samples from an area free from human interference near the oil leakage point after the accident. Synchronized with actual beach weathering, laboratory experiments were conducted to simulate oil weathering for 360 days by using the collected original spilled oil samples. Based on t test and the repeatability limit method, 50 diagnostic ratios (DRs) of adamantanes were screened. Four DRs, namely 1,3-dimethyladamantane/total dimethyladamantane, 1-methyladamantane/(1-methyladamantane + 1,3-dimethyladamantane), dialkyl diamantane/total diamantane, and diamantane/(diamantane + dialkyl diamantane), have maintained remarkable stability during the simulated weathering experiments and field weathering process. These stable ratios can retain the characteristics of oil source during weathering. They are very beneficial to improve the accuracy of identifying the source of severely weathered oil and can be used as an effective supplement to existing index system for source identification.

  • Environmental impact assessment of uranium exploration and development on indigenous land in Labrador (Canada): a community-driven initiative 2018-09-17

    Abstract

    There is hardly any study on environmental impacts of uranium exploration and mining development prior to actual mining activities. Rather, the majority of the literature addresses the environmental impacts of either ongoing or decommissioned mines. The objective of the study was to measure the possible radioactive contamination (total uranium and lead) in the local ecosystem surrounding an abandoned uranium development site on indigenous land in Labrador (Canada). Water (brook and ponds), soil/sediments (brook and ponds), plants (growing along the brook and pond shores), and local fish (trout) and clams from bays were collected from mine development site, downstream, and control sites. Uranium and lead mobilization in the local environment appears to be slightly enhanced near the proposed mining site, but rapidly drops downstream. Developing a low-cost, community-based environmental health monitoring tool is an ideal strategy for generating baseline information and further follow-up.
