Remedial Solutions for polluted soils: developing research collaboration between UK and China

Hunan University of Science & Technology (HNUST), Xiangtan, PR, China. The School of Civil Engineering houses a Key Library for Shale Gas extraction and has undertaken work to assess resources and their low impact extraction.
 
SEGH member and former President Professor Andrew Hursthouse, of the University of the West of Scotland, has been working in the Hunan University of Science & Technology (HNUST), Xiangtan, PR, China. Andrew spent a month during September and October 2015, based in the School of Civil Engineering, developing a research programme based on soil and groundwater treatment approaches to agricultural and resource development problems. The School houses a Key Library for Shale Gas extraction and has undertaken work to assess resources and their low impact extraction. These are important issues, particularly in the Hunan region of China. Wide spread non-ferrous metal extraction in the region has also created problems for food safety and research into locally viable management strategies is needed.
 
 
The project has been supported by the award of research fellowships to Prof Hursthouse through the Overseas Chair Professor “Xiangjiang Scholars Programme” 2013-14 and High End Expert Recruitment – fellowship in contaminated land research 2014-15, from the State Administration of Foreign Experts affairs, Peoples Republic of China. The visits have involved seminars and knowledge exchange and research programme fieldwork with colleagues from HNUST and the University of Hunan in Changsha. Interests in the re-use of waste materials for low cost treatment of contaminated soils are being developed using experiences from applications in the EU.

  • Status, source identification, and health risks of potentially toxic element concentrations in road dust in a medium-sized city in a developing country 2017-09-19

    Abstract

    This study aims to determine the status of potentially toxic element concentrations of road dust in a medium-sized city (Rawang, Malaysia). This study adopts source identification via enrichment factor, Pearson correlation analysis, and Fourier spectral analysis to identify sources of potentially toxic element concentrations in road dust in Rawang City, Malaysia. Health risk assessment was conducted to determine potential health risks (carcinogenic and non-carcinogenic risks) among adults and children via multiple pathways (i.e., ingestion, dermal contact, and inhalation). Mean of potentially toxic element concentrations were found in the order of Pb > Zn > Cr(IV) > Cu > Ni > Cd > As > Co. Source identification revealed that Cu, Cd, Pb, Zn, Ni, and Cr(IV) are associated with anthropogenic sources in industrial and highly populated areas in northern and southern Rawang, cement factories in southern Rawang, as well as the rapid development and population growth in northwestern Rawang, which have resulted in high traffic congestion. Cobalt, Fe, and As are related to geological background and lithologies in Rawang. Pathway orders for both carcinogenic and non-carcinogenic risks are ingestion, dermal contact, and inhalation, involving adults and children. Non-carcinogenic health risks in adults were attributed to Cr(IV), Pb, and Cd, whereas Cu, Cd, Cr(IV), Pb, and Zn were found to have non-carcinogenic health risks for children. Cd, Cr(IV), Pb, and As may induce carcinogenic risks in adults and children, and the total lifetime cancer risk values exceeded incremental lifetime.

  • In vivo uptake of iodine from a Fucus serratus Linnaeus seaweed bath: does volatile iodine contribute? 2017-09-02

    Abstract

    Seaweed baths containing Fucus serratus Linnaeus are a rich source of iodine which has the potential to increase the urinary iodide concentration (UIC) of the bather. In this study, the range of total iodine concentration in seawater (22–105 µg L−1) and seaweed baths (808–13,734 µg L−1) was measured over 1 year. The seasonal trend shows minimum levels in summer (May–July) and maximum in winter (November–January). The bathwater pH was found to be acidic, average pH 5.9 ± 0.3. An in vivo study with 30 volunteers was undertaken to measure the UIC of 15 bathers immersed in the bath and 15 non-bathers sitting adjacent to the bath. Their UIC was analysed pre- and post-seaweed bath and corrected for creatinine concentration. The corrected UIC of the population shows an increase following the seaweed bath from a pre-treatment median of 76 µg L−1 to a post-treatment median of 95 µg L−1. The pre-treatment UIC for both groups did not indicate significant difference (p = 0.479); however, the post-treatment UIC for both did (p = 0.015) where the median bather test UIC was 86 µg L−1 and the non-bather UIC test was 105 µg L−1. Results indicate the bath has the potential to increase the UIC by a significant amount and that inhalation of volatile iodine is a more significant contributor to UIC than previously documented.
