34th SEGH International Conference on Geochemistry for Sustainable Development

26 November 2017
AVANI Victoria Falls Resort, Livingstone, Zambia 2-7th July 2018. Registrations now open.

We cordially invite SEGH members and new friends to join the SEGH 2018 conference next to Victoria Falls in Livingstone, Zambia. Please view the conference website for details https://segh2018.org/ .

These are exciting times for African development across many sectors, including rapid technological advancement in I.T. and communications, Agriculture, Public Health, Mining and infrastructure development, alongside rapid urbanisation.  The scientific fields represented by SEGH are presented with challenges/opportunities to provide scientific information to the general public, government, industry and donor stakeholders.  The 34th SEGH International Conference is therefore organised around four themes under the banner of ‘Geochemistry for Sustainable Development’:

Theme 1. Industrial and Urban Development

Theme 2. Agriculture

Theme 3. Health

Theme 4. Technologies

More information around these themes can be found on the conference webpage.

You will find additional information about the conference venue, location, how to get to Livingstone, surrounding town and opportunities for experiencing the natural wonder of Victoria Falls.  In addition, we have posted some information on suggestions for local accommodation for a range of budgets to which we will keep you updated as we confirm discounts with local accommodation via: https://segh2018.org/, twitter on @SocEGH, @segh2018, www.segh.net updates and member emails.  On the conference website you will find information for registration and submission of abstracts.  Delegate payments will be handled in two ways.  Zambian nationals and sponsors to pay via the Zambian online shop, international delegates and sponsors to pay via the International online shop which will connect to the SEGH secure payment function using SagePay. Bank transfers can be made on request.

Sponsors and exhibitors are very welcome to support the conference and enrich the meeting by showcasing their capabilities.  This conference presents a unique opportunity to reach a number of delegates from across the world and African region, spanning multi-disciplinary science as shown by the themes, drawn from academia, government agencies, NGOs and industry.

We have formulated a comprehensive social programme including the ice-breaker-registration, two poster evenings, each with drinks, food and music and the conference dinner (Boma) which will be held on the banks of the Zambezi in site of the edge of Victoria Falls. A braai (barbecue) will be provided at the Boma along with entertainment including traditional dancing and music. With support from sponsors, we aim to keep these costs within the registration fee.  See https://segh2018.org/

July 3-5th will comprise of conference presentations, whilst the 6th July will be offered to delegates as a free training day.  Details are shown on the conference website, please feel free to suggest other ideas or volunteer to run small working groups. On the 7th July will be a field trip to visit an African cultural centre, Agricultural research station and finish with a sunset cruise on the Zambezi.  We just ask for a contribution to the lunch on the fieldtrip and payment for the cruise, which includes a buffet and drinks.

Registrations are now open. We look forward to seeing you beside the Victoria Falls known as Mosi-Oa-Tunya, in Livingstone, Zambia.

  • Total arsenic concentrations in Chinese children’s urine by different geographic locations, ages, and genders 2018-06-01

    Abstract

    Little is known about the variation of Chinese children’s exposure to arsenic by geography, age, gender, and other potential factors. The main objective of this study was to investigate the total arsenic concentration in Chinese children’s urine by geographic locations, ages, and genders. In total, 259 24-h urine samples were collected from 210 2- to 12-year-old children in China and analyzed for total arsenic and creatinine concentrations. The results showed that the upper limit (upper limit of the 90% confidence interval for the 97.5 fractile) was 27.51 µg/L or 55.88 µg/g creatinine for Chinese children. The total urinary arsenic levels were significantly different for children in Guangdong, Hubei, and Gansu provinces (P < 0.05), where the upper limits were 24.29, 58.70, and 44.29 µg/g creatinine, respectively. In addition, the total urinary arsenic levels were higher for 2- to 7-year-old children than for 7- to 12-year-old children (P < 0.05; the upper limits were 59.06 and 44.29 µg/g creatinine, respectively) and higher for rural children than for urban children (P < 0.05; the upper limits were 59.06 and 50.44 µg/g creatinine, respectively). The total urinary arsenic levels for boys were not significantly different from those for girls (P > 0.05), although the level for boys (the upper limit was 59.30 µg/g) was slightly higher than that for girls (the upper limit was 58.64 µg/g creatinine). Because the total urinary arsenic concentrations are significantly different for general populations of children in different locations and age groups, the reference level of total urinary arsenic might be dependent on the geographic site and the child’s age.

  • The pollution characteristics of PM 2.5 and correlation analysis with meteorological parameters in Xinxiang during the Shanghai Cooperation Organization Prime Ministers’ Meeting 2018-06-01

    Abstract

    The pollution characteristics of PM2.5 and correlation analysis with meteorological parameters in Xinxiang during the Shanghai Cooperation Organization Prime Ministers’ Meeting were investigated. During the whole meeting, nine PM2.5 samples were collected at a suburban site of Xinxiang, and the average concentration of PM2.5 was 122.28 μg m−3. NO3 , NH4 +, SO4 2− accounted for 56.8% of the total water-soluble ions. In addition, with an exception of Cl, all of water-soluble ions decreased during the meeting. Total concentrations of crustal elements ranged from 6.53 to 185.86 μg m−3, with an average concentration of 52.51 μg m−3, which accounted for 82.5% of total elements. The concentrations of organic carbon and elemental carbon were 7.71 and 1.52 μg m−3, respectively, lower than those before and after the meeting. It is indicated that during the meeting, limiting motor vehicles is to reduce exhaust emissions, delay heating is to reduce the fossil fuel combustion, and other measures are to reduce the concentration of PM2.5. The directly dispersing by mixing layer height increase and the indirectly reducing the formation of secondary aerosol by low relative humidity, and these are the only two key removing mechanisms of PM2.5 in Xinxiang during the meeting.

  • Review of total suspended particles (TSP) and PM 2.5 concentration variations in Asia during the years of 1998–2015 2018-06-01

    Abstract

    In Asian countries such as China, Malaysia, Pakistan, India, Taiwan, Korea, Japan and Hong Kong, ambient air total suspended particulates and PM2.5 concentration data were collected and discussed during the years of 1998–2015 in this study. The aim of the present study was to (1) investigate and collect ambient air total suspended particulates (TSP) and PM2.5 concentrations for Asian countries during the past two decades. (2) Discuss, analyze and compare those particulates (TSP and PM2.5) annual concentration distribution trends among those Asian countries during the past two decades. (3) Test the mean concentration differences in TSP and PM2.5 among the Asian countries during the past decades. The results indicated that the mean TSP concentration order was shown as China > Malaysia > Pakistan > India > Taiwan > Korea > Japan. In addition, the mean PM2.5 concentration order was shown as Vietnam > India > China > Hong Kong > Mongolia > Korea > Taiwan > Japan and the average percentages of PM2.5 concentrations for Taiwan, China, Japan, Korea, Hong Kong, Mongolia and Other (India and Vietnam) were 8, 21, 6, 8, 14, 13 and 30%, respectively, during the past two decades. Moreover, t test results revealed that there were significant mean TSP and PM2.5 concentration differences for either China or India to any of the countries such as Taiwan, Korea and Japan in Asia during the past two decades for this study. Noteworthy, China and India are both occupied more than 60% of the TSP and PM2.5 particulates concentrations out of all the Asia countries. As for Taiwan, the average PM2.5 concentration displayed increasing trend in the years of 1998–1999. However, it showed decreasing trend in the years of 2000–2010. As for Korea, the average PM2.5 concentrations showed decreasing trend during the years of 2001–2013. Finally, the average PM2.5 concentrations for Mongolia displayed increasing trend in the years of 2004–2013.
