11 February 2024 | Story Leonie Bolleurs | Photo SUPPLIED

Beyond the destruction caused by the Coronavirus during the COVID-19 pandemic, it continues to impact not only the lives of many people but also the environment.

Dr Gladys Belle, a postdoctoral researcher in the Centre for Environmental Management at the University of the Free State (UFS), is currently focusing her research on the risk assessment of pharmaceuticals of emerging concern in water resources, specifically concerning human health and aquatic ecosystems. She explains that her research investigates the occurrence, fate, and behaviour of four drugs used during COVID-19 and assesses the risk these drugs pose to human health and the aquatic ecosystem within the Orange-Senqu River Basin.

“I am passionate about water research and more passionate about human health. My interest in water and health-related research grew due to the health crisis caused by human exposure to contaminated water sources in South Africa,” she states.

Dr Belle adds that she wants to raise awareness and shape the behaviour of local communities in South Africa regarding safe disposal methods. Through programmes such as take-back initiatives, the research seeks to reduce the impact of pharmaceuticals on water resources. She states, “My research will also influence the implementation of various preventive measures, including policies regulating the disposal of drugs into the environment. This research may serve as the basis for better sanitation solutions within communities and improving wastewater treatment processes in the country.”

Focusing on women scientists such as Dr Belle, the UFS will be celebrating the United Nations International Day of Women and Girls in Science on 11 February, commemorating women in the field of science and encouraging girls to pursue careers in this field.

A passion for academia and science

From a young age, Dr Belle was deeply enthusiastic about academia, particularly in the field of science. She studied Environmental Sciences at a university in Cameroon, earning her BSc in 2003. Taking a ten-year break, she focused on being a mum and also worked as Biology teacher in Lesotho.

Despite staying away from the university for an extended period, Dr Belle never let go of her passion and vision to one day become a renowned researcher and academic. In 2012, she enrolled for her honours degree in Environmental Health, followed by her master's in 2013, which she passed with distinction. Immediately after, she enrolled for a PhD and successfully graduated in 2021.

She mentions that her PhD journey came with various challenges, balancing responsibilities as a part-time lecturer, a mother, and a wife while pursuing her studies. “Regardless of all those challenges, I never gave up. Instead, they kept me motivated to get going,” she says.

The same year that she obtained her PhD, Dr Belle joined the university as a postdoctoral researcher. “Being a researcher at the UFS has allowed me to advance my research career and provided a platform for me to meet and learn from the gurus in my field,” she comments. Dr Belle considers Prof Paul Oberholster, the Dean of the Faculty of Natural and Agricultural Sciences and her current supervisor, as a true mentor. He not only teaches her the skill of hard work, but he also encourages her to aim high in research. She also expresses great appreciation to the Directorate of Research Development for its support during her research journey, providing her with access to tools and resources to effectively pursue her work as researcher.

As postdoctoral researcher, Dr Belle expanded her research expertise by publishing in peer-reviewed journals and gaining experience in writing grants and managing projects. In 2023, she received two prestigious research grants. In the Water Research Commission grant, she is leading a team of six national and international experts in risk assessment of emerging contaminants in water resources.

Furthermore, Dr Belle received the Innovation Postdoctoral Fellowship award for 2023 from the National Research Foundation (NRF). She explains that the project focuses on investigating sources, pathways, occurrences, and potential risks of pharmaceuticals of emerging concern on potential receptors in water resources. “This study targets the different wastewater treatment plants (WWTP) in Mangaung, as these plants pose a potential risk of introducing pharmaceuticals into water systems,” she remarks.

Strengthening capacity development

Focusing on understanding the risks of new pollutants in water resources, Dr Belle is well on her way to becoming one of the leading researchers in water and health, a long-standing aspiration of hers. “I see myself working with top researchers in my field, both nationally and internationally, to be part of important international research projects, including working with the European Union and the United Nations,” she says.

In addition to making an impact on the international stage and collaborating with experts in her field, she also aims to transfer and share her skills to the postgraduate students working with her, thereby strengthening their development.

For girls and young women aspiring to embark on a journey in any field of science, her message is that it is possible. “Whatever career path you wish to pursue in sciences, put your mind to it and be passionate about what you do; ultimately, you will testify that ‘it is possible’,” Dr Belle concludes.

UFS to investigate implementation of quality-monitoring system for SA food industry

The University of the Free State (UFS) will be investigating the implementation of a quality-monitoring service for the South African food industry.

This was decided during a workshop to discuss the external quality monitoring in the edible oil industry of South Africa, which was recently held at the UFS.

Major role players in the fast-food sector like Nando's, Spur, Captain
Dorego's, King Pie Holdings, Black Steer Holdings, etc and various oil
distributors like Felda Bridge Africa, Refill Oils, PSS Oils and Ilanga Oils attended
the workshop. Also present was Mrs Ina Wilken, Chairperson of the South African National Consumer Union (SANCU) and key-note speaker of this workshop. She represented the consumer.

These role players all pledged their support to the implementation of this quality- monitoring system for the whole food industry.

The decision to implement this system follows the various malpractices reported in the press and on TV concerning food adulteration (eg the recent Sudan Red Scare), misrepresentation (eg olive oil scandal exposed in 2001) and the misuse of edible frying oils by the fast-food sector.

“One of the basic rights of consumers is the right to safe food. Consumers must be protected against foods and food production processes which are hazardous to their health. Sufficient guarantee of the safety of all food products and food production processes should be implemented. It does not help to have adequate food standards and legislation and there is no manpower to do the necessary investigation or monitoring,” said Mrs Wilken.

The South African Fryer Oil Initiative (SAFOI), under the auspices of the UFS Department of Microbial, Biochemical and Food Biotechnology, currently monitors edible oils in the food industry and makes a seal of quality available to food distributors.

“Last week’s decision to implement the quality-monitoring system implies that we will now be involving also other departments in the UFS Faculty of Natural and Agricultural Sciences who are involved in various aspects of the food chain in an endeavor to implement this quality monitoring system,” said Prof Herman van Schalkwyk, Dean: Faculty of Natural and Agricultural Sciences at the UFS and one of the main speakers at the workshop.

Prof van Schalkwyk said that the main aim of such a system will be to improve the competitiveness of the South African food industry. “It is clear that the role players attending the workshop are serious about consumer service and that they agree that fraudulent practice should be monitored and corrected as far as possible. Although some of the food outlets have the capacity to monitor the quality of their food, it may not seem to the consumer that this is an objective process. The proposed external monitoring system would counteract this perception amongst consumers,” said Prof van Schalkwyk.

The workshop was also attended by representatives from SAFOI and Agri Inspec, a forensic investigation company collaborating with inter-state and government structures to combat fraud and international trade irregularities.

Agri Inspec has been working closely with SAFOI for a number of years to test the content of edible oils and fats. “Extensive monitoring and control actions have been executed in the edible oil industry during the past four years to ensure that the content and labeling of oil products are correct. Four years ago almost 90% of the samples taken indicated that the content differed from what is indicated on the label. This has changed and the test results currently show that 90% of the products tested are in order. However, to maintain this quality standard, it is necessary that quality monitoring and educational campaigns are continuously performed,” said Mr Joe Hanekom, Managing Director of Agri Inspec.

“The seal of quality presented by SAFOI should also be extended to include all the smaller oil containers used by households,” Mrs Wilken said.

The SAFOI seal of quality is currently displayed mainly on some oil brands packed in bigger 20 liter containers, which include sunflower oil, cottonseed oil, palm oil etc which are used by restaurants and fast food outlets. “Any oil type is eligible to display the seal when meeting certain standards of authenticity. In order to display the seal, the distributor must send a sample of each oil batch they receive from the manufacturer to SAFOI for testing for authenticity, ie that the container’s content matches the oil type described on the label. This is again double checked by Agri Inspec, which also draws samples countrywide from these certified brands from the end-user (restaurant or fast food outlets). If in breach, the seal must be removed from the faulty containers,” said Prof Lodewyk Kock, Head of SAFOI.

“It should however be taken into account that oils without a seal of quality from the UFS can still be of high quality and authentic. Other external laboratories equipped to perform effective authenticity tests may also be used in this respect,” said Prof Kock.

“It is also important to realise that any oil type of quality such as sunflower oil, cottonseed oil, palm oil etc can be used with great success in well controlled frying processes,” he said.

Further discussions will also be held with the Department of Health, the SA National Consumer Union and Agri Inspec to determine priority areas and to develop the most effective low-cost monitoring system.
