This study was concerned with establishing the extent to which various components of the environment were exposed to the three toxic minerals, arsenic, mercury and lead. The concentration of these three elements were determined in groundwater and surface water, soil, plants, animals such as goats, and humans in potentially contaminated areas in the Limpopo Province of South Africa. The focus of the study was to assess the possible exposure to infants through ingestion to arsenic, mercury and lead. Comparison of the mineral content of water at the study sites with international and national drinking water standards, indicated water from Rooiberg, Leeupoort and Gravelotte are not fit for human consumption due to high arsenic and lead concentrations. Water at Gravelotte also has unacceptably high levels of mercury. The soil, plants, goat’s milk and mother’s milk at Rooiberg have higher levels of arsenic and lead than have been recorded for many other countries. Mother’s milk and goat’s milk are the main sources of arsenic, lead and mercury contamination at Rooiberg. It is therefore newborns and toddlers who are most at risk from exposure to arsenic and lead. This is a cause for environmental and health concerns, but as this research is only a base-line study, it is imperative that more comprehensive surveys of potentially toxic mineral contamination be conducted in the province. / Environmental Sciences / (M.Sc.

M.Sc (Aquatic Health) / There has been a recent onslaught of water quality problems in South Africa, with many believing that South Africa is nearing a water crisis in the not so distant future. A Regional Scale Risk Assessment was conducted on the Koekemoer Spruit in order to validate the use of such a risk assessment in the management of small catchments. During the study the use of Artificial Mussels (AMs) in the bio-monitoring of metals were also validated. The Regional Scale Risk Assessment methodology created by Landis (2005) was used during the study. Various lines of evidence were used during the risk assessment process: water quality analysis, invertebrate assessments, diatom assessment and AM and snail assessments. It was found that the Koekemoer Spruit has an impact on the Vaal River with regards to some water quality aspects, especially with regards to an increase in nitrates. It was found that a significant (p<0.05) correlation exists between AMs and Melanoides turbiculata with regards to As, U, Se and Co accumulations. Gold mining was identified as a major stressor source within the system. Other notable sources of stressors within the system included agricultural activities and a golf course. The environment was found to be the endpoint that is at highest risk from the various sources within the system. The in-stream habitat was found to have the highest risk compared to the other identified habitats.

Chemical (gaseous) emissions from wastewater treatment plants (WWTP) are perceived as odour and can generate undesirable health reactions. These could affect the quality of life to those regularly albeit intermittently exposed, although regular exposure may result in tolerance and loss of recognition of the odour. Consequently, research is necessary to establish the role of Environmental Impact Assessment (EIA) in ensuring that facilities such as WWTP do not pose a threat to local communities, particularly in relation to housing developments for poor communities. The aim of this study was to investigate if the EIA regulations were effectively implemented before building of the Residential Development Proiect (RDP) houses at KwaMathukuza, in Newcastle South Africa. Furthermore, the study intended to determine the impact the (WWTP) has on the health of people who reside close to the site and to establish if the families staying close to the WWTP have any common ailments such as handicapped babies, early deaths within families. Findings would also indicate if RDP houses should be built in close proximity to such sites. Data was collected through a survey of 85 residents living within five kilometers and ten residing beyond five kilometers from the WWTP. The participants were selected randomly. Municipality employees who worked with the WWTP were also sampled together with healthcare givers. Data included information about health of the community, their perception of the gases released from the WWTP as well as EIA meetings and processes related to the construction of the RDP houses. The outcome of this study revealed that EIA regulations were not adequately implemented and that this residential site was unsuitable for the construction of RDP houses. It emerged that the residence regularly experience unpleasant odours released from the WWTP. These could be associated with ill-health of the residents as well as v degradation the environment in general. The study also found that the effect of the WWTP affects even those communities who reside beyond five kilometers from the WWTP. The researcher argues for more stringent mechanisms to ensure that EIA regulations are properly implemented to prevent adverse effects on the communities. / Environmental Sciences / M. Sc.

MPH / Department of Public Health / Background: Climate change is a universal public health problem that affects developed and developing countries including South Africa. This environmental hazard causes damage of properties, injuries and death. In most cases, survivors experience psychosocial problems such as depression, anger and isolation after flood because of climate change. Purpose: The purpose of the study was to determine health effects of climate change at Ga- Mashamothane village, Fetakgomo Tubatse Municipality, South Africa. Methodology: A quantitative approach using cross-sectional descriptive design was used in this study. A sample of 352 households has been selected from the target population by means of simple random sampling. Self-administered questionnaires with closed-ended questions were administered to respondents between the age of 18 years and above who met the inclusion criteria. Permission to conduct the study was obtained from the Ethics Committee of the University of Venda. Data were analysed using Statistical Package for Social Science (SPSS version 25) and presented in the form of tables, charts and graphs. Chi-square was used to test significant relationship between heavy rainfall and injuries, and between drought and malnutrition. Results: Three hundred and fifty-two (352) questionnaires were distributed to respondents and 258 questionnaires were satisfactorily completed and returned. The findings of the study showed that 177 (68.6%) of the respondents were male and 81 (31.4%) of the respondents were females. The results indicated that heavy rainfall and injuries statistically are significantly correlated (P-value =0.000). There was positive relationship between heavy rainfall and injuries, as majority of the respondents 242 (93.8%) sustained injuries after experiencing heavy rainfall. The results of the study indicated that drought and malnutrition statistically are significantly correlated (P-value =0.000). There was positive relationship between drought and malnutrition, as majority of respondents 225 (87.2%) suffered from malnutrition during drought. Conclusions: The study found that there is association between heavy rainfall and injuries and there is association between drought and malnutrition. Recommendations: There is a need of collaboration of several stakeholders such as local municipality, Department of Health, Department of Agriculture, Department of Labour and department of Basic Education to come up with strategies to protect people’s lives. / HWSETA

Unwanted and unintended pregnancies pose major reproductive health challenges to women throughout the world. Despite the availability of modern contraceptives, many women and men fail to use contraceptives effectively. This research focussed on reasons for not using contraceptives effectively in the Northern Tshwane area of the Gauteng Province of the Republic of South Africa (RSA). Structured interviews were conducted with 83 women and 71 men about their contraceptive practices. Age, religion, educational level and residential areas influenced clients' contraceptive practices. These results were categorised for adult males and females as well as for adolescent males and females. Adolescents encountered problems in accessing contraceptive services. Adult females knew most about traditional contraceptives, although men knew about some of these methods, and adolescents used some of them. All respondents could gain additional knowledge about modern contraceptives. The respondents' knowledge about · emergency contraceptives was extremely limited. Although most respondents knew about legalised choice on.termination of pregnancy (CTOP) services in the RSA, they did not know when nor how to access these services. Nurses working in contraceptive health services, revealed during a focus group discussion that a lack of resources (including shortages of malcondoms, contraceptive injections and oral contraceptives) hampered the quality of services that could be rendered. Of particular concern was the nonavailability of Norplant implants and female condoms. Nurses expressed a need for pecific national policy guidelines about supplying contraception to adolescents. Although most nurses knew about emergency contraceptives, they did not promote its use because they assumed that clients would misuse emergency contraceptives.instead of using contraceptives regularly. The nurses indicated that very few facilities offered CTOP services. The nurses regarded women who obtained repeated CTOPs to be misusing these services and suggested that limitations should be placed on the number-of times any woman could obtain such services. The negative attitudes of community members and of colleagues towards persons working in CTOP services caused hardships for them. Recommendations address ways in which contraceptive services could be improved. / Health Studies / D. Litt. et Phil. (Advanced Nursing Sciences)

Risk taking behaviours such as drug use, sexual activities and tattooing are prevalent in the correctional institutions, including those in South Africa. Such behaviours pose a serious challenge as regards health care of inmates. In particular, these behaviours contribute to the transmission of HIV/AIDS which results in morbidity and mortality. Harm reduction components are employed as effective measure to curb the spread of the pandemic. These components are lauded owing to their considerable impact. They consist of needle exchange programmes, substitution therapy, condom provision and education. Various developing (Morocco, Brazil and Egypt) and developed (Scotland and Canada) countries make use of such components to address risk taking behaviours in correctional institutions. Although condom provision and education have been implemented by the South African Department of Correctional Services in state institutions, there is an urgent need to enhance the efforts. This study investigates the extent of risk taking behaviours amongst inmates at the Leeuwkop Correctional Centre. It also determines the level of knowledge of inmates and staff regarding HIV/AIDS. The researcher employed a qualitative form of methodology, collecting data by means of a structured questionnaire. The data was coded and analysed by means of the Statistical Package for the Social Sciences (SPSS) software. The findings reveal that the risk taking behaviours are prevalent at the Leeuwkop Correctional Centre. Furthermore, the analysis of the knowledge items regarding HIV/AIDS indicates that there are certain deficits that require attention. They are also notable differences in the primary sources of HIV information for inmates and staff. It was found that a dire need exists to enhance and expand current harm reduction initiatives in correctional institutions in order to offer health care services that are compliant with international conventions such as the Dublin Declaration on HIV/AIDS as well as the South African Constitution. Reluctance to do so is tantamount to housing inmates in „de facto‟ death chambers. Hence the augmentation of such initiatives is strongly recommended. / Penology / D. Litt. et Phil. (Penology)

Breast cancer poses a serious public health concern. This case-control study describes the relationship of night-shift working on the development of breast cancer in 57 women diagnosed with breast cancer compared to 49 women with other types of cancer in the Vaal Triangle area (selected through non-probability purposive sampling from CANSA). The study revealed that women who work night-shift developed breast cancer 1.24 times more often than women who do not work nightshift (OR=1.24 [95% CI 0.52 to 2.89]). The odds ratio was further increased in women who worked rotating-shift (OR=1.44 [95% CI 0.58 to 3.59]). Night-shift work exposure was not statistically related to the development of breast cancer. It is recommended that the relationship between night-shift exposure and breast cancer risk be further explored through cross-sectional and cohort studies, and other breast cancer pathways. / Health Studies / M.A. (Public Health)

The main purpose of this study was to explore and describe factors that contribute to young refugee girls (aged 15-19 years) to be engaged in intergenerational sexual relationships in the city of Tshwane. A qualitative, exploratory, descriptive study was conducted using semi-structured interviews. Ten refugee girls were purposively selected using snowballing technique. Powerlessness, increased libido, curiosity, perception of inferior status of the women, attitudes towards assertive women, culture, anonymity, high cost of living, unemployment, poor educational status and residential conditions emerged as the main contributing factors to involvement of young refugee girls in intergenerational sexual relationships. These categories were grouped under three themes namely age, gender inequality and low socio-economic factors. In order to reduce the involvement of young refugee girls in intergenerational sex which increases their risk of HIV infections, the study recommends the initiation and/or improvement of programmes for addressing the three identified themes / Sociology / M.A. (Sociology (Social Behaviour Studies in HIV/AIDS))
