BRIEFING MINISTER – HEALTH STUDIES IN THE DECLARED PRIORITY AREAS Climate Change and Air Quality
POLICY FRAMEWORK • The Air Quality Act of South Africa is pivoted on the Bill of Rights contained in the Constitution; • Section 24 of the Constitution states that everyone have a right: - environment that is not harmful to their health; - prevent pollution and ecological degradation; - promote conservation and - secure ecologically sustainable development and the use of natural resources while promoting justifiable economic and social development;
POLICY FRAMEWORK & STRATEGY STRATEGY TO ADDRESS AIR POLLUTION IN DENSE LOW-INCOME SETTLEMENT • Establish a coordinating structure, the national coordination committee on residential air pollution; • Ensure through the NCC, that interventions aimed at reducing air pollution in dense low-income settlements are effectively prioritized; • Provision of affordable or subsidised clean energy initiatives; • Ensure that low income household are energy efficient; • Influence development planning initiatives to take into account air quality; • Encourage social upliftment programmes with air quality benefits; • Create public awareness on air pollution; • Monitoring and evaluation and reporting
Priority Areas The Minister of Environmental Affairs has to date declared three (3) National Priority Areas in terms of Section 18(1) of the National Environmental Management: Air Quality Act, 2004 (Act No. 39 of 2004) (AQA) namely, the: • Vaal Triangle-Airshed Priority Area (VTAPA) in 2006, • Highveld Priority Area (HPA) in 2007, and • Waterberg-Bojanala Priority Area (WBPA) in 2012. The declaration of the VTAPA and the HPA came about as a result of poor air quality due to industrial activities, domestic fuel burning, waste burning, and mining activities in these areas. The WBPA declaration was in line with the precautionary principle of the National Environmental Management Act (Act No. 107 of 1998) due to planned developments for the area.
Priority Area Structures As part of the implementation of the Priority Area (PA) Air Quality Management Plan (AQMP) as required by Section (19)(6)(c) of the Air Quality Act, the Department has established the Multi-Stakeholder Reference Groups (MSRGs) and Implementation Task Teams (ITTs) for each priority area. These structures consist of representatives from: • Relevant national departments, affected provincial department, district and local municipalities, • Non-Government Organisations and Community Based Organisations • Industries, • academia, • Interested and affected parties identified during the implementation of the Air Quality Management Plan.
Priority Area Structures The Multi-Stakeholder Reference Groups and Implementation Task Teams play a crucial role in the implementation of each of the priority area Air Quality Management Plans. They do this by: • Creating a platform for stakeholders to share information and to report on their air quality management, interventions, performance, practices, strategies, and goals to other stakeholders, • Enabling government, industries, non-governmental organisation and other stakeholders to maximize opportunities for improving and leveraging available resource, • Establishing a mechanism for an improved understanding of stakeholder’s priorities and to respond to emerging stakeholder concerns • Providing a platform for stakeholders to discuss priority issues together, thereby building trust and promoting collaboration through dialogue.
Projects A number of projects have been implemented by the Department in collaboration with stakeholders since the declaration of the first priority area. Below are some of the projects: • Health Studies • Source Apportionment Study • Air Quality Awareness Fun Run • Air Quality Offset projects • Alternative fuels pilot project • Tyre management project
VTAPA HEALTH STUDY • The study consist of three parts namely: • Human health risk assessment (HHRA) • Community health survey • Child respiratory health survey
HUMAN HEALTH RISK ASSESSMENT • HHRA • Desktop study: Based on the prevailing ambient air quality in the area, what is the level of risk (with respect to each pollutant) • Uses Hazard quotient (HQ) as a measure of relative risk • HQ of 1 and above indicates the potential for adverse heath effects
HHRA RESULTS Areas around Diepkloof are at relatively higher risk for NO2
HHRA RESULTS Areas around Sebokeng, Sharpville and Zamdela are at relatively higher risk for PM10
HHRA RESULTS • Human Health Risk Assessment • SO2 (hourly and daily standard) - unlikely to pose any health risk. SO2 standards are generally being met.
HHRA - VULNERABILITY ASSESSMENTS • Vulnerability assessment • Vulnerability was assessed using population sensitivity (children and elderly) and socio-economic status(the unemployed, living below the poverty level of R400 per person per month and people who live in informal houses) • The most vulnerable sub-places are those with a vulnerability score of 6 and above
Vulnerability Assessment - RESULTS • Most vulnerable people are those situated in the Diepkloof, Evaton, Zamdela, and Sharpeville spheres of influence
COMMUNITY SURVEY • Approach • Household survey using questionnaires to determine association between health endpoints and air pollution • The study was conducted in Zamdela, Sharpeville, Sebokeng and Diepkloof within a 3km radius of the monitoring station • Total households were 1 219 : 319 in Diepkloof, 337 in Sebokeng, 277 in Sharpeville and 286 in Zamdela • Study looked at acute and chronic health outcomes
COMMUNITY SURVEY – ACUTE HEALTH OUTCOMES The prevalence of acute health outcomes for individuals were all below 5% • The highest prevalence of bronchitis (0.3%), and ear infection (1.85%) was recorded for Diepkloof • The highest prevalence for hay fever(2.5%) and sinusitis (1.6%) was recorded for Zamdela
HEALTH OUTCOMES The prevalence of illnesses were relatively low – not different from country-wide prevalence • Highest prevalence bronchitis was 0.4% (Diepkloof) • Highest prevalence of asthma was 1.41% (Zamdela) • Highest prevalence of TB was 1.85% (Sharpeville) • Highest prevalence of cancer was 0.69% (Sharpeville • Highest prevalence of hospitalization for lung infection was 0.37% (Sebokeng) • Highest prevalence of cough/night sweat was 3.6% in (Diepkloof &Sebokeng) • Highest prevalence of TB was 2.5% in (Diepkloof) ***Interpretation of these results is limited due to the unavailability of hospital/clinical records
CHILD RESPIRATORY HEALTH STUDY • Targeted school children: Grades 3-6 children (8-12yrs old) - Sebokeng, Sharpeville, Zamdela and Diepkloof • Performed lung function test [peak expiratory flow (PEF) and forced expiratory volume (FEV)] • Number of respondents was 282 (82% of selected sample)
RESULTS: QUESTIONNAIRES ON CAREGIVETRS • The prevalence of doctor-diagnosed asthma was 3.6% • (The Durban respiratory health study had a prevalence of 29 - 35%)
RESULTS: AIR POLLUTION VS RESP HEALTH There was no relationship between pollution changes and FVE (deep breath measurements)
RESULTS: AIR POLLUTION VS RESP HEALTH There was a relationship between pollution changes and PEFR (maximum normal breath) for PM 2.5 only
RESULTS: AIR POLLUTION VS RESP HEALTH There was a relationship between pollution changes and the odds of getting a cough
HIGHVELD PRIORITY AREA (HPA) HEALTH STUDY The Department has initiated a health Study in the Highveld. Similar to the VTAPA health study • The study will be undertaken in • Mpumalanga • Emalahleni • Secunda • Middleburg • Ermelo • Gauteng province • Etwata • Tembisa
HPA HEALTH STUDY Challenges: • Although all departments in Mpumalanga have provided support; • The Gauteng Department of Education and Gauteng Department of Social Development are not in support of the study • This has caused delays to the study that was supposed to have commenced in January. Solution: Proceed without the inclusion of Gauteng Schools
CONCLUSION • Risk factors for respiratory illnesses related mostly to energy use (coal for cooking and paraffin for heating), overcrowding and hygiene practices (burning or burying of refuse or failure to regularly remove refuse) as well as lifestyle (active and passive smoking and alcohol use; • The main vulnerable areas of concern were those north of the Sebokeng and Sharpeville monitoring stations and south-east of the Zamdela monitoring station; • There is reason for concern that air pollution in the VTAPA may be affecting children’s health; • Study is regarded as a baseline study and it will thus be beneficial to reproduce it in other similar areas;
