This study quantifies the present-day global and regional distributions (2010–2014) trends (2000–2014) for five ozone metrics relevant short-term long-term human exposure. These metrics, calculated by Tropospheric Ozone Assessment Report, are: 4th highest daily maximum 8-hour (4MDA8); number of days with MDA8 > 70 ppb (NDGT70), SOMO35 (annual Sum Means Over 35 ppb) two seasonally averaged (3MMDA1; AVGMDA8). were explored at monitoring sites worldwide, which classified as urban or...
In support of the first Tropospheric Ozone Assessment Report (TOAR) a relational database global surface ozone observations has been developed and populated with hourly measurement data enhanced metadata. A comprehensive suite products including standard statistics, health vegetation impact metrics, trend information, are made available through common portal web interface. These form basis TOAR analyses focusing on human health, vegetation, climate relevant issues, which part this special...
A D-grade type coal was burned under simulated domestic practices in a controlled laboratory set-up, order to characterize the emissions of volatile organic compounds (VOCs); namely, benzene, toluene, ethylbenzene, and xylenes (BTEX). Near-field concentrations were collected shack-like structure constructed using corrugated iron, simulating traditional house found informal settlements South Africa (SA). Measurements carried out Synspec Spectras GC955 real-time monitor over three-hour burn...
Diesel fuel is known to emit pollutants that have a negative impact on environmental and human health. In developing countries like South Africa, attendants are employed pump for customers at service stations. Attendants refuel vehicles with various octane unleaded fuel, lead-replacement petrol diesel daily basis. risk adverse health effects associated the inhalation of volatile organic compounds released from these fuels. The include benzene, toluene, ethylbenzene xylenes (BTEX), which...

The windy season brings numerous community complaints for gold mining companies situated in the Witwatersrand due to windblown dust from partially rehabilitated tailings storage facilities (TSFs). For communities encroaching onto TSFs, is perceived as a health hazard and an environmental challenge. In study conducted 2017 by Lawyers Human Rights, of mine village facility 6 (TSF6) other surrounding which are be socio-economic threat. Since 2013, when nearby company was liquidated, this has...
Abstract Medical tourism is a well-established sector in developing countries, and attracts significant number of tourists from developed countries. strong driver economic growth, but some argue that this kind promotes inequality terms access to healthcare facilities both Whilst research has been conducted on medical travelling South Africa, no focused the geography Africans abroad for tourist activities. This study therefore sought obtain first-hand information Indian-South African citizens...
South Africa remains an uncharted realm in terms of marine mobile emissions inventory and hence the impact pollution from ships coastal cities unknown. Such a void creates uncertainties about extent population exposure to ships, health economic value associated with changes policies for port city Durban. This study was aimed at estimating benefits improvement air quality within Durban, which is under eThekwini municipality. The particulate matter less than 2.5 10 μm (PM2.5 PM10) sulphur...

In developing countries land-filling is the most common form of waste management that practiced.Landfills are known to be anthropogenic sources air pollutants have a negative impact on both environmental and human health.People who work landfill sites particularly at risk adverse health effects associated with inhalation hazardous (HAPs), such as volatile organic compounds (VOCs).Although VOCs only make up between 0.5% 1% total gas, they important due high level toxicity them.Regular quality...

Mining is important for the South African economy, as it many developing nations. In 2017, mining was reported to contribute 6.8 % GDP and provided more than 460, 000 jobs. Though adds an enormous amount of value country, has significant impacts on environment socio-economic factors society. The well-documented environmental impact operations surface groundwater systems, known Acid Mine Drainage (AMD), just one these impacts. There are also other such pollution agricultural soils, creation...
Public transport systems in Johannesburg, South Africa, rely on a large number of diesel-powered buses. These buses are fuel economical and durable. However, filling station attendants, bus drivers the public exposed to diesel fumes associated with them. Fuel attendants exhaust fumes, as well emissions from pumps daily basis, at risk adverse health effects inhalation volatile organic compounds (VOCs) released. The VOCs released include benzene, toluene, ethyl-benzene xylenes (BTEX), which...
Air pollution and climate change threaten Africa’s development because of their negative impacts on human health, well-being productivity. reduce agricultural productivity, for example, with implications food nutritional security. Two the biggest issues African countries are lack data emissions causing air change, inadequate policy implementation capacity. Countries need this to plan policies that can deliver national priorities goals. Ozone as an anthropogenic greenhouse gas...
<title>Abstract</title> High emissions of volatile organic compounds (VOC) pose a serious health risk, including cancer. The Environmental Protection Agency (EPA) and the World Health Organization (WHO) list these substances as hazardous air pollutants (HAPs). Air travel airport operations are major contributors to VOC emissions. Within VOCs, group referred BTEX (i.e. benzene, toluene, ethyl-benzene xylenes) several implications on exposure. Therefore, monitoring concentrations at settings...
Abstract This study examines the dynamics of networks among informal recyclers in Fietas, Johannesburg, South Africa, focussing on how these embody their struggle for "Right to City." By observing recycling activities across various Johannesburg suburbs, highlights not only provides livelihoods unemployed but also allows marginalised groups assert presence and rights within cityscape. Building upon Adama's (2012) analysis urban social networks, this research explores interactions spatial...
Landfills produce pollutants that negatively impact humans and the environment.In developing countries such as South Africa, landfilling is most common form of solid waste management.People living in close proximity to landfills are particularly at risk harmful volatile organic compounds (VOCs).Although VOCs only constitute ~1% landfill gas (LFG) emissions, they concern associated with these high.Of particular within VOCs, BTEX group (viz.benzene, toluene, ethyl benzene xylenes).These wind...
