Environmental exposure to asbestos fibres before and after removing asbestos cement roofs from two townships in Gauteng

Authors: GE Mizan, JI Phillips and T Nthoke Source: Occupational Health Southern Africa. Vol 24 No.5 Sept/October 2018 Summary: Background: Despite the banning of asbestos in 2008, South Africa has a legacy of asbestos-containing materials (ACMs) extant in the environment. The number of asbestos cement (AC) roofs in the residential and industrial sectors is unknown but, in the low-cost housing sector alone, it is estimated that there are over one million. Eventually, these roofs will need to be replaced, using […]

Particle Toxicology and health- where are we?

Author(s): M. Riediker, D. Zink, W. Kreyling, G. Oberdorster, A. Elder, et al. Source: Particle and Fibre Toxicology (2019) 16:19 Abstract: Background: Particles and fibres affect human health as a function of their properties such as chemical composition, size and shape but also depending on complex interactions in an organism that occur at various levels between particle uptake and target organ responses. While particulate pollution is one of the leading contributors to the global burden of disease, particles are also […]

Occupational contact urticarial and early-onset work-related asthma in a latex-allergic woodworker exposed to obeche wood

Authors: D Ngajilo, T Singh, E Ratshikhopha, M Jeebhay Source: Current Allergy & Clinical Immunology. December 2018 Vol 31, No4 Summary: Exposure to wood dust has been shown to cause allergic skin and respiratory symptoms in woodworkers. We describe a case of a 53-year-old latex-allergic woodworker presenting with work-related contact urticarial and subsequent upper and lower symptoms associated with obeche wood (Triplochiton scleroxylon) exposure. Clinical evaluation of the patient was suggestive of an early-onset, work-related asthma and latex allergy with […]
