Differences in uptake of 14nm PEG-liganded gold nanoparticles in BEAS-2B cells is dependent on their functional groups

Authors: Melissa Vetten and Mary Gulumian Source: Toxicology and Applied Pharmacology 363 (2019) 131-141 Summary: Abstract: Physico-chemical characteristics of nanoparticles have been shown to alter the uptake and toxicity of nanoparticles. This study investigated the uptake of six gold nanoparticles (AuNPs) into the human bronchial epithelial cell line BEAS-2B. The AuNPs studied included colloidal citrate-stabilised AuNPs of 14 nm in diameter; and 14 nm AuNPs conjugated to functional groups via polyethylene glycol (PEG), namely hydroxyl-PEG (POH), carboxyl-PEG (PCOOH), biotin-PEG (PBtn), […]

Ambient PM10 and Respirable Dust Levels Near Gold Mine Tailings Storage Facilities in South Africa

Authors: Charlene Andraos, Kobus Dekker, and Mary Gulumian Source: Clean- Soil, Air, Water 2018, 1800103; DOI: 10.1002/clen.201800103 Summary: Gold mine tailings storage facilities (TSFs) contribute largely to high dust levels in the Gauteng and North-West provinces, South Africa, and are seen as a public health concern. Currently, the South African National Ambient Air Quality Standard for PM10 is 75 μgm_3 (24 h) and no limits have yet been set for respirable PM4 levels. This study investigates the ambient PM10 levels […]

Awareness of health and safety responsibilities among contract cleaning working

Authors: WF Mudenha, M. Chadyiwa, N. Naicker Source: Occupational Health Southern Africa, 2018 Vol. 23 No. 6 Nov/Dec. Summary: Abstract: Background: Five employee health and safety responsibilities are outlined in Section 14 of the Occupational Health and Safety (OHS) (Act No. 85 of 1993). All employees must be aware of these in order to protect their health and safety at work. Objective: This study aimed to assess if contract cleaning workers are aware of their health and safety responsibilities as […]
