To determine the use of lead-based paint in public playgrounds in the municipalities of Johannesburg, Tshwane and Ekurhuleni.
Forty-nine public parks were selected from the municipalities of Johannesburg, Tshwane and Ekurhuleni. Lead levels in paint on playground equipment were measured in situ using a hand-held Thermo Scientific NITON XLP 700 Series X-ray fluorescence (XRF) analyser.
Playground lead levels ranged from 'too low to detect' to 10.4 mg/cm2. The mean and median lead concentrations were 1.9 mg/cm2 and 0.9 mg/cm2 respectively. Forty-eight per cent of lead paint measurements exceeded the internationally accepted reference level of 1 mg/cm2.
The study shows that lead-based paint is widely used in public playgrounds in the three study municipalities, and most likely throughout South Africa. We suggest key actions to ensure that children's playgrounds in South Africa are lead-free zones, and that childhood lead exposure in these settings is prevented.
确定约翰内斯堡、茨瓦内和埃库鲁莱尼市公共游乐场使用含铅涂料的情况。
从约翰内斯堡、茨瓦内和埃库鲁莱尼市选择了 49 个公共公园。使用手持 Thermo Scientific NITON XLP 700 系列 X 射线荧光(XRF)分析仪现场测量游乐设备上的油漆铅含量。
游乐场的铅含量范围从“太低而无法检测”到 10.4mg/cm2。平均和中位数铅浓度分别为 1.9mg/cm2 和 0.9mg/cm2。48%的含铅油漆测量值超过了国际公认的 1mg/cm2参考水平。
研究表明,含铅涂料在三个研究市的公共游乐场中广泛使用,很可能在整个南非也是如此。我们建议采取关键行动,确保南非的儿童游乐场是无铅区,并防止这些场所的儿童铅暴露。
