南宁市售瓶装水中微囊藻毒素调查及初步健康风险评价
Determination and preliminary health risk assessment of microcystins in bottled water in Nanning
摘要
Abstract
Objective:To quantify microcystins (MCs:MC-LR,MC-RR,MC-YR) in bottled water in Nanning and to conduct a preliminary health risk assessment.Methods:31 bottled water sold at major representative supermarkets in Nanning in September 2017 were collected.The water samples were cleaned and enriched by solid phase extraction (SPE) using C18,and the three typical MCs,MC-LR,MC-RR,and MCYR were quantified by high performance liquid chromatography (HPLC).A preliminary health risk assessment was conducted.Results:MCs were detected in 31 kinds of bottled water,and the content ranged from 0.05 to 17.05 ng/L.MC-RR was the main component.No significant difference was found in the MCs concentration between mineral water and pure water,domestic and imported mineral water (P ＞ 0.05).The level of individual health risk of bottled water ranged from 0.13 × 10-6 to 43.72 × 10-6/a,and were lower than the maximum allowance level recommended by ICRP and US EPA.Conclusion:The measured concentrations of MCs in bottled water did not exceed the national standard.关键词
