Health risk
It's not known if consuming microplastics poses a serious health risk, but the World Health Organization (WHO) warns that the smallest fragments are likely to be taken up biologically.
健康风险
目前尚不清楚食用微塑料是否会造成严重的健康风险，但世界卫生组织 (WHO) 警告称，最小的碎片很可能会被生物吸收。
Safety
Both tap water and bottled water are safe to drink in most developed countries. However, tap water is treated with proven technologies, including filtration, disinfection, and detention.
Tap water contaminants
Tap water can contain lead and copper from household pipes, taps, and fittings.
自来水污染
自来水中可能含有来自家用管道、水龙头和配件的铅和铜。
Sydney tap water has faced a number of issues, including:
Chemicals
Sydney tap water contains disinfectants like chlorine and chloramine, as well as fluoride for dental health. Trace amounts of heavy metals like lead, copper, cadmium, and arsenic may also be present. In June 2024, Sydney Water detected low levels of perfluoroalkyl and polyfluoroalkyl substances (PFAS), also known as "forever chemicals", in some of its water filtration plants. The levels were higher at the Cascade Dam in the Blue Mountains and North Richmond. However, health authorities have said that Sydney's water is safe to drink and meets Australian government guidelines.
Disease-causing organisms
Cryptosporidium and Giardia have been detected in Sydney's water distribution system. While no increase in disease has been identified, the Sydney Water Inquiry has concluded that further disinfection technologies may be needed.
Taste and odor
Drinking water may have a metallic or chlorine taste or odor due to the chlorine added to kill germs. This is harmless and the taste and smell should disappear if you let the water stand in a jug for about an hour or keep it in the fridge.
悉尼自来水面临许多问题，包括：
化学品
悉尼自来水中含有氯和氯胺等消毒剂，以及用于牙齿健康的氟化物。还可能存在微量的重金属，如铅、铜、镉和砷。2024 年 6 月，悉尼水务公司在其一些水过滤厂中检测到了低浓度的全氟烷基和多氟烷基物质 (PFAS)，也称为“永久化学物质”。蓝山和北里士满的卡斯卡德大坝的含量更高。然而，卫生当局表示，悉尼的水可以安全饮用，符合澳大利亚政府的指导方针。
致病生物
在悉尼的供水系统中检测到了隐孢子虫和贾第鞭毛虫。虽然没有发现疾病增加，但悉尼水务调查得出结论，可能需要进一步的消毒技术。
味道和气味
饮用水可能会有金属味或氯味，因为添加了氯来杀死细菌。这是无害的，如果你把水放在水壶里大约一个小时或放在冰箱里，味道和气味就会消失。 |
