多伦多家居自来水有部分含铅量超标2000倍。互联网


水质专家认为,有报告指多伦多食用水危害健康,13%家庭自来水属高危超标并不是危言耸听。这是一个历史遗留的问题,因为城市部分地下食水管,都是由重金属铅造成,在长年累月下导致食水出现安全问题。

认可水质专家赵文杰指出,市政府已经寻求解决方法,在目前情况下,最简单亦算有效的方法,就是每天早上开水喉沖水约5分钟,才饮用第一杯冻水;减低家居自来水风险的方法,可考虑安装过滤器或装置软水系统。

  日日吞铅会血中毒

赵文杰表示,多伦多家居水喉自来水一直存在很多危害健康问题,只不过到现时才高调地浮出来。因为自50年代前至90年代初,城市基建中的食用水地下水 管,长久以来都是用铅管输送食用水到每户每家的水喉。市政府用铅水管是因为铅管软度低,接焊容易,不易损坏。但铅是重金属有毒物质,如积存在人体内是不会 排放出来的。

  赵文杰表示,经过使用数十年的铅水管,当然会有剥落,或铅的残积产生,再经过家居水喉,食用水自然含有铅的成份,如果是在旧区情况可能更见严重,市民 开水喉饮水,亦相当于日日将铅吞下肚。日积月累会危害健康,严重的可能会带来肾病、血液中毒,影响中枢神经,小孩会有过度活跃症等。所以自90年代后,市 政府的地下食水管已经禁止采用铅管,由其他物料如胶管等取代。

  其实,多市政府于10多年前知道食用水有问题,曾鼓励市民在水喉装上符合水质工会规定的水质标准滤水器(NSF53)、或纯水(软水)系统(NSF58)。因为软水可以透过离子交换(ION),有效过滤重金属铅的成分,保障市民健康。

  装滤水器减低风险

赵文杰表示如不装置滤水器或滤水系统,暂时治本方法是每日早上在饮第一杯水前,先开水喉让水流大约5分钟后﹐才饮第一杯开水(不是热水)。目的是让残 留在水管或水喉内的沉淀物质、有毒物质或细菌沖走。如果遇上市府要维修或更换地下水管,更要开水喉先沖水15分钟以上,才饮下第一杯水。另外,市民要时常 沖洗自家水喉的内置过滤网,减少风险。

What we tested
Using ICP-MS instrumentation (see lab videos here), we tested these water filters for their ability to remove toxic heavy metals and elements which have radioactive isotopes.

Specifically, we tested for removal of:

* Aluminum
* Copper
* Arsenic
* Strontium
* Cadmium
* Cesium
* Mercury
* Lead
* Uranium

Why didn't we test for fluoride removal? Fluoride is an extremely difficult element to work with due to its high reactivity (which is one reason why you probably shouldn't drink it). It is also very difficult to remove from water. Testing fluoride concentrations via ICP-MS requires a complicated process run separately from other elements, using different matrix solutions and different plumbing for the instrument.

How we tested for heavy metals removal
To conduct the tests, we created a multi-element "spike" solution containing from 1300 ppb to 2300 ppb concentrations of each of the tested elements. This spike solution consisted almost entirely of laboratory-grade water (DI water), with a very small fraction (less than 0.1%) of laboratory acids found in element standards for the purpose of matrix stabilization.

For each water filter, we first ran several cycles of pure water through the filter in order to "flush" it and pre-load the filter cartridge with purified laboratory water. Once that was complete, we loaded each water filter pitcher with the spiked solution containing the multiple elements listed above.

After the water passed through the filter and was emptied into the holding section at the bottom of the pitcher, that filtered water was then sampled with a clean pipette, weighed on a calibrated laboratory scale and prepped for ICP-MS analysis.

Each sample was run via ICP-MS using a variety of quality control methods, including the use of calibration checks during the run and a four-point calibration curve for each element. Keep in mind that our ICP-MS instrumentation is far more accurate and sensitive than labs running ICP-OES. In fact, we have had to correct other labs using ICP-OES who discovered their calibrations were way off. The Natural News Forensic Food Lab is in the process of ISO 17025 certification.

What we did NOT test for
We did not test for removal of PCBs, pesticides, chlorine or other organic compounds. Accordingly, we cannot reach any conclusions on how well these filters might work on removing those substances.

Testing for those complex molecules would require additional instrumentation which we do not yet have in our lab. (Remember, the Natural News Forensic Food Lab is entirely self-funded and receives no grant money from the government.)

Performance overview
What shocked me the most about the results of this testing is just how poorly most water filters performed on the removal of toxic heavy metals.

Most of the water filters we tested were entirely unsatisfactory in terms of heavy metals removal, in my informed view. Only two filters showed results which I would consider to be sufficient. Most filters also appeared to perform very poorly for removal of elements with radioactive isotopes (uranium, cesium, strontium).

Here's an overview of what we found, element by element:

Aluminum removal
Four of the seven filters tested here actually increased aluminum concentrations in the filtered water.

This indicates they are using a filtration media which contains aluminum and allows some amount of aluminum to enter the water stream during filtration.

Only one filter removed 100% of all aluminum (Zero Water). See full results here.

Copper removal
Copper removal ranged from a low of 8.6% to a higher of 99.1%.

The average copper removal rate was 44.8%.

Copper is associated with mental insanity if consumed in very high quantities. Many homes still contain copper pipes, causing copper contamination of tap water.

Arsenic removal
Arsenic removal ranged from 12.1% to 99.3%, with an average removal of 42.6%.

Arsenic is a cancer-causing metal that's linked to cancer and organ damage. It's a common contaminant in well water. Click here to see full results on arsenic removal.

Cadmium removal
Cadmium is a toxic heavy metal which can cause kidney damage, heart damage and hardening of the arteries.

Cadmium removal ranged from 6.6% (Brita) to a high of 99.2% (Zero Water). The average removal was 33.1%.

Mercury removal
Mercury is an extremely toxic heavy metal that can cause brain damage, kidney damage and reproductive damage.

Because mercury is a "sticky" element, it's the easiest to remove of all. Removal rates ranged from 62.4% (Culligan) to a high of 99.7% (Waterman Mini).

Average mercury removal across all the filters was 88.5%.

Lead removal
Lead is a toxic heavy metal that causes brain damage and organ damage in the human body. Natural News has found significant quantities of lead in Organic Rice Protein superfoods imported from China.

Lead removal ranged from a low of 14.1% (Brita) to a high of 93.7% (Waterman Mini).

Average lead removal was 52.5%.

Strontium removal
In its non-radioactive form, strontium is a bone-building nutrient that's often found with calcium.

Some water filters removed almost no strontium (Brita and Mavea), while the Zero Water Filter removed 100% of strontium.

One filter, the Waterman mini, increased strontium concentrations in the resulting water, indicating use of strontium in the filter media. This is not a bad thing. Strontium is actually a nutritive mineral, much like calcium.

Cesium removal
Cesium removal is important to consider due to the Fukushima disaster and the radioactive fallout of Cesium-137.

I am intimately familiar with cesium binding and removal technologies, as I invented the patent-pending Cesium Eliminator dietary supplement that binds with and captures radioactive isotopes of cesium.

In our testing of water filters, cesium removal varied from a low of 9.5% (Brita) to a high of 100% (Zero Water).

Average cesium removal was 35.3%.

Uranium removal
Removal of uranium is crucial for those planning on surviving a nuclear accident or nuclear war. Following nuclear events, uranium and cesium both fall out of the sky in radioactive forms, settling on bodies of water which are used for irrigation and public water supplies.

Removing radioactive uranium isotopes from drinking water is a crucial survival strategy following a nuclear incident. Only two filters we tested showed an ability to remove substantial amounts of uranium: Zero Water and the Waterman Portable Alkaline Water Purifier.

Click here to see actual results and uranium removal rates for all filters.

Magnesium mineralization
Two water filters we tested substantially increased the level of magnesium in the filtered water. The highest water mineralization rate was achieved by the Waterman mini filter, which is advertised as creating "alkaline water."

The claim is true. While the magnesium concentration of the water we poured into the water filters was only 1.3 ppm, the Waterman Mini increased the magnesium concentration of the resulting water to nearly 250 ppm.

This is a substantial increase in magnesium concentration. The Seychelle filter also increased magnesium concentrations to nearly 250 ppm, indicating it has a "mineralization" component in its filter cartridge.

Recommendations and conclusions
Based on the laboratory analysis completed here at Natural News, I can only recommend two water filters in the category of countertop "pitcher" filters.

Natural News does not sell any of the water filters tested here, but they are available at retailers like Amazon.com. If you wish to help support our non-profit efforts to conduct more testing, please click this Amazon Smile link before shopping on Amazon.com, and Amazon will donate 0.5% of your purchase price to the non-profit Consumer Wellness Center.

The two filters I recommend are:

1) Zero Water
2) Waterman Mini

Heavy Metals Defense - a breakthrough in dietary self defense
In addition to researching the removal of toxic heavy metals in water filters, I've also pioneered extensive, original research into heavy metals contamination of foods, superfoods and dietary supplements.

From this research, I was able to invent a patent-pending dietary supplement formula called "Heavy Metals Defense" which binds and captures toxic heavy metals during digestion.

This formula is laboratory validated to reduce heavy metals by the following factors:

Aluminum reduction: 98.7%
Arsenic reduction: 77.6%
Cadmium reduction: 98.5%
Copper reduction: 95.8%
Lead reduction: 99.9%
Mercury reduction: 92.9%
Uranium reduction: 76.5%

Click here to view the full laboratory results data on Heavy Metals Defense and see how it works.

Essentially, Heavy Metals Defense works in a very similar way to the "ion exchange membrane" of the Zero Water filters. That's why the metals capturing capacity is so high.

以我们十几年工业水处理的经验,感觉小和尚推荐的两款东西,效果并不会太理想,就是便宜而已
去重金属,还是装小型家用机吧(国内很多选择)
先软化(树脂交换),再反渗透或纳滤

小型家用机对于一个人来说,有点浪费,
以前用一人高的滤芯,一年也要换两次,
要求一至两年换,但实际还是担心,
这个零水牌,一年换六次左右。

如果大小是优先考虑的因素,家用机确实稍大,但是可以搁在sink底下,加个Tap,方便!
一家四口都能满足,
不过你选的两款都是浸入式的,不用脱盐,没有废水,如果一个人使用(出水量不大)加上你们上海水况还行,去余氯足以,但去重金属,没效果
