Water and Health
Preface
The pollution of water source comes from the secondary
pollution of the conduit pipe of tap water and water tank on
high building. Also it comes from the increase of residual carcinogen
caused by the addition of chorine and disinfection in tap water.
They have threatened our health fearfully. According to the
survey of WHO, it indicates that 80% of disease in the world
and 50% children’s death are relative to bad quality of
drinking water. The digesting disease, infectious disease, various
skin disease, sugar diabetes, cancer, lithiasis and cardiovascular
disease inducing by drinking bad water have been up to more
than 50 kinds. As the water pollution, in the world, 50 million
children die every year, 35 million people suffer cardiovascular
disease, 70 million people suffer lithiasis, 90 million people
suffer hepatitis, and 30 million people die from liver cancer
and stomach cancer.
So “ purifying
water for life, keep the whole family healthy” is the theme
of modern life.
But when we face more and more water filters in
the actual market and various different idea of drinking water,
how do we make a correct choice?
The brochure cites the relative data of authoritative
department and people. It describes the relation of water and
health, and makes a summarily analysis aiming to several different
drinking concepts and water filters. The purpose is to publicize
correct concept of drinking water and using water, in order
to make people know how to protect the health of your family
and yourself, and make sure that you all enjoy healthy life.
Chapter
1: Water and Health
1. Water: the source of life
We can live some weeks without
food. But, no water, after some days, we will die for dehydration.
More 2/3 of human body is water, but most people don’t know
the important of water.
After ingesting sufficient water, some health
problems will be solved or eased, such as asthma, hypersensitivity,
hypertension, high cholesterol, headache, migraine, backache,
rheumatoid arthritis, angina and interval claudication (for
example, clonus caused by lack of blood supply).
Water——common and passed by proper filtration
water——one kind of nutriment being neglected but absolutely
necessary, maybe it is needed component for making you more
healthy, more vigor and longer life, but being lost.
2. Hardness of water, TDS
value
Hardness means the gross amount
of calcium and magnesium or CaCO3 in the water. More CaCO3,
the water is harder. Less CaCO3, the water is softer.
TDS value (total dissolvability solid) is
used for measuring index of all minerals in the water. TDS
value not only includes calcium and magnesium (hard factor),
but also includes zinc, copper, chrome and selenium, etc.
Generally higher hardness of water, TDS value will be higher.
3. Water and heart disease
For many years, many researches
have clued on the relation between drinking water and death
rate of cardiovascular disease. Research shows hardness and
total dissolvability solid are two beneficial factors. They
are related with lower death rate of heart disease.
In 1979, American scientist Comstock after
having summarized 50items research findings gained the following
conclusions: the relativity between hardness of water and
death rate of cardiovascular disease was existent. A mass
of research statistics showed this kind of relativity was
very obvious so that it could not appear incidental or sampling
error.
Today after passing 30years’ research, gained
conclusion is still: drinking soft water is easier to catch
cardiovascular disease than drinking hard water.
American scientists Greathouse and Osborne
researched 4200adults, who was in the range of 25-74old and
distributed in 35different areas. They found death rate of
heart disease in hard areas was lower than that of soft areas.
One report in Oak Ridge national laboratory put forward that
calcium and magnesium in hard water could lower the danger
of heart shock. That research compared the male citizen in
Wisconsin. They drank well water of their own farm and the
result was farmers who drank soft water would have heart disease
but those who drank hard water wouldn’t have problems in
this aspect.
Research approved: ideal drinking water could
make death rate of cardiovascular disease lower 15%. Hardness
of water has specific relation with death rate of heart disease.
We should do our best to drink hard water which hardness is
about 170mg/L. Secondly TDS also has specific relation with
death rate of heart disease. Higher TDS value, heart attack
times will be less. Proper content hardness and TDS in drinking
water are beneficial and compose healthy drinking water.
4. Water and cancer
According to estimation, 60%-80%cancer
is caused by environmental factor. People identically thought
that caner was caused by chemical carcinogen in environment,
so that in the end that could be prevented. Some researches
showed that chemical substance existed in surface water, ground
water and tap water. Furthermore, THM’s (haloform) would
be generated during the process of chlorination treatment
in drinking water.
Amount of chemical substance directly or indirectly
drained into the water is horrendous. Since 1974 there has
been checked organic and inorganic drinking water contamination
surpasses 2100types more in supply system of American drinking
water. 90types among those 2100types contaminations have been
confirmed that they have disadvantaged influence to health,
have carcinogenic, teratogenic and mutagenic functions or
have toxicity.
American scientists analyzed drinking water
of 100 American big cities and found that if there was middle
content TDS (about 300mg/L) in drinking water, which was hard
water, leaning alkalescence (PH> 7.0) and contained 15mg/L
SiO2, then death toll of cancer would be lower 10%~25%.
The full-face conclusion gained through research
is: drinking water with TDS value is about 300mg/L, hardness
is 170mg/L and PH is leaning alkalescence will lower the deadly
fatalness of cancer.
Chapter
2: Water Pollution in Real Life
1. Pollution of water source
After the twenty years of reform
and opening, the economy in our country has develop quickly,
but environmental pollution becomes seriously day by day,
especially the drinking water pollution. According to the
stat of national environmental department, 82% of rivers in
our country have been polluted in different degrees; In the
seven main water systems, 40% of rivers are unsuitable as
drinking water source; 78% of rivers in urban water area are
unsuitable as drinking water source; About 50% of urban ground
water has been polluted. According to the stat data of environmental
health testing station of Chinese preventive medicine academy
of sciences (1997), and evaluate according to actual drinking
water sanitation standard (the standard is equivalent to the
level of developed countries in seventies): 76.1% of people
in our country are drinking water that cannot reach the sanitation
standard. The toxin indexes exceeding 3% of standard are Fe,
Mn, fluoride, nitrite and sulfate etc. There are frequent
reports of endemic caused by drinking water.
It needs to point out specially: the study
of poisonous matters in drinking water has been reinforced
in recent years. More than 10 thousand chemicals have been
inspected in water, and there are more than 100 kinds of carcinogen
or matters that may cause cancer.
2. Pollution of water
pipe net
After tap water leaves factory, it is transported
to thousands of families through water pipe net, water tower
and water tank etc. The aging of water pipe and the deficiency
of cleanliness overhaul of water tank cause the secondary pollution
of tap water, so it is unsafe to drink it directly. According
to the inspection of environmental health testing station in
Chinese preventive medicine academy of sciences, the rate of
reaching the standard in 35 main cities is only 23%.
3. Adding chlorine and disinfection
of water
Adding chlorine to disinfect
drinking water comes in the late 1890’s. Most water factories
are using the method at the moment. Is chlorine in drinking
water an activator to causing atherosclerosis and cancer?
In the book of coronary thrombosis, cholesterin and chlorine
wrote by American M.d. Price in the late of 1960s, he thought
the essential reason causing arteriosclerosis is chlorine.
Nothing can deny the unassailable fact: chlorine is the essential
reason of causing arteriosclerosis and relative disease such
as heart failure and most unexpected death. Chlorine usually
consists in the proceeded drinking water.
Is chlorine related to cancer? During the
chlorination process, chlorine combines with natural organic
matters and humus into latent carcinogen of haloform (THM’s).
Haloform includes carcinogen such as chloroform, bromoform,
carbon tetrachloride and dichloromethane etc.
American biochemist Dr. Herbert Schwartz thought:”
Chlorine is so dangerous, it should be prohibited using. Putting
chlorine into water just likes start-up one time bomb.”
Cancer, heart disease and senilism all those are injury of
mind and body are mostly caused by adopting chlorine treatment
water. It makes us appeared decrepit evidence at young, for
example, arteriosclerosis etc. If the water you drunk is treated
by chlorine, you shouldn’t drink it. You can buy the water
which is worked by high efficient filter and 99% THM’s is
removed or proper water in bottles. Such this simple safeguarding
could prevent thousands upon thousands people catching the
heart disease and cancer which are two primary death killer.
4. Harm of water pollution
According to the investigation
from World Health Organization (WHO), it was made clearly
that 80% sickness and 50% children death have relations with
the harmful water quality of drinking water. There are much
50 diseases are caused by drinking harmful water, which included
digest sickness, contagion, all kinds of dermatosis, diabetes,
cancer, lithiasis, cardiovascular disease etc. Owing to water
pollution, there are 50 millions children death, 35 millions
people catch cardiovascular disease, 70 millions people catch
lithiasis, 90 millions people catch hepatitis, 30 millions
people die of liver cancer and stomach cancer. The harm caused
by water pollution mainly include the points as follows:
1) Water polluted by pathogency microbial
contamination will cause all kinds of contagion, as cholera,
typhoid etc.
2) Water polluted by harmful organic matter
(as phenol, benzene, chloroform, carbon tetrachloride, agricultural
chemicals, synthesize laundry agent etc.), will cause all
kinds of poisoning and sickness.
3) Water polluted by heavy metal (Hg, Pb,
Cu etc.) and other inorganic toxic material(chloride, arsenide,
nitrite etc.), will cause all kinds of poisoning.
Chapter 3. Correct Concept
of Drinking Water and Using Water
1. Pure water
The purified water (desalted
water) contain little or even not mineral substance, can be
attained by distilled, reverse osmosis, ion exchange or the
compound way.
According to the research to the heart disease
and cancer, the healthy water should have certain rigidity
and some amount of TDS, as a result, the purified water, which
men-made soft water without calcium, magnesium, having low
resolvable total solids, is not good for the health.
Compare the animals that drink the hard water
of some harmful substances, such as cadmium, lead, chlorine
or fluorine with the animals that drink the soft water of
same kind of harmful substances, and it turns out that the
harmful substances in the animal that drink the hard water
is less than those that drink soft water. The animal experiment
vividly convinces that the hard water is healthier than soft
water. The hard water restrains the harmful elements (such
as cadmium, lead, chlorine or fluorine), decreasing their
absorption, or that the minerals in the hard water supply
the needed nutriments that preventing the effect of the harmful
substances. The ideal rigidity of the water is about 170mg/L.
However, many people still prefer to drink
the purified water in own consideration. Usually, they may
think that: I know that I should drink water, but the water
that is polluted by the chlorine etc chemical elements and
poisonous metal is not safe enough, so I buy the distillation
and reverse osmosis equipment, which can exclude all the substances
in the water, then the water can be drunken safely. Is it
a right choose?
In fact, the distillation and reverse osmosis
equipment can produce the soft desalted water that doesn’t
contain any profitable minerals, but the effect of harmful
substances in this kind of soft water will be enlarged, the
little harmful substances in the desalted water will have
more negative influences than those of same amount in the
hard water.
Accordingly, due to different reasons, drinking
both polluted and desalted water is bad for our health.
2. Mineral water, magnetic water, active
water and energy water
At present, there are many kinds
of water products, such as mineralized water, magnetic water,
activated water and energy water etc, even the water compounded
with all the above-mentioned functions, which is alleged to
be effective to almost all the diseases.
This is really egregious business dealing.
We can ask:“Had the water been purified? Doesn’t it contain
the harmful substances? Which kind of the purified technology
does it adopt?”
In fact, base on the real condition of water
quality in China, purifying the water to exclude the harmful
substances in the water is urgent to considerate firstly,
secondly, thinking over which kind of technology should be
adopted to keep the profitable mineral microelements in the
water, so as to keep certain rigidity and TDS value.
3. Standard of healthy
water
The standard of healthy water of sparkplug includes
that the water should not contain the organic matter, chlorine,
heavy metal, bacteria, disease etc pollutant, and at the same
time, contain certain amount of rigidity (ideal value is about170mg/L),
certain amount of TDS (the ideal value is 300mg/L) and PH with
more basicity (over 7.0).
4. It is insufficient of
only paying attention to the quality of drinking water.
The research shows that, the pollutant in the
water that flows into body can be divided to: 1/3 is from mouth,
2/3 is from washing and bathing. As a result, in order to take
good care of the health of family member, it needs attach importance
to both drinking and using water. We not only need solve the
problem of drinking water, but also lay stress on the purifying
on the drinking water in kitchen and living water in bathroom.
5. It is very important to purifying
edible water.
The purifying of water in washing vegetable, rice
etc is very important, or the pollutant in the water can be
easily diffused its harmful effect by heating, storage etc.
6. Integrated solution
to home water
The quality of drinking water is very important
to our health, perhaps is also the most neglected link of all
the health plans. We can produce the water that doesn’t contain
the harmful substances, at the same time, keeps certain amount
of rigidity and TDS value. We can also choose a suit of applicable
family water filter to solve the problem of drinking water and
using water in the bathroom, the filter of tap is mainly for
drinking.
Chapter
4. Water Filter
1. Usual water filter
For the moment, water filters
in the market mainly include the following categories:
Micro filtration filter:
Such as granule activated carton filter, PP
cotton filter, ceramic filter, KDF filter, quartz filter etc.
The precision of those filters is over 0.1 micron, which can’t
exclude the pollutants in the water effectively enough. The
granule activated carbon filter only can eliminate the peculiar
smell and chlorine, but it also can’t eliminate all the
poisonous chemical substances and other pollutants in the
water. The Micro filtration filter usually can’t attain
the standard of directly drinking water.
Super filtration filter:
Includes the single super-filtration film
filter and the filter compound with super-filtration film
and other medium (such as activated carbon, KDF). The precision
of the super-filtration film filter is about 0.01 micron,
can effectively exclude the silt, rust, resin, bacteria etc
harmful substances, synchronously, keep the profitable mineral
microelements. If only adopt the single super-filtration film
filter, which can’t effectively exclude the peculiar color
and smell, chlorine and heavy metal ion, it should be mixed
with other medium, such as activated carbon, KDF etc filtration
material, the effect will be better.
Reverse osmosis pure water machine:
Reverse osmosis device could remove the necessary
mineral substance (calcium and magnesium) and other substances
in the water, and produce highly softened water that is not
beneficial for health.
Mineralizing, magnetizing, activating and energy water filter:
Usually speculate the notion, lack real virtual
purge function. Even if they were claimed that they have the
function of purge. They usually used the filter material of
micro-filter gradation, as active carbon, ceramics filter
etc., but which can’t effectively remove the harmful pollution
in the water.
The main problem of drinking water is chlorine,
organic compounds, THM’s and heavy metal. Wherefore, the
optimal filter is the device which can effectively decrease
these main pollution and reserve the beneficial substance
for health as Calcium, magnesium etc.
2. Real client’s value
of water filter
We can ask ourselves: “Why
do we buy water filter? What is the purpose? What characters
I wish it have?” Basing on the point of consumer, the real
good water filter should have characters as following:
Good filtrating effect:
It can remove chorine, organic matters, heavy
metal, bacterium and virus etc. At the same time it keeps
the profitable mineral matter and trace elements. It has definite
rigidity and TDS value. The produced water can be drunk directly.
Large quantity every unit:
It not only can solve family drink problems,
also can meet the problems of kitchen edible purification
and other water purification. It really can keep the whole
family use healthy water.
Low purifying cost:
The quantity of filtrating water is large;
it can realize discharge dirt self-motion. So no need to replace
the filter cartridge usually, use life is long and it is low
to cost.
Can use safely:
Make sure it does not make water and blow
out, it can use on the safe side.
Install easily and maintain conveniently.
It is easy to install, and it very convenient
to replace filter cartridge. No need to take down it by experts
with special tools. You can replace it by yourself and no
need special maintenance.
3. Mistake concept
Error 1: The more grades the
filter has, the better the effect
The filtrating effect of water filter lies
on the filtrating media not lies on the grades or figures
of filter.
Error 2: More expensive water filter is better.
The frequent psychology when people are shopping,
it is you get what you pay for. In fact, as the moment market
of water filter is during the imported period. and most consumers
know little about water purifying technology. Also some producers
and dealers do the wrongful business action, so the price
in the water filter market is very disordered, which make
consumers feel very confused.
Error 3: I am buying water to drink, no need
to buy filter.
In fact, harm matters inrush body from the
approaches as following: 1/3 inrush from mouth, 2/3 are sucked
as washing and bathing. Make sure your family and yourself
are healthy; you need to purify your household water completely.
