An investigation result which U.S.A. announces on the 9th finds, contains many kinds of materials such as antibiotic, sedative, sex hormone in the drinking water in 24 big cities in U.S.A., 41 million people drink such unsafe water at least at present.
Drink and damage chronically for a long time
Reveal, the density containing medicine is very small in water according to the survey report that Associated Press announces, quantity whether thousand billion between one and 1/1 billion, less than medical using medicine amount of use.
And all water works insists on saying, water that they offered is safe.
However, so much prescribed medicine appears in water, there are some non-prescribed medicine, such as antipyretic, anodyne,etc., this upsets scientists, it may cause the chronic damage to the health to drink such water for a long time.
A research recently indicated, took low dose of medicine to bear on breast cancer cell to renal cell, the blood cells of the human body of the human embryo long-timely. On condition that take low dose of medicine for a long time, breast cancer cells increase, accelerate, and the renal cells of the human embryo slowly grow.
In addition, the medicine in water remains will also do harm to wild animals and plants. For example, the male fish will be feminized etc..
The water works covers medicines up and remains information
Associated Press has carried on the 5 months -long investigation to the water quality of the whole country of U.S.A., find that contains medicines in 24 pieces of main and metropolitan drinking water.
Associated Press says, the water works almost never reveals the testing result of medicine residues in water, a large-scale water works of California also says, the public is " unable to understand similar information correctly " ,Once announce such detection data, may cause the unnecessary fear.
American federal government has not required that remain and measure the medicine in the drinking water before this, have not set up safety standard either. 62 investigated in Associated Press are main in the water works, only 28 gauge this. Producer that the medicine is residual including water works of Houston, Chicago, Miami, Baltimore, Phoenix, Boston and other places in not measuring water. Implement water works that medicine measure, a portion of them say, measure, appear one remain to two medicine only even.
Other water works claims not to examine medicines out to remain in water when polled, but after investigating independently personages measured, the water works has given oneself away. New Orleans water affair officer of department claim ink of city this examine out the medicine, but the investigation result of pursuing the scholar of blue university indicates, there are sex hormone, resist cholesterol medicines,etc. in the drinking water in New Orleans.
Drink the bottled water and does not insure
The expert says, some people living in the suburb get drinking water through well, river or small-scale water treatment factory,etc., water that they drink might not be clean either.
The scientist will usually judge the intensity that medicines are residual by content of the caffeine in water, lie in of researcher Anthony of Stroud Water Research Center of Pennsylvania and step on the bank to say generally, the caffeine in suburbanite's drinking water is taller in density. Step on bank to be general to guess, say suburb medicine of drinking water it remains to be might by storing that pond cause clean. "Water treatment factories of the sparsely populated area are all very small, will not probably manage carefully, lead to the fact that stores the pond and is polluted for a long time. "
Even drink the bottled water or use water filter for family, perhaps can not guarantee either water that you drank is safe. Some bottled water works just packs the spring, will not remain and especially deal with the medicine. Residual function that the filter of the service water has not filtered medicines too.
The groundwater meets with pollution too
The medicine remains the state of water of pollution and not merely takes place in U.S.A., find in lake, river, the Communist Party of China of reservoir of the whole world that has more than 100 kinds of medicines to remain, even if can't escape by luck either with the Swiss lake with pure and well-known water quality.
In U.S.A., the question of the water pollution is not merely limited to the surface water, the medicine is permeating through the groundwater now, and the groundwater is the source of 40% of the rivers of U.S.A.. Indicate after American scientist's underground aquifer investigation to 24 states, some buries the underground source of water of the field, animal's plant and already suffers pollution close to rubbish, have medicines such as sex hormone, antibiotic,etc. to examine in the water out.
If the medicine wanted to totally remove in water is residual, the cost is very expensive. And if use the general chlorination to deal with France, may make some medicines in water remain and have toxicity even more.
Relevant chaining
The medicines are various in style in the beautiful drinking water
The government official in Philadelphia says, contains 56 kinds of medicines, including analgesic, antiinflammatory agent in the running water of this market, lower cholesterol medicine, asthma medicine, heart disease medicine,etc.. Gather together area of water in this city, find together that 63 kinds of medicines remain.
In Southern California state, one water of water works find, have, resist the epilepsy medicine and resist the anxious medicine, this factory offers the drinking water to 1,850,000 people.
U.S.A. geology learn, find fill grams of valley ink of water works in, in handkerchief to analyze New Jersey, water contains medicines such as tranquillizers,etc., this factory offers the drinking water to 850,000 people.
Water in San Francisco contains sex hormone.
The drinking water of Tucson of Arizona State contains 3 kinds of medicines such as antibiotic.
The drinking water that Washington and surrounding area use contains 6 kinds of medicines.
Where will the medicine in water come?
People will absorb a part among them after taking medicines, but the remaining medicine is discharged outside the body through urine,etc.. The waste water will after dealing with be entered the reservoir, river and lake, later, the water will be cleaned again, entered the family through the water works. The most water treatment course will not remove medicine residues.
In addition, Americans use the increase of medicine quantity to cause pollution to aggravate too. In the past 5 years, the quantity that U.S.A. opened prescribed medicine went up by 12%, was up to 3,700 million parts, and the sales volume of non-prescribed medicine has reached 3,300 million.
