Brain Waves D (click "back" on your browser to return to home page) Science Gone Wrong How often does science find solutions for problems and then find
that the solution causes another problem. A lot of money is spent in the World to test drugs
to make sure they are safe. Even something as simple as getting clean drinking water may have
a dangerous effects which are not foreseen. In Bangladesh many years ago the United
Nations wanted to help the people of Bangladesh have clean drinking water. They had
been drinking water from rivers and small pools after the rain. That water had
many dangerous bacteria and caused health problems. The solution was to put
a simple tube well (pipe) into the ground down to the water level
and then pump out clear water. Over 50,000 tube wells were installed. And the
people had water to drink that did not have bacteria. Wonderful, now the people
have clear water. The problem is that some arsenic, which occurs naturally in soil
in central, southwestern and northeastern Bangladesh, is always present in ground water.
The threat of arsenic contamination was first detected in 1996. Water polluted
with arsenic can cause early symptoms which include the development of dark
spots on the skin. Constant exposure can also affect internal organs and in
the most severe cases can lead to cancers and skin diseases. When they tested
the water, they found that in 29 percent of the 51,000 tube wells tested it
was found to be contaminated with arsenic. United Nations Children's Fund (UNICEF)
said it was helping Bangladesh in providing a screening program to supply arsenic-free
drinking water safe drinking water to 24 million people exposed to arsenic contamination.
UNICEF is helping with tests and looking for other water sources. The agency
also supports the training of 1,600 medical officers and 5,000 field health
workers. UNICEF is also assisting the government in creating awareness of how
to avoid using polluted water. Many Bangladeshis still use water containing
arsenic even though they know its dangerous effects on health because they can
not find other easy ways to get water. This is why many people now do not trust scientists that have
ideas the scientists think will make life better. We need to be careful that we do not
destroy the environment where we live. Simple things like where we put trash may affect
the earth in the future. Sometimes people do things because it costs less, but
in the future it may cost a lot to repair the damage to the earth or cause serious
health problems in the future. Many companies try to build equipment that is safe but buyers do not
use the equipment properly. 7 million infant swings have been recalled after six children
were strangled while using them. The swings were made before November 1997,
and the company wants to replace parts that were either not used or were lost.
The six deaths occurred when parts were missing or were not used properly and
infants slid down the swings' seats and became tangled in the restraints. In
five of the deaths, the swings were secondhand, and had missing parts. The swings
are battery-powered or windup and sold for between $70 and $120 each. Parents
were urged to stop using the swings until they get safety information by contacting
the company. Trouble In Toyland: Who designers make toys to interest children
some times they make them so that the toys may be dangerous. Here are some examples of
hazardous toys. These toys have small parts which young children could put in
their mouth and choke. 1. Babe The Pig And Friends Bedtime Babe, 2. Farm, 3.
Free Wheeling ConstructTeam, 4. Mini Construction Play Set, 5. Movie Star Gold
Jewelry, 6. Mini Fruits and Vegetables Bucket. These toys have poison in the
plastic they are made of: (most of them are teething rings) 1. Baby Looney Tunes
Cooling Ring Teether, 2. Cool Ring Teether, 3. Funny Face Teether Rattle/Disney
Babies Mickey Collection, 3. SofSport Teether, 4. Sports Fan Water Teether,
5. Toteables Glow In The Dark Fashion Accessories. These toys are examples. Other toys may also be hazardous. Even toys
that pass all government tests may be hazardous. We need to be careful and think about
the toys and equipment that we use. Chernobyl Kills And Cripples 14 Years After BlastBy
Olena Horodetska KIEV (Reuters) Fourteen years after the world's worst nuclear disaster, Chernobyl
power plant is still reaping a harvest of deaths, Ukraine's Health Ministry said. Some 3.5
million people, over a third of them children, have suffered illness as a result
of the contamination and the incidence of some cancers is 10 times the national
average. ``The health of people affected by the Chernobyl accident is getting
worse and worse every year,'' Deputy Health Minister Olha Bobyleva told a news
conference. ``We are very disturbed by these data.'' Chernobyl's number four
reactor exploded in the early hours of April 26, 1986, spreading a poisonous
radioactive cloud over much of Ukraine, Russia, Belarus and parts of Western
Europe. Soviet officials, who initially tried to hush up the tragedy, acknowledged
in the end that the accident had killed 31 people and affected thousands more. But the real scale of the catastrophe, which displaced hundreds of
thousands of people and turned bustling villages and towns into ghost communities populated
only by stray dogs and crows, has turned out to be far greater than once thought.
Official data show that the health of some 3.5 million people, including 1.26
million children, was affected in this impoverished nation of 50 million. Children
and also emergency workers sent in to clean up the contaminated areas are among
the worst affected. The death rate among those living in contaminated areas
is 18.28 percent per 1,000, compared to a national average of 14.8 percent.
Bobyleva said high radiation had led to an outbreak of diseases of the nervous,
blood and respiratory systems. She said the number of these diseases among children affected by the
accident was 17 percent higher than the national average. The rate of thyroid cancer
remains 10 times higher than normal among Ukrainian children. The ministry reported
1,400 cases of thyroid cancer between 1986 and 2000, while no cases were registered
between 1981 and 1985. Bobyleva said the ministry was particularly worried by
an increase in deaths of emergency workers, popularly called ''liquidators,''
most of whom are still under 50. The death rate in the group is double the national
average. She said the consumption of radioactive food produced in the country's
most contaminated northern and central regions of Kiev, Chernihiv, Zhytomyr,
Cherkassy and Rivne posed another danger for public health. A lack of cash and other economic problems have further complicated
the situation. Cash-strapped Ukraine has spent $1.4 billion to date to fight the consequences
of the accident. Ukraine has promised it will close Chernobyl's last operational
reactor by the end of this year. PUZZLE What is in the middle of every month, but never in March, April, or May, always
