A majority of people in Medawachchiya, Padaviya and Kebithigollewa
areas in Anuradhapura district are reluctant to drink water in fear of
contracting renal ailments in the region. They are also afraid of using
aluminium utensils for domestic purposes.
It is the duty of the intellectuals to clear their doubts and
suspicious and make them continue their normal lifestyles, said Dr. (Mrs)
Janitha A. Liyanage of the Department of Chemistry, University of
Kelaniya.
She was delivering the keynote address at the residential workshop on
"Safe use of Pesticides and Aluminium Utensils" held at the "Nature
Resort" Anuradhapura recently.
The two day residential workshop was sponsored by "World Vision
Lanka" and organised by the Environmental Committee of the Sri Lanka
Association for the Advancement of Science (SLAAS).
A team of 30 persons consisting of senior science students and a
group of science and Agriculture teachers in Galenbindunuwewa
Educational Zone participated at the workshop. The workshop is the first
programme of a series of workshops to be conducted in this year on "Safe
Use of Pesticides and Aluminium Utensils," for schoolchildren in order
to enhance the knowledge on the subject.
"The Sri Lanka Association for the Advancement of Science has decided
to give priority to the North Central Province where pesticides are used
extensively as well as aluminium utensils.
This workshop will undoubtedly develop the communicating skills and
knowledge of the students to enable them to pass the message to the
elders in their villages including the parents regarding the aluminium
appliances and agro chemicals," Dr. (Mrs) Liyanage explained.
"Several studies conducted by agricultural and other organisations
have found that a high percentage of farmers in the country use
pesticides exceeding the required dose and concentration. On the other
hand considerable numbers of deaths are also reported due to pesticide
poisoning yearly. In addition people are used to using aluminium
utensils for their household purposes.
Specially in the NCP coincidently and simultaneously the number of
chronic kidney failures and numerous kidney ailments are on the rapid
increase," Dr. Liyanage pointed out.
The Chemist Janitha Liyanage who is a PhD holder of the Cardiff
University in United Kingdom in Chemistry and also the Chairperson of
the Environment Committee of Sri Lanka Association for the Advancement
of Science, said that the exceptional quality in Aluminium was that both
acidic and basic elements dissolved with Aluminium in the same manner.
The Aluminium made a complex when mixed with water which couldn't go
through the body cells and as a consequence its diffusion and
absorption, in the human body was low she explained.
Also the Aluminium oxide layer which protects the underlying
Aluminium in coming into contact with any more oxygen and when cooking
in these utensils the protective layer gets dissolved or erased and
absorbed into the body.
In the process when the Aluminium percentage has exceeded a dose of
grams o.1 which is the maximum of Aluminium, a human body, weighing 70
kilograms should have in it, the surplus metal is known to accumulate in
intracellular sites of brain tissues and in the central nervous system.
Such aluminium could induce loss of memory, having impaired intellect,
Dr. Liyanage stressed.
"This situation influences the filtering mechanism in the kidneys and
in the process aluminium would deposit in the kidneys, along with other
waste which leads to the kidney ailments effecting the urinary system.
In the circumstances aluminium could enter the body even from
drinking water from a Aluminium water pot.
In the context it is more advisable to reduce the usage of Aluminium
utensils as much as possible as such a practice immensely helps for a
healthy life," she emphasised further.
She pointed out that for avoiding health hazards caused by overdose
of Aluminium in the body the people should take to the utilisation of
clay kitchen utensils, cooking vessels, coconut spoons and traditional
appliances such as 'Pittu bambuwa' made out of bamboo, wooden string
hoppers squeezer etc instead of Aluminium accessories.
There should be a adequate awareness among the people regarding the
importance of this type of a lifestyle to get rid of formidable
ailments, such as renal diseases anamia, digestive problems, liver
failures etc.
