Maruko is gifted a vinyl bento box by her father that she loves and brings to school daily. One morning she wakes up late and forgets her bento box at the store during her rush to buy breakfast. She realizes her mistake later but cannot find the box. Her classmate Kenichi informs her that vinyl bento boxes contain harmful phthalates. Their teacher explains that phthalates are endocrine disruptors linked to health issues. Though upset to lose her box, Maruko is relieved to learn her favorite item posed risks. She resolves to get a non-phthalate bento box.
2. Maruko is a little girl
live in a small
hometown. She is
surrounded by her
loving friends and
family.
One day, her dad gave
her a present. It was a
vinyl bento(lunch) box!
3. Maruko Chan was so
happy! The bento box
was special and popular.
She brought the bento
box to school.
At school, she showed
off her bento box that
she owned. Everyone
was jealous of her.
4. Maruko told her best
friend ,Tamayi, that it
was the birthday
present she received.
The bento box had
become her most
favourite thing ever!
Tamayi knows that
Maruko is a reckless
person. So, as a good
friend, she adviced
Maruko to take a good
care of the bento box.
5. But for Maruko,
everything will be fine.
I am not that clumsy,
thinks Maruko
One fine day, Maruko
woke up late for school.
She didnt move even
when her mom wakes
her up.
6. Maruko was awake but
still sleepy. Her mom
told her to go to the
store to buy her own
breakfast as she
already late.
When she arrived at
school, she noticed
something different.
Ok
It seems like she has
forget something. But
she couldnt remember
what it is.
7. Maybe it just my
feelings. Hm, I
shouldnt have wake up
late today, Maruko try
to convince herself.
She feels
uncomfortable for the
whole day. When school
over, she go straight
back to her house.
8. Oh Maruko. I have
prepared your lunch. By
the way, where are your
bento box? Did you
brought it to the school
today? her mom ask.
That was the moment
that she knew that
shes totally in trouble.
She left the bento box
at the shop!!!!
9. Mom! My fav Bento
box! I think I
accidentally left it at
the shop in the
morning
Dont cry Maruko. Try
to find it first. Maybe
it still there. Who
knows right?
10. Maruko was determined
to find her bento box.
She will do anything to
get her favourite vinyl
bento box back!
She go to the shop to
see if her bento box is
still there. Sadly, she
couldnt find it.
She still not giving up.
She decided to try
again tomorrow.
11. Maruko tried to make a
poster about her lost
bento box. She thought
that if she lucky
enough, maybe she will
get the bento box
back.
Suddenly, her
classmate Kenichi says,
Maruko, I think it is
better for you to let
go. It is great that the
bento box is missing.
Believe me
12. Maruko is so shock to
hear that from Kenichi.
But why? she asked.
I have google about the
vinyl bento box, and it
actually contain high
amount of phthalates! It
is dangerous and I think
its better for Teacher
Togawa to explain this to
us.
13. Ok students. Since
this turn into a fuss,
let me explain to you
what actually Phthalate
is. Before that, Im
sorry for you Maruko.
..I have prepare
softcopy on this topic
for you guys. Do take a
look. This is important
for you and your
family.
16. What is Phthalate?
A type of plasticizer that is most
commonly used in the world.
Known technically as dialkyl or alkyl aryl
esters of 1,2-benzenedicarboxylic acid.
It provides flexibility increase the
durability, and transparency of a material.
Can be found in toys, automobiles, food
packaging, cosmetics, cleaning medical
devices, and household furnishings.
Phthalates have been identified as
reproductive and developmental toxicants,
and cause major health concerns.
18. Health & Environmental
Concerns
Unexpectedly, phthalates that are being
used to produce many products in this
world are categorized as the endocrine
disrupting chemicals (EDCs).
Phthalates are known as xenoestrogens
which is a type of xenohormone (endocrine
distruptor), that acts as oestrogens once it
is being absorbed in the body.
These EDCs will interrupt with the normal
hormonal function and metabolism that
cause many side effects.
20. Health & Environmental
Concerns
Phthalates might likewise posture
dangers for amphibian and terrestrial
ecosystems particularly in the region of
phthalate processing industries.
Some phthalates are bioaccumulative and
have been detected in aquatic organisms.
For example, BBP has been shown to be
poisonous to aquatic organisms and may
cause long-term adverse effects in aquatic
environments.
Studies suggest BBP may have endocrine
disrupting effects in fish. Birds and
mammals may suffer impacts from food
chain exposures.
23. What is Dioctyl Terephthalate?
Dioctyl terephthalate (also known as
DOTP or DEHT) is a non-phthalate
plasticiser. It is really known as the
excellent toxicological profile. It is also
has a long life-span as phthalate.
As phthalate is widely being used in PVC,
scientists had managed to develop DOTP
to replace the usage of phthalate to
softening the PVC plastics.
DOTP identified to have the same
chemical properties with phthalates
(DEHP and DINP), which are used in PVC
but without any negative regulatory
pressure PVC plasticizer due to its
excellent toxicological profile.
27. Conclusion?
The usage of phthalates plasticizers
should be banned and supplant with non-
phthalates plasticizers. In long term,
utilizing phthalates can be quite
dangerous and can be an alarming issue to
the society such as health concern and
environment. There are numerous
different materials that can be used to
minimized the usage of phthalates . To
conclude say 'no to the phthalates'.
Prevention is better than cure.
28. For dearest Maruko,
Get a non-toxic lunch box. Like cloth lunch
box and stainless steel lunch box.
30. WOW, I didnt know
my favourite thing can
become something so
dangerous, think
Maruko.
Anyway, Maruko felt
relieved. Theres
actually silver lining
behind all of these
situations.
31. Tamayi told Maruko
that someday, she will
get her new bento box.
Non-phthalates and
safe one.
THE END
Theyre happy that they
learn something
important and useful.
