The document discusses microplastics as a dangerous pollutant. It defines microplastics as plastic pieces smaller than 4.8-5 mm. Microplastics can be found in soil, sediments, and water and can harm the environment and organisms. The document also discusses the types of microplastics, their properties, and the impacts caused by microplastics such as environmental contamination and threats to health.

PEMBAHASAN

6. WHAT IS
MICROPLASTIC
?
Mikroplastik adalah potongan
plastik yang berukuran lebih
kecil dari 4,8-5 mm. menurut
Lusher dan Peter, plastik adalah
bahan yang dibentuk pada suhu
dan tekanan tertentu.

7. MIKROPLASTIK
DAPAT DITEMUKAN
DIMANA?

8. JENIS-JENIS
MIKROPLASTIK
Mikroplastik primer adalah hasil produksi plastik yang dibuat
dalam bentuk mikro,
1.
2. Mikroplastik sekunder adalah pecahan, bagian, atau hasil
fragmentasi dari plastik yang lebih besar.
Persamaan dari microplastik primer maupun sekunder
adalah dapat bertahan di lingkungan dalam waktu yang
lama.

9. Sifat Mikroplastik
Mikroplastik sangat tahan terhadap biodegradasi dan dapat
bertahan di lingkungan selama ratusan tahun dnegan potensi
menyebabkan kerusakan ekologi dan biologis.

PENUTUP

12. Kesimpulan
Mikroplastik adalah potongan-potongan plastik yang
dihasilkan oleh proses pemecahan dan penyusutan
ukuran plastik yang disebabkan oleh beberapa faktor.
Mikroplastik dapat masuk ke dalam sedimen tanah
mauoun air ang dapat mencemari lingkungan dan dapat
memebrikan dampatk buruk pada hewan dan manusia
sehingga dapat menyebabkan keracunan. Perlu upaya-
upaya dan kesadaran banyak pihak akan bahayanya

13. STATES OF
WATER

14. This occurs when water is subject to a
temperature of less than 0ºC and it
freezes. The phenomenon gets the
name of solidification and it occurs
when all the molecules going to make
up water are united. In this state, we
found water in glaciers or in
mountainous snowy areas.
SOLID
STATE

15. This is the most predominant form of
water on the Earth’s surface. It is found
in this form in rivers, lakes, seas,
oceans… Its passage from a solid to a
liquid state is given the name of
melting; this state, in which the majority
of molecules — but not all of them —
are joined, occurs between 0º and 100º.
LIQUID
STATE

16. When water is subject to a certain
temperature, evaporation occurs.
Water from the oceans, rivers, lakes
or other aquatic sources evaporates
and condenses into the atmosphere.
In this way, the clouds appear,
comprising an accumulation of water
particles. In this case, the molecules
are completely released.
GASEOUS
STATE

17. PROPERTIES OF
WATER

18. PHYSICAL
PROPERTIES
- Its density is 1 g/cm³, in other words, 1 cubic
centimetre of liquid water weighs 1 gram. By
contrast, when it is in solid state, its density is less,
that’s why ice floats on water.
- Its freezing point is 0 ºC, whilst its boiling point is
100 ºC at sea level.
- The water on the planet is in constant flux and
always in motion.

19. PHYSICAL
PROPERTIES
- It has the capacity to absorb a lot of heat before its
temperature rises. Thanks to this property, it helps to
regulate the change in air temperature in the different
seasons of the year.
- It has very high surface tension which is why it is
sticky and elastic. And it is this characteristic of water
that allows some insects like spiders to walk on it.

20. CHEMICAL
PROPERTIES
- Its chemical formula is H²O: one oxygen atom bound to two hydrogen
atoms.
- The water molecule has a positive electrical charge on one side and
negative on the other, a property which causes its molecules to bind.
- It contains very valuable minerals and nutrients.
- Pure water has a neutral pH of 7: neither acidic nor basic.
- It reacts with acidic oxides, basic oxides and metal.

21. WE CAN FIND
WATER IN…
Rivers, lakes, oceans, glaciers and
even in our body.

22. LOOKING
AFTER WATER
03

23. 5 TIPS FOR LOOKING
AFTER WATER
When you're having a
bath, collect cold water
whilst the hot water is
coming out. You can
use it to clean the house
or car, water the plants
or give it to your pet.
Don’t take too long
having a shower. Have a
quick shower and turn
off the tap whilst you're
soaping up or washing
your hair with shampoo.
Use biodegradable
cleaning products for
the general cleaning of
the house, the dishes
and dirty clothes. In this
way the waste water
won't be contaminated.
DON’T WASTE COLD
WATER
MAKE THE MOST OF
YOUR DAILY SHOWER
USE ECOLOGICAL
PRODUCTS

24. 5 TIPS FOR LOOKING
AFTER WATER
When you brush your
teeth, turn off the tap. In
this way, a family of 5
can save up to 40 litres
of water per day.
Use any water that got
dirty in the washing
machine to clean other
areas of the house such
as corridors and yards.
DON’T LEAVE THE TAP
RUNNING
MAKE SURE TO REUSE
WATER

25. WATER POLLUTION
Water pollution takes place when natural bodies of
water (lakes, rivers, seas etc.) have the presence of
various types of chemical substances unrelated with
their original composition, which modify their
properties, making it unhygienic, harmful to life and
thus useless for fishing, farming, recreation and
human consumption.

26. MAIN
CONTAMINANTS
The product of urban consumption
(sewage), from industrial processes or
from other daily human uses.
WASTE WATER
The chemicals used in the farming industry, to treat soils or for other
occasional uses are frequently washed by the rain and run into the
sea or underground waters.
CHEMICALS AND AGROTOXIC PRODUCTS
Such as waste materials, metals,
plastics, glass, objects that fall from
boats etc.
REFUSE AND SOLID WASTE

27. MAIN
CONTAMINANTS
Such as volcanic ash,
sediments and particles
from the soil or
constructions, such as dust,
lime, etc.
SEDIMENTS AND
MINERALS
Extremely toxic elements
which are stored in lead
containers and are thrown
into the ocean as there is
nowhere to put them.
RADIOACTIVE
MATERIALS
