Transcript of AIR & WATER POLLUTION

There are 3 types:
-UVA rays: age skin cells & damage DNA
-UVB rays: damage DNA directly
-UVC rays: they don´t get through our atmosphere

The ozone layer interacts with UV radiation and converts it to heat specifically, UVA and UVB.
The Importance of Water
and how to repair it...
UV RADIATION
OZONE DEPLETION
WATER POLLUTION
Main cause:
HUMAN ACTIVITY!!!
-ODS, specifically

Chemicals that affect:
-Chlorofluorocarbons
-Carbon tetrachloride
-Hydrochlofluorocarbons
How to take care of it:
-Buy systems that don´t use HCFC
-Buy eco-friendly aerosols
-Keep your AC and refrigerator in good state
-Limit private vehicle driving
-Avoid using pesticides


-Key resource for life:
-Provides habitats and eco-systems for plants and animals
-Necessary for human health

WHAT IS OZONE?
OZONE & OZONE LAYER
WATER POLLUTION
-A gas composed of three atoms of oxygen (O3)
-There are 2 types:
-Good ozone: (stratospheric)
*Produced naturally in the upper atmosphere.
*Protects us from the UV radiation

-Bad ozone: (tropospheric)
*Created chemically with oxides of Nitrogen and volatile organic compounds.
*Harmful for people and the environment.

OZONE & WATER POLLUTION
Two types:
-Point: produced by a single source
-Non point: belongs to multiple sources

Common causes:
-Industrial waste
-Sewage
-Irresponsible mining
-Global warming
-Oil leakage
-Chemical pesticides and fertilizers


DISTRIBUTION &TREATMENT OF WATER IN PERU
TAKING CARE OF WATER
Ozone formation
UV radiation breaks down oxygen molecules
O2->2O
Each atom combines with an oxygen molecule (O2)
Water in Peru:
-1768172 hectometers of water
-Eight country in the world with most water
-Resourced with: lagoons, rivers and glaciars
Distribution:
-"Cuencas" are used
-Total in Peru: 159
-84 from the Amazonas
-13 from the Titicaca
-62 from the Pacific Ocean
How to stop water pollution and waste:
-Ensure waste does not end up in waterways
-Reduce the use of chemicals such as: solvents, paints, pesticides, etc.
-Collect your used oil
-Avoid placing paint or other chemicals down sinks
