CONSEJERÍA DE EDUCACIÓN C.P.R. AL-DEHECÚN WHAT IS THE WATER POLLUTION? Water is essential and very beneficial for the life in our planet.

Nevertheless, due to the human being activity, the Earth is being polluted and water has more harmful substances and it is losing quality. Water is changing from pure condition to a harmful one and this can affect all life.

WHAT CONTAMINATES MORE AND WHICH ARE THE CONSEQUENCES? People have realized that we need to stop pollution and the citizens are using more means to get healthy water, both fresh ( from rivers, lakes, underground waters and reservoirs) and the salty one (from seas and oceans). Nevertheless, there is a long way to obtain a better water quality in our planet.

The main water pollutants are: • Pathogenic microorganisms that can cause important diseases.

• Synthetic detergents and rich fertilizers in phosphates.

• Organic pesticides.

• Chemical inorganic products (nitrates, nitrites, fluorides …)

• Petroleum and his derivatives like the tar, oils and fuels.

aquatic animals. Nevertheless, the most harmful pollutant action in seas and oceans is the oil spillage, which kills an important part of the acuatic flora and fauna in these areas.

Water is used also for irrigation of the crops and animals drink it.

Crops and animals are our food and other animals; that means, they are part of our food chain. Thus, the pollution of the water concerns all our environment: cultures, animals and people.

Many people are affected more often by infections proceeding from the water in the poorest countries (virus or bacteria) and by toxic substances, as pesticides or chemical aggressive compounds that hurt the health.

SOLUTIONS TO AVOID THE WATER POLLUTION • • • •

•

Do not throw rubbish nor residues to the rivers and to the seas. Use the most nearby container for that.

Do not use the toilet as bucket of garbage. Put a wastebasket in the bath.

Do not throw the used oil from fried dishes to the drainpipe. You can deposit t it in a bottle made of plastic and to take it to one oil recycling point.

Put grids with small diameter mesh in the sink and the washer. This way, you will contribute to stop that the solid residues to continue the water way and then you can throw them at the garbage.

Uses biodegradable detergents to the clean and to wash.

Thus, the rivers, for example, are contaminated by the toxic products thrown in the sewer, industrial and detergent waste, fertilizers and pesticides that filter in the agricultural lands (fresh water from the subsoil). Then, considering all these matters, they eliminate progressively the natural vegetation and reduce the quantity of oxygen in the water, killing fish and other
