Takeaways

• 😀 Pollution occurs when harmful substances reduce the quality of the environment and disturb the ecosystem balance.
• 😀 Pollutants are substances that contaminate the environment, causing various types of pollution.
• 😀 Keli, Ijar, and Cita are investigating environmental pollution in their respective cities for a national science competition.
• 😀 Keli, who lives near industrial areas, found water pollution in local rivers, caused by untreated textile factory waste and household waste.
• 😀 The consequences of water pollution in Keli's area include dead aquatic plants and fish, unsanitary water, and the spread of diseases.
• 😀 Solutions for water pollution include installing wastewater treatment plants and preventing waste disposal in rivers.
• 😀 Ijar, living near a mining area, identified soil pollution caused by waste disposal and mining by-products containing heavy metals.
• 😀 Soil pollution results in dry, infertile land, hazardous gas emissions, and health issues for those exposed to the contaminants.
• 😀 Remediation, which involves cleaning polluted soil using microorganisms like fungi and bacteria, is an effective solution for soil pollution.
• 😀 Cita, who lives in a densely populated urban area, observed air pollution caused by vehicle emissions, trash burning, and smoking.

Q & A

What is environmental pollution?

Environmental pollution refers to the introduction of substances or agents that decrease the quality of the environment and disrupt the balance of ecosystems.

What is a pollutant?

A pollutant is a substance that causes pollution in the environment.

What type of pollution did Keli observe in her area?

Keli observed water pollution in the river near her home, where the water had turned black and smelled bad, making it unfit for drinking or washing.

What were the causes of water pollution near Keli's home?

The water pollution was caused by untreated textile factory waste containing dye residues and heavy metals, as well as household waste like food scraps, vegetables, and plastic.

How can water pollution be addressed according to Keli's report?

Water pollution can be addressed by setting up a wastewater treatment plant (IPAL) to process factory waste, and by recycling waste or reducing daily waste production to prevent it from being dumped into rivers.

What type of pollution did Ijar find in his area?

Ijar discovered soil pollution in his area, where the soil was dry, mixed with trash, and sometimes emitted a foul odor.

What caused the soil pollution in Ijar's area?

Soil pollution in Ijar's area was caused by improper waste disposal, particularly plastic and paper waste, as well as mining waste containing heavy metals.

What is remediation, and how can it help with soil pollution?

Remediation is the process of cleaning the surface of the soil from pollutants. It can be assisted by microorganisms like fungi and bacteria that break down contaminants into safer substances.

What type of pollution did Cita notice in her urban area?

Cita noticed air pollution in her area, caused by smoke from various sources, such as burning waste, cigarette smoke, and vehicle emissions.

How can air pollution be prevented according to Cita's findings?

Air pollution can be prevented by planting trees or engaging in reforestation efforts, which help absorb carbon dioxide, and by replacing gasoline-powered vehicles with electric ones that don't produce smoke.

What was the impact of environmental pollution on Keli, Ijar, and Cita?

The pollution made Keli, Ijar, and Cita concerned about their environment, leading them to learn more about pollution types and ways to prevent and address it, with the aim of living in a cleaner and healthier environment.

What did Keli, Ijar, and Cita aspire to do after learning about pollution?

After learning about pollution, Keli, Ijar, and Cita aspired to become scientists, technicians, and activists, working towards achieving a cleaner and more beautiful Earth.

What are some examples of pollutants that can cause environmental damage in agricultural areas?

Examples of pollutants in agricultural areas include heavy metals, vehicle emissions, pesticide residues, and plastic waste.
