Matching Solution:

1. Sewage water
- Match: Image 8 (A container leaking liquid into a river).
- Explanation: Sewage water typically refers to wastewater from households and industries that can leak or be improperly disposed of into water bodies.

2. Factory waste
- Match: Image 4 (A factory emitting smoke).
- Explanation: Factories often discharge industrial waste, including pollutants, into water bodies.

3. Chemical substances
- Match: Image 9 (Bottles and containers of chemicals).
- Explanation: Chemical substances are often stored in bottles and containers, and their improper disposal can lead to water pollution.

4. Pesticides
- Match: Image 1 (A person spraying a field).
- Explanation: Pesticides are chemicals used in agriculture to control pests, and they can runoff into water bodies when sprayed on fields.

5. Radioactive waste
- Match: Image 10 (Radioactive waste barrels).
- Explanation: Radioactive waste is typically stored in specialized containers and can cause severe pollution if not handled properly.

6. Plastic
- Match: Image 6 (A plastic bottle washed up on the shore).
- Explanation: Plastic waste, such as bottles, is a major contributor to water pollution, especially in oceans and rivers.

7. Trash
- Match: Image 3 (A large pile of garbage).
- Explanation: Trash includes various types of solid waste, which can end up in water bodies and cause pollution.

8. Oil spills
- Match: Image 2 (An oil spill in the ocean).
- Explanation: Oil spills are a direct result of accidents involving ships or pipelines, leading to visible pollution in water bodies.

9. Fertilizers
- Match: Image 5 (A farmer applying fertilizer to crops).
- Explanation: Fertilizers are applied to crops but can runoff into water bodies during rain, causing pollution.

10. Algae
- Match: Image 7 (A body of water covered in green algae).
- Explanation: Algae blooms occur due to excess nutrients (e.g., from fertilizers) in water, leading to the growth of excessive algae.
