Dark Oxygen
Syllabus: GS3/ S&T
In News
- The recent discovery of “dark oxygen” production in the Clarion-Clipperton Zone challenges conventional understanding of oxygen generation, which has long been tied to photosynthesis requiring sunlight.
Key Findings
- Metallic nodules found 4,000 meters beneath the Pacific Ocean’s surface generate oxygen through electrolysis.
- This process does not depend on sunlight, marking a paradigm shift in the understanding of oxygen generation.
Potential Applications
- This phenomenon could provide insights into life in extreme environments on Earth and other planets.
- Understanding “dark oxygen” production could assist in the search for extraterrestrial life by expanding the criteria for habitability.

DDT-Infused Soil
Syllabus: GS3/ Agriculture
Context
- Researchers from Sweden have discovered a method to reclaim infertile soil contaminated with DDT (Dichloro-Diphenyl-Trichloroethane) by mixing it with biochar.
About
- Biochar is an environmentally friendly material, akin to charcoal, that has the ability to bind contaminants such as DDT.
- This binding prevents the toxin from being absorbed by soil organisms, thus limiting its harmful impact.
- When mixed with soil, biochar improves soil fertility and helps mitigate the effects of pollution.
What is DDT?
- DDT (dichlorodiphenyltrichloroethane) is a chemical, first synthesized in 1874 and its insecticidal properties were discovered in 1939.
- Though initially hailed as an effective pest control tool, its long-term use has resulted in serious environmental and health concerns.
- Harmful effects: DDT tends to accumulate in the fatty tissues of both humans and animals, leading to long-term exposure. DDT is a persistent organic pollutant (POP).
- It was banned in the United States in 1972.
- Some countries, primarily in Africa, still use DDT to control malaria and other insect-borne diseases.
- Indian scenario: India continues to produce and use DDT, primarily for controlling vector-borne diseases like malaria and dengue.
- Hindustan Insecticides Limited (HIL) is the sole manufacturer of DDT in India.

Water Hyacinth
Syllabus: GS3/Species in News
Context
- Recently, a group of fishermen were said to be stranded on Kenya’s Lake Naivasha due to water hyacinth that has taken over large parts of it.
About
- Scientific Name: eichhornia crassipes
- It is native to South America and was introduced to Kenya in the 1980s as an ornamental plant.
- It is an aquatic weed common in waterbodies across South Asia, including India.
- It was introduced to India during the British colonial rule as an ornamental aquatic plant.
- It is considered the most invasive aquatic plant species in the world.

- Concerns:

- Disrupting Ecosystems: It reduces oxygen levels in water, harms aquatic life, and hinders sunlight from reaching underwater plants.
- Economic Impact: The clogging can affect fishing, water quality, and recreational activities, leading to significant financial losses.
- Efforts to control water hyacinth include physical removal, biological control (using insects or other species), and chemical treatments.
