GS Paper-3: Environment

⭐ Tar Balls

⭐ Why in News

The Ministry of Environment, Forest and Climate Change (MoEFCC) has issued

draft guidelines for the management of tar balls.

⭐ Definition & Nature

• Tar balls are small, dark, sticky lumps of weathered oil found in marine

environments.

• They form due to oil spills or natural seepage of petroleum in oceans.

⭐ Formation Process

• Originate from the weathering of crude oil in marine conditions.

• Ocean currents and waves transport them from offshore regions to coastlines.

• Undergo physical, chemical, and biological changes, forming semi-solid or solid

masses.

• Eventually wash ashore, posing environmental and health risks.

• Size varies widely—from tiny globules to large lumps.

⭐ Composition

• Contain toxic substances such as:

• Heavy metals

• Trace elements

• Persistent organic pollutants (POPs)

⭐ Environmental Impact

• Accumulate along coastal areas, harming marine ecosystems.

• Pose threats to:

• Seabirds

• Fish

• Marine animals like sea turtles (which may ingest them)

GS Paper-3: Science & Technology / Space
