Welcome to ‘Microplastics Found In Tissues of Whales and Dolphins

Microplastics have become a part of our oceans, posing a silent yet significant threat to marine life, including whales and dolphins. This article dives into the startling presence of microplastics found in the tissues of whales and dolphins and the broader impact on human health.

The Silent Invasion

Microplastics, the tiny particles less than 5mm in size, have become significantly present in our oceans. These tiny invaders are not just floating on the surface; they are embedded deep within marine mammals, from the blubber of whales to the lungs of dolphins. Recent studies have revealed shocking findings: microplastics are not just passing through these creatures’ digestive systems but are becoming lodged in various tissues, posing potential health risks.

From Surface to Tissue

Marine mammals, including whales and dolphins, are ingesting these particles, often mistaking them for food. But the danger doesn’t stop at ingestion. Tissue samples from various marine mammals have uncovered the presence of microplastics in blubber, acoustic fat pads, lung tissue, and even the melon tissue found on their foreheads.

The Impact on Marine Life

The presence of these particles in such vital tissues is concerning. For instance, the acoustic fat pads are crucial for echolocation, a primary method marine mammals use for navigation and hunting. Moreover, the physical presence of these particles can cause internal wear and tear, damaging the tissues from within.

A Concern for Humans

The threat isn’t limited to marine life. As apex predators, humans are at risk of ingesting these particles through the seafood we consume. While the direct health implications for humans remain a topic of research, the fact that microplastics can be implanted in tissues means they might be entering our food chain in larger doses than previously thought. Recent findings have even identified microplastics in human blood samples and placentas.

The Scale of the Problem

The sheer volume of microplastics in our oceans is startling. Estimates suggest our oceans are now filled with over 170 trillion plastic particles. Marine mammals, some of our ocean’s most majestic creatures, are bearing the brunt of this pollution. For instance, a blue whale off the Pacific Coast of California might ingest up to 95 pounds of plastic waste daily.

Interesting fact: Did you know that blue plastic was the most commonly found colour of microplastic in all tissue types studied.

Taking Action

The first step in dealing with this issue is by becoming aware. By understanding the scale and implications of the microplastic problem, we can take collective action. Reducing plastic use, supporting bans on products with microbeads, securing proper disposal of plastics, and backing innovative solutions are all steps in the right direction. The health of our oceans, marine life, and ultimately ourselves depends on it.
