Industrial chemicals and plastic debris, often originating from distant lands, are making their way into the Antarctic food chain. Persistent organic pollutants (POPs) like PCBs and DDT accumulate in the fatty tissues of marine animals, disrupting their hormonal systems and impairing their reproductive capabilities. Microplastics, tiny fragments of plastic that can easily be ingested, have been found in the stomachs of various Antarctic species, including penguins and seals. These tiny particles can clog their digestive tracts, causing malnutrition and starvation.

Heavy Metals: A Lethal Legacy

Heavy metals, such as mercury and lead, are another major concern. These metals can accumulate in the environment from mining activities, industrial processes, and atmospheric deposition. Once in the ocean, they can be taken up by marine organisms and biomagnified through the food chain, reaching toxic levels in top predators like seals and whales. Heavy metals can damage the nervous system, disrupt organ function, and even cause reproductive problems.

Climate Change: A Recipe for Amplification

Climate change is exacerbating the problem of pollution in the Antarctic. As the polar ice caps melt and the ocean warms, pollutants are becoming more mobile and accessible to marine life. Additionally, climate change can alter ocean currents, potentially transporting pollutants to new and vulnerable areas.
