Antarctica’s tourism faces high levels of pollution
(MENAFN) Once regarded as one of Earth’s most untouched environments, Antarctica is facing increasing environmental strain as human presence grows. Scientists caution that surging tourism and expanding research operations are contributing to higher levels of pollution across the continent.
A recent study revealed that in regions where human activity is concentrated, the amount of fine particles containing heavy metals has risen to levels ten times greater than those measured four decades ago.
This trend coincides with a rapid increase in visitors—annual tourist arrivals have climbed from about 20,000 to 120,000 over the past twenty years, according to industry data.
To assess the impact, an international team of researchers conducted a four-year survey, covering roughly 2,000 kilometers (1,242 miles) of Antarctic terrain to measure levels of contamination.
“We identify distinct spatial patterns shaped by crustal, marine, biogenic and anthropogenic sources. Notably, we detect heavy metal imprints in the snow chemistry of the northern Antarctic Peninsula, where major research stations are concentrated and marine tourism traffic is most intense," the researchers said.
They further noted: "Our findings shed light on the extent of the impacts from energy-intensive local activities in Antarctica, underscoring the need for enhanced environmental monitoring and sustainable management strategies in this fragile region.”
