Burned to Earth – The Poetry of Science

-


Between the ash-fall
and sun-scars,
a bitter hint stays –
scattered metals
threaded into earth’s pores and skin,
silent poisons
etched by unseen palms.
Wind carries remnants
of what settled
when flames faltered,
carving a path
by way of soil’s pores and skin,
leaching into root-threads
that thirst with out figuring out.
Within the hollowed floor,
the residue waits –
unspooling
it finds its means
into bone-water,
unseen,
but heavy.

A large airtanker plane drops a vivid red cloud of fire retardant over a smoky, burning hillside in Chelan, Washington. The wildfire, part of the Chelan Complex fire, creeps dangerously close to residential homes nestled at the base of the hills. Thick smoke drifts across the landscape, partially obscuring the scorched terrain. The scene captures the intense effort to protect the community from the advancing flames.

This analysis examined steel concentrations in a number of fireplace suppression merchandise, together with these authorized by the U.S. Forest Service and others out there for shopper use. It discovered that long-term fireplace retardants contained poisonous metals, akin to lead, arsenic, and cadmium, at ranges as much as 2,880 occasions larger than what’s allowed in ingesting water. These concentrations might additionally exceed security thresholds for aquatic life, posing a danger to native ecosystems when launched into the atmosphere. In distinction, water enhancers and Class A foams contained decrease steel concentrations. The examine estimated that between 2009 and 2021, roughly 380,000 kilograms of poisonous metals had been launched into the atmosphere by way of fireplace retardant use within the U.S. These findings spotlight the necessity for larger transparency in regards to the contents of fireside suppression merchandise and a reassessment of their environmental affect.
