Aspidia

Interesting work. At ASPIDIA we develop on-site PFAS destruction: TriClean (cavitation + oxidation) and DEHA (engineered enzymes) mineralize them into harmless byproducts with low energy and no secondary waste. Destruction at source is the sustainable way.

Yes, PFAS contamination is likely underestimated—not only in drinking water, but especially in wastewater, the sea and the environment, from which it can migrate from one continent to another.

Actual PFAS levels in U.S. drinking water may be twice the reported figures, understating the long-term risk. We need low-cost, effective mineralization methods that fully destroy these compounds instead of just moving them around—otherwise the burden keeps growing.

467 pregnant women, Odense Child Cohort: each doubling of PFOS, PFOA or PFNA in early pregnancy was associated with about 5-6% lower 24h urinary aldosterone later on. Association, not cause; no link with plasma levels. Source: doi 10.1016/j.envres.2026.125781 #PFAS

Project Viva: PFAS at age 8 were associated with few DNA methylation changes, and only one was seen again in adolescence. Epigenetic age effect: 0.02 years. Modest findings deserve visibility too. Source: doi 10.1016/j.envres.2026.125759 #PFAS

Network toxicology links PFOA to male reproductive disorders via 10 shared genes (AR, ESR1, NOS, BCL2...). Source: doi 10.1186/s12610-026-00328-y Computer predictions plus preliminary cell tests, typically at high doses: relevance to humans unknown.

Bacillus isolates from textile wastewater produce a laccase that decolorizes black, yellow and red dyes at pH 7 and 42 °C. Bacterial enzymes can break down industrial pollutants: a basis for industrial remediation. Source: doi 10.1371/journal.pone.0354516

Full-scale composting plant: 33 PFAS at 4.1 μg/kg in feedstock, 4.0 in finished compost. Composting does not remove PFAS, and oxidizable precursors hide more. Leachate and pit sediments carry them too. Source: doi 10.1016/j.chemosphere.2026.145108

In 1,000+ healthy men, PFAS in seminal plasma (not blood) were associated with longer sperm telomeres; no link with mitochondrial DNA copy number. Association, not cause: the biology is open. Source: doi 10.1016/j.jhazmat.2026.143663

River biofilm exposed to 100 ng/L for two months concentrated PFOS about 15,000-fold and 6:2 FTS about 850-fold. Source: doi 10.1016/j.ecoenv.2026.120850 Accumulation is not removal: it moves PFAS into the base of the food web.

117 Australian tap water samples, 75 PFAS targeted, 65 detected. Levels low (median 1.4 ng/L), but the 6 PFAS regulated by U.S. EPA were a median 11% of the total. A short monitoring list misses most of the mass. Source: doi 10.1016/j.envpol.2026.129260

Fruit flies carry PFAS out of landfills: an estimated 1.49 kg/year across China, rising with warming, especially GenX and 6:2 FTS. Source: doi 10.1016/j.envpol.2026.129264 A landfill is an active PFAS source. Leachate is the bigger exit: destroy PFAS there.

ECHA's committee recommends classifying TFA as reprotoxic and very persistent in water. Before new rules: can we destroy it at scale? At what cost? With what benefit? ECHA could start by funding TFA destruction research. Destroying PFAS is our work at ASPIDIA. #PFAS #TFA

In simulated paddy soil, bacteria degraded the bioplastic PHBH almost completely at 35 °C, turning it into methane and CO2. Source: doi 10.1264/jsme2.ME26036 Microbes can destroy a polymer: the principle behind industrial bioremediation. PFAS are the harder target.

To be fair, this is true for almost any company. Most businesses become remarkably profitable once someone else agrees to pay their major costs. The difficult part has always been the bit in between: revenue minus expenses.
