"We estimate that the daily inhalation dose of methylsiloxanes may exceed that of other synthetic compounds, such as PFAS and micro- and nanoplastics. We therefore underscore the urgent need for the evaluation of these health impacts."
"The findings also suggest that concentrations of methylsiloxane in the atmosphere are much higher than expected. The concentrations were highest in urban areas, with 98 nanograms per cubic meter in samples taken from the large metropolitan area of São Paulo, Brazil."
Methylsiloxane, a type of silicone used in various industries, is now found in high concentrations across urban, coastal, rural, and forest areas. Previous beliefs suggested it was limited to traffic-adjacent areas. A study from Utrecht University indicates that daily inhalation doses may surpass those of other synthetic pollutants like PFAS and microplastics. The research involved air samples from the Netherlands, Lithuania, and Brazil, revealing that these pollutants are pervasive, with urban areas showing the highest concentrations, particularly in São Paulo.
