"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, has been found in high concentrations across urban, coastal, rural, and forest sites, contrary to previous beliefs that it was limited to traffic areas. Researchers from Utrecht University conducted a study revealing that daily inhalation doses of methylsiloxanes may surpass those of other synthetic pollutants like PFAS and microplastics. The study indicates that these pollutants are pervasive, with the highest concentrations found in urban areas, particularly in São Paulo, Brazil, where levels reached 98 nanograms per cubic meter.
