This study examined how a range of forever chemicals enter the air when aerosolised from contaminated solutions, with & without bacteria-seed (bioaerosol). The way these chemicals were aerosolised was key to their behaviour in air and their inhalation relevance, as they mainly formed tiny particles that reach deep in the lungs. The bacterium had little effect, suggesting the chemicals are unlikely to be removed by bioaerosol, enabling long range transport and contributing to inhalation exposure.
