Clear, evidence-led explainers on where everyday microplastic and chemical exposure comes from, what the research does and does not establish, and the low-regret changes worth making. We show the sources and keep detection, association, and causation distinct. Rigor, not fear.
Where microplastic exposure comes from across breathing, drinking, and eating, what the health evidence does and doesn’t establish, and the practical, low-regret ways to reduce avoidable contact.
More guides in progress. Welden is building the same evidence-led treatment for PFAS “forever chemicals,” phthalates and BPA, and heavy metals. They’ll appear here as each is published and reconciled to the live model.
