πŸ”‘ Key Principles β€” Chapter 757
β€’ Children are uniquely vulnerable: Higher exposure per kg, immature metabolism, developing organs, longer lifespan for chronic disease.
β€’ Environmental history (Table 759.3): Age, location, symptoms (asthma, neurodevelopmental), home age (lead), water source, parental occupation, hobbies.
β€’ Climate change threats: Heat illness, air pollution (ozone/PM2.5), wildfires, flooding (mold β†’ Stachybotrys), vector-borne diseases.
β€’ Key toxicants: Lead (neurotoxin, pica), mercury (fish, Minamata), arsenic (well water, rice), PFAS (forever chemicals), phthalates/BPA (endocrine disruptors).
