๐Ÿงช Chapter 759 ยท Chemical Pollutants

Nelson Textbook of Pediatrics 22nd Edition | Chemical pollutants: synthetic chemicals (>85,000), endocrine disruptors (phthalates, BPA, PFAS), air pollutants (PM2.5, ozone), pesticides (organophosphates, neonicotinoids), fracking hazards, lead, mercury, PCBs, PBDEs. Children are uniquely vulnerable: higher exposure per kg, immature metabolism, developmental windows. Environmental history taking (Table 759.3).

๐Ÿ”‘ Key Principles โ€” Chapter 759
โ€ข Children are uniquely vulnerable due to higher exposure per kg, immature metabolism, developmental windows, and longer lifespan.
โ€ข Environmental history (Table 759.3): Age, home age (lead paint), water source, parental occupation, hobbies, location (industry, fracking), pica, tobacco smoke.
โ€ข Major pollutants: Lead (neurotoxin, IQ loss), PFAS (forever chemicals, vaccine response), phthalates/BPA (endocrine disruptors), air pollution (asthma, lung growth).
โ€ข Prevention: Chemical safety legislation (REACH, Frank R. Lautenberg Act). Organic produce reduces pesticide exposure. Test well water.
