Pharma 71: Environmental Toxicology - Exposure, Accumulation, Aftermath

This episode explores environmental toxicology as the pharmacology of unintended dosing. Unlike therapeutic drugs, toxins enter the body without consent, instruction, or clear timing-through air, water, food, and work. We examine carcinogens and heavy metals to understand dose–response relationships, bioaccumulation, latency, and organ selectivity, and why harm often appears long after exposure has ceased. The clinical stance is forensic and preventive: recognising patterns, interrupting exposure, and supporting recovery where possible.Key takeaways to orient thinking:* Exposure pathways: inhalation, ingestion, dermal contact-and why route matters.* Dose and time: acute toxicity vs chronic accumulation and delayed disease.* Organ tropism: why certain toxins target liver, kidney, bone, or nervous system.* Heavy metals: lead, mercury, arsenic-mechanisms and chelation limits.* Systems response: occupational history, public health action, and prevention as therapy.
