Their exceptional chemical stability allows environmental persistence exceeding two decades, leading to progressive bioaccumulation through food webs and preferential storage in lipid-rich tissues ( Human exposure to these compounds occurs through multiple pathwaysingestion, inhalation, and dermal absorptionwith subsequent accumulation in adipose tissue, hepatic systems, and critically, reproductive organs ( 1.2 Key research challenges Despite substantial advances in understanding individual EED toxicity profiles, several fundamental knowledge gaps continue to impede comprehensive risk assessment: Complex Mixture Effects Remain Poorly Understood While toxicological studies have extensively characterized individual EED effects, real-world human exposure invariably involves simultaneous contact with multiple compounds

Recall from Equation 16.23 that the p K b of a weak base and the p K a of its conjugate acid are related: p K a + p K b = p K w

Because it works locally on the scalp, topical finasteride keeps systemic exposure very low, reducing the chance of side effects while maintaining effectiveness
