Córdoba Province is presented as a place where arsenic contamination of drinking water has made chronic poisoning and arsenical skin cancers endemic. The example extends the book’s concern beyond acute pesticide incidents: contamination rooted in local geology can expose people over time, while long-term use of arsenical insecticides could create comparable conditions elsewhere.

Contaminated drinking water

The account attributes the problem in Córdoba Province to drinking water derived from rock formations containing arsenic. Because the water is a continuing source of exposure, the contamination is linked not just to poisoning but to chronic illness accompanied by skin cancers. The passage identifies the source and consequences without specifying the number of people affected or the precise duration of exposure.

Comparison with Reichenstein

Córdoba Province is compared with Reichenstein, where arsenic poisoning and associated tumors had previously been a serious problem. Reichenstein was described as chiefly of historical interest after new water supplies were provided and arsenic was largely eliminated from them. Córdoba, by contrast, is cited as an ongoing example of chronic arsenic poisoning associated with contaminated water. The comparison makes water supply a consequential point of intervention, while distinguishing a largely historical case from an endemic one.

Relevance to pesticide exposure

The book uses Córdoba Province to warn that conditions resembling those in arsenic-contaminated communities could be produced through prolonged use of arsenical insecticides. The concern is therefore not confined to naturally arsenic-bearing rock: persistent human use of arsenic-based chemicals could also contribute to long-term contamination. Córdoba serves as evidence of the health consequences associated with chronic arsenic exposure, while the proposed parallel with insecticide use is framed as a possibility rather than as a claim that such an outcome had occurred there.
