Question

BlackTom AI · Accepted Answer

The question asks which of the listed items is among the Dirty Dozen and was widely used as a pesticide in the U.S. before being found harmful to wildlife, especially birds, and subsequently banned.
Option 1: Cryptosporidium. This is a protozoan parasite that causes cryptosporidiosis and is not a pesticide, nor part of the Dirty Dozen pesticides. Its relevance here would be about waterborne illness, not chemical residues in wildlife.
Option 2: coal ash. Coal ash is a byproduct of burning coal and contains various heavy metals; while environmental contamination is a concern, it has not been classified as one of the Dirty Dozen pesticides and it was not widely used as a pesticide in the U.S. prior to a ban.
Option 3: Nitrate fertilizer. Nitrates are agricultural fertilizers associated with water quality issues like eutrophication, but they are not pesticides and they were not banned as a pesticide for harming wildlife. This option confuses a fertilizer with chemical pesticides.
Option 4: DDT. DDT (dichlorodiphenyltrichloroethane) is the well-known pesticide that was widely used in the United States for decades, was found to harm birds (e.g., thinning eggshells in birds of prey), and was banned in the U.S. in the 1970s. This clearly fits the description of the Dirty Dozen context and the historical ban.
In summary, the only option that matches the described scenario—widely used as a pesticide, harmful to wildlife, and later banned—is DDT. The other options refer to substances or categories not aligned with the Dirty Dozen pesticides or with the historical ban narrative.
