  • Copper fungicides are environmentally unfriendly. They are very toxic to fish and aquatic invertebrates, such as crab, shrimp and oysters. There are cases where most animal life in soil, including large earthworms, have been eliminated by the extensive use of copper-containing fungicides in orchards. It is strongly bioaccumulated and is very persistent. Once a soil is contaminated with copper, there is no practical way to remove it. The organic insecticide rotenone has been found to be toxic to pigs, rats and dogs and is is very toxic to fish. It causes skin and eye irritations.

  • Pharmacokinetic Interactions Causing Decreased Drug Effects Gastrointestinal absorption can be reduced if a drug interaction results in drug binding in the gut, as with aluminum-containing antacids, kaolin-pectin suspensions, or bile acid sequestrants. Drugs such as histamine H 2 receptor antagonists or proton pump inhibitors that alter gastric pH may decrease the solubility and hence absorption of weak bases such as ketoconazole.
