Influence of the method of fluoride administration on toxicity and fluoride concentrations in Japanese quail Influence of the method of fluoride administration on toxicity and fluoride concentrations in Japanese quail

Young Japanese quail (Coturnix japonica) were administered NaF for 16 d either in their diet or by esophageal intubation. Based on the total fluoride ion (Σmg F−) intake over the 16-d experimental period, fluoride administered by intubation was at least six times more toxic than that fed in the diet. Dietary concentrations of 1,000 ppm F− (Σmg F− for 16 d = approx. 144) produced no...

Reproduction in black-crowned night-herons fed selenium Reproduction in black-crowned night-herons fed selenium

Agricultural and industrial practices can produce wastewater that contains high concentrations of selenium, a naturally-occurring trace element. Selenium entering aquatic systems through wastewater inflow can accumulate in aquatic food chains to levels that may be toxic to fish and wildlife species. Mallard reproduction is known to be adversely affected by 10 ppm selenium in the diet...
