Lead Accumulation and Depression on -Aminolevulinic Acid Dehydratase (ALAD) in Young Birds Fed Automotive Waste Oil

One-week-old mallard ducklings and pheasant chicks were fed automotive waste oil for a three week period to determine its effects on bird populations. The treatment groups consisted of birds exposed to 0.5, 1.5, or 4.5% waste crankase oil (WCO), to 4.5% clean crankcase oil (CCO), and untreated contr...

Description
Summary:One-week-old mallard ducklings and pheasant chicks were fed automotive waste oil for a three week period to determine its effects on bird populations. The treatment groups consisted of birds exposed to 0.5, 1.5, or 4.5% waste crankase oil (WCO), to 4.5% clean crankcase oil (CCO), and untreated controls. Red blood cell D-aminolevulinic acid dehydratase inhibited significantly after one week by 50-60% in the 0.5% wco groups and by 85-90% in the 4.5% wco groups due the presence of Pb. Plasma aspartate aminotransferase activity was higher in mallards after three weeks of ingesting either 4.5% wco or 4.5% cco, implying an oil-related effect due to components other than Pb. No effects were registered on plasma concentration or uric acid, gluscose, triglycerides, total protein, or cholesterol.
