Biokinetic food chain modeling of waterborne selenium pulses into aquatic food chains: Implications for water quality criteria

Food Quality Standards: Quality Issues and Challenges of Food Chain in Burkina Faso

Background: In Burkina Faso, the agricultural sector accounts for 35% of the gross domestic product (GDP) and employs 82% of the active population. The agri-food industries must apply the requirements of the management systems to improve their economic position and ensure sustainable development. The present study aimed to highlight the similarities and particularities of these repositories gro...

Light Dependence of Selenium Uptake by Phytoplankton and Implications for Predicting Selenium Incorporation into Food Webs

The potentially toxic element selenium is first concentrated from solution to a large but highly variable degree by algae and bacteria before being passed on to consumers. The large loads of abiotic and detrital suspended particles often present in rivers and estuaries may obscure spatial and temporal patterns in Se concentrations at the base of the food web. We used radiotracers to estimate up...

Material Inventory Optimization in Bakery Supply Chain: Implications for Food Security in Nigeria

The study determined optimum inventory levels for various bakery resources using the bread supply chain network in Onitsha City. Structured questionnaires were administered among bakery factories. The optimum design achieved through the optimization model was compared with the existing systems. Analysis of 90 bakeries with a combined capacity of 3960 revealed that total money N 564,408,477.28 i...

Comparison of aquatic food chains using nitrogen isotopes.

Recent studies have shown the utility of delta(15)N to model trophic structure and contaminant bioaccumulation in aquatic food webs. However, cross-system comparisons in delta(15)N can be complicated by differences in delta(15)N at the base of the food chain. Such baseline variation in delta(15)N is difficult to resolve using plankton because of the large temporal variability in the delta(15)N ...
