Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...

Oil Futures Prices, Inflation Expectations, and Bond Risk Premiums

Journal of Futures Markets, EarlyView.
ABSTRACT By decomposing West Texas Intermediate futures price changes into structural supply and demand shocks, this paper shows that dissecting the oil price significantly improves inflation forecasts. Empirically, demand‐driven shocks predict a negative real bond risk premium but a positive inflation risk premium; these opposing effects result in an ...

On the Comovement of Contango and Backwardation Across Futures Commodity Markets

Journal of Futures Markets, EarlyView.
ABSTRACT We examine the time‐varying nature of the comovement of the slope of the futures curve in major agricultural, metals and energy commodity futures markets in a Global Vector Autoregressive model. We find significant comovement between the slopes, indicating the co‐existence of backwardation and contango in many seemingly unrelated commodity ...
