Long‐Term Ambient Benzene Exposure and Brain Disorders Among Urban Adults: Effect Modification by Genetic Susceptibility and Potential Mediation by Plasma Proteins

Advanced Science, EarlyView.
Low‐level ambient benzene exposure is associated with increased risks of multiple brain disorders in urban adults. Genetic susceptibility modifies these associations, while plasma proteomics points to potential biological pathways linking benzene exposure to adverse brain health.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Climate-driven spatiotemporal dynamics and exposure risks of global soil moisture drought–flood abrupt alternation events

Environmental and Sustainability Indicators
Drought–flood abrupt alternation (DFAA) events, characterized by rapid transitions between drought and flood conditions, pose severe challenges to agricultural production, water resource management, and infrastructure systems. While previous studies have

Assessing Household Welfare in Response to Rising Food Prices in The Gambia

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines how rising food prices affected household welfare in The Gambia using nationally representative data from the 2015/16 Integrated Household Survey (IHS‐3). The analysis reflects household consumption behavior and market conditions prevailing during that period and provides a structural benchmark for understanding ...

Evaluation of Cr(VI) Removal from Tanning Effluents Using Magnetic Nanoparticles of Fe₃O₄ Synthesized with Olea europaea Bone Extract

Molecules
The tanning industry generates effluents with high chromium content, which require treatment prior to discharge into the sewage system. This article explores the use of magnetic magnetite nanoparticles (MNPs) to remove Cr(VI) from aqueous solutions, such

On the Economics of US Agricultural Policy

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper presents an economic analysis of US agricultural policy, building on a modified version of Gardner's efficient redistribution. We argue that agricultural policy is motivated as an attempt to implement an efficient redistribution scheme that redistributes income toward farmers who, as a group, have been adversely affected by ...

Drought and Extreme Heat Reduce Wheat and Maize Production in the United States by Lowering Both Crop Yields and Harvestable Fraction

Earth's Future
Ensuring food security is crucial in the context of climate change and increased extreme weather events. Crop production depends not only on yield but also on the harvestable fraction (HF), the ratio of harvested areas to planted areas. While the impacts
