Regulation Through Revelation: The Effect of Pollution Monitoring on Labour Demand

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates how manufacturing firms respond to a real‐time pollution monitoring programme, with a focus on the implication for employment. Contrary to the conventional expectation that environmental regulations negatively impact business, the findings reveal that enhanced pollution monitoring has a significant and robust positive ...

Redox‐Dependent Luminescence in a Pentavalent Uranyl Complex

ChemistryEurope, EarlyView.
Redox‐dependent luminescence in a molecular pentavalent uranyl complex supported by a pyridine dipyrrolide pincer ligand is presented. Electrochemical and chemical reduction of the uranyl(VI) species provides a stable uranyl(V) complex that emits blue light from a high‐energy excited state. The anti‐Kasha emission is credited to the presence of “nested”

Improved atmospheric sampling of hexavalent chromium [PDF]

Journal of the Air & Waste Management Association, 2013
Hexavalent chromium (Cr(VI)) and trivalent chromium (Cr(III)) are the primary chromium oxidation states found in ambient atmospheric particulate matter. While Cr(III) is relatively nontoxic, Cr(VI) is toxic and exposure to Cr(VI) may lead to cancer, nasal damage, asthma, bronchitis, and pneumonitis.
