Abstract:
Mercury is a collection of short stories based in the fictional town of Mercury, Georgia. Set over the course of several decades, the stories trace the events that changed individuals, families, and a whole community for decades. Loosely based on the author's real-life family history, the stories, both humorous and heartbreaking, show characters caught between the past and the present and searching for a way forward. A girl who makes friends with a ghost, a woman who can't help but run from crying babies, a man forced to face the town's darkest side—these and other characters respond in surpri

Les tourbières sont communément utilisées comme archives de dépôts de mercure (Hg). De nombreuses études ces dernières décennies ont montré que les taux d’accumulation de Hg (HgARs) ont augmenté en réponse à l’industrialisation. Les signatures isotopiques en Hg se révèlent très utiles pour mieux caractériser les dépôts de Hg. Elles ont permis de montrer que les dépôts secs de Hg élémentaire gazeux (GEM) dominent les dépôts de Hg sur la tourbière du Pinet.

This thesis examines the production and distribution of dissolved gaseous mercury (DGM) in freshwater ecosystems and its relationship to mercury volatilization.

The magnitude of volatilization was found to be approximately double the direct wet deposition over lake and wetlands, and 27% of the direct wet deposition to the terrestrial catchment. Over the entire basin area the mass of mercury volatilized is 46% of the mass deposited by wet deposi

The pseudo-first-order rate constant (k) for photoreduction reaction is pH-dependent. Similar results were obtained using visible irradiation although the rates were ca. 10 times slower.
