In April 2012, the NOAA Ship Okeanos Explorer conducted the first reconnaissance of a shipwreck site 275 km from the Texas-Louisiana coast as part of an interdisciplinary exploration mission focusing on deepwater hard-bottom habitat, naturally occurring gas seeps, and potential shipwrecks in the Gulf of Mexico. First identified as a side-scan sonar target in 2011 by Shell Oil during a lease-area survey, a brief ROV dive imaged the undisturbed, early nineteenth century wooden-hulled, copper-sheathed sailing vessel containing artillery, firearms, navigation instruments, cooking and food storage items, medicines, and personal effects. \"Monterrey A\" is one of the more significant shipwrecks discovered in the Gulf of Mexico to date because of its degree of preservation and the insight it provides into a critical period in history when new nations were forming at the end of Colonial period and the Gulf of Mexico was opening to global trade.

Marine historical ecology powerfully frames ocean issues. It reveals rich new storylines and opportunities for new constituencies in the public to identify with a specific place or time in history. Historical anecdote, personal experience, and imagery, which are less polarizing than some conservation messages, can create interest among people who may not naturally care about fish, the sea, or the health of the marine environment. Using the concept of framing, this chapter describes mechanisms to engage the public via old and new media. Exciting the imagination on an individual level, marine historical ecology can create a sense of ownership and

Marine historical ecology powerfully frames ocean issues. It reveals rich new storylines and opportunities for new constituencies in the public to identify with a specific place or time in history. Historical anecdote, personal experience, and imagery, which are less polarizing than some conservation messages, can create interest among people who may not naturally care about fish, the sea, or the health of the marine environment. In this chapter, using the concept of framing, Catherine Marzin, Sian Evans, and Karen Alexander describe mechanisms to engage the public via old and new media. Exciting the imagination on an individual level, marine historical ecology can create a sense of ownership and recognition of the need for ocean stewardship. New outreach strategies can be developed, utilizing all the tools of new media including discoverability, social participation, and mobility. Historians and scientists can harness the power of history and scientific observation in new arcs of storytelling across new media platforms—social, textual, and visual.

Objectives to assess environmental and biological monitoring of exposure to organic solvents in a glue-manufacturing company in Sfax, Tunisia. Methods Exposure of volunteer workers, in the solvented glue-work-stations, in the control laboratory and in the storage rooms of the finished products, was assessed through indoor-air and urine measurements. Informed consent of the workers was obtained. Results and discussion The exposure indexes were found with high values in the solvented workshop as well as in the control laboratory and were respectively, 8.40 and 3.12. These indexes were also correlated with hexane and toluene indoor air concentrations. As to urine, the obtained results for the 2,5-hexandione and hippuric acid, metabolites of hexane and toluene, respectively, were in accord with the indoor-air measurements, with an average of 0.46 mg/l and 1240 mg/g of creatinine. Conclusion This study assessed for the first time biological exposure to organic solvents used in Tunisian adhesive industries. Although values are likely to underestimate true exposure levels, some figures exceed European and American occupational exposure guidelines.

The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids of the European Food Safety Authority was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (the JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. The present consideration concerns a group of 12 aliphatic amines and amides evaluated by the JECFA at the 68th meeting in 2007. This revision of the consideration is made due to additional toxicity data available for two substances, N‐3, 7‐dimethyl‐2, 6‐octadienyl cyclopropylcarboxamide [FL‐no: 16.095] and N‐[(ethoxycarbonyl)methyl]‐p‐menthane‐3‐carboxamide [FL‐no: 16.111]. The substances were evaluated through a stepwise approach that integrates information on structure‐activity relationships, intake from current uses, toxicological threshold of concern and available data on metabolism and toxicity. The Panel agrees with the application of the Procedure as performed by the JECFA for 11 of the substances considered in this FGE and agrees with the JECFA conclusion, “No safety concern at estimated levels of intake as flavouring substances” based on the MSDI approach. For one substance [FL‐no: 16.090] additional toxicity data are still needed before the evaluation can be finalised. Besides the safety assessment of these flavouring substances, the specifications for the materials of commerce have also been considered and for one substance, [FL‐no: 16.090], the composition of the stereoisomeric mixture has to be specified.
