 The risk of mercury exposure through consumption of fish from Camarines Norte, Philippines was investigated. A total of 34 people were surveyed to know their fish consumption levels. In the study areas, Bugitis, Hipon, Galunggong, Matangbaka, Dilis, Danggit, Pak-an, Bagongon, Alimango, Dalag and Palos are common staples in the residents’diet. Exposure to mercury was calculated on the basis of weekly consumption vis-a-vis body weight. The result for the worst scenario indicated that attention should be paid to several species. Possible safe consumption levels of these fishes were also calculated for the inclusive health management of the local government unit.

 貝化石および多孔質セラミックスを用いて土壌中の金属および金属イオンを除去する目的でカドミウム吸着試験を行った結果,吸着能力が認められた.希釈したカドミウム(濃度1 ppm)水溶液に資材を投入し,5 分毎に水溶液中のカドミウム濃度を分析した.貝化石T,貝化石N,多孔質セラミックスG の順序で高い資材の吸着能力を確認した.全ての資材において吸着速度は非常に速く,カドミウム水溶液の中へ資材を投入5 分後にカドミウムは吸着し,その後50 分後までモニタリングした結果10 分で吸着はほぼ平衡に達した.さらに,吸着には温度依存性があることが確認された.また多孔質セラミックスGについて,吸着能力が低くなったのは水溶液のpH が低かったためと思われる.

Increasing Profitability through Responsibility in the Luxury Industry
Harriet KELSALL
 Younger millennial customers in particular no longer automatically trust that brands operate responsibly; global research shows many believe they need to spend carefully, choosing companies making a positive difference to improve the future. They ask new questions and want companies to be efficient with environmental resources and kind to people in their teams and supply chains. Furthermore, in the midst of a global trust crisis, there is a growing reputational risk and luxury companies could be exposed in the media if they are not behaving responsibly or are ‘Greenwashing’.
 In 1998, Harriet Kelsall started a business with strong ethical foundations and they were initially surprised to find that this aspect enhances their brand and helps them to make money. Within the model, they sell Fairtrade gold, are audited by the Responsible Jewellery Council and use materials mined as responsibly as possible. They are as transparent as possible explaining to customers that not everything can yet be ethically prefect because the industry is still on a journey towards improved responsibility and customers respect thistruth and honesty about what they can and can’t do.
 This paper presents a visual representation of this successful small business showing how they interact with each community: suppliers, customers, social initiatives, education, employment, business and media. This business is profitable and pays good wages, proving that even a small business can be both ethically minded and luxurious. Harriet believes that jewellery companies need to support the Minamata convention and platforms like Fairtrade, Fairmined and the Responsible Jewellery Council. Luxury must be aligned with fairness, not only to change the landscape and the roots of supply, employment and business for future generations but also because this leads to enhanced profits and mimimises reputational risk.
