Marine Mercury Bioaccumulation presents state-of-the-art research on mercury bioaccumulation in marine life. Written by leading experts in marine toxicology, this book delivers the latest information on monitoring and modeling mercury biomagnification in key marine taxa. Early chapters introduce the basic biology and ecology of how mercury travels through marine organisms and accumulates within marine food webs. Central chapters discuss the current status and exposure risks of key taxa, including marine vegetation, invertebrates, fishes, mammals, and birds. The book concludes with an assessment of human exposure to mercury through seafood products and novel modeling tools to assess environmental exposure risks and bioaccumulation.Users will find this to be a great resource for a global assessment of mercury contamination in the ocean, including biological resources, monitoring and modeling, current tools, existing research gaps, and suggestions on how to improve our monitoring and policy tools for improved safety of marine life and human consumption. This is an indispensable tool for researchers, resource managers, fisheries stakeholders, and students alike.Summarizes state-of-the-art research on mercury accumulation in marine biotaProvides a worldwide database on mercury concentrations and distribution in key marine taxaFeatures insights from global experts on current practices for mercury monitoring and pollution assessment

The last few decades have seen a rapid growth of interest in the mangrove ecosystems. This is due, on the one hand, to the perception that mangrove ecosystems are valuable resources, and, on the other hand, due to vested economic interests. There is an accelerated rate of destruction of mangroves worldwide. Almost all nations of the world tropical belt are concerned with the conservation of this natural wealth, but surreptitiously permit the misuse of mangroves for quick monetary returns unabatedly. The scientific community and decision makers of many nations are now in a state of alert, requesting sound directives for the sustainable use of mangroves worldwide. The present publication is an attempt to present in an organized manner the present state of knowledge which could be useful for decision makers and of interest to all those who see the ecological and economical potential of the various types of mangrove ecosystems.

Twenty contributions on diverse aspects of the environmental geochemistry in tropical and sub-tropical environments make up this monograph. They summarize original research not readily available elsewhere in the literature. Most of the chapters include extensive original data that will be very useful to researchers interested in the tropics and sub-tropics. A group of papers on methods and their applications is aimed directly at scientists involved in environmental research in the tropics. There are also some interesting intercontinental comparisons drawn on paleoclimatology, environmental impacts of mining and geochemistry of continetal shelf sediments.
