CHEM 280: Chemistry of Water: Connecting Self, Society, and Environment at the Local Scale (Dr. Schwartz and Dr. Rostan)

With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the potential for seawater to become increasing acidic (i.e., ocean acidification). Scientists are concerned that increasing acidity could result in reduced growth or even death of shell-forming animals as well as disruption of marine food webs and reproductive physiology. Congress is beginning to focus attention on better understanding this issue and determining how it might be addressed. As well as examining the above issues, this book also presents an overview of the causes of hypoxia, the U.S. areas of most concern, federal legislation, and relevant research programs. In addition, this book reviews the history and oil spills in the United States; identifies the legal authorities governing oil spill prevention, response and cleanup; and examines the threats of future oil spills in U.S. coastal waters. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.

Dead zones are on the rise... Human activity has caused an increase in uninhabitable, oxygen-poor zones--also known as "dead zones"--in our waters. Oxygen is the third most abundant element in the universe, and it is a necessity for nearly all life on Earth. Yet many rivers, estuaries, coastal waters, and parts of the open ocean lack enough of it. In this book, David L. Kirchman explains the impacts of dead zones and provides an in-depth history of oxygen loss in water. He details the role the agricultural industry plays in water pollution, showcasing how fertilizers contaminate water supplies and kickstart harmful algal blooms in local lakes, reservoirs, and coastal oceans. Algae decomposition requires so much oxygen that levels drop low enough to kill fish, destroy bottom-dwelling biota, reduce biological diversity, and rearrange food webs. We can't undo the damage completely, but we can work together to reduce the size and intensity of dead zones in places like the Gulf of Mexico, Chesapeake Bay, and the Baltic Sea. Not only does Kirchman clearly outline what dead zones mean for humanity, he also supplies ways we can reduce their deadly impact on human and aquatic life. Nutrient pollution in some regions has already begun to decline because of wastewater treatment, buffer zones, cover crops, and precision agriculture. More needs to be done, though, to reduce the harmful impact of existing dead zones and to stop the thousands of new ones from cropping up in our waters. Kirchman provides insight into the ways changing our diet can reduce nutrient pollution while also lowering greenhouse gasses emitted by the agricultural industry. Individuals can do something positive for their health and the world around them. The resulting book allows readers interested in the environment--whether students, policymakers, ecosystem managers, or science buffs--to dive into these deadly zones and discover how they can help mitigate the harmful effects of oxygen-poor waters today.

Times are tough for shrimpers and fishers in the Gulf of Mexico. The animals they rely on for their livelihood are harder to find. Every summer a dead zone--a region of low oxygen--emerges in the waters along the Gulf Coast. Where oxygen is low, fish and others animals cannot survive. Currently the world has more than 400 identified dead zones, up dramatically from the 49 dead zones identified in the 1960s. The good news is that people can eliminate dead zones by changing agricultural practices and reducing pollution. Using real-world examples, this book looks at the impact of pollution on global water resources, and discusses the interconnectedness of ecosystems and organisms.

Marine pollution occurs today in varied forms--chemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we've seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutants and the many ways they can come to harm our environment and our bodies. In Marine Pollution: What Everyone Needs to Know, Judith Weis covers marine pollution from numerous angles, each fascinating in its own right. Beginning with its sources and history, she discusses common pollutants, why they are harmful, why they cause controversy, and how we can prevent them from destroying our aquatic ecosystems. Questions ask what actually happened with the Exxon Valdez, and why harmful algal blooms are a serious concern. Covering pollutants that are only now surfacing as major threats, such as pharmaceuticals, personal care products, and metal nanoparticles, she explains how these can begin in the water and progress up the food chain to emerge in human bodies. Looking at the effects of climate change and acidification on marine pollution levels, we learn how we can begin to reduce pollution at the local and global levels.

The study of marine environments inevitably involves considering the problem of marine pollution, which includes questions that focus on the essential need to ensure the long-term health of these exceptional ecosystems and the lives and livelihoods they support. The open access textbook "Marine Pollution: monitoring, management and mitigation" approaches these questions in a practical and highly readable format. It gives newcomers to the field background and perspective through the first comprehensive, multidisciplinary exploration of the topic. The topic is indeed complex, requiring the integration of the natural sciences and chemistry with management, policymakers, industry and all of us who are users of the marine environment.
