Urban environments have a history of anthropogenic input of heavy metals to soils. Toledo, Ohio is an urban setting that has been altered through heavy industry and transportation dating back to the 1800s. Heavy metal contamination in soil has been shown to cause serious health effects in humans, such as brain damage, birth defects, cancer, and even death.A total of 137 Toledo soil samples were collected in collaboration with local Toledo schools, the Manos Community Garden, and a previous study completed by Stewart et al (2014). Stewart's study samples and the local Toledo schools' soil samples were collected by K-12 students through a hands-on citizen science project. The samples were analyzed to determine the concentrations of a series of heavy metals, including arsenic, cadmium, chromium, lead, nickel, and zinc. The results revealed multiple samples with elevated levels of all six focus metals greater than the Ohio EPA's soil background levels of the region. Two of these elements, arsenic and lead, had concentrations higher than the USEPA screening level for soils of this region in 73% and 7% of samples, respectively. Locations with elevated heavy metals concentrations in soils were mostly residential yards with older houses and within areas of high transportation. Therefore, the elevated levels of heavy metals were likely deposited from a legacy of human activities. Heavy metal predictive concentration maps of the Toledo, Ohio area were created to show possible areas of concern. The predictive maps showed a higher concentration of most elements in the Old West End area of Toledo. The findings were presented to the collaborating schools and in public forums to educate citizens about elevated heavy metal soil contamination in their area. They were given possible reasons for the contamination, explaining the harmful side effects of human activities on the soils. The health risks associated with the contamination were presented along with how to prevent health issues and how to take precautions around heavy metals.

In the industrial era, the most important potential threat to crop production is abiotic stress, including toxic metal/metalloid stress. Growing populations and rapid industrialization lead to the generation and release of huge amounts of toxic metals/metalloids into the environment, altering plant physiological processes and reducing yields. In the last few decades, there has been extensive research to elucidate the mechanisms of tolerance to metal/metalloid toxicity and ways to improve the defense system in plants. Use of exogenous photoprotectants such as osmoprotectants, plant nutrients, phytohormones, signaling molecules, antioxidants, amino acids and organic acids are widely being used to improve plants’ tolerance to metal/metalloid stress. Recently, phytoremediation approaches have been effectively employed to remediate metal/metalloid pollution. This book presents the latest insights into plant responses and tolerance in plants grown under metal/metalloids stress to provide a better understanding of the topic and the future outlook.

Urban Ecology: An Introduction seeks to open the reader’s mind and eyes to the way in which nature permeates everyday urban living, and how it has to be understood, cared for, and managed in order to make our towns and cities healthier places to visit and in which to live and work. The authors examine how nature can improve our physical and mental health, the air we breathe and the waters we use, as well as boosting our enjoyment of parks and gardens. Urban Ecology sets out the science that underlies the changing natural scene and the tools used to ensure that cities become both capable of adapting to climate change and more beautiful and resilient. The book begins with a discussion of the nature of urban places and the role of nature in towns and cities. Part 1 looks at the context and content of urban ecology, its relationship to other foci of interest within ecology and other environmental sciences, and the character of city landscapes and ecosystems. In Part 2 the authors set out the physical and chemical components of urban ecosystems and ecological processes, including urban weather and climate, urban geomorphology and soils, urban hydrology and urban biogeochemical cycles. In Part 3 urban habitats, urban flora and fauna, and the effects of, deliberate and inadvertent human action on urban biota are examined. Part 4 contains an exploration of the identification and assessment of ecosystem services in urban areas, emphasising economic evaluation, the importance of urban nature for human health and well-being, and restoration ecology and creative conservation. Finally, in Part 5 the tasks for urban ecologists in optimising and sustaining urban ecosystems, providing for nature in cities, adapting to climate change and in developing the urban future in a more sustainable manner are set out. Within the 16 chapters of the book – in which examples from around the world are drawn upon - the authors explore current practice and future alternatives, set out procedures for ecological assessment and evaluation, suggest student activities and discussion topics, provide recommended reading and an extensive bibliography. The book contains more than 150 tables and over 150 photographs and diagrams.

Coal Combustion Byproducts and Environmental Issues addresses the major implications and critical issues surrounding coal combustion products and their impact upon the environment. It provides essential information for scientists conducting research on coal and coal combustion products, but also serves as a valuable reference for a wide variety of researchers and other professionals in the energy industry and in the fields of public health, engineering, and environmental sciences. The ultimate goal of this volume is to benefit both our economy and our environment as humanity enters the second half of the fossil fuel era.
