Heavy metals are a global concern due to their potential toxic effects and ability to bioaccumulate in aquatic ecosystems. Toxic heavy metals, such as mercury (Hg), cadmium (Cd), and lead (Pb), copper (Cu) and zinc (Zn) etc. are harmful to eco-environments and human beings, which causes different types of problems including cancer. Fish is one of the important sources of protein for humans in our daily life, specially in South-Asian countries. But unfortunately, a significant amount of all those toxic elements are being bio-accumulated in fish body and eventually entering into human body through the food chain. However, contents of this book discussed a series of chapters on human health risk (non-cancer risk and cancer risk) assessment due to heavy metals contamination have been addressed following US-EPA health risk models. From the human health point of view, the authors have been suggested that there is no possible health risk to the consumers due to intake of the studied fishes and shellfishes under the current consumption rate. This book should be used as a model book for assessment of human health due to consumption of different fish species in any industrial coastal zone.

This is the only book that takes a zero-waste approach to propose 100% sustainable water purification techniques. Water is synonymous with life. This has been the case since pre-historic time to the modern era. For the first time, humanity faces a crisis that eclipses the energy crisis, which has often incapacitated the global economy. The Climate-Water-Food nexus epitomizes our current civilization that depends on energy as the driver. Many recognize this crisis as a product of fossil fuel production, which allegedly triggered climate change and the "climate change debate." Others predict the onslaught of "water wars" in the coming decades. As the world gears up to another lineup of empty promises and ensuing chaos, this book turns this crisis on its head and shows the source of the water crisis. The science behind the water cycle is described in clear language, without resorting to dogmatic assertions and spurious assumptions. The role of the sun, natural carbon dioxide (CO2) and water and the need to maintain natural processes free from artificial chemicals are discussed in detail. The book makes it clear how most of the currently used purification techniques violates the natural cycle involving sunlight, CO2 and water, and thus become unsustainable. A series of water purification techniques, as usable for drinking, agricultural and industrial applications are presented. The advantages of these techniques and their long-term sustainability are highlighted, with discussion on improvements in the future. Whether for the engineer or scientist working in the field or laboratory or the student, this is a must-have for any engineer, scientist, student, or policymaker. This breakthrough new volume: Points out shortcomings of existing purification techniques Delves into the root causes of water pollution Identifies water purification techniques that are wholly sustainable Presents a recipe for lifestyle change for creating a culture of sustainable living

This is the second volume in a four-volume series aimed at guiding the pharmaceutical industry toward sustainability. After analyzing and exposing some of the backward and ill-conceived notions that guide the present state of the industry, this volume presents key theories and new, groundbreaking solutions for re-thinking the processes involved in the engineering of pharmaceuticals and offers a fundamental paradigm shift.The 4 volumes in this ambitious project are:* Volume 1: Practice, Analysis, and Methodology* Volume 2: Theories and Solutions* Volume 3: Applications for Mental Disorder Treatments* Volume 4: Applications for Physical Disorder TreatmentsThis ground-breaking set of books is a unique and state-of-the-art study that only appears here, within these pages. A fascinating study for the engineer, scientist, and pharmacist working in the pharmaceutical industry and interested in sustainability, it is also a valuable textbook for students and faculty studying these subjects.

The pharmaceutical industry is one of the most important industries in the world, offering new medicines, vaccines, and cures to a global population. It is a massive industry, worthy of a deep and thorough examination of its processes and chemistry, with a view toward sustainability.
