The manufacture of plastic as well as its indiscriminate disposal and destruction by incineration pollutes atmospheric, terrestrial, and aquatic ecosystems. Synthetic plastics do not break down; they accumulate in the environment as macro-, micro-, and nanoplastics. These particulate plastics are a major source of pollutants in soil and marine ecosystems. Particulate Plastics in Terrestrial and Aquatic Environments provides a fundamental understanding of the sources of these plastics and the threats they pose to the environment. The book demonstrates the ecotoxicity of particulate plastics using case studies and offers management practices to mitigate particulate plastic contamination in the environment.Features· Describes physical and chemical properties of particulate plastics in terrestrial and aquatic ecosystems· Presents information on characteristics of particulate plastics as impacted by weathering processes· Provides numerous approaches for managing particulate plastic contamination· Identifies sources of particulate plastics in the environment; distribution and characteristics of particulate plastics; and management strategies of particulate plasticsWritten by a global team of scientists, this book is for researchers in the fields of environmental safety and waste management or individuals interested in the impact of particulate plastics on environmental health.

The textbook Climate Change and Agricultural Food Production: Impacts, Vulnerabilities and Remedies provides an extensive overview of the effects of climate change on all sectors of agricultural food production, including agriculture, livestock, and fisheries. It also covers food contamination and food safety, including microbial pathogens, toxic biological, and toxic chemical contaminants, as well as food security and measures to adapt to and mitigate the impacts of climate change on these sectors. The book presents information from research results and data from around the world, including Africa, Asia, Australia, Europe, Latin America, North America, the Polar Regions, and Small Island Nations. It has been designed as a textbook, reference book, and extension book, and is written in simple and plain English, with key facts, acronyms, and a glossary provided in each chapter, along with tables and figures to benefit a wide range of readers.

The book is an attempt to address the important facts and figures relating to climate change impacts on water security: a. Climate change impacts on water resources; b. Climate change impacts on water related diseases; c. Climate change impacts on water dependent biodiversity and ecosystems; d. Climate change adaptation and mitigation measures for water security; and e. Climate change and greenhouse gas emissions from water sector.Climate change is an additional stress on water security in addition to other chemical and biological stressors.Rivers depending on the Himalayan glaciers (the Indus, Ganges, Brahmaputra) could face water shortages or reduced river run-off due to retreat of glaciers, and this would cause dramatic impact on drinking water supplies, biodiversity, hydropower generation, industry, agriculture, ecosystems on which about 2.4 billion people in Asia depends.As a consequence of drought, the annual stream flow in the Murray-Darling basin (Australia) is projected to fall by 10-25% by 2050 and 16-48% by 2100 which would have severe consequences on irrigated agriculture in the region.Rise of water temperatures may enhance proliferation of harmful algae (some of algae produce toxins), causing water quality problems for recreational activities, fisheries/fish farming, irrigation, and drinking and seafood contamination with algal toxins.Global warming is projected to increase river water temperatures in a number of countries including the USA (the Mississippi, Colorado, and Mackenzie basins), Europe (the Rhine, Danube, and Rhone basins), eastern China (the Yangtze), and Australia (the Murray-Darling).Sea-level rise (SLR) will cause salinization of coastal groundwater resources, and may damage or destroy many coastal ecosystems including wetlands, salt marshes, and may cause saline water intrusion in agriculture and freshwater aquaculture facilities, a shift in community composition of mangrove forests, etc.It is projected that a 1°C rise of temperature in the future can increase the initial relative risks of cholera by 15 to 29 percent. Both rise of temperature and sea-level may enhance dengue and malaria.To adapt to climate change, we need increasing storage capacity, rainwater harvesting, improvement of water use efficiency, desalination of seawater, water savings, mandatory rainwater tanks in new and old buildings, use of recycled/reclaimed water, virtual water trade, improvements in irrigation efficiency, modification of irrigation techniques, reducing leakage of irrigation pipes, selection of climate resilient crops to save scarcity of water resources.Water processes (abstraction, treatment, end use and wastewater treatment) do emit Greenhouse gases (GHG). In irrigation, pumping of water is the most energy-demanding process and consequently causes more GHG emissions (CO2). Dams/reservoirs emit GHGs such as methane.The most effective way to decrease carbon footprint in water sectors is to use low carbon emitting fuels such as, renewable energy (solar, wind or nuclear). Ecological toilet may be promoted to reduce GHG emissions from septic tanks in developing countries.Stopping or slowing deforestation, forest degradation and sustainable management of forests may significantly contribute to avoid GHG emissions, may conserve water resources and prevent flooding, reduce run-off, control erosion, reduce siltation of rivers, and protect fisheries and preserve biodiversity.Mangrove ecosystems can play an important role in the protection of the coast from the natural disasters (cyclones, tsunamis) and could act as a barrier (live seawalls) against disasters and help minimize damage to property and life.

The book Climate Change and Chemicals - Environmental and Biological Aspects has addressed the two key environmental issues : climate change and chemical impacts on human health, environment and agricultural production with reference to chemistry, Ecotoxicology, toxicology, and biology. The book reviewed and summarised research results and information from both developed and developing countries including Asia-Pacific, Australasia and other parts of the world. Part-1 of the book Climate Change Impacts provides an account of greenhouse gases (carbon dioxide, methane and nitrous oxide) and its relationships with climate change and likely impacts on water resources, agriculture and livestock, fisheries and aquatic ecosystems and human health. The key data and information provided in Part-1 are as follows: Climate change and greenhouse gases: Carbon dioxide emissions from different countries of the world; measures to reduce greenhouse gas emissions including key mitigation technologies; and projections for future climate changes (temperatures and sea levels; precipitation; glaciers and cyclones) and Kyoto protocol and Copenhagen Accord (COP 15). Water resources: World freshwater resources and projections for future climate change impacts on water resources (surface waters; floods and droughts; ground water; water quality; snows and glaciers melting; sea level rise; shared water resources) and adaptation measures. Agriculture and livestock : Future worlds agricultural and livestock production relating to climate changes (enhanced CO2 effect on C3 and C4 plants/crops; effects of higher temperature; precipitation, water availability, irrigation; extreme events and climate variability; sea level rise; and pests and diseases) and adaptation measures. Fisheries and aquatic ecosystems : Effects of climate change on world fisheries and aquaculture production and projected impacts on freshwater, marine and terrestrial ecosystems (rising temperatures, dissolved oxygen and hypoxia; toxicological effects of contaminants; rising CO2 and acidification of oceans; rising temperatures and fish growth and fish recruitment) and adaptation measures.
