Topics include: Cocaine intoxication, Carbon monoxide poisoning, Update on miscellaneous drug overdoses, Toxidromes, Cardiac glycoside toxicity, Acetaminophen overdose, Envenomations, Methanol and ethylene glycol ingestion, and Toxicologic causes of ketoacidosis.

Past and future development as well as possibilities for influencing the process of retirement are discussed, in particular effects on the labour market (supply and demand, behaviour of workers and firms, concerning human resource management and occupational pensions), financing of social security and income of workers. Decisions concerning earlier or postponed, full or partial retirement are the main topic stressing the central role of firms' decisions depending e.g. on their view of the productivity of the elderly. Reports on Scandinavian countries (Sweden, Denmark, Finland) in particular on their approach for partial retirement are included as well as papers discussing possibilities to stop the trend of early exit from the labour force and how to give incentives for a longer working life (e.g. by changes in social security). These topics are discussed in the view of structural changes in demography, economy and society, using - among other - the US and West Germany as examples. The papers point out the necessity to look at retirement as a process (in a life cycle perspective, requiring longitudinal data for empirical research) and in a perspective integrating the different aspects involved.

Mit zunehmender UEberalterung der Bevoelkerung kommt den Problemen der psychiatrischen Alterspathologie eine standig wachsende Bedeutung zu. Deshalb ist diesem Thema erstmals im Rahmen der Psychiatrie der Gegenwart ein eigener Band gewidmet, der alle Aspekte der Alterspsychiatrie (Gerontopsychiatrie) umfassend abhandelt. Die Alterspsychologie, die Klinik, das Demenzproblem, die Psychotherapie, die Pharmakotherapie, aber auch Versorgungsprobleme und Fragen der Sterbehilfe werden von kompetenten Fachleuten nach dem heutigen Kenntnisstand dargestellt.

Congress has long deliberated on the condition of drinking water infrastructure and drinking water quality as well as the financial and technical challenges some public water systems face in ensuring the delivery of safe and adequate water supplies. Several events and circumstancesaincluding source water contamination incidents; water infrastructure damage from natural disasters, such as hurricanes; detection of elevated lead levels in tap water in various cities and schools; and the nationwide need to repair or replace aging drinking water infrastructureahave increased national attention to these issues. America's Water Infrastructure Act of 2018. Chapter 1 focuses on the drinking water provisions of Title II and Title IV of AWIA, which authorize appropriations for several drinking water and wastewater infrastructure programs for projects that promote compliance, address aging drinking water infrastructure and lead in school drinking water, and increase drinking water infrastructure resilience to natural hazards. Chapter 2 summarizes the Safe Drinking Water Act (SDWA) and its major programs and regulatory requirements. The quality of water delivered by public water systems has been regulated at the federal level since enactment of the 1974 Safe Drinking Water Act (SDWA). Since then, the U.S. Environmental Protection Agency (EPA) has issued regulations for more than 90 contaminants, and all states (except Wyoming) have assumed primary responsibility for administering the federal drinking water program and overseeing public water system compliance. Congress last broadly amended the law in 1996. Among the key provisions, the 1996 amendments authorized a Drinking Water State Revolving Fund (DWSRF) program to help public water systems finance improvements needed to comply with federal drinking water regulations and to address the most serious risks to human health as reported in chapter 3. Drinking water contaminated with lead in Flint, Michigan, renewed awareness of the danger lead poses to the nation's drinking water supply. Lead exposure through drinking water is caused primarily by the corrosion of plumbing materials, such as pipes, that carry water from a water system to pipes in homes. EPA set national standards to reduce lead in drinking water with the Lead and Copper Rule (LCR). Chapters 4-7 review the issue of elevated lead in drinking water. According to DOD, about 3 million people in the United States receive drinking water from DOD public water systems, which are to comply with EPA and state health-based regulations. EPA and DOD have detected elevated levels of two unregulated, DOD-identified emerging contaminants found in firefighting foamaPFOS and PFOAain drinking water at or near installations. Perchlorate, an unregulated chemical used by DOD in rocket fuel, can also be found in drinking water. Chapters 8-11 review DOD management of these drinking water contaminants.
