Book Description
The growing consumer interest in health and fitness has expanded the market for a wide range of products, from yoga mats to the multiple dietary supplements now on the market. Supplements are popular, but are they safe? Many dietary supplements are probably safe when used as recommended. However, since 1994 when Congress decided that they should be regulated as if they were foods, they are assumed to be safe unless the Food and Drug Administration can demonstrate that they pose a significant risk to the consumer. But there are many types of products that qualify as dietary supplements, and the distinctions can become muddled and vague. Manufacturers are not legally required to provide specific information about safety before marketing their products. And the sales of supplements have been steadily increasingâ€"all together, the various types now bring in almost $16 billion per year. Given these confounding factors, what kind of information can the Food and Drug Administration use to effectively regulate dietary supplements? This book provides a framework for evaluating dietary supplement safety and protecting the health of consumers.

Book Description
This volume of the IARC Monographs provides evaluations of the carcinogenicity of quinoline, styrene, and styrene-7,8-oxide. Quinoline and styrene are present in air pollution and in tobacco smoke. Quinoline also occurs in the processing of petroleum and shale oil, and is found in groundwater and soil at sites contaminated by coal tar and creosote. Quinoline and styrene are high production volume chemicals. Quinoline is used to produce various drugs and dyes. Styrene is primarily used in the production of polystyrene polymers. Styrene-7,8-oxide is primarily used to produce epoxy resins. Styrene-7,8-oxide is the primary metabolite of styrene in humans. Styrene and styrene-7,8-oxide are found in workplace air, particularly in the reinforced plastics industry and the rubber industry. Exposure to these agents may occur in the general population as well as in various occupational settings. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of environmental or occupational exposure to these agents.

Book Description
This volume of the IARC Monographs provides evaluations of the carcinogenicity of some organophosphate insecticides and herbicides, including diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos. Diazinon acts on a wide range of insects on crops, gardens, livestock, and pets, but most uses have been restricted in the USA, Canada, and the European Union since the 1980s. Glyphosate is the most heavily used agricultural and residential herbicide in the world, and has been detected in soil, air, surface water, and groundwater, as well as in food. Malathion is one of the oldest and most widely used organophosphate insecticides, and has a broad spectrum of applications in agriculture and public health, notably mosquito control. The insecticide parathion has been largely banned or restricted throughout the world due to toxicity to wildlife and humans. Tetrachlorvinphos is banned in the European Union, but continues to be used in the USA and elsewhere as an insecticide on animals, including in pet flea collars. The IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of these agents.
