Scientific Issues

Consideration of multiple exposure routes is even more important in animal inhalation studies, because chemicals may be accumulated in fur, and also might be 

Each of these issues must be considered in interpretation of cancer potency data, from which standards for exposure to chemicals in air (or other routes) could be derived. However, utilization of these data in development of air standards presents many further challenges, as discussed below.

Forensic science is an applied science having a focus on practical scientific issues that come up during criminal investigations or at trial. Some components ate unique to the field because it is conducted within the legal arena. Forensic science issues in chemistry and biochemistry in criminal investigations are discussed herein. There are a host of other forensic science areas, eg, forensic medicine, forensic dentistry, forensic anthropology, forensic psychiatry, and forensic engineering, any of which may overlap with forensic chemistry. 

For the first 15 years after the discovery, quasicrystals were studied purely as a compelling scientific issue. Just recently, applications have begun to appear. 

While toner particles were used to exemplify a specific technology and lay the groundwork for discussing the scientific issues surrounding particle adhesion, the topic of particle adhesion extends far beyond copiers. For example, let us consider the fabrication of semiconducting devices. 

One of the main scientific issues of the discovery of the bucky-onions is the unresolved question of minimal energy configuration of carbon clusters (onion-...

The scientific issues associated with understanding and estimating human exposure to chemicals in the environment are vastly more complicated than has been suggested in this chapter, but for present purposes they have been covered sufficiently. The primary purpose of the discussion is to introduce some terms that will come up frequently in later chapters, and to provide some insight into how scientists come to understand how much of which chemicals are present in environmental media, and some of the ways they can come to enter the human body. 

Rather than attempting to expose governmental and corporate ignorance, negligence or corruption, this book explores the underlying scientific issues. It presents a clarification of the scientific basis for our concerns and uncertainties. The Bulletin of Science, Technology and Society... 

There is a family of criteria employed to prioritize investments in collection of genomic sequence data intensively studied organisms, important human pathogens, comparative genomics, ecological and economic impacts, and key basic scientific issues. 

A building owner who decides on abatement is confronted with a variety of technical and scientific issues directly affecting the quality of the job to be undertaken. EPA guidance identifies these... 

The scientific issues indicated earlier are presently addressed in a five-year focussed research program sponsored by ONR. A research roadmap has been formulated with the participation of several U.S. universities, industry, and international research organizations. The scientific research areas addressed and the knowledge (transition elements to technology) expected from this program to help the development community in their PDE efforts are shown in Fig. 30.7. 

CVM is currently engaged in an active review of all available research and other information, particularly that generated since 1977, to assess the impact of this complex scientific issue on the subtherapeutic feeding of antibiotics to animals. 

Over the years, scientific research with human subjects has provided valuable information to help characterize and control risks to public health, but its use has also raised particular ethical concerns for the welfare of the human participants in such research as well as scientific issues related to the role of such research in assessing risks. Society has responded to these concerns by defining general standards for conducting human research. As an example, studies carried out for the authorization of a medical product, have to be conducted in line with the World Medical Association s Declaration of Helsinki, which describes the general ethical principles for medical research involving human subjects (World Medical Association 2004). The Helsinki Declaration was first issued by the World Medical Association in 1964 and has been revised several times since then. 

Its goal is to further the understanding of scientific issues relating to nutrition, food safety, toxicology, risk assessment, and the environment by bringing together scientists from academia, government, and industry.
