  • Food can be defined as the nutritive material taken into an organism for growth, work, or repair and for maintaining the vital processes. Food sustains life, and, as such, many individuals view food as an uncomplicated, pure source of nutrition. Therefore, such individuals are often bewildered to learn that food is comprised of an array of natural chemicals, and not all the chemicals are nutrients or enhance nutritive value, but in fact may decrease nutritional value or, worse still, are toxic (e.g., naturally occurring toxicants).

  • The international significance of research into the sources, behaviour, fate, and effects of persistent organic pollutants (POPs) is exemplified by the Stockholm Convention for which the host organisation is the United Nations Environment Programme (UNEP). Following extensive negotiation, it was adopted on 22 May 2001, entered into force 90 days after the 50th party had ratified it on 17 May 2004, and by late 2008 there were over 180 participants (http://chm.pops.int/).

  • As for the presentation of beers, two methods are common, each with positive and negative points. One method of presentation permits judges to open and pour the beer into their own cups. A second method of presentation requires stewards to pour beer into pitchers, and the beer is transferred from the pitcher into judges’ cups. When judges are allowed to pour their own beers, there is some danger that moving bottles to the evaluation table will stir up yeast and that judges’ opinions of a beer’s quality will be influenced by the appearance of the bottles that it comes in....

  • Unlike stratospheric ozone that protects life on earth, tropospheric ozone is highly toxic and is the main pollutant of the atmosphere of industrialized countries and cities. Its precursors are emanated from industrial activities and traffic. Generated by lightning, photochemical reactions or with free radicals, it has a density of 1.66 times greater than air and is maintained close to the ground. It decomposes easily, generating free radicals with oxidizing power. The main primary pollutants leading to ozone formation are nitrogen oxides, volatile organic compounds and methane.

  • The media strongly influence people’s conceptions and perceptions of the so- cial environment. While providing entertainment, they also impart information, cul- tural knowledge and values that in turn influence how people come to view themselves, certain social groups, gender roles, etc. Thus, the media not only aid in socialization, but by providing symbolic resources, they also exercise a form of pedagogy.

  • Between 1960 and 2007 the population in the current EU-27 countries expanded from 403 million people to around 495 million people (EUROSTAT 2008a). Factors that influence population change, such as life expectancy, fertility and mortality rates, and net migration are currently undergoing significant change, as are other socio-demographic behaviours such as marriage rates. In addition, the socio-economic status of women is changing. More women are employed and reaching higher levels of educational attainment, which has resulted in greater female autonomy.

  • Integrate social and emotional development into existing programs and services. States can use current systems and funding to expand their capacity to support early childhood social, emotional and behavioral health. States could use Medicaid to promote healthy development through routine developmental screenings and care coordination, utilize Head Start to support parent education, provide training and professional development to early childhood programs and agencies and use federal funds to enhance their state’s capacity.

  • The war in Vietnam finished over 30 years but its wounds have never been healed yet, particularly the effects of the toxic chemical/dioxin sprayed by the U.S. Army. Recently, Vietnamese and foreign scientists have implemented studies in this issue. They have seen that effects of the Agent Orange/Dioxin heavily multi-face influenced on economic-social life, people’s health, and environment. Therefore, the requirements for resolving this issue are comprehensive, huge, urgent and can not be delayed.

  • The first edition of Toxicological Chemistry (1989) was written to bridge the gap between toxicology and chemistry. It defined toxicological chemistry as the science that deals with the chemical nature and reactions of toxic substances, their origins and uses, and the chemical aspects of their exposure, transformation, and elimination by biological systems. It emphasized the chemical formulas, structures, and reactions of toxic substances. The second edition of Toxicological Chemistry (1992) was significantly enlarged and increased in scope compared to the first edition.

  • Introduction: Hydrogen sulfide (H2S) is a colorless gas with the smell of putrid eggs; it can exist in both nonionic and ionic forms in aqueous solution. The ratio of the nonionic form to the total ionized one is influenced by concentration of hydrogen ion in the solution. Under acidic conditions, H2S does not ionized and evaporated from water; under alkaline conditions it is easily ionized and retained in the solution.

  • Currently, adult cells seem to have certain advantages regarding rapid clinical translation. Most biomaterials used in Tissue Engineering are based on acellular matrices or polyglycolic acid. Both materials must provide tissue support until the cells produce their own extracellular matrix. Ideally, they degrade thereafter without any toxic byproducts. Over the last years we started to understand the influence of the biomechanical environment allowing these cell-biomaterial composites to unfold their full functional potential.

  • Surprisingly the toxicity level of fertilizer industry discharge may influence by the environmental factors such as conductivity, temperature, pH, cardon dioxide (CO2), oxygen and elements. Through studies, these factors will influence the behavior and certain biochemical indices of the fish, such as C. striatus, by acting either in synergistic, antagonistic or simple additive manner (Yadav et al., 2005; Bobmanuel et al., 2006; Yadav et al., 2007). A high conductivity value indicates high concentration of dissolved ion within the industrial discharge.
