Delaney Clause
The Food Additives Amendment of 1958 is a 1958 amendment to the United States' Food, Drugs, and Cosmetic Act of 1938. It was a response to concerns about the safety of new food additives. The amendment established an exemption from the "food additive" definition and requirements for substances " generally recognized as safe" by scientific experts in the field, based on long history of use before 1958 or based on scientific studies. New food additives would be subject to testing including by the "Delaney clause". The Delaney clause was a provision in the amendment which said that if a substance were found to cause cancer in man or animal, then it could not be used as a food additive. "Generally recognized as safe" Generally recognized as safe (GRAS) is a Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance require ...

Food And Drugs
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their unique metabolisms, often evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. The majority of the food energy required is supplied by the industrial food industry, which produces food with intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels, which means that the food and agricu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbicide
Herbicides (, ), also commonly known as weedkillers, are substances used to control undesired plants, also known as weeds.EPA. February 201Pesticides Industry. Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page for EPA reports on pesticide use ihere Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include ''persistence'' (also known as ''residual action'': how long the product stays in place and remains active), ''means of uptake'' (whether it is absorbed by above-ground foliage only, through the roots, or by other means), and ''mechanism of action'' (how it works).

Food Quality Protection Act Of 1996
The Food Quality Protection Act (FQPA), or H.R.1627, was passed unanimously by U.S. Congress, Congress in 1996 and was signed into law by U.S. President, President Bill Clinton on August 3, 1996. The FQPA standardized the way the Environmental Protection Agency (EPA) would manage the use of pesticides and amended the Federal Insecticide, Fungicide, and Rodenticide Act and the Federal Food Drug and Cosmetic Act. It mandated a health-based standard for pesticides used in foods, provided special protections for babies and infants, streamlined the approval of safe pesticides, established incentives for the creation of safer pesticides, and required that pesticide registrations remain current. One of the most prominent sections of the act, the specified protections for babies and infants, was the topic of the National Academy of Sciences' 1993 report, ''Pesticides in the Diets of Infants & Children''. The EPA has cited this report as a catalyst for the creation of the FQPA. Backgroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Resources Defense Council
The Natural Resources Defense Council (NRDC) is a United States-based 501(c)(3) non-profit international environmental advocacy group, with its headquarters in New York City and offices in Washington D.C., San Francisco, Los Angeles, Chicago, Bozeman, and Beijing. Founded in 1970, as of 2019, the NRDC had over three million members, with online activities nationwide, and a staff of about 700 lawyers, scientists and other policy experts. History The NRDC was founded in 1970.Robert Gottlieb, ''Forcing the Spring: The Transformation of the American Environmental Movement'' (revised ed.: Island Press, 2005), pp. 193–94. Its establishment was partially an outgrowth of the ''Scenic Hudson Preservation Conference v. Federal Power Commission'', the Storm King case. The case centered on Con Ed's plan to build the world's largest hydroelectric facility at Storm King Mountain. The proposed facility would have pumped vast amounts of water from the Hudson River to a reservoir and released ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with sta ...

De Minimis
''De minimis'' is a Latin expression meaning "pertaining to minimal things", normally in the terms ''de minimis non curat praetor'' ("The praetor does not concern himself with trifles") or ''de minimis non curat lex'' ("The law does not concern itself with trifles"), a legal doctrine by which a court refuses to consider trifling matters. Queen Christina of Sweden (r. 1633–1654) favoured the similar Latin adage, ''aquila non capit muscās'' (the eagle does not catch flies). The legal history of ''de minimis'' dates back to the 15th century. The general term has come to have a variety of specialised meanings in various contexts as shown below, which indicate that beneath a certain low level a quantity is regarded as trivial, and treated commensurately. Examples of application of the ''de minimis'' rule Taxation Under U.S. tax rules, the ''de minimis'' rule governs the treatment of small amounts of market discount. Under the rule, if a bond is purchased with a small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Risk Assessment
Broadly speaking, a risk assessment is the combined effort of: # identifying and analyzing potential (future) events that may negatively impact individuals, assets, and/or the environment (i.e. hazard analysis); and # making judgments "on the tolerability of the risk on the basis of a risk analysis" while considering influencing factors (i.e. risk evaluation). Put in simpler terms, a risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. Need Individual risk assessment Risk assessment are done in individual cases, including patient and physician interactions. Individual judgements or assessments of risk may be affected by psychological, ideological, religious or otherwise subjective factors, which im ...

Diethylstilbestrol
Diethylstilbestrol (DES), also known as stilbestrol or stilboestrol, is a nonsteroidal estrogen medication, which is presently rarely used. In the past, it was widely used for a variety of indications, including pregnancy support for those with a history of recurrent miscarriage, hormone therapy for menopausal symptoms and estrogen deficiency, treatment of prostate cancer and breast cancer, and other uses. By 2007, it was only used in the treatment of prostate cancer and breast cancer. In 2011, Hoover and colleagues reported on adverse health outcomes linked to DES including infertility, miscarriage, ectopic pregnancy, preeclampsia, preterm birth, stillbirth, infant death, menopause prior to age 45, breast cancer, cervical cancer, and vaginal cancer. While most commonly taken by mouth, DES was available for use by other routes as well, for instance, vaginal, topical, and by injection. DES is an estrogen, or an agonist of the estrogen receptors, the biological target ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potency (pharmacology)
In the field of pharmacology, potency is a measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. A highly potent drug (e.g., fentanyl, alprazolam, risperidone, bumetanide, bisoprolol) evokes a given response at low concentrations, while a drug of lower potency ( meperidine, diazepam, ziprasidone, furosemide, metoprolol) evokes the same response only at higher concentrations. Higher potency does not necessarily mean greater effectiveness or more side effects.

Analytical Chemistry
Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation. Then qualitative and quantitative analysis can be performed, often with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health Scare
A health scare can be broadly defined as a social phenomenon whereby the public at large comes to fear some threat to health, based on suppositions which are nearly always not well-founded. In 2009 an ABC News article listed "The Top 10 Health Scares of the Decade": "Some of these threats turned out to be almost nonexistent. Others were arguably overblown. Some caused widespread harm." They listed the following scares: * Swine flu (H1N1) * Bisphenol A (BPA) * Lead paint on toys from China * Trans fats * Bird flu (H5N1) * Severe acute respiratory syndrome (SARS) * Methicillin-resistant ''Staphylococcus aureus'' (MRSA) * Hormone replacement therapy (HRT) * Anthrax * Cell phones.
