  In Part I of this series (Snyder et al., a), the Chemical Scoring and Ranking Assessment Model (SCRAM) was introduced. This system produces scores for chemicals based on their bioaccumulation potential, environmental persistence, and toxicity. In Part II, scoring of the potential for a chemical to persist in the environment and bioaccumulate was described Cited by: The uptake of persistent molecules to levels of high concentrations can have hazardous effects on flora and, through the food chain, on fauna and human health. Xenobiotics not adsorbed by the soil can become mobile and when the molecule is persistent it may be dispersed by water or air through the biosphere, polluting large geographical areas Cited by:

  This paper gives in Chapter 2 an overview on the history of chemical warfare, addresses in Chapter 3 the inventory of chemical weapons, discusses in Chapter 4 the elimination of chemical weapons and possible problems resulting for the environment (CW), reviews in Chapter 5 some non-lethal chemical weapons and chemical weapons which may be on.

Persistence, bioconcentration, and toxicity (PBT) are important hazardous properties of organic chemicals. In PBT assessments, it is desirable that the three criteria P, B, and T are independent. However, this requirement is not fulfilled if an aqueous lethal concentration (LC50) is used as T indicator because LC50 includes both bioconcentration and intrinsic by: Volume 1/Issue 2 31 Learning Objectives cefine addiction, substance abuse, and substance dependence.D cdentify contributing factors for addiction.I c Explain the biological neural pathways that underlie addiction.

There is a growing concern over aquatic contamination because of its harmful effects on biocoenosis structure, biological life including human beings, chemical pesticides with.

Global Contamination Trends of Persistent Organic Chemicals provides comprehensive coverage of spatial and temporal trends of classical and emerging contaminants in aquatic, terrestrial, and marine ecosystems, including the Arctic and Antarctic ecosystems.

Persistent pain is considered a complex biopsychosocial phenomenon whose understanding and management is yet to be improved. More research is needed to determine the common paths that lead to developing persistent pain, to identify the populations most at risk and to develop and evaluate interventions.

The last decades have seen a shift in pain management, from the Cited by: 8. Bioaccumulation is a property that makes POPs highly toxic.

Hydrophobic POPs have high fat solubility, which are responsible for their favourable bioaccumulation and long time persistence [40,90,92].Generally, POPs transport from one creature to another and bio Cited by: Bioaccumulation is a process of accumulation of chemicals in an organism that takes place if the rate of intake exceeds the rate of excretion.

Chemicals are introduced into the organism through exposure to the abiotic environment (soil, water, air) or as dietary intake (trophic transfer).

Rain is called "Acid Rain" only if it has more acid than normal. The main causes of acid rain are gases called sulfur dioxide (SO2) and nitrogen oxides (NOx). Study the causes, effects, along with a few examples and understand the prevention measures.

DDT had been researched and manufactured in St. Louis by the Michigan Chemical Corporation, later purchased by Velsicol Chemical Corporation, and had become an important part of the local economy.

Medical science has begun to control a number of acute virus infections, many by drug treatment and/or immunization, but persistent virus infections are largely uncontrolled. Diseases caused by persistent virus infections include acquired immune deficiency syndrome (AIDS), AIDS-related complexes, chronic hepatitis, subacute sclerosing panencephalitis (chronic measles.

Chemical warfare agents (CWAs) are defined as “any toxic chemical or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action.” 1.

LATEST BOOK - The Bitterest Pills: The Troubling Story of Antipsychotic Drugs Antipsychotic (neuroleptic) drugs have become some of the biggest blockbusters of the early 21st century, increasingly prescribed not just to people with 'schizophrenia' or other severe forms of mental disturbance but for a range of more common psychological complaints.

Chemical and Biological Weapons: Use in Warfare, Impact on Society and Environment. Gert G. Harigel. Introduction. Since the end of World War II there has been a number of treaties dealing with the limitations, reductions, and elimination of so-called weapons of mass destruction and/or their transport systems (generally called delivery systems).

However, as elaborated above, once released, (unexpected) adverse effects by highly persistent chemicals may not only be biological effects, but also be physical or chemical effects.

Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Runoff can carry pesticides into aquatic environments .Chemical warfare agents can be classified according to their persistency, a measure of the length of time that a chemical agent remains effective after dissemination.

Chemical agents are classified as persistent or nonpersistent. Agents classified as nonpersistent lose effectiveness after only a few minutes or hours or even only a few seconds.
