Biological contamination The contamination of a building environment caused by bacteria, molds and their spores, pollen, viruses, and other biological materials (e.g., animal and human dander insect and arachnid excreta). It is often linked to poorly designed and maintained HVAC systems.he contamination of a building environment caused by bacteria, molds and their spores, pollen, viruses, and other biological materials (e.g., animal and human dander insect and arachnid excreta).

Biological pollution Biological pollution (bioinvasion impacts or biopollution) is a term that defines adverse effects of invasive alien species (IAS) on quality of aquatic and terrestrial environment. Biopollution may cause adverse effects at several levels of biological organization :

What Is Physical Contamination? Chemical contamination is the presence of foreign chemicals in food, bacterial contamination is the presence of harmful bacteria. Although it sometimes happens during preparation, food contamination most often happens during processing. It is sometimes intentional, but the majority of it is accidental.

biological readout biological readout. A term of art referring to the result of a molecular interaction or gene activation—e.g., hair depigmentation as a readout for pharmacologic inhibition of the KIT receptor tyrosine kinase.

Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water. The rising concentration of harmful nutrient compounds – specifically nitrogen and phosphorus – in municipal wastewater treatment plant discharge causes cultural eutrophication (nutrient enrichment due to human activities) in surface waters.

Biosafety Biosafety is the prevention of large-scale loss of biological integrity, focusing both on ecology and human health. These prevention mechanisms include conduction of regular reviews of the biosafety in laboratory settings, as well as strict guidelines to follow. Biosafety is used to protect from harmful incidents.

Medical Definition of Biosafety Medical Definition of Biosafety. Biosafety: The application of knowledge, techniques and equipment to prevent personal, laboratory and environmental exposure to potentially infectious agents or biohazards. Biosafety defines the containment conditions under which infectious agents can be safely manipulated. The objective of containment is to confine biohazards and to reduce the potential exposure of the laboratory worker, persons outside of the laboratory, and the environment to potentially infectious agents.

Biological Hazards A society or community can be seen as vulnerable to biological hazards because of the following: 1  Poor sanitation practices: indiscriminate dumping, polluting of drainage channels and sewers, consumption of contaminated water or food etc.  Hospitals and medical centres dispose of medical wastes improperly.

Radioactive contamination Radioactive contamination, also called radiological contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency - IAEA - definition).

- Food contamination is when something makes the food inedible or can cause illness when consumed. Contamination can be   # Biological (bacteria, parasites, viruses, etc.) …  # Chemical (cleaners, sanitizers, additives, etc.)  # Physical (glass, metal, etc.)   Contamination is not necessarily obvious or visible.ood cross contamination is basically food poisoning. If you cooked 2 different raw things together, your mixing 2 nasty raw things together and cross contaminate. Get it, contamination as like when you mix 2 different things together and cross as in 2 or more things.

What is bioremediation? Remediate means to solve a problem, and bio-remediate means to use biological organisms to solve an environmental problem such as contaminated soil or groundwater. In a non-polluted environment, bacteria, fungi, protists, and other microorganisms are constantly at work breaking down organic matter.

- A definition of the term extrinsic contamination is presented. It refers to the contamination arising from sources other than the raw food itself, namely external sources of contamination, such as foreign bodies.

Biological Warfare Law and Legal Definition The use of biological weapons is prohibited by international law. It is scarcely used in modern times. The first diplomatic effort to limit biological warfare was the Geneva Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare.

Classification and Risk of SSI Contaminated procedures occur when gross contamination is present at the surgical site in the absence of obvious infection. Laparotomy for penetrating injury with intestinal spillage and elective intestinal procedures with gross contamination of the surgical site are examples of contaminated procedures.

Graphical index Biological hazard. Biological hazards, also known as biohazards, refer to biological substances that pose a threat to the health of living organisms, primarily that of humans. This can include medical waste or samples of a microorganism, virus or toxin (from a biological source) that can affect human health.

Biological Hazards in Food For example, the capacity of food-poisoning bacteria to cause large outbreaks of acute illness is an ever-present threat in the food supply chain. It is microorganisms and food-borne parasites that are of most concern as biological food safety hazards. A number of bacterial species are food safety hazards.

Biological Attack Fact Sheet: Human Pathogens, Biotoxins, and Agricultural Threats A biological attack is the intentional release of a pathogen (disease causing agent) or biotoxin (poisonous substance produced by a living organism) against humans, plants, or animals. An attack against people could be used to cause illness, death, fear, societal disruption, and economic damage. An attack on agricultural plants and animals would primarily cause economic damage, loss of confidence in the food supply, and possible loss of life.
