Surface contamination results are used to determine the presence of harmful substances, such as bacteria, viruses, chemicals, or radioactive materials, on surfaces. These results help identify potential health risks, assess the need for cleaning and decontamination procedures, and ensure a safe environment for occupants.

What developable surface is used to create the Mercator Projection?
A cylinder is used to create the Mercator Projection. The Earth's surface is projected onto the cylinder, which is then unrolled to create a flat map. This projection results in distortions in the polar regions.
What media is used to look for fecal contamination of a sample?
EMB Agar
Why should the MHA plates be used within a certain time after being made?
MHA plates should be used within a certain time after being made to ensure the agar does not dry out, crack, or lose its effectiveness. Drying out can lead to inconsistent results in microbial growth, affecting the accuracy of the test being performed. Additionally, prolonged storage can also increase the risk of contamination, which can impact the reliability of the results.
What is a Whatch Glass?
A watch glass is a concave-shaped piece of glass used in chemistry labs to cover beakers or evaporating dishes, or as a surface for evaporation or crystallization. It helps prevent contamination and evaporation of the liquid while allowing observation of the contents.
Why you flaming the inoculating tool before and after each inoculation?
M.O are always present,the air, on laboratory surfaces, benches and equipment.they can serve as a source of external contamination and thus interfere with experiment results unless proper aseptic techniques are used during subculturing.
What are the results of detection for surface contamination used to determine?
the need for immediate or operational decontamination
Where can m8 paper be used to detect contamination by liquid nerve or bliser agents?
On any surface where there appears to be liquid chemical agents.
Which is consequence of physical contamination?
Food contamination is usually caused when items laden with harmful bacteria come in contact with the food item. It can be human contact, or contact with the prep table or the surface of utensils used in preparation or cooking.
What are the results for detection for surface conatmination used to be determined?
the need for immediate or operational decontamination
Why do you use a negative control in PCR?
A negative control is used in PCR to ensure that there is no contamination in the reaction, which could lead to false positive results. It contains all the PCR components except the template DNA, so any amplification detected in the negative control would indicate contamination.
Why do we need different toothpicks to mix the blood and serum on slides 1 and 2?
Two toothpicks are used to avoid cross contamination.
What developable surface is used to create the Mercator Projection?
A cylinder is used to create the Mercator Projection. The Earth's surface is projected onto the cylinder, which is then unrolled to create a flat map. This projection results in distortions in the polar regions.
Where can m8 paper be used to detect contamination?
On surfaces
What damage did World War 1 have on the wild life and soroundings?
World War 1 caused water contamination due to the chemical weapons that were used. Deforestation, soil erosion, and wildlife destruction were results of the war.
Is a used knife of food contamination?
Knives that have been used should be washed as they can contaminate other foods.A used knife can cause food contamination. All utensils should be cleaned after each use.
What is the purpose of blank samples?
Blank samples are used to establish a baseline measurement of background contamination in an analysis. By analyzing a blank sample containing no target analytes, researchers can identify and account for any background signals or contamination that may affect the accuracy of their results.
What are disposable gloves used for in the kitchen?
To prevent cross contamination
