Types of Contaminants
These are contaminants that are easily degradable by nature.
What is biodegradable?
Any biological organism that defines a trait or characteristic of the environment.
What is an indicator species?
These types of norms explain the technique to perform an analytical methodology.
What are NMX?
It refers to the duration of the effect of the pollutant.
What is persistence?
This equipment can ionize the sample to analyze its components.
What is mass spectrometry?
These are new contaminants of concern, they might arise from the reaction of two different pollutants.
What are emergent?
They act as an efficient trap of airborne particulates since they are suspended in mid-air.
What are spider webs?
These are Official Mexican Norms, which usually explain pollution limits.
What are NOMS?
These are the two perfect examples of nuisance pollutants.
What are plastics and glasses?
They permit the change of organic signals into decipherable yield flags.
What are biosensors?
These are artificial contaminants that are not commonly found in nature.
What are xenobiotics?
Using both pollution tolerant and pollution sensitive of these green microorganisms would be best for air quality indication.
What are algae?
This is the acronym for the minimal lethal dose to eliminate 50% of the studied subjects.
What is LD50?
Tendency to disperse and dilute.
What is mobility?
These are methods to collect samples from the air in a matrix.
What are adsorption and absorption?
These are contaminants that are difficult to treat.
What are recalcitrant?
These symbiotic microorganisms are especially useful in forestry to assess where conifers should be planted since they are affected by the same sulfur dioxide levels that cause them to decline.
What are lichens?
The escape of any substance capable of causing harm to man or any other living organism in the environment - EPA.
What is pollution?
These pollutants naturally occur and pose little threat at low concentrations.
What are essential pollutants?
This technique separates a mix of samples.
What is chromatography?
Pb, Zn, Cu, and Cd are examples of this type of pollutant.
What are heavy metals?
When you find coliforms in your water sample, you probably have this bacteria species, which is the most studied so far.
What is E.coli?
The ability to satisfy current needs without affecting future generations.
What is sustainable development?
Pollutants become concentrated in tissues and the food-chain.
What is bioaccumulation?
To measure soil contaminants, you need to do this first.
What is solvent extraction?
