Atomic Absorption Spectroscopy (AAS) is often preferred for measuring environmental pollutants because it offers high sensitivity and selectivity for trace metal detection, making it effective for analyzing low concentrations in complex samples. It is particularly advantageous for analyzing specific metals individually, while Inductively Coupled Plasma Emission Spectroscopy (ICP-ES) can measure multiple elements simultaneously but may have lower sensitivity for some trace metals. Additionally, AAS typically requires less sample preparation and can be more cost-effective for specific applications focused on metals.
some one needs to do this cause i asked the question and no one answered feel me?
yes, when it is released in large amounts than the normal natural percentage in air
Asbestos is an environmental problem in some locations because it is a hazardous material that occures naturally near the surface in some areas. Fire fighters working Forrest fires in some of the western National Parks have had to decontaminate their equipment at times because the dust that settled on it contained asbestos fibers. It can also be an environmental problem if removed from buildings and disposed of improperly, because it might become airborn within a community.
Unburnt carbon, often found in the form of soot or particulate matter, is considered a pollutant. It can have detrimental effects on air quality and human health, contributing to respiratory issues and cardiovascular diseases. Additionally, unburnt carbon can impact the environment by affecting climate change and ecosystem health. Therefore, it is classified as a pollutant rather than a nonpollutant.
Newspaper. Its not plastic because plastic is not biodegradable.
Air is heavier than C02, CO2 has a very low boiling point. It is also a pollutant.
Presumably by "COS" you mean Carbonyl Sulfide. US-EPA lists carbonyl sulfide as a "hazardous air pollutant". So presumably emitters of this compound (other than cabbage farmers) are required to self measure, and describe how they are controlling its emission. I find no direct reference to a limit on emissions.
The lemon battery has no real world advantages other than the materials needed to make one are cheap, readily available, and nontoxic, making it quite suitable for a school science demonstration.
Paper is a biodegradable material, but if allowed to accumulate in large quantities in landfills, it can contribute to methane production and leach harmful chemicals into the environment during decomposition, making it a potential pollutant.
Federal and local officials often have different standards by which they measure costs, thus achieving different results.
why do Coastal communities often experience milder winters and cooler summers than further inland
It is an obtuse angle which is greater than 90 but less than 180 degrees
