Environmental sampling involves the systematic collection of samples from various environments, such as air, water, soil, or sediments, to analyze their composition and detect pollutants or microorganisms. The process typically includes selecting sampling sites, determining the appropriate sampling methods and tools, and ensuring proper handling and preservation of samples to avoid contamination. Once collected, samples are analyzed using various laboratory techniques to assess environmental quality and identify potential risks to health and ecosystems. The data obtained helps inform policy decisions and environmental management strategies.

How does an air sampling pump work?
An air sampling pump measures contaminants such as biological and environmental present in a sample of air. The sample of air is drawn into a tube which is attached to the pump. The air is vaporized and the particular contaminants presence is measured.
What is wet sampling?
Wet sampling is a method of environmental monitoring that involves collecting samples of liquids or substances in a wet state, such as water, soil moisture, or sediment. This technique is commonly used in environmental studies and pollution monitoring to analyze the presence of contaminants or pollutants in a given area.
What does an environmental service company do?
Environmental Service companies ensure the environment is stable and no harm exists upon the environment. They promote laws regarding the environment. They also send out recycle notifications.
What are the reasons for choosing random sampling method for ones research work and what is random sampling method anyway?
because it is the simplest sampling technique which requires less time and cost.

Q1what is work sampling and what are the advantages nad disadvantages of work sampling over time study?
Work sampling involves recording activities and fixed or random intervals, these activities may or may not be rated.Work sampling is good for measuring things occurring over longer periods like the working week (e.g. contingencies like small/infrequent delays). Time study is good for measuring individual operations and operators to establish standard minute values. Work sampling can also do this and is useful for measuring groups of operators / machines at a time.

What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
What is systematic sampling use for?
In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
