AMBIENT AIR SAMPLING - DAVAO CITY.

Pollutants are nothing but any substance that may present in an atmosphere in such a concentration that it may harmful to surrounding, living organism or human being. Sampling and analysis of air pollutants is known as Air quality monitoring and it is major part of environmental monitoring. There are many advanced types of ambient air Sampling methods. we will learn here only which are most commonly used.

Data obtained by is used to take some action to reduce pollutant concentration to acceptable limits by Environmental Consultants. So the most important objective of any air sampling exercise is to obtain a genuine & representative sample. There are both gaseous & particulate pollutants whose concentration is find out in milligram per cubic meter of air.

Particulate sampling is done with help of high volume air sampler, Dust sampler. In these samplers, particles less than 10 micron are taken into consideration. Filter paper being used in that sampler. Difference between weights of filter papers divided by quantity of air passed gives you particulate matter present in air.

Most frequently occurring pollutants in an urban environment are particulate matters (PM10)(PM2.5) and Total Suspended Particulate(TSP), ammonia (NH3), sulfur dioxide (SO2), nitrogen dioxide (NO2).
