The Pollution Monitoring Laboratory (PML) has the facilities to analyse pesticide residues, and monitor air pollution and water quality.
bul_org.gif (962 bytes) Pesticide Residues Analysis
PML analyzes the following substances
  • Water -- river, ground and drinking water
  • Soil -- adjoining residential areas and areas in proximity to agricultural field
  • Food commodities - dairy products, including milk, butter, ghee and eggs; crops - cereals, vegetables and fruits, meats -- including mutton, fish and chicken; edible oils, spices packaged, processed and tinned food-bread, infant formula, fruits and vegetables, jam, jelly, juices and dry fruits
  • Human tissues, blood, fat and breast milk
bul_org.gif (962 bytes) Air Pollution Monitoring
PML monitors the ambient air quality, particularly suspended particulate matter, respirable particulate matter , oxides of nitrogen and sulfur. PML also undertakes source monitoring of pollutants from mobile and stationary sources.
bul_org.gif (962 bytes) Water Quality Analysis
PML analyses of physico-chemical parameters of water from sources including river water, ground water, bottled water, among other water sources.

It has a quaternary gradient pump which includes on line vacuum degasser and the manual injector includes on line Rheodyne 7725 i 7- port sample injection valve.
3. UV-VIS SPECTROPHOTOMETER
int_cintra1.jpg (16246 bytes)
A double beam UV-VIS spectrophotometer, Cintra-5 model, which enables fixed point measurement (single wavelength, multi-wavelength, concentration photometric measurement), wavelength scanning and time scanning.
4. Respirable Dust Sampler (RDS)
int_respdustsam.jpg (20831 bytes)
The respirable dust sampler is a stainless steel instrument, which draws the air by the help of high flow rate blower at the nominal flow rate between 1.1 to 1.5 cubic meter per minute. As the air passes through the cyclone inside the RDS, coarse and non-respirable dust is separated from air stream by centrifugal force acting on the solid particles and collects inside the sampling bottle. The size of this type of dust varies from 10 microns to 100 microns. On the other hand fine dust whose diameter is less than 10 microns passes to the filter paper.
