In this article we will discuss about the methods and procedures to measure physical, chemical and biological parameters of water quality. Learn about:- 1. Physical Parameter of Water Quality 2. Chemical Water Quality Parameters 3. Biological Parameter. Physical Parameter of Water Quality: The availability of a water supply adequate in terms of both quantity and quality is essential to human [...]
Noise measurements usually fall into one of two categories. The first category consists of sound level measurements usually made of the dBA level. Common measuring instruments are sound level meters and dosimeters. The second category consists of analyses made in support of environmental noise reduction programmes and product design programmes. In addition to measurement of dBA level, these analyses require [...]
A very large number of different analytical techniques are used for atmospheric pollutant analysis. Some of these whose uses are not confined to atmospheric analysis were discussed. A summary of some of the main instrumental techniques for air monitoring is presented in Table 30.2. Analysis of Sulphur Dioxide: The reference method for the analysis of sulphur dioxide is the spectrophotometric [...]
