Water Pollution Control Regulation Sampling and Analysis Methods Communiqué Annex-1

The water pollution control regulation, sampling and analysis methods communique published by the Ministry of Environment and Forestry regulates the following principles:

• To determine the quality of the water environment
• Taking water samples continuously or intermittently from wastewater or aquatic environments when discharging domestic and industrial wastewater to wastewater infrastructure facilities or leaving them to receiving environments
• To regulate the rules regarding the measurement and analysis methods of the quality parameters, the control of which is foreseen in accordance with the relevant provisions of the regulation on water pollution control.

The annex to the aforementioned circular includes a table for determining the toxicity dilution factor (TDF) (Annex-1). Essentially, the wastewater content adheres to the fins of fish, causing swelling and rupture of their gills. In this way, the fish are harmed. At the same time, harmful substances absorbed through the fins pass into the fish's bodies , causing poisoning.

The toxic effect of wastewater on fish is expressed by the toxicity dilution factor (ZSF) based on the smallest dilution value that all fish can live. Toxicity dilution factor (ZSF) is the smallest value of dilution experienced by all fish.

In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests carried out in this context, there are also Annex-1 services of the water pollution control regulation sampling and analysis methods communiqué.
