Eco-Toxicity Testing Laboratory


Ecological and Toxicological parameters of chemicals are vital for safe use of chemicals, wastewater treatment and for disposal considerations.

With our Eco-Tox setup, NimkarTek provides a range of ecological and toxicological tests for chemicals and water. These include :

  1. Biological Oxygen Demand (BOD) – as per OECD 301F, APHA 5210B, APHA 5210C, APHA 5210D and IS 3025 (Part 44):1993
  2. Chemical Oxygen Demand (COD) – as per APHA 5220D and IS 3025 (Part 58):1993
  3. Ready Biodegradability – as per OECD 301F
  4. Inherent Biodegradability – as per OECD 302B
  5. Algal Inhibition Toxicity (EC50) – as per OECD 201
  6. Total Dissolved Solids (TDS) and Total Suspended Solids (TSS)
  7. Oil & grease

Algal Growth Inhibition Toxicity :

Algal Growth Inhibition Toxicity is an alternative test to the traditional fish toxicity test (LC50) which is slowly being discouraged due to a ban on Animal Testing.

The purpose of this test is to determine the effects of a substance on the growth rate of unicellular green algal species. NimkarTek is proud to offer this test for all chemical manufacturers who need to test the aquatic toxicity of their chemical. This data can then be entered in the Section 11 of your Safety Data Sheet (SDS)

Water Analysis :

Suppliers are facing increasing pressure to ensure that the water discharged by them is free from hazardous component. Our Eco-Tox centre offers testing of water and waste-water in order to ensure that you are meeting the various regulatory and industry requirements.

  • ZDHC Restricted Chemical Groups in water

  • Total Suspended Solids (TSS)
  • Total Hardness as CaCO3
  • Aluminium
  • pH
  • Chlorides
  • Sulphates
  • Total Alkalinity
  • Turbidity
  • Iron
