Water Biotoxicity Testing

In polluted water, various pollutants have different degrees of harm to all organisms in the aquatic ecosystems. Information on the concentration of each component derived from traditional physicochemical analysis methods does not provide a complete picture of the potential effects of mixed contamination in aquatic ecosystems.

As an important complementary tool to physicochemical analysis, biological toxicity evaluation methods play an essential role in the monitoring and evaluating integrated water toxicity. The results of water biotoxicity testing can directly reflect the combined effects of all components in a complex system, including the possible superposition, antagonism, or synergism between components.

Therefore, Lifeasible has established an integrated, comprehensive, and accurate water biological toxicity testing system by using a combination of biological testing and chemical analysis to evaluate the water safety of environmental water and the biological toxicity removal effect of water treatment processes, etc. The application scope includes toxicity testing of drinking water, industrial wastewater, domestic sewage, and other various water samples.

Biotoxicity testing methods

Lifeasible uses a variety of biological toxicity testing methods to evaluate the acute toxicity, chronic toxicity, and endocrine-disrupting properties of water. And the test content also includes general toxicity, immunotoxicity, reproductive and developmental toxicity, as well as carcinogenicity, mutagenicity, teratogenicity, and other aspects.

Different species have different sensitivities in the environment to the same contaminant, and the toxicity test results sometimes vary significantly from the actual situation. Therefore, Lifeasible draws on the enrichment patterns and trophic chains of toxicants in natural water and uses organisms located at different trophic levels and in various categories to perform grouped biological toxicity tests, forming a methodological system for assessing potential aquatic ecological risks and avoiding biased test results caused by the use of a single method.

Biotoxicity evaluation methods

Lifeasible integrated application of a variety of biological toxicity evaluation methods will be able to evaluate different aspects of water toxicity, which can be applied in the sudden pollution of water quality, toxic spill accident, earthquake, and other disasters after the occurrence of the affected areas of drinking water safety, water quality emergency and early warning detection and many other aspects.

• Lifeasible through biological toxicity test results for water toxicity assessment, including the average toxicity (AvTx) method, toxic print (TxPr) method, potential toxicity (pT) method, the most sensitive test (MST) method, effect-dilution average ratio (EDAR) method, and other toxicity classification system can be applied to assess the effectiveness of wastewater treatment processes, wastewater classification and determine the priority control of pollution sources.
• Lifeasible performs water toxicity assessment by incorporating characteristics of the receiving environment, including potential biodegradability, other ecological, biological, or physicochemical parameters in the environment, etc.
• Lifeasible combines wastewater toxicity with toxic loadings and integrates the relationship between industrial wastewater discharge and toxicity, based on various biological toxicity tests and ecotoxicological tests.

Lifeasible conducts efficient and accurate water safety testing, including but not limited to biological toxicity testing, to comprehensively evaluate the toxicological effects of complex systems on water ecosystems.
