Water is one of the important material resources essential for human survival and development and is the lifeline for economic development and social progress. However, with the increase in the world's population, the rapid development of industrial and agricultural production of water for living and production, some areas of water ecological damage, water environmental pollution, and other issues are prominent. For example, in recent years, eutrophication of water bodies in lakes, rivers, reservoirs and other surface water is becoming more and more serious, affecting and damaging human health has become a prominent problem in the world today.
Lifeasible has therefore established a water nutrient testing, analysis, and assessment platform to provide comprehensive, accurate, and multi-scenario water nutrient analysis services to our clients. Our services cover two areas, including normal water and eutrophic water, and we apply a variety of assessment models covering multiple levels of analysis to provide our clients with only the most accurate analysis results guided by the most professional analysis solutions.
Lifeasible can provide relevant indicators closely related to water eutrophication, such as SD (secchi depth), pH, SAL (salinity), turbidity, TA (total alkalinity), chromaticity, TDS (total dissolved solids), SS (suspended solids), F (fluoride), TN (total nitrogen), TP (total phosphorus), TOC (total organic carbon), NH3-N, NO3ˉ-N, NO2ˉ-N, DO (dissolved oxygen), CODMn (potassium permanganate index), CODCr (chemical oxygen demand), BOD5 (biochemical oxygen demand), Chl-a ( (chlorophyll a), and planktonic algae.
In addition, we also provide correlation analysis of the main control factors of water eutrophication, such as correlation analysis of the mass concentration ratio of nitrogen and phosphorus in water, correlation analysis of Chl-a and nitrogen and phosphorus, etc.
We mainly use the TSI (trophic state index) method to classify the trophic state of the lake from poor to eutrophic as continuous values from 0 to 100, which is a simple and comparable calculation process. The TSI method mainly takes SD, Chl-a, and TP of lake water as indicators, and the magnitude of TSI value corresponds to different trophic states.
The detection indexes are the same as the 21 items in the nutrient analysis of normal water. Our key service in eutrophic water analysis is the establishment of evaluation methods.
At present, Lifeasible for eutrophication water eutrophication evaluation methods mainly include AHP-PCA (analytic hierarchy process- principal component analysis) method, TSIM (modified trophic state index) method, TLI (trophic level index) method, SCO (scoring method), parametric method, biological method, comprehensive water quality identification index evaluation method, fuzzy mathematical operation method, gray clustering method, gray situation decision method and neural network method and other evaluation methods, and has achieved better results in the eutrophication water evaluation.
The study of the water ecological characteristics of different water bodies is an important prerequisite for eutrophication evaluation. Lifeasible selects reasonable evaluation indexes and divides evaluation criteria, and adopts multiple factor discrimination techniques combined with other mathematical methods to scientifically and systematically evaluate the degree of eutrophication of water bodies.

Lifeasible has established a one-stop service platform for plants. In addition to obtaining customized solutions for plant genetic engineering, customers can also conduct follow-up analysis and research on plants through our analysis platform. The analytical services we provide include but are not limited to the following:
