Aquatic organism base value detection method

Abstract

The invention relates to an aquatic organism base value deriving method. The method comprises the following steps: selecting a species, screening toxicity data, calculating the cumulative probability, acquiring a base value, and carrying out nonlocal species utilization and later sample adding when the toxic data of the species is insufficient. The method effectively solves the non-randomness problem of the toxicity data, and also solves the problem brought by scarcity of the toxicity data of the local species in China.

Description

technical field [0001] The invention belongs to the technical field of water quality protection, and in particular relates to a method for deriving a reference value of aquatic organisms based on statistical extrapolation. Background technique [0002] The Aquatic Biological Baseline is an important tool for water environment management. It aims to protect aquatic organisms and maintain the balance of water ecosystems. It is the scientific basis for formulating relevant water quality standards, and it is also an important basis and criterion for water ecological risk assessment. The acquisition of aquatic biological benchmarks depends on the derivation methodology of aquatic biological benchmarks. At present, the most commonly used baseline derivation method is the statistical extrapolation method, which can be described as inferring the sensitivity of all aquatic organisms in the entire ecosystem through sampling the sensitivity of organisms to pollutants. [0003] The st...

Problems solved by technology

In general, current statistical extrapolation solutions may be effective in some cases, but they cannot be statistically guaranteed to be unbiased, nor can they estimate the severity of errors
