It is mainly emphasized that contaminants have a detrimental effect on the living being, but the detrimental effect does not necessarily have a significant toxicological effect, but still can pose a potential threat to the health of the living being.
Thus, the biological effectiveness of an organic contaminant is described in this example as the potential for the detrimental effect of the contaminant on the organism, or to emphasize its potential threat to the health of the organism.

Biological effectiveness is an important indicator for assessing the toxic effects of contaminants. When the biological effectiveness exceeds a certain minimum standard value, the pollutant in the detection area has higher toxic effect and has serious negative influence on the living things, and the environmental condition of the detection area is unfavorable for the living things and the mechanism operation, so that corresponding measures are needed to be taken in time to improve the water environment condition; in contrast, if the bioavailability is lower than the minimum standard value, the toxicity of the pollutants in the detection area is smaller, the threat to the organisms is lower, the bioavailability in the detection area is good, and most organisms can normally survive and absorb the needed nutrition.

The method is characterized in that the average motion inhibition rate of organisms in a water area with serious pollution and poor quality is twice that of clear water, the high-concentration suspension mixture can further inhibit protein synthesis of organisms in water, and the biological physiological condition of a river with little industrial or living pollution source can be maintained at a normal level, so that water environment risk evaluation can be carried out through biological toxicity condition, and water environment quality evaluation is carried out.

The flow degree of the detection area refers to the flow condition and speed of the water body in the detection area, and the flow degree can reflect the flow state of the water body, including but not limited to the speed, direction, fluctuation and the like of the water flow.

And then, based on comprehensive evaluation of the effectiveness index, the biotoxicity index and other related indexes of the daphnia magna, the survival condition and the environmental evaluation data of the daphnia magna can be compared with the water environment management target, whether the water quality condition of the detection area meets the standard is deeply known, if the water environment condition of the detection area does not meet the standard, further investigation of reasons and corresponding water environment protection or improvement measures are needed, and corresponding water environment protection or improvement strategies are formulated based on the effectiveness index, the biotoxicity index and other related indexes, wherein the strategies include but are not limited to measures such as pollutant emission reduction, ecological restoration, water resource management and the like, and the water environment condition can be detected more comprehensively according to the water environment evaluation method in the embodiment, so that scientific basis is provided for protecting and improving the water environment.
Furthermore, in order to better understand the water environment conditions and the water environment quality conditions of different areas, a more targeted measure is provided for water environment protection and improvement, and the water environment evaluation method based on biotoxicity and bioavailability in the embodiment further comprises: analyzing the sediment mixture condition of the detection area according to the biotoxicity condition and the environmental evaluation data; and then evaluating the water environment quality of the detection area according to the sediment mixture condition, the biotoxicity condition and the bioavailability condition.
In an alternative embodiment, the sediment mixture condition of the detection zone is analyzed based on the biotoxicity condition and the environmental assessment data. The condition of the sediment mixture has important influence on water quality and water area ecological system, and according to the prior information, the suspended sediment combined organic matters refer to organic pollutants combined with suspended sediment particles. The organic matters are usually formed by combining organic matters in a water body with suspended sediment particles, so that the combined organic matters are formed, and the forming mechanism of the combined organic matters in actual life also involves physical adsorption, chemical adsorption or biological adsorption and other processes. The presence of suspended sediment in combination with ecological organisms can have negative effects on the water environment and ecosystem including, but not limited to, affecting water quality, affecting the survival and reproduction of aquatic organisms, and the like. Therefore, the method has important significance on the properties, sources and behaviors of suspended sediment combined organic matters for protecting and treating the water environment.
Based on a biotoxicity detection model, the sediment content has a remarkable influence on biotoxicity, and along with the increase of sediment concentration or density, the biotoxicity index in a water area is correspondingly increased, namely, the toxicity influence of suspended sediment combined organic matters on aquatic organisms mainly goes through two processes: firstly, the aquatic organisms ingest suspended sediment, and the suspended sediment can enter the digestive tract of the aquatic organisms and is retained in the aquatic organisms; then, the suspended sediment bound organic matters entering the aquatic organism are desorbed under the action of the digestive juice in the organism, and are absorbed by the organism and generate toxic effects.
In addition, suspended sediment has an enhanced toxicity index for daphnia magna. The suspended sediment can interact with pollutants along with the passage of time, and the suspended sediment can absorb and desorb the pollutants, so that the suspended sediment can carry a large amount of pollutants, and meanwhile, the suspended sediment contacted with the daphnia magna is increased, more toxic substances can be utilized and absorbed by the daphnia magna, and stronger biotoxicity is generated.
Further, the biological toxicity index and the density of suspended sediment are in a proportional relation, the corresponding biological toxicity index can rise along with the increase of the density of the suspended sediment in the detection water area, the suspended sediment plays a key role in the water environment quality, and the influence relation of the sediment content in the water area on the water environment quality can be analyzed based on the biological toxicity index and is used for evaluating the quality condition of the detection water area and predicting the potential ecological risk.
The water environment condition of the detection area can be more comprehensively known by evaluating the water environment quality of the detection area according to the sediment mixture condition, the biotoxicity condition and the bioavailability condition. The biotoxicity test can reflect the potential hazard degree of pollutants in the water area, and the biological effectiveness can reflect the actual influence of the pollutants on the living beings. The factors are combined with the condition of the sediment mixture, so that the quality of the water environment can be judged more accurately, and a more targeted measure is provided for water environment protection.
In addition, the comprehensive evaluation method can also provide important decision basis for comprehensive management and ecological restoration of the water environment of the detection area. By knowing the water environment quality condition, a corresponding water environment protection strategy can be formulated, and the ecological restoration of the environment in the detected water area is promoted. Meanwhile, the evaluation method is also beneficial to improving the awareness of people on water environment protection and promoting the social world to participate in the protection and improvement of the water environment together.
Because most rivers have the characteristic of high sediment content, the water environment quality risk evaluation is carried out on the basis of the sediment mixture condition, the biotoxicity condition and the bioavailability condition, the water environment quality of the detection area is evaluated, the water environment condition can be more comprehensively known, a more reasonable water environment quality standard is formulated, a scientific basis is provided for water environment protection and improvement, and comprehensive management and ecological restoration of the water environment are promoted.
Furthermore, the analysis method for the water environment quality in the embodiment is only an optional condition of the embodiment, and the detection method for the water environment in other or some embodiments can be optimized according to the implementation condition and the actual requirement, so that the water environment quality can be better estimated, and a scientific basis is provided for subsequent water environment protection and improvement.
