Abstract
The quantitative structure-activity relationships between acute toxicity of 88 general pollutants, such as phenols, alcohols, alkanes, alkenes and alkenes, in organic industrial waste to Daphnia magna (24-h IC50) and 8 molecular descriptors are studied by an expert system approach. It shows that the correct classification rate reaches 95% in a training set including 68 compounds, and the correct prediction rate is about 90% in predicting set including 20 compounds. Some rules used in the expert system are interpreted by calculating quantum chemistry parameters, E lumo and E homo.
采用专家系统方法研究了有机工业废水中酚类、醇类、烷烃类、烯烃类等88种常见污染物对大水蚤(24 h IC50)的急性毒性与8种分子描述符的定量构效关系。结果表明,在包含68个化合物的训练集上,正确分类率达到95%,在包含20个化合物的预测集上,正确预测率约为90%。通过计算量子化学参数、E lumo和E homo来解释专家系统中使用的一些规则。
