19.How to determine water safety based on the kit’s test data and what is the safety threshold for microcystins in water?
According to the Chinese National Standard GB 5749-2022 Standards for Drinking Water Quality:The safety limit for microcystin-LR(MC-LR)in drinking water sources is 1.0μg/L.The detection limit for both high-performance liquid chromatography(HPLC)and enzyme-linked immunosorbent assay(ELISA)is 0.1μg/L.
Data interpretation and judgment steps:
Calculate the actual toxin concentration by multiplying the measured value with the dilution factor(if the sample was diluted before testing).
Compare the final concentration with the national standard:
<0.1μg/L:Undetected,meeting safety requirements.
≥0.1μg/L and<1.0μg/L:Requires enhanced monitoring and pollution source investigation.
≥1.0μg/L:Exceeds the safety threshold,necessitating immediate emergency measures(e.g.,activated carbon treatment,suspension of water intake).
20.微囊藻毒素检测试剂盒标标准曲线如何理解，如何利用准曲线计算实际测量微囊藻毒素值？
该试剂盒标准曲线为标准样品B0值（每个样品OD值与阴性对照平均值之间的比值）与其对应浓度数值对数之间的关系曲线，因此测得对应OD值后，求出B0值，再利用曲线求出浓度对数（以10为底，浓度的对数），换算出来即可，注意单位（详细步骤，见视频讲解）。
利用标准曲线计算实际浓度的步骤
1.测定OD值：
Measure the OD(optical density)values of all samples(including standards,negatives,and test samples)using a microplate reader at the specified wavelength(e.g.,450 nm).
2.计算B0值：
o计算阴性对照（Negative Control,NC）的平均OD值，记为ODNC-average。
o对于每个标准品或待测样品，其B0值计算公式为：
（本试剂盒无需×100%）
3.查标准曲线或代入回归方程：
o在标准曲线上找到与样品B0值对应的浓度对数值（以10为底，即log10(concentration)）。
o若已知曲线的回归方程如log10(concentration)=a×B0 value+b，代入样品的B0值计算对数值。
4.换算为实际浓度：
o对求得的浓度对数值取反对数（以10为底），得到样品的实际浓度（单位：μg/L）。Concentration=10log10(concentration)
5.稀释倍数校正（如有）：
If the sample was diluted before testing,multiply the calculated concentration by the dilution factor to obtain the final result.
示例说明
已知标准曲线方程：log10(concentration)=−0.02×B0 value+2
测得某样品的B0值：50%
计算过程：log10(concentration)=−0.02×50+2=1⇒Concentration=101=10μg/L
注意事项
曲线线性范围：确保样品的B0值落在标准曲线的线性区间内（通常为标准品浓度范围的50%–150%），超出范围需稀释后重新检测。
单位一致性：标准曲线的浓度单位需与检测目标一致（如μg/L），避免换算错误。
操作规范性：标准曲线需与样品同步检测，避免因试剂批次、温度或仪器差异导致误差（详细操作见试剂盒配套视频讲解）。
20.How to understand the standard curve of the microcystin detection kit and calculate the actual microcystin concentration using the curve?
The standard curve of the kit represents the relationship between the B0 value of standard samples(the ratio of each sample’s OD value to the average OD value of negative controls)and the logarithm of their corresponding concentrations(base 10).This curve is established by plotting known standard concentrations against their respective B0 values,forming a logarithmic regression model to quantify unknown samples.
