Therefore, this also requires us to strengthen the sampling quality control in the process of ecological environment quality monitoring. Based on the actual work, we can continuously explore the shortcomings in the process of ecological environment monitoring and sampling, and formulate corresponding solutions, so as to effectively ensure that the sampling quality control in the process of ecological environment monitoring can be implemented, and the environmental monitoring work can contribute to environmental protection.展开更多

In this paper, the quality control of soil organic and inorganic samples preparation is expounded in detail from the aspects of sample preparation site, tools, process, supervision and management, etc., which has strong operability and guidance, and can be used as a reference for soil environmental monitoring workers.展开更多

The results showed that SS concentration in water and natural sedimentation time had the greatest impact on the determination of total phosphorus, while the influence of methods of adding conserving agent, conservation temperature and time was relatively smaller. TP concentration in water samples conserved irregularly was higher than the standard value due to the existence of SS and microorganisms in water, and the deviation became larger with the increase of SS concentration in water. In addition, quality control measures and matters needing attention during the conservation process of water samples were put forward to improve the accuracy of TP concentration.展开更多
