With the acceleration of my country's modernization development process, the environmental problems it faces are becoming more and more severe. Facing the problem of population pressure in our country, water resources are already particularly scarce. In recent years, more and more water pollution problems have seriously restricted my country's development. Development threatens people's lives and safety. Although environmental problems are world problems, many studies have been done, including physical, chemical, biological and other governance methods, which have made good contributions to improving environmental problems, but the governance methods are not The fundamental way to solve environmental problems, how to comprehensively monitor environmental changes, prevent problems before they happen, and enable timely and effective control of environmental problems is the fundamental method to avoid environmental degradation.

At present, traditional environmental monitoring mainly includes physical monitoring and chemical monitoring. Physical monitoring is far behind in terms of cost and monitoring efficiency. With the continuous updating of new chemical substances, chemical monitoring cannot fully meet the requirements of environmental monitoring. Moreover, sampling is difficult, and the effect of timely monitoring cannot be achieved. Biological monitoring is to use the response of biological individuals, populations or communities to environmental pollution or changes to clarify the status of environmental pollution, and to provide a basis for monitoring and evaluating environmental quality from a biological perspective. Biological monitoring can be divided into in-situ passive monitoring and active monitoring. In-situ monitoring uses the natural organisms and communities in the ecosystem to respond to the environment to monitor changes in the environment. It has good sensitivity and can achieve continuous real-time monitoring. monitor. Mussels, clams and snails inhabit freshwater lakes, ditches, ponds and rivers where brackish and fresh water meet, and are widely distributed in inland waters of my country.
