Sediment Testing

Sediments are any particles that can be moved by fluid flow and eventually become a layer of solid particles beneath water or other liquids. Rivers, oceans and lakes all accumulate sediments. Sediment testing is one of the important components of ecological environment monitoring. Sediments have a pollution indicator effect on the environment in the area where they are located. Compared with the testing of other environmental elements, sediment testing only requires smaller samples and lower sampling frequencies, which can reliably reflect the pollution of the environment within a larger spatial and temporal scale, as well as the status and changing trends of regional environment quality.

Sediment testing can carry out component analysis, content testing and physical and chemical index detection of water body sediments, which is an important means of monitoring the ecological environment of water bodies. Professional sediment testing can analyze the content of heavy metals, organic matter and microorganisms in the sediment, and judge the pollution degree of the water body, so as to timely treat the water body and avoid the accumulation of pollutants in the aquatic organisms. Sediment testing is helpful for more effective development, utilization and research of water environment, which is of great significance for maintaining ecological environment and protecting human health.

STEMart provides comprehensive sediment testing services to determine the degree of pollution of water bodies, and provides professional technical support for the monitoring and management of water environments.
