Environmental testing

1. Overview

The detection and monitoring of ecological environment is the foundation and important link of environmental protection work. It can accurately, comprehensively and timely reflect the current environment, and provide effective basis for the prediction of environmental development trend, and also lay a foundation for the implementation of environmental protection policies.

The test can provide environmental monitoring, indoor environment detection, public place health inspection, production environment certification test, environmental noise, vibration and radiation detection, soil, sludge and fertilizer detection, solid waste detection, water and wastewater detection, drinking water detection and marine environmental protection related detection, etc. the various monitoring data issued are widely used in environmental impact assessment The environmental protection project completion acceptance, emission permit accounting and the basis for supervision and enforcement play a positive role in environmental management and scientific decision-making.
