China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

The ecological testing services we provide primarily cover two major aquatic ecosystems: marine and freshwater. Through qualitative and quantitative analysis of the species, quantity, and distribution of aquatic organisms such as phytoplankton, zooplankton, and benthos, combined with monitoring of environmental factors like water quality and sediment, we systematically assess the community structure, biodiversity, and health status of aquatic ecosystems. The aim is to provide scientific basis and data support for water ecological environment management, ecological restoration effectiveness evaluation, and pollution prevention and control.
