Recently, a group of 5 people from Hunan Environmental Monitoring Center Station came to Yongxing County to carry out one-to-one environmental monitoring technology guidance training activities. The provincial station and the delegation carefully inspected the laboratory of Yongxing environmental monitoring station, and understood the environmental conditions, instrument and equipment configuration, internal quality management, original record filling specifications, etc. of the laboratory in detail. They answered one by one the problems and puzzles often encountered by the monitoring personnel in the actual work, conducted one-to-one guidance and demonstration of key training contents such as ICP-MS, atomic fluorescence, atomic absorption, ion chromatography, spectroscopic colorimetry, and corrected some non-standard operations.

The focus of this monitoring technical training was the errors and puzzles in the practical operation of monitoring work, involving pH, fluoride, dissolved oxygen, permanganate index, chemical oxygen demand, five-day life oxygen demand, ammonia nitrogen, total phosphorus, total nitrogen, cyanide, hexavalent chromium, volatile phenol, petroleum, anionic surfactant, sulfide, fecal coliform, sulfate, chloride nitrate, copper, zinc, lead, cadmium, iron, manganese, arsenic, mercury, selenium, etc. Through on-site operation, face-to-face and hand-held guidance, provincial station personnel tirelessly taught correct operation methods and unique theories.
