In order to implement the "Environmental Protection Law of the People's Republic of China", protect the environment, protect human health, and standardize environmental monitoring, the Ministry of Environmental Protection recently approved four soil testing standards, including the "Electrode Method for Measuring Soil Conductivity". The Electrode Method for Measuring Soil Conductivity (HJ 802-2016) specifies the electrode method for measuring soil conductivity. It is suitable for the determination of the conductivity of air-dried soil. "Determination of 12 metal elements in soil and sediment aqua regia extraction-inductively coupled plasma mass spectrometry" (HJ 803-2016) provides for the determination of cadmium, cobalt, copper, chromium, manganese, Inductively coupled plasma mass spectrometry for a total of 12 metal elements including nickel, lead, zinc, vanadium, arsenic, molybdenum and antimony. "Determination of 8 effective state elements in soil-diethylenetriaminepentaacetic acid leaching-inductively coupled plasma emission spectrometry" (HJ 804-2016) provides for the determination of copper, iron, Inductively coupled plasma emission spectrometry with 8 effective elements in total: manganese, zinc, cadmium, cobalt, nickel, and lead. "Determination of Polycyclic Aromatic Hydrocarbons in Soils and Sediments by Gas Chromatography-Mass Spectrometry" (HJ 805-2016) specifies gas chromatography-mass spectrometry for the determination of 16 polycyclic aromatic hydrocarbons in soils and sediments. It is reported that these standards will be implemented from August 1.
