  <class>SmallMolecule</class>
  <description>1-Chloro-4-nitrobenzene belongs to the nitrobenzenes, a subclass of benzene and substituted derivatives within the organic compounds. This benzenoid compound has the chemical formula C6H4ClNO2 and an average molecular weight of 157.55 g/mol. In industrial applications, it is used in the production of Polyethylene Terephthalate plastics.

The compound is found in or released from 29 recorded sources across multiple sectors. Within the aquatic systems and sediments category, it is present in groundwater, seawater, freshwater, and surface water. It is also detected in drinking water and water supply sources, including tap water, bottled water, desalinated water, and drinking water. In the sector of wastewater, sanitation, and biosolids, it is found in mine wastewater, industrial wastewater, wastewater treatment effluent, and unspecified wastewater. Additional sources include appliances, HVAC, and refrigerants, specifically water heaters and water coolers. It is associated with food, food processing, and cookware through food preservation, processing fish, and fermentation processes for beer. Furthermore, it is released from electrical and electronic equipment, including electrodes, fixed capacitors and their manufacture, hybrid capacitors, antennas, and conductors or conductive bodies characterised by the conductive materials. Five more sectors are recorded as sources. Human exposure to 1-chloro-4-nitrobenzene occurs through oral, inhalation, and touch routes.</description>
