X90: Assault by unspecified chemical or noxious substance

Assault by an unspecified chemical or noxious substance refers to a group of medical conditions resulting primarily from a deliberate exposure to a harmful substance. The harmful substances involved may vary widely and are typically of a chemical or noxious nature but are not specified. This can encompass a multitude of symptoms depending on the individual case, which makes the identification and treatment very case-specific. Transmission typically occurs through inhalation, skin contact, or ingestion and the damage can affect many systems in the body, particularly the respiratory, circulatory, digestive, and nervous systems. The progression of these conditions can also be diverse, ranging from immediate to delayed effects, and acute to chronic manifestations. It is important to note that the intention behind the exposure is malicious or violent, making it an assault.
