Toxicological is the adjective that goes with toxicology, the study of poisons. It describes anything belonging to that field: a toxicological report, a toxicological test, toxicological evidence, a toxicological examination. In practice it is almost always attached to work done in a laboratory or presented in court — after a sudden death, someone orders toxicological tests to find out what substances were in the person's body. It is a formal, technical, written word; nobody uses it in ordinary talk.

Be careful not to confuse it with 'toxic'. Toxic describes the poison itself — toxic waste, a toxic gas. Toxicological describes the study of poisons — so toxicological waste would be wrong, but a toxicological study of waste is right.

Be careful not to confuse it with 'toxic'小心不要跟 toxic 搞混. Toxic describes the poison itself toxic 描述的是毒物本身 — toxic waste有毒廢棄物, a toxic gas有毒氣體.
