Benzol  ·  Benzole  ·  Cyclohexatriene
Benzene is an important organic chemical compound with the chemical formula C6H6. The benzene molecule is composed of six carbon atoms joined in a ring with one hydrogen atom attached to each. As it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.
Clofenotane (50-29-3)  
DDT  ·  chlorophenothane  ·  4,4' Dichlorodiphenyltrichloroethane
Dichlorodiphenyltrichloroethane (DDT) is a colorless, tasteless, and almost odorless crystalline organochlorine known for its insecticidal properties and environmental impacts. First synthesized in 1874, DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Müller in 1939. DDT was used in the second half of World War II to control malaria and typhus among civilians and troops.
Dipentene (7705-14-8, 9003-73-0, 8008-56-8, 65996-98-7, 8008-57-9, 138-86-3, 8028-38-4, 0008008-57-9)  
limonene  ·  (+)-limonene  ·  limonene, (S)-isomer
Limonene is a clear, colorless liquid hydrocarbon classified as a cyclic monoterpene, and is the major component in oil of citrus fruit peels. The D-isomer occurring more commonly in nature as the fragrance of oranges is a flavoring agent in food manufacturing. It is also used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products.
Atrazine (1912-24-9)  
Atrazine is an herbicide of the triazine class. Atrazine is used to prevent pre- and postemergence broadleaf weeds in crops such as maize (corn) and sugarcane and on turf, such as golf courses and residential lawns. It is one of the most widely used herbicides in US and Australian agriculture.
paroxetine (61869-08-7, 110429-35-1)  
Paroxetine, also known by the trade names Paxil among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is used to treat major depressive disorder, obsessive-compulsive disorder, social anxiety disorder, panic disorder, posttraumatic stress disorder, generalized anxiety disorder and premenstrual dysphoric disorder. It has also been used in the treatment of hot flashes and night sweats associated with menopause.
fenvalerate (51630-58-1, 66267-77-4, 67614-33-9, 67614-32-8)  
esfenvalerate  ·  Pydrin  ·  pydrin, (R-(R*,R*))-isomer
Fenvalerate is an insecticide. It is a mixture of four optical isomers which have different insecticidal activities. The 2-S alpha (or SS) configuration, known as esfenvalerate, is the most insecticidally active isomer.
PhIP (105650-23-5)  
PhIP (2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine) is one of the most abundant heterocyclic amines (HCAs) in cooked meat. PhIP is formed at high temperatures from the reaction between creatine or creatinine (found in muscle meats), amino acids, and sugar. PhIP formation increases with the temperature and duration of cooking and also depends on the method of cooking and the variety of meat being cooked.
