In this paper the levels of phenols and hippuric acid in urine and methylhippuric ninety workers at rubber factory in metropolitan Lima (district ATE), who often used as solvents benzene, toluene and xylene was quantified. Quantification of total phenols, and methylhippuric hippuric acid was conducted by UV-visible spectrophotometry and quantifying methylhippuric acid and hippuric acid by the method of reverse phase liquid chromatography with ultraviolet detector respectively. Levels did not exceed the maximum allowable limit of total phenols and hippuric acid in urine and methylhippuric were found. In quantification of total phenols in urine the average was 42.73 mg / g creatinine and quantification of hippuric acid and methylhippuric acid in urine in the same sample had an average of 0.75 g / g creatinine and 0.45 g / g creatinine respectively. These values are indicative of exposure to both benzene and toluene or other aromatic organic solvents as urine reference values are 50 mg / g creatinine for total phenols as a biological indicator of benzene and 1.6 g / g and creatinine 1.5 g / g creatinine for hippuric and methylhippuric as biological indicators of Toluene and Xylene acid respectively ACGIH (American Conference of Governmental Industrial Hygienists.) the toxicological analyzes were performed in the area of toxicology (LABTOX) Blufstein clinical laboratory. Keywords: Benzene, toluene, xylene, total phenol, hippuric acid, methylhippuric acid, UV-vis, spectrophotometry, HPLC
