Detection of chlorinated aromatic compounds

[More] Disclosed is a method for making a composition for measuring the concentration of chlorinated aromatic compounds in aqueous fluids and an optical probe for use with said method. The composition comprises a hydrophobic polymer matrix, preferably polyamide, with a fluorescent indicator uniformly dispersed therein. The indicator fluoresces in the presence of the chlorinated aromatic compounds with an intensity dependent on the concentration of these compounds in the fluid of interest, such as 8-amino-2-naphthalene. The probe includes a hollow cylindrical housing that contains the composition in its distal end. The probe admits an aqueous fluid to the probe interior for exposure to the composition. An optical fiber transmits excitation light from a remote source to the composition while the indicator reacts with chlorinated aromatic compounds present in the fluid. The resulting fluorescence light signal is reflected to a second optical fiber that transmits the light to a spectrophotometer for analysis.

Effect of long-lasting use of naphthalane petroleum and its components on the hormonal activity of the adrenal medulla and on the ACT-function of the hypophysis

Naphthalane petroleum (NP) was given in the amount of 100 mg/kg, naphthene paraffins (NPf) in 50 mg/kg and light and heavy aromatic hydrocarbons in amounts of 15 mg/kg daily for 40 days. At certain intervals rats were sacrificed and the relative weight of the adrenals and their content of epinephrine and norepinephrine were determined. In other rats ascorbic acid was determined in the adrenals. NP and NPf, up to 20 days, activated the functions of hypophysis-adrenal medulla, which at 30-40 days returned to the initial condition. Heavy aromatic hydrocarbons, up to 30 days, activated adrenal medulla function, whereas light aromatic hydrocarbons did not affect the hypophysis-adrenal medulla system.
