||Determination of Sumilex (Diciklin) in air and biological media

||Sumilex is used to fight grey rot of strawberry, grape, sunflower and other crops; it is toxic to warmblooded animals. It can be determined by drawing air through a filter at a known rate, extracting the filter with diethyl ether, and applying the washed and concentrated extract to silica-gel thin-layer chromatography plates. Worker exposure can be monitored by collecting blood or urine samples, extracting aliquots with ether and proceeding as for the air samples. The plates are developed with hexane-chloroform or hexane-acetone mixtures. Spots are visualised by ultraviolet irradiation followed by treatment with silver-amonia complex, or by diazo coupling. The spots are quantitated by comparison of their areas or densities with standards. The UV-silver method gives maximum sensitivity (0.2µg can be detected). For a 5L air sample, this is equivalent to 0.04mg/m3; for typical biological samples, the lower limit is 0.4µg/mL for blood and 0.02µg/mL for urine. The precision in air sampling is +18.5%. Chlorinated and organophosphorus pesticides do not interfere.
