BLEIN SANCHEZ DE LEON, Antonio  and  ARRUGA LAVINA, María Victoria. Evaluación higiénica previa de acrilamida en aire durante la preparación de gel de poliacrilamida (PAA) en un laboratorio de genética. Med. segur. trab. [online]. 2007, vol.53, n.207, pp.47-52. ISSN 1989-7790.

Aims: To know the approximate level of Acrylamide, carcinogenic type 2, in air, during the preparation of Polyacrylamide-Gel in the laboratory, in order to determine if the occupational hygiene situation is acceptable or not, in order to, if not, to implement immediately preventive measurements, before carring out an hygienical assessment following the UNE-EN 689 standard, with much higher costs.  Methods: After the selection of the gel-preparation stages, where evaporation of Acrylamide takes place, the followed method was PV2004, from NIOSH, for the sample collection and for the analyse.  Results: The detected level of Acrylamide in the weighting stage is 723 % of the TLV-TWAand 145% of the TLV-C. In the stirring stage there was found no Acrylamide.  Conclusions: It is necessary to implement immediately preventive measurements. Some of them are proposed. Once implemented it is recommended to carry out an hygienical assessment according to UNE-EN 689.

Keywords : Laboratory; Occupational hygiene; Carcinogenics; Acrylamide.
