EFECTOS IRRITANTES EN PIEL, MUCOSAS RESPIRATORIAS Y OCULARES EN TRABAJADORES EXPUESTOS A HUMOS ResumenObjetivo: identificar los posibles factores de riesgo del individuo y ocupacionales asociados a la presencia de efectos irritantes en piel y mucosas de trabajadores expuestos a asfalto en una empresa de infraestructura vial en el 2012. Materiales y métodos: se realizó un estudio de prevalencia analítica mediante la aplicación de cuestionarios de síntomas respiratorios, dermatológicos, autoreporte de síntomas oculares y realización de un examen médico de participación voluntaria a trabajadores expuestos que elaboran y aplican asfalto. Se utilizó la regresión logística en el análisis estadís-tico. Resultados: de 24 trabajadores dedicados a la elaboración de asfalto, 22 (95,8%) presentaron diferentes síntomas irritantes, cinco (20,8%) efectos irritantes de la piel, 12 (50,0%) signos de irritación ocular y 9 (37,5%) efectos en las vías respiratorias bajas. De 111 trabajadores que aplican asfalto, 108 (97,3%) presentaron diferentes síntomas irritantes, 61 (55,0%) efectos irritantes de la piel, 93 (83,8%) presentaron signos oculares, 20 (18,0%) efectos en las vías respiratorias bajas. La antigüedad en el oficio de 5 a 10 años se asoció con la presencia de síntomas oculares, OR=15,9 (IC 95% 1,63-154,53) y con síntomas de irritación en piel (OR= 4,1 (IC 95% 1, 96). La antigüedad en el oficio mayor a 10 años en los trabajadores que elaboran el asfalto y la jornada laboral mayor a 10 horas en trabajadores que aplican el asfalto se asoció a efectos respiratorios (OR=15,0 (IC 95% 1,03-218,3), OR= 15,7 (2,05-120,67 respectivamente) Conclusión: los efectos en salud se presentaron en los trabajadores clasificados en niveles de exposición Alto o Muy Alto y en aquellos con tiempo en el oficio mayor a cinco años, lo que sugiere una probable relación ocupacional entre estos síntomas y niveles de exposición. Se recomendó a la empresa medidas específicas para reducir la exposición y mejorar la vigilancia médica, y una valoración de las concentraciones por exposición a humos de asfalto.

“…5 Studies done in Europe show that bitumen fumes cause respiratory symptoms and increased mortality among road construction workers. 3,6 There is sparse evidence for the adverse pulmonary effects suffered by road construction workers in India, although there are studies on drivers, and other construction workers. This study was aimed at assessing the occurrence of respiratory symptoms, peak expiratory flow rate and oxygen saturation, and awareness and practice of occupational hygiene among road construction workers of Mysore.…”

Background: The process of road formation involves lot of chemicals which harm the respiratory tract. This leads to many health problems faced by road construction workers due to occupation. This study was done to find out the respiratory problems in road construction workers in Mysore.Methods: 128 workers were asked questions about their respiratory symptoms and knowledge of protection from occupational hazards, and their peak expiratory flow rate and oxygen saturation were measured.Results: Only 31.25% workers had appropriate PEFR. The oxygen saturation was more than 95% for all the workers studied. 30% of the workers suffered from cough and 30% from breathlessness. There was poor knowledge and practice of using protective clothing, especially masks (46% and 5%).Conclusions: Policy changes in preventive precautions for occupational hazards need to be brought in.

“…Benzo (a) pyrene [B (a) P] is perhaps the most well studied PAHs and was recently classified as a human carcinogen (IARC, 2009). Many epidemiological studies have shown an increased risk of lung, stomach, nonmelanoma skin cancers, and leukemia in occupational workers with high exposure of PAHs from coal-tar products (Hansen, 1992;Wong et al, 1992;Partanen and Boffetta, 1994).…”

Aim: It is well known that polycyclic aromatic hydrocarbons (PAHs) such as benzo (a) pyrene have carcinogenic properties and may cause many types of cancers in human populations. Genetic susceptibility might be due to variation in genes encoding for carcinogen metabolizing enzymes, such as cytochrome P-450 (CYP450). Our study aimed to investigate the effect of genetic polymorphisms of CYP1A1 (m1 and m2) on genetic damage in 115 coaltar workers exposed to PAHs at their work place. Methods: Genetic polymorphisms of CYP1A1 were determined by the PCR-RFLP method. Comet and buccal micronucleus assays were used to evaluate genetic damage among 115 coal tar workers and 105 control subjects. Results: Both CYP1A1 m1 and CYP1A1 m2 heterozygous and homozygous (wt/mt+mt/mt) variants individually as well as synergistically showed significant association (P<0.05) with genetic damage as measured by tail moment (TM) and buccal micronuclei (BMN) frequencies in control and exposed subjects. Conclusion: In our study we found significant association of CYP1A1 m1 and m2 heterozygous (wt/mt)+homozygous (mt/mt) variants with genetic damage suggesting that these polymorphisms may modulate the effects of PAH exposure in occupational settings.
