The study was carried out on two groups at working age at Van Chang and Nhat villages of Nam Dinh province from end of 2002 to beginning of 2003. Group 1 included 180 mechanical workers at Van Chang village. Group 2 (control group) included 186 cultivators in Nhat village. Results: The percentage of people having history of respiratory diseases such as sore throat, acute and chronic bronchitis in Van Chang village was higher than those in Nhat village (48% vs. 40%). Respiratory function measure show that the percentage of abnormities of respiratory function were 17.3% in Van Chang village and 6.5% in Nhat village. The histories of working accidents in Van Chang village were 14.4% and in Nhat village were 4.8%. Workers at Van Chang machinery village have higher risk of anomalies of respiratory tract in comparison with people in agricultural villages.

Study on impact of work environment and examination on health status of 117 male workers in workshop of “Mai Dong” Company showed that these workers have to work in the heat stress environment with hazard factor lavels are higher than allowed standard such as noise, dust concentration, toxic gases (CO, SO2, NOx..) Almost workers were suffer from diseases as E.N.T, tooth and face, lung disease, eyes. From study measures are suggested to protect and take of workers.

Cross-sectional study was conducted in 6 handicraft villages, 600 producing households, 1.672 handicraft employees and 135 agricultural employees. The study results showed that: 98.4% of producing households had generated hazardous factors such as noise, heat, dust, micro-organism etc. In food processing village: 83.3% of micro-climate samples and 100% of light samples exceeded the permissible limits. In mechanical villages: 100% of noise sample accessed the permissible limit. In fine arts furniture villages: 91.3% of micro-climate sample, 75% of light sample and 69.5% of dust sample exceeded the permissible limits. In general, almost of handicraft employee had poor knowledge on risk factors at workplaces and their harms. The disease prevalence of handicraft employees was 85.3% that was higher than that of agricultural employee (58,5%). The difference was statistic significant (p=0.0001; RR= 1.46). Handicraft employee liked to have healthcare services at commune’s health station or have health workers at worker place and health insurance.

A study of working environment and health on 600 tunnel construction workers working in Central Region from 2001 to 2003 showed that: the working environment at the construction site was severely polluted with more than 60% of measured experiment samples were higher than the standard level. The deeper the tunnel is, the more severe the pollution is. The temperature, humidity, toxic gases (CO, CO2, and NO2), noise and dust tend to increase. The circulation speed of air, illumination power and level of O2 tend to decrease. The health of workers had a decrease tendency in the three year period. The common diseases are tooth, jaw and face diseases, ear, nose and throat diseases, circulation disease, eye diseases and eye related problems. The rate of work related accident reduced, mortality rate was 0.99%; the main causes leading to accidents at work were rock fall, fall, and mechanical devices; in work related accidents, the rate of soft tissue injury was high

The study aimed to link some factors of working environment to the health status of workers. Participants were 228 workers of the Thai Binh Porcelain Company. It is found that the working environment has been polluted by several factor such as heat radiation, dust and noise, especially in baking oven workshop. The diseases that affected mainly to workers included sore throat (43.86%), trachomatis (17.98%), itchiness (9.21%), joint problems (6.36%), rhinitis (5.26%) and conjunctivitis (3.95%).

A survey on chemical and physical factors was conducted in November 1996. The samples of air, water and dust were analysed at the Institute of Occupational Medicine. Results showed that: the conditions of air ventilation, microclimate, light, noise and air pollution, dust at 7 working places in tunnels of Yaly hydroelectric plant were not compatible with allowed hygienic standards.

Surveyed on 8 plant protective facilities and interviewed 500 agricultural households which used pesticide at 10 communes of 5 districts in Quang Tri province. The amount of used pesticide in agriculture was 12 tons/year, herbicide in which 51,7%; insecticide 48,2%. There were various and abundant types of pesticide supplied by many sources from the state and private sectors. The implementation of toxic safety, storage, utilization and treatment of pesticide waste in the community was limited which influenced on the environment and public health.

Study on the working environment and condition of 350 workers in Cai Lan vegetable oil factory in the last 2 years showed that: the most of levels of the noise, gas at the surveyed places were at allowed threshold, but the temperature at the working places, the speed of wind, the humidity were higher than allowed threshold. The rate of common diseases in these workers was lower than these in other industrial facilities in the same area.
