1PhD student, Physician, Assistant Professor at the Department of Hygiene and Ecological Medicine, Faculty of Public Health, Medical University – city of Plovdiv, Republic of Bulgaria. The sensible use of water resources and their protection from pollution is not only an environmental issue, but also an important factor for sustainable economic growth.
The territory of the Republic of Bulgaria is divided in four Basin Directorates for Water Management. Disease occurrence is influenced not only by health culture, age, sex, individual lifestyle peculiarities, etc., but also by factors, such as length of service duration, work process characteristics and occupational environment conditions.
Materials and methods: The primary information on instantaneous disease rate was collected from the periodic medical exam records, which was regulated by the Bulgarian legislation [1].
The relative share of hearing disorders among the persons working in the Sewerage sector, distributed by age groups was relatively higher in comparison to the share among those, working at the Water Supply sector, which might not be explained only by means of the age-related changes. Diseases of the musculoskeletal system and connective tissue formed insignificant part from the momentary morbidity rate structure. There were no infectious diseases registered among the employees in both groups, despite the employees in the Sewerage sector were exposed to infectious agents. Discussion: The pilot study of momentary morbidity rate, which was conducted by us in 2012 established a high instantaneous disease rate in both groups of employees, covered by a periodic medical exam, and the tendency for the number of diseases to increase with biological age increase.
The Hearing Center of Excellence fosters and promotes the prevention, diagnosis, mitigation, treatment, rehabilitation and research of hearing loss and auditory injury. Take the challenge, pledge your commitment, and share your story in the prevention of hearing loss in America today. The Hearing Center of Excellence is committed to promoting Hearing Loss Programs and Hearing Loss Prevention Initiatives across the DoD. The second largest one is the East White Sea Region, located in a part of the Central South Bulgaria in 10 administrative counties, 92 municipalities, 1772 settlements and 20 Water Supply and Sewerage companies with 24 urban waste water treatment plants. The length of service at a particular workplace may be a ‘terrain’ on which any latently existing pathological deviations related to particular risk factors of occupation and environment may appear, or new ones may form.
In our opinion, this might be explained by the fact that most infectious diseases had acute onset and as a matter of principle they do not get chronic, due to which employees use a sick-leave with temporary disability and remain unregistered during the periodic medical examinations (instantaneous disease rate). The high Arterial hypertension disease rate could be explained by a great number of factors, as risk production factors might not be ignored, as well.

Other extraaural changes, changes to hearing sensitivity, correlations of hearing and extraaural changes. It supports the development, exchange and adoption of best practices, research, measures of effectiveness and clinical care guidelines to reduce the prevalence and cost of hearing loss and tinnitus among Warriors and Veterans. Take the pledge to implement the Comprehensive Hearing Health Program (CHHP) at your local clinic and share with us how it's going for you! The aim of this study is to analyse the momentary morbidity rate of the employees in one of the biggest companies for drinking water supply and waste water treatment in Bulgaria. Employee health status monitoring is being exercised by means of periodic medical exams, during which the abilities of the employees to fulfil their obligations in the specific industrial environment conditions having in mind their established health status are being assessed. The purpose of this research is to analyse the momentary morbidity rate of the employees in one of the biggest companies for drinking water supply and waste water treatment in Bulgaria.
Data is processed by means of the descriptive statistic and relative share comparison methods.
The total number of registered diseases was larger than the number of employees, because more than one disease has been registered in some of them. For example, work in shifts and night work lead to cardiovascular disease incidence increase. According to many authors the combination of this type of work with chemical factors, noise and vibrations increases the risk of cardiovascular disease development by 40% [2, 3, 4]. Momentary morbidity rate analysis for one year only failed to demonstrate a convincing relation between the exposure to occupational environment factors and the registered diseases. It was found that there is a relation between disease rate increase and biological age increase (Table 4). On the other hand, the registered incidence of this disease corresponded to the official statistics for Bulgaria – arterial hypertension had the highest relative share in comparison to any other diseases among population – 12.8% [5], which demonstrated that production factors were not the only reason. Health-related changes occur after various periods of time (from several months to 5 years) as a result of occupational environment factor impact.
The distribution of the persons that were covered by the periodic medical exam is shown in Tables 1 and 2.
The National Study of Risk Factors related to the Health of the Population aged 25-64 [6] which was conducted in Bulgaria in 2007 established that one of three men and one of four women suffered from the disease. Therefore, in our opinion a momentary morbidity rate analysis for a minimum period of 5 years is necessary. Therefore, in our opinion, the high % of arterial hypertension established was a result of the combined effects of age, employee quality of life and shift work, including night work.


A high relative share of the employees experiencing hearing loss is established, the causal complex of which most probably included the high level of noise in the occupational environment.
The pressure on visual analyser in employees who exercised visual control on the machines in case of insufficient illumination may have aggravating effect on the health status related to the determined high relative share of the Disorders of Refraction and Accommodation.
The analogical eye exams which were conducted on the basis of screening visual tests of employees determined that there were unconvincing data on deviations in young persons’ eyesight [7]. There is no integrated statistical system in Bulgaria to follow-up employee morbidity rate as a whole and by sectors, irrespective of the fact that occupational medicine services are being engaged with this activity.
With the large relative share in both groups are Arterial hypertension, Conductive and sensorineural hearing loss, Disorders of refraction and accommodation, Obesity. Having in mind the fact that some eye diseases occur in young age, before the first employment has begun, their aggravation during work was possible. One example is the astigmatism disease, which is a congenital condition, but falls within the group of the Disorders of Refraction and Accommodation. Practice established that hypermetropia (farsightedness in elderly people) increases with biological age increase.
The exposition to noise at work leads not only to changes to hearing analyser, but also to a number of vegetative disorders of the nervous, endocrine, cardiovascular systems, etc. A high % of the examined employees was found to have Deafness, related to sound conduction disorders (conductive) and sensorineural hearing loss. Technological equipment (mainly electric motors and pumps) in waste water treatment plants generates medium- and high-frequency noise within the range of 125-4000 Hz, with its intensity within the range from 62 dB(А) at control desks up to 98 dB(А) at the pumps of the mechanical sludge removal machines [10]. During the research conducted we did not discuss any relation between hearing loss and occupational conditions due to the lack of preliminary medical information on the employees at the time of their employment at the company.
We have not excluded the possibility hearing loss in some of the employees to have resulted of inflammatory ear diseases in a previous period.
Age, time of exposure, the degree to which the white finger syndrome is expressed, diastolic arterial pressure is related to hearing loss [12].
