During the last decade, entomologists have made progress in understanding the environment in which certain insects live; in particular, we begin to understand the effect of certain physical and chemical factors, which make up a part of the environment. With this gain in knowledge, it is sometimes possible to forecast outbreaks of insects and of diseases conveyed by them, and one can sometimes say that a particular alteration of the environment will result in loss or gain. But so far as mosquitos are concerned, one must admit that though much work has been devoted to the analytical study of the water in which the early stages are passed, the results are disappointing. A consideration of the published work suggests several reasons for this. Investigation into the ecology of the mosquito has had a vogue, and much of it has been done by workers who were isolated and whose knowledge of chemical technique and freshwater biology was limited. Apart from that, the inherent difficulties are great, for the worker must hunt for the limiting chemical and physical factors among a host of others which are doubtless unimportant, and there are few clues to indicate which of the chemical constituents of the water affects the mosquito. The data are therefore voluminous and it is difficult to reduce them to order and present them so that they can be readily understood.

The paper presents characteristics of Debina infiltration intake which provides water for Poznan and neighbouring communes. The evaluation of effectiveness of infiltration process has been done based on the quality parameters of river water and infiltration water. The analysed water quality parameters are as follows: temperature, iron, manganese, DOCKMnO4, TOC, turbidity, colour, dissolved oxygen, free carbon dioxide, conductivity, total hardness, carbonate hardness, pH, heavy metals, detergents and microorganisms. The paper also includes an assessment of the impact of flood conditions on the quality of infiltration water and operation of infiltration intake. In this part of the paper the following parameters were taken into account: iron, manganese, DOCKMnO4, TOC, turbidity, colour, dissolved oxygen, free carbon dioxide, conductivity, total hardness, the total number of microorganisms in 36°C (mesophilic), the total number of microorganisms in 22°C (psychrophilic), coli bacteria, Clostridium perfringens, Escherichia coli, Enterococci. Analysis of the effects of flood on infiltration process leads to the following conclusions: the deterioration of infiltration water quality was due to the deterioration of river water quality, substantial shortening of groundwater passage and partial disappearance of the aeration zone. The observed deterioration of infiltration water quality did not affect the treated water quality, produced at water treatment plant.

The aquatic environment and zoobenthos are closely related in a water body. In recent years, the use of zoobenthos to evaluate water quality is getting more attention as this approach is less polluting and less costly. This study was conducted to assess the diversity of zoobenthos in the canals affected by leachate and agricultural activities. Five sediment samples were collected in two campaigns, one in April and one in October 2018. Water samples were also collected at the same time for zoobenthos to assess the water quality and serve as a reference for assessing the effectiveness of using zoobenthos as water quality indication. In total, 17 species of zoobenthos belonging to six families and four classes were identified, of which Limnodrilus hoffmeisteri and Tendipes species being present regularly at sampling sites through the surveys. The calculations of the Shannon-Wiener diversity index (H'), rapid bioassessment protocol (RBP III), and associated average score per taxon (ASPT) indices based on species composition indicated that the water environment surrounding the landfill was moderately to severely polluted. However, the water quality index (WQI) calculated based on the physical and chemical properties shows that the level of water pollution in canals was less than that evaluated using zoobenthos. This can be explained by the fact that zoobenthos also affected the properties of sediments which depend on the water column. The findings in this study showed that the aquatic environment around the landfill is heavily contaminated as result of waste disposal and agricultural activities. The use of both zoobenthos combined with physical and chemical indicators could be useful in assessing the canals’ water status. Môi trường nước và động vật đáy có liên quan mật thiết với nhau trong một thủy vực. Trong những năm gần đây, việc sử dụng động vật đáy để đánh giá chất lượng môi trường nước mặt được quan tâm vì phương pháp này ít gây ô nhiễm môi trường và ít tốn kém chi phí. Nghiên cứu được tiến hành để đánh giá sự phân bố của động vật đáy trong hệ thống kênh rạch chịu tác động từ nước rỉ rác và các hoạt động sản xuất nông nghiệp. Năm mẫu động vật đáy được thu hai đợt, đợt 1 vào tháng 4 và đợt 2 vào tháng 10 năm 2018. Mẫu nước cũng được thu để đánh giá chất lượng nước và làm cơ sở đánh giá hiệu quả của việc sử dụng động vật đáy làm chỉ thị chất lượng môi trường nước. Kết quả nghiên cứu cho thấy thành phần động vật đáy phát hiện 17 loài thuộc 6 họ và 4 lớp, trong đó các loài Limnodrilus hoffmeisteri và loài Tendipes hiện diện thường xuyên ở tất cả các điểm thu mẫu qua hai đợt khảo sát. Dựa vào thành phần loài tính toán các chỉ số Shannon-Wiener (H’), chỉ số đánh giá nhanh sinh học (RBP III), và chỉ số tính điểm trung bình bình theo họ (ASPT) cho thấy môi trường ô nhiễm rất nặng trong khi đó chỉ số WQI được tính toán dựa vào các chỉ tiêu lý hóa cho thấy mức độ ô nhiễm nước ở kênh xung quanh bãi rác chỉ ở mức nhẹ hơn. Như vậy, việc sử dụng động vật đáy cho kết quả đánh giá chất lượng nước với mức độ ô nhiễm cao hơn. Điều này có thể giải thích là do động vật đáy chịu ảnh hưởng bởi đặc tính nền đáy và cột nước bên trên nền đáy. Kết quả nghiên cứu cho thấy môi trường nước xung quanh bãi rác bị ô nhiễm nặng do xả thải và hoạt động sản xuất nông nghiệp. Việc sử dụng động vật đáy kết hợp với các chỉ tiêu lý, hóa có thể hữu ích hơn trong việc đánh giá hiện trạng nước kênh.

Introduction. The paper presents the hygienic assessment of the complex physical and chemical factors affecting patients and staff in the different premises of institutional medical organizations. Material and methods. The comprehensive hygienic assessment of the internal environment of medical institutions was based on three in-patient medical institutions (IMI). The research objects were medical wards, operating rooms, treatment rooms, dressing rooms, physiotherapy rooms, laboratory and diagnostic rooms, utility rooms. The study included measurements of the following parameters: microclimate, noise, electromagnetic fields level in different frequency ranges, ion regime, assessment of natural light, artificial light, insolation, gamma radiation level, measurements of concentrations of carbon dioxide, oxygen, ozone, radon, mercury vapor, and volatile organic compounds. Results. It is shown that in the hospital environment, a person is affected by complex physical factors. Microclimatic parameters are one of the most significant factors in the hospital environment that require constant monitoring. The control of the given factor is exceptionally substantial in IMI buildings that are not equipped with in-patients an air conditioning system. The highest noise levels were found in physiotherapy rooms and diagnostic rooms. The primary source of noise in medical rooms is working equipment, inwards - conversational speech. Both patients and medical workers were established to receive the main electromagnetic load in diagnostic rooms, laboratory rooms, and physiotherapy rooms. The assessment of the light environment showed that each of the examined rooms was provided with a sufficient level of natural light, and the duration of insolation in the treatment rooms corresponded to hygienic requirements. The highest levels of artificial light were in rooms with led lights. In the air of the examined rooms, light ions of both polarities were either absent, or their content was below the minimum required concentration. Higher concentrations of organic acids and chlorine-containing compounds were found in the surveyed premises of IMO compared to the air in other public buildings. The highest concentration of chemical compounds in the air was observed in wards and diagnostic rooms. Conclusion. The need for regular monitoring of physical and chemical factors affecting patients and staff in IMI is justified. A list of physical factors for carrying out risk-oriented control in hospital premises, taking into account their functional purpose, is required.
