The eyes are exposed to many factors, that contribute to the deterioration of their condition. These include environmental conditions and the influence of reactive oxygen species ROS and oxidative stress. Research shows, that one of the most important tasks of created in such way state of emergency is maintenance of relative balance between oxidants (contributing to the formation of ROS) and antioxidants (restraining their effect). Some chemical elements, especially copper, play a key role in blocking ROS and presents an overview of information on the impact of oxidative stress on the eyes and the defense mechanisms with the participation of copper.
眼睛受到许多因素的影响,导致眼睛的状况恶化。这些包括环境条件和活性氧ROS和氧化应激的影响。研究表明,在这种紧急状态下,最重要的任务之一是维持氧化剂(促进ROS的形成)和抗氧化剂(抑制其作用)之间的相对平衡。一些化学元素,特别是铜,在阻断ROS中起着关键作用,本文综述了氧化应激对眼睛的影响以及铜参与的防御机制。

Biodeterioration of construction materials is an undesired phenomenon, generating high costs of constraction repairs. On the other hand, occurrence of some bacteria can affect prevention and self repair of fractures formed in concrete. Biodeposition is an effective solution for increasing compressive strength of concrete, extending durability of concrete constructions and renovating limestone elements in facades of historic buildings.

This article presents a method of use of measurements based on airborne laser scanning to monitoring secondary influences caused by underground exploitation of coal deposits. The issue of secondary influences is still current topic in underground mining, especially in areas with a long mining history. The article presents, on the example of mining exploitation in the city of Bytom, the method of acquiring and processing data from the measurement of airborne laser scanning and interpretation of the obtained results.

The article presents the possibilities of applying the methodology of modeling the spread of pollutants in the air from open burning of waste using the Gaussian Model of I generation, in the case of modifying the assumptions for the input data, in terms of emission heights and meteorological parameters adopted for modeling. The model was adapted to the assumptions of the SCM model (Source Characterization Model). The publication indicates the suitability of using the described methodology in determinated conditions to forecast the spread of the pollution cloud.

The paper presents long-term changes in water levels of Prosna, one of the main rivers in Wielkopolska, i.e. the region which is widely regarded as one of the least abundant in water in Poland. It was established that during the last 40 years the average annual water levels of Prosny showed a downward trend at the level of 7.8 cm-dec-1 and were statistically significant at the level of p=0.05 and also p=0.01. In all months a decrease in the water level was noted, although it was statistically significant in seven cases. The highest decrease in average monthly water levels (statistically significant, p=0.05) occurred in August and December and progressed at a rate of 13.2 and 12.3 cm-dec-1. The consequence of the ongoing trend may be, among others, worsening of ichthyofauna living conditions or worse quality of Prosny's water.
本文介绍了普罗斯纳水位的长期变化,普罗斯纳是Wielkopolska的主要河流之一,即被广泛认为是波兰水资源最不丰富的地区之一。结果表明,近40 a来普罗斯尼年均水位在7.8 cm-dec-1水平呈下降趋势,在p=0.05和p=0.01水平上均有显著的统计学意义。所有月份都注意到水位下降,尽管在7个情况下具有统计意义。月平均水位下降幅度最大的是8月和12月(p=0.05),下降幅度分别为13.2 cm-dec-1和12.3 cm-dec-1。这一持续趋势的后果可能是,除其他外,鱼类生存条件的恶化或普罗斯尼水质的恶化。

RECONSTRUCTION OF NON-EXISTENT BATHYMETRY LAKES KROKOWO 重建不存在的测深湖泊
Pub Date : 2018-10-15 DOI: 10.5604/01.3001.0012.8356
M. Ptak
Intensive land reclamation works carried out a few centuries ago in Poland contributed to a significant impoverishment of the hydrographic network. Currently, more and more often there are problems related to water deficit and implementation of a programme aimed at expansion of retention, e.g. through the construction of artificial reservoirs or damming of natural jellies. In this work, the morphometry of the non-existent Krokowo Lake was reconstructed. It was established that as a result of the anthropopressure impact, the body of water of the area 58.0 ha and capacity of 2.6 millions m3 disappeared. In the light of the increased retention capacity in Poland, the restoration of natural lakes seems to be an interesting approach. Renaturalisation of these environmental elements in the context of improving the water balance components seems more justified than the creation of new (artificial) components.
几个世纪前在波兰进行的密集土地复垦工程造成了水文网络的严重贫瘠。目前,越来越多的问题与缺水和旨在扩大蓄水的方案的执行有关,例如通过建造人工水库或用天然水母筑坝。在这项工作中,重建了不存在的Krokowo湖的形态。结果表明,受人为压力影响,该流域共消失水体面积58.0公顷,容量260万m3。鉴于波兰蓄水能力的增加,恢复天然湖泊似乎是一个有趣的办法。在改善水平衡成分的背景下,这些环境元素的再自然化似乎比创造新的(人工)成分更合理。

This article contains the results of investigations conducted at the WULS in Warsaw concerning initial treatment of sewage sludge by means of microwave disintegration. Sewage sludge were taken from the "Mokre Łąki" wastewater treatment plant in the municipality of Izabelin. Experiments were carried out on concentrated and non-concentrated sludge. Each of the sludges was disintegrated in portions of varying volumes and also at different time of microwave interactions. Significant changes in the values of the tested parameters such as COD, turbidity and temperature due to the sludge suppression process were considered. These parameters have a significant impact on the course of further processes that treated sludge and supernatant liquid can be processed. Therefore, determining the volatility of these parameters is important.
这篇文章包含了在华沙WULS进行的关于用微波分解方法对污水污泥进行初步处理的调查结果。污水污泥取自伊萨贝林市的“Mokre Łąki”污水处理厂。对浓缩污泥和非浓缩污泥进行了试验。每一种污泥在不同体积和不同时间的微波作用下被分解。考虑了污泥抑制过程对COD、浊度、温度等试验参数值的影响。这些参数对处理后的污泥和上清液的进一步处理过程有重大影响。因此,确定这些参数的波动性是很重要的。

The paper presents the overview and characteristics of three different methods of organic compounds determination in wastewater: method according to ATV, respirometric method and method with use of particle separation. The results of laboratory analysis of municipal wastewater composition carried out using each of the described methods are presented. Wastewater derived from sewage collector in Grodzisk Wlkp. The research was performed in 7 series, from October 2013 to May 2014. The results obtained using different methods were compared by statistical tests. The observed differences were the consequence of the contractually assumed coefficients and size of particles and the defects during manual particles separation.

PRELIMINARY STUDIES ON THE INFLUENCE OF NEGATIVE PRESSURE ON ACTIVATED SLUDGE FLOCS 负压对活性污泥絮凝体影响的初步研究
Pub Date : 2018-07-02 DOI: 10.5604/01.3001.0012.7462
A. Gnida, D. Witecy
A sludge from municipal wastewater plant operated for biological contaminant removal was exposed to three different negative pressures (-200, -500 and -800 hPa) for three different duration times (30 second, 1 and 2 minutes). Sludge volume index, shear sensitivity of the sludge and activated sludge floc characteristic was the object of the study before and after negative pressure treatment. After the treatment the sludge settled better independently on the pressure value and duration time. The shear sensitivity changed the most when the pressure exposure of -800 hPa was 1 minute and longer. The flocs structure was more open after negative pressur and larger part of activated sludge was comprised by large flocs.
将一种用于去除生物污染物的城市污水处理厂的污泥暴露在三种不同的负压(-200、-500和-800 hPa)下,持续时间分别为30秒、1分钟和2分钟。以负压处理前后污泥体积指数、污泥剪切敏感性及活性污泥絮体特性为研究对象。处理后污泥沉降较好与压力值和持续时间有关。当-800 hPa压力暴露1分钟及以上时,剪切敏感性变化最大。负压后絮凝体结构更加开放,活性污泥中较大比例由大絮凝体组成。
