Opis:: The environmental risk classification of the metal relics is usually determined by the corrosion rate of the metal but it is difficult to monitor the deterioration of the metal relics directly. A strong relationship exists between indoor exposure, the air quality classification of atmospheric corrosion, and the actual deterioration of metal relics. The copper-silver hanging plate method requires a long period of environmental exposure and has certain hysteresis, thus reflecting the current environmental quality of the museum in real time poses some difficulties. However, the application of the environmental reactivity monitor (ERMs) based on the piezoelectric effect can solve the above problems. The invented quartz crystal microbalance (QCM) reactivity monitoring device is applied to study the influence of temperature and humidity on the corrosion of the bronze-simulated materials and the relationship between the corrosion depth rate of the bronze-simulated materials and the frequency change of the crystal oscillator. Then, the recommended classification range of temperature and humidity and the airquality classification standards for the preservation environment of the bronze cultural relics in museums are proposed.

Opis:: Objectives: The main objective of the study was to determine the levels of house dust mite (Der p1), dog (Can f1), cat (Fel d1) and cockroach (Bla g2) allergens in kindergartens localized in an urban agglomeration. Material and Methods: A quantitative analysis of allergens was carried out in settled dust samples collected by vacuuming the floor surface in three kindergartens (N = 84) and children's clothing (N = 36). The samples were collected in springsummer and autumn-winter periods as well as at the beginning and end of the week. The allergen dust concentration was determined by enzyme-linked immunoenzymatic assay (ELISA). Results: The mean geometric concentrations (±geometric standard deviations) of allergens Der p1, Can f1, Fel d1 and Bla g2 determined in kindergartens were: 0.02±3.21 μg/g of dust; 0.97±4.49 μg/g of dust; 0.30±4.43 μg/g of dust and 0.01±3.08 μg/g of dust, respectively. Younger classrooms (children aged from 3 to 4 years) were characterized by almost twice higher mean concentration of allergen Fel d1, as compared to older classrooms (children aged from 5 to 6 years) (p < 0.05). A significant impact of seasonality on the level of dog allergen Can f1 was found (p < 0.05). No significant weekly variation was found in average concentrations of the allergens. Children who had a dog and/or cat at home were characterized by high concentrations of allergens Can f1 and Fel d1 on their clothes (59.2±5.39 μg Can f1/g of dust; 3.63±1.47 μg Fel d1/g of dust), significantly higher than concentrations of allergens in children who did not have any pets (p < 0.001). Conclusions: Special attention should be paid to keeping the kindergarten rooms tidy and clean and to an appropriate choice of furnishings and fittings which would prevent the proliferation of the house dust mite and accumulation of allergens.

Opis:: Objectives To investigate the effect of CO₂ during sleep on next-morning cognitive performance in young schoolchildren, the authors performed a double-blind fully balanced crossover placebo-controlled study. Material and Methods The authors included 36 children aged 10–12 years in the climate chamber. The children slept at 21°C in 6 groups each at 3 different conditions separated by 7 days in a random order. Conditions were as follows: high ventilation with CO₂ at 700 ppm, high ventilation with added pure CO₂ at 2000–3000 ppm, and reduced ventilation with CO₂ at 2–3000 ppm and bioeffluents. Children were subjected to a digital cognitive test battery (CANTAB) in the evening prior to sleep and on the next morning after breakfast. Sleep quality was monitored with wrist actigraphs. Results There were no significant exposure effects on cognitive performance. Sleep efficiency was significantly lower at high ventilation with CO₂ at 700 ppm which is considered to be a chance effect. No other effects were seen, and no relation between air quality during sleep and next-morning cognitive performance was observed in the children emitting an estimated 10 l CO₂ /h per child. Conclusions No effect of CO₂ during sleep was found on next day cognition. The children were awakened in the morning, and spent from 45–70 min in well-ventilated rooms before they were tested. Hence, it cannot be precluded that the children have benefitted from the good indoor air quality conditions before and during the testing period. The slightly better sleep efficiency during high CO₂ concentrations might be a chance finding. Hence, replication is needed in actual bedrooms controlling for other external factors before any generalizations can be made.

Opis:: Objectives This paper reports on the results of the study aimed at application of ergosterol as an quantitative indicator of fungal bioaerosol present in the indoor air in occupational environment heavily contaminated with organic dust as well as its comparison with the culturable method. Material and Methods The study was conducted in the indoor solid waste sorting plant. Using Andersen impactor adapted to 1 plate at the flow rate of 30 l/min, indoor air was sampled in the workers’ breathing zone. Ergosterol was sampled using gelatinous filter (1000 l of air) and then analyzed by means of the spectrophotometric method. Fungi were sampled on malt extract agar (MEA) medium (3 replications: 2 l, 7.5 l, 15 l of air) and analyzed by means of the culturable method. Based on ergosterol analyzes, concentration of fungi was calculated. Results were given as the range assuming min. as 5.1 pg ergosterol/spore and max as 1.7 pg ergosterol/spore. Results The average concentrations of ergosterol in a working room (arithmetic mean (AM), standard deviation (SD); minimum–maximum (min.–max)) were, respectively: 2.16, 0.72; 0.85–2.92 μg/m³; fungi calculated based on ergosterol – 424.1×10³–1272.4×10³, 140.1×10³– 420.4×10³, 167×10³–1716.5×10³ CFU/m³, and culturable fungi – 13×10³, 9.7×10³, 1.9×10³–34×10³ CFU/m³). It was revealed that concentrations of calculated fungi were even 2 orders of magnitude higher than culturable fungi. Conclusions The quantitative assessment of moldiness by means of ergosterol measurement seems to be a reliable indicator for environments heavily contaminated with organic dust, where viable and non-viable fungi are present in high proportions. Based on that result, more restrictive (as compared to a similar assessment carried out by means of the culturable method) hygienic recommendations, especially those related to the use of preventive measures protecting the employees’ respiratory tract, should have been undertaken.

Opis:: Due to its extraordinary hardness, decorative appearance and possible small dimensions, black locust wood is assumed to be an excellent material for strip parquetflooring. The favourable colour changes achieved by controlled steam treatment further increased the utilization potential of this material. Flooring was installed on a student dormitory stair landing in heavy use. Due to the flooring’s very high exposure, 5 years was considered a long enough period to compare the different face layer materials during in-service test. Oil was used as a coating to avoid the remarkable protecting effect of hard film-forming varnishes (acrylic, etc.) against abrasion. Besides the flooring turning grey (all face layers no matter what treatment), only some delamination occurred at certain places after five years in service.The laboratory test results for abrasion resistance, dimensional changes and deformation were analysed. Additionally, the Brinell-Mörath hardness after indoor service and the abrasion due to indoor service were analysed. In terms of abrasion resistance, dimensional changes and deformation, no essential differences werefound between the oil-treated and untreated black locust wood on the one hand, and the control oak specimen on the other. Long-term tests showed that, after 5 years in service, the Brinell-Mörath-hardness decreased considerably for all the testedmaterials. The type of section and the presence of wide rays influenced the roughness and the waviness of the surface after indoor service.

Opis:: An electronically-controlled sampling system, characterised by its organ pipe design, has been developed for sampling air sequentially, at different heights within the breathing zone. Data are automatically logged at the different receptor levels, for the determination of the average vertical concentration profile of gaseous pollutants. The system has been coupled to a carbon dioxide monitor and used in a brief study of the spatial and temporal variation of indoor carbon dioxide concentration. The system can easily be extended for different heights or modified for use with other types of gas monitor. The results of a trial run, which was carried out in a coffee room, are presented and applications of the Organ Pipe Sequential Sampling (OPSS) system are discussed.

Opis:: The fungi Trichoderma harzianum, T. polysporum, T. viride, Paeciliomyces fumosoroseus, P. lilacinus, Verticillium/lecanicillium lecanii, Ulocladium oudemansii, U. atrum and Beauveria bassiana are used or considered to be used for biocontrol of pests and plant diseases. Human exposure to these fungi in environments where they may naturally occur or are used as biocontrol agents has not been directly investigated to date. This review aims to provide an overview of the current knowledge of human exposure to fungi from the relevant genera. The subject of fungal taxonomy due to the rapid development of this issue is also discussed. B. bassiana, V. lecanii, T. harzianum, T. polysporum, P. lilacinus and U. oudemansii were infrequently present in the air and thus people in general seem to be seldom exposed to these fungi. However, when V. lecanii was present, high concentrations were measured. Fungi from the genera Trichoderma, Paecilomyces and Ulocladium were rarely identifi ed to the species level and sometimes high concentrations were reported. T. viride and U. atrum were detected frequently in different environments and sometimes with a high frequency of presence in samples. Thus, people seem to be frequently exposed to these fungi. Sequence data have led to recent revisions of fungal taxonomy, and in future studies it is important to specify the taxonomy used for identifi cation, thus making comparisons possible.

Opis:: Simultaneous measurements of the indoor and outdoor particle mass (PM) and particle number (PN) concentrations as well as the air temperature, relative humidity (RH), and CO₂ concentrations have been conducted in 6 occupied (L) and unoccupied (V) classrooms in 3 secondary schools in Lublin, Poland, in the heating (H) and summer (S) seasons. The schools were located in residential areas where the majority of private houses are heated by means of coal-burning stoves. The ratios of the average particle concentrations in occupied and unoccupied classrooms (L/V) were higher during the heating season measurements. The ratios of the average particle concentrations during the measurements in the heating and summer seasons (H/S) were higher in occupied classrooms. In both seasons the average PM and PN concentrations amounted to 239 μg/m³ and 7.4×10³/cm³in the occupied classrooms, and to 76 μg/m³ and 5.4×10³cm³ in the unoccupied classrooms, respectively. The particle exposures experienced by students were higher in the monitored classrooms than outdoors and were on average about 50% higher in the heating than in the summer season. A positive correlation between mass concentrations of coarse particles and indoor air temperature, RH and CO₂ concentrations in both seasons was observed. The concentrations of fine particles were negatively correlated with the indoor air parameters in the heating season, and positively correlated in the summer season.
Pomiary masowych (PM) i ilościowych (PN) koncentracji cząstek, jak również temperatury, wilgotności względnej (RH) i stężenia CO₂ przeprowadzono w 3 gimnazjalnych szkołach w Lublinie w sezonie grzewczym (H) i letnim (S). Szkoły były zlokalizowane w dzielnicach, w których większość prywatnych domów ogrzewana jest piecami węglowymi. W każdej ze szkół wybrano 2 klasy, w których wykonano pomiary przy obecności (L) i nieobecności (V) uczniów. Równoległe pomiary przeprowadzono dla powietrza zewnętrznego. Stosunki średnich koncentracji cząstek w klasach z uczniami i bez uczniów (L/V) były większe w sezonie grzewczym. Stosunki średnich koncentracji cząstek podczas pomiarów w sezonie grzewczym i letnim (H/S) były większe w klasach z uczniami. W obydwu sezonach średnie koncentracje PM i PN w klasach z uczniami wynosiły odpowiednio 239 μg/m³ i 7,4×10³/cm³, a w klasach bez uczniów 76 μg/m³ i 5,4×10³cm³. Ekspozycje uczniów w klasach były wyższe niż na zewnątrz i były średnio o ok. 50% większe w sezonie grzewczym. W obydwu sezonach zaobserwowano dodatnią korelację pomiędzy masową koncentracją grubych cząstek a temperaturą, RH i stężeniem CO₂ w powietrzu wewnętrznym. Koncentracje drobnych cząstek były ujemnie skorelowane z parametrami powietrza wewnętrznego w sezonie grzewczym i dodatnio w sezonie letnim.
