Minor towns with population size of 50-100 thousand people are much rarely studied in regards of the ecological-hygienic assessment of human environment, in spite of the fact that they are characterized by specific ecological problems. The objective of the study was the hygienic assessment of the impact of urban environment on population health status in Tikhvin and Gatchina towns of the Leningrad region. Morbidity rate in the population of Tikhvin and Gatchina in 2005-2015, atmospheric emissions of industrial enterprises, findings on monitoring for both atmospheric air pollution and centralized drinking water supply, as well as motor transport noise levels were studied. Population health risk stipulated by industrial emissions and noise exposure was calculated. Statistical data treatment with correlation analysis of the relationship between environmental pollution indices and population morbidity was carried out. The study revealed increased atmospheric air pollutant concentrations in Gatchina, which might be connected with motor transport effect. Acute non-carcinogenic risk levels resulting from air pollutants are on the borderline of the admissible level, while in Tikhvin town those values are significantly lower. Estimated concentrations of atmospheric pollutants produced by industrial emissions are by 1.5-2 times lower than the actual levels shown by monitoring. Noise levels and predicted health risks in Gatchina are on the borderline of the admissible level, while in Tikhvin they are significantly reduced. The statistically significant gain in the general primary morbidity rate indices due to respiratory diseases in Gatchina town, correlated with atmospheric air pollution, was revealed. Our study showed that despite the presence of large industrial enterprises in studied towns, motor transport proved to be the key factor that forms air pollution and noise load, more typical of large cities.

This study evaluated the distribution of particulates (PM1, PM 2.5, PM 4, PM 7, PM 10, and TSP) around smallholder gari production facilities in the Niger Delta, Nigeria. The particulates were evaluated at 3 distances (3.05, 7.62, and 15.24 m) from emission source in the dry season (November, January, and March) and wet season (May, July, and September) in Delta, Bayelsa, Rivers, and Abia states. A mini-volume air sampler was used to assess the concentration of particulates, while health risk was assessed following standard protocol using median and geometric mean as reference values. The particulates ranged from 11.54 – 14.99 µg/m3, 18.70 – 22.34 µg/m3, 26.12 – 36.04 µg/m3, 37.00 – 52.26 µg/m3, 46.91 – 72.49 µg/m3 and 57.94 – 99.49 µg/m3 for PM1, PM2.5, PM4, PM7, PM10 and TSP, respectively. There were statistical variations (p<0.05) across months, distances, and locations of study and their interactions. The particulates correlates positively at p<0.01 with higher concentrations recorded for the dry season as opposed to the wet season, (indication of seasonal influence). The health risk assessment indicated a slight to moderate pollution in both seasons across the study area, which should be taken into advisement when considering long-term exposure to sensitive groups. Hence, there is a need to adopt a sustainable management of emissions due to gari production from cassava tuber.

We investigated the distribution of hazardous heavy metals (As, Cr6+, Ni, Cd, Pb, and Mn) and estimated the health risk related to the heavy metals in fine dust (PM-10 and PM-2.5) of Sasang industrial complex, Busan, Korea. The concentration of fine dust in the industrial complex was 1.2 times higher than in a residential area, while harmful heavy metals showed a difference of at least 1.3 times (Cd) and up to 6.5 times (Ni). The concentration of fine dust and carcinogenic heavy metals in the industrial complex increased significantly compared to the residential area in spring (March to May) and winter (December to February) months. A risk assessment was performed using Monte-Carlo simulations containing a four-step procedure. During hazard identification, As, Cr6+ Ni, Cd, and Pb were categorized as human carcinogens and probable human carcinogens and evaluated for their levels of excess cancer risk. For concentrations of over 90% Cr6+ and As, the excess cancer risk was over 10-5 (1 person per 100,000). The non-cancer hazard index of As, Cr6+, Cd, and Mn was below the limit value of 1.

This study examines environmental and health risk implications of air quality in the vicinity of the Port Harcourt airport road dumpsite. The study objectives are to determine air quality in the vicinity of the Port Harcourt airport road dumpsite of the municipal solid waste, examine the health risk implications of air quality in the study location, ascertain the environmental implications of the air quality in the vicinity of the dumpsite, and identify if there are variations in air quality in the different sections in the study location. Air quality was determined using standard operating procedures where samples were collected at the dump, 250 m and 500 m away from the dumpsite. The samples were collected in the morning, afternoon and evening hours of the same day. The samples collected from these locations were taken in-situ amongst which are (Co2, CH4, O2, Co, H2S, PM-2.5, PM-10, Ni, Cr, Temperature and RH). Survey questionnaire was administered, in order to complement the field results. Three hypotheses were also tested using ANOVA and the Chi-square analytical tool. The findings of the study show that Nickel and Chromium amongst other parameters were above the WHO standard limits. Therefore, the quality of air within the vicinity of the dumpsite is considered polluted. Consequently, URTI and skin rashes are the common ailments that are prevalent in the area of study. Thus, the municipal solid waste dumpsite constitutes both environmental and health implications to the human population within the vicinity of the Port Harcourt airport road dumpsite. In this regard, this study recommends that the citing of waste dump should be done in line with standard regulations and prohibits the development of residential settlements within 3 km radius from any dumpsite.

Particulate Matter Exposure

AbstractAir pollution is a growing problem worldwide, inducing and exacerbating several diseases. Among the several components of air pollutants, particulate matter (PM), especially thick (10–2.5 µm; PM 10) and thin (≤2.5 µm; PM 2.5), are breathable particles that easily can be deposited within the lungs, resulting in pulmonary and systemic inflammation. Although physical activity is strongly recommended, its effects when practiced in polluted environments are questionable. Therefore, the present study evaluated the pulmonary and systemic response of concomitant treadmill training with PM 2.5 and PM 10 exposure. Treadmill training inhibited PM 2.5- and PM 10-induced accumulation of total leukocytes (p<0.001), neutrophils (p<0.001), macrophages (p<0.001) and lymphocytes (p<0.001) in bronchoalveolar lavage (BAL), as well as the BAL levels of IL-1beta (p<0.001), CXCL1/KC (p<0.001) and TNF-alpha (p<0.001), whereas it increased IL-10 levels (p<0.05). Similar effects were observed on accumulation of polymorphonuclear (p<0.01) and mononuclear (p<0.01) cells in the lung parenchyma and in the peribronchial space. Treadmill training also inhibited PM 2.5- and PM 10-induced systemic inflammation, as observed in the number of total leukocytes (p<0.001) and in the plasma levels of IL-1beta (p<0.001), CXCL1/KC (p<0.001) and TNF-alpha (p<0.001), whereas it increased IL-10 levels (p<0.001). Treadmill training inhibits lung and systemic inflammation induced by particulate matter.

The Impact

The aim of this paper is to present the results of measurements, on the quality of internal and external environment, carried out during the cruise of the tall ship STS Fryderyk Chopin. The cruise took place between 16th and 30th September 2017 as part of the scientific seminar of the Warsaw University of Technology (WUT) on the Wave, addressed to students of the WTU. After leaving the port of Edinburgh, crossing the North Sea, the Danish straits, stops in Copenhagen and Kołobrzeg, the tall ship reached Szczecin after two weeks. The measurements carried out on the deck included the temperature and relative humidity of the indoor air in three cabins and the men’s bathroom. In two cabins, the CO2 concentration was measured additionally. The outdoor temperature, relative humidity and concentration of PM 1.0, PM 2.5 and PM 10 were also measured. The obtained results allowed to assess the quality of the internal environment in accordance with the standards and to analyze the effectiveness of the mechanical ventilation system. Measurements of particulate matter have shown significant differences between outdoor air quality in the open sea and in ports or near major shipping routes. It turned out that the impact of emissions from passing ships using diesel engines is clearly visible.
