The paper provides an overview of Russian and foreign articles devoted to the study of the tree litter production and decomposition in forest ecosystems subjected to natural and anthropogenic factors. The spatial variability (below crown and between crown spaces) and the seasonal features of the tree litter production, its chemical composition and decomposition processes are poorly studied. In addition, most of the works, both in native and foreign countries science, highlight the influence of natural factors on the litter production and the processes of its decomposition, while the impact of point sources of industrial air pollution is rarely considered. The study of the variability of the size, fractional and chemical composition and processes of decomposition of tree litter under conditions of industrial air pollution is important for predicting the dynamics of forest ecosystems subjected to the combined action of natural and anthropogenic factors and reducing the negative impact of production processes on forests.

The Impact

High-frequency disturbance forest ecosystems undergo complex and frequent changes at various spatiotemporal scales owing to natural and anthropogenic factors. Effectively capturing the characteristics of these spatiotemporal changes from satellite image time series is a powerful and practical means for determining their causes and predicting their trends. Herein, we combined the spatiotemporal cube and vegetation indices to develop the improved spatiotemporal cube (IST-cube) model. We used this to acquire the spatiotemporal dynamics of forest ecosystems from 1987 to 2020 in the study area and then classified it into four spatiotemporal scales. The results showed that the cube-core only exists in the increasing IST-cubes, which are distributed in residential areas and forests. The length of the IST-cube implies the duration of triggers. Human activities result in long-term small-scope IST-cubes, and the impact in the vicinity of residential areas is increasing while there is no change within. Meteorological disasters cause short-term, large scope, and irregular impacts. Land use type change causes short-term small scope IST-cubes and a regular impact. Overall, we report the robustness and strength of the IST-cube model in capturing spatiotemporal changes in forest ecosystems, providing a novel method to examine complex changes in forest ecosystems via remote sensing.

This article marks the first attempt on Polish and European scale to identify the relationship between urban and industrial air pollution and the health conditions of urban populations, while also estimating the financial burden of incidence rates among urban populations for diseases selected in the course of this study as having a causal relation with such incidence. This paper presents the findings of a pilot study based on general regression models, intended to explore air pollutants with a statistically relevant impact on the incidence of selected diseases within the Agglomeration of Gdańsk in the years 2010–2018. In discussing the city’s industrial functions, the study takes into consideration the existence within its limits of a large port that services thousands of ships every year, contributing substantially to the volume of emissions (mainly NOx and PM) to the air. The causes considered include the impact of air pollution, seasonality, land- and sea-based emissions, as well as their mutual interactions. All of the factors and their interactions have a significant impact (p ≤ 0.05) on the incidence of selected diseases in the long term (9 years). The source data were obtained from the Polish National Health Fund (NFZ), the Agency for Regional Monitoring of Atmosphere in the Agglomeration of Gdańsk (ARMAAG), the Chief Inspectorate of Environmental Protection (GIOŚ), and the Port of Gdańsk Harbourmaster. The study used 60 variables representing the diseases, classified into 19 groups. The resulting findings were used to formulate a methodology for estimating the financial burden of the negative health effects of air pollution for the agglomeration, and will be utilized as a reference point for further research in selected regions of Poland.

It is time we settled down to a sensible, practical approach to solving the industrial air pollution problem. That is the goal of this paper: to take the sensationalism out and replace it with a sensible evaluation of the situation. The major points covered are 1 a brief review of historical facts, 2 an analysis of present conditions around the world, 3 what is industry’s responsibility, 4 a comparison of legislative procedures and their enforcement effectiveness, 5 the impact of air pollution control costs on worldwide markets, 6 suggestions for solutions.

The Impact

The Etang-de-Berre area is a large industrialized area in the South of France, exposing 300,000 inhabitants to the plumes of its industries. The possible associated health risks are of the highest concern to the population, who asked for studies investigating their health status. A geographical ecological study based on standardized hospitalizations ratios for cancer, cardiovascular, and respiratory diseases was carried out over the 2004–2007 period. Exposure to air pollution was assessed using dispersion models coupled with a geographic information system to estimate an annual mean concentration of sulfur dioxide (SO2) for each district. Results showed an excess risk of hospitalization for myocardial infarction in women living in districts with medium or high SO2exposure, respectively, 38% [CI 95% 4 : 83] and 54% [14 : 110] greater than women living in districts at the reference level exposure. A 26% [2 : 57] excess risk of hospitalization for myocardial infarction was also observed in men living in districts with high SO2levels. No excess risk of hospitalization for respiratory diseases or for cancer was observed, except for acute leukemia in men only. Results illustrate the impact of industrial air pollution on the cardiovascular system and call for an improvement of the air quality in the area.

It has been shown that the status of some Karelian water bodies had changed as a result of human impact and atmospheric precipitation has a role in the surface waters’ chemical composition formation. Assessment of biogenic elements and organic matter input to the Lake Onego and the Lake Ladoga from various natural and anthropogenic sources has been done. Higher load from point sources in comparison with diffuse sources has been registered for the Lake Onego in comparison with the Lake Ladoga. Many-year change of the Vygozero reservoir water chemical composition has been presented. This reservoir receives the Segezh paper-pulp plant waste waters and the Kenti River system waters with technogenic waters from the Kostomuksha mining/concentrating plant. It has been stated that atmospheric precipitations serve the main source of the biogenic elements and heavy metals input, while input of mineral and organic substances with the precipitation is insignificant. For the first time assessment of the Karelian water bodies’ state caused by the natural, climatic, and anthropogenic factors’ impact has been done.

ABSTRACT Seabird restoration plans require reliable estimates of the birds directly affected by a spill and the impact of that mortality on populations. They also require restoration techniques known to increase the rate of natural recovery. Unfortunately, restoration proposals have been hindered by damage assessments based on outdated and/or inappropriate data, exaggerated estimates of damages, and a lack of proven restoration techniques. Regular monitoring of seabird resources, knowledge of natural and anthropogenic factors influencing populations, and recognition of the typically limited role humans can play in seabird restoration will lead to the development of more realistic restoration plans.
