[en] Environmental degradation due to oil activities in the oil rich Niger Delta of Nigeria is daily approaching a non-tolerance level. Pollutants come from various aspects of operation ranging from seismic operations through drilling to the refinery stage. Gas flared daily by Oil Companies constitute a major health hazard in this country. Environmental pollution due to gas flaring at Oyigbo area of Rivers State is hereby reported. Surface temperature-distance variations were investigated for both dry (March) and rainy (June) seasons. Physical and chemical properties of the rainwater from the areas were also measured and analysed. The results show a surface temperature elevation of about 4.1 Celsius above the mean normal diurnal temperature within a 3.00 km. radius. An average pH 4.25 was recorded thus showing the acidic nature of the environmental rainwater from the area. All other measured parameters showed serious deviations from standards. This temperature elevation and increased acidity of the rainwater have enormous influence on socio-economic lives and the activities of the populace especially on their source of income which is mainly small scale farming. It is therefore necessary that Government agencies empowered to monitor environment especially FEPA should implement all the existing legislation on gas flaring and be more involved in the design and location of gas flaring stacks. These stacks should be located at least 2 km. from towns and villages

[en] Conservative estimates of global natural mercury fluxes into the atmosphere suggest a total of 500 t/a originating from the mercuriferous belt and about 200 t/a degassing from background soils. Recent flux measurements at different terrestrial sites suggest that mercury emissions and re-emissions from terrestrial sites have been significantly underestimated. This could result in an inaccurate ratio between natural and anthropogenic sources in global emission inventories. However, all this estimates are based on a fairly raw database, and considering that, it becomes clear that an accurate assessment of air/surface exchange processes will be critical to refine the global mercury cycle. For upscaling mercury fluxes derived from field experiments to regional or global scales a detailed process understanding of the driving forces behind air/surface exchange is imperative.We studied the influence of environmental parameters on mercury fluxes for 8 different soils

[en] Highlights: • SO₂ emissions under no interregional trade in China were estimated. • Interregional trade increased emissions by 28% compared to no-trade in China. • Exchanges of pollution-intensive products led to notable environmental inequities. • Adjusting trade patterns within China to achieve mitigation is recommended. -- Abstract: Embodied emissions in trade have been widely studied; however, there is still a lack of studies that explore whether a country is benefitting from its inter-regional trade in terms of pollutant emissions. This study took sulfur dioxide (SO₂) emissions as an example and employed modified input-output (MIO) model and traditional input-output (IO) model to quantify emissions under no-trade and trade conditions, and further investigated environmental efficiency and equality of inter-regional trade in China in 2010. The results show that inter-regional trade had increased emissions by 28% compared to no-trade emissions, which confirms the environmental inefficiency of inter-regional trade in China. This was largely because regions with better technology and low emission intensities tended to outsource the production of pollution-intensive but low value-added goods to regions with high emission intensities through inter-regional trade. The exchanges of pollution-intensive products in inter-regional trade have led to notable environmental inequities. Eastern regions usually gained the greatest environmental benefits from trade, while central regions (especially Shanxi, Henan, and Hebei) suffered the largest environmental loss induced by trade. Specifically, Guangdong plundered other regions the most (796 G gram (Gg)), while Shanxi was plundered the most by other regions (790 Gg). Polices to differentiate reduction criteria for emission intensity in different regions and adjust trade patterns within China could be recommended in order to achieve trade-related environmental efficiency as well as environmental equality.

[en] The article is divided in three parts; in the first one it is the problem of the identification and the control of the environmental impact and of the sources of due contamination to the industry or the family sector; in second part they are considered the methods used for the transformation of existent plants and the setting in march of new plants; and in third part they are considered the implementation difficulties and the perspectives of success of the clean technologies. The work concludes that it is necessary to study the problem in their group, it is convenient to apply the possible solutions, be not still good

[en] The first step toward finding a solution to the problems with air pollution is the realization of a land survey map of polluters and a constant acquisition of data from periodical controls of emission of harmful materials, which will be carried out with a determined dynamic. Such a land survey map is not a project which should be finished within a strict time limit, but is intended to create all conditions for a periodical monitoring of emission of harmful materials from registered polluters in order to make a periodical, exact picture of the quantity of harmful materials, which are conveyed by polluters in certain city, a part of the state or the whole country.

[en] The emission limits and measurement methods of pollutants from ship engines (China’s first and second stages) implemented on July 1, 2018 (GB15097-2016) marked the initial establishment of China’s ship air pollutant emission standard system. Based on the study of the development of China’s ship air pollutant emission standards, this paper analyzes the applicable ships and the types of pollutants controlled by China’s ship air pollutant emission standards system, and puts forward some suggestions to improve China’s ship air pollutant emission standards system.

[en] An updated second edition of 'Pollution: Causes, Effects and Control' has been published in eighteen chapters. Topics covered include various aspects of water and air pollution, health effects of environmental chemicals, the legal control of pollution, the control of industrial pollution, organometallic compounds in the environment, radioactivity in the environment and quantitative systems methods in evaluation of environmental pollution problems. The chapter on various aspects of radioactivity in the environment was selected and indexed separately. (U.K.)

[en] The report discusses how the Norwegian pulp and paper industry has adapted to the emission requirements given by the Norwegian Pollution Control Authority (SFT) during the last 30 years. The authors have identified process alterations and internal measures in the factories that are due to stricter emission requirements, and they have identified external cleaning measures. The report also documents the interaction between the companies and SFT and it maps out real and permitted emissions to water and air from the Norwegian pulp and paper industry

[en] Pollution prevention (P2) results from the combined effect of the public opinion, a new environmental value system, government regulation, but above all, the search for an economic development within the context of environmental protection. The reasons for prevention are fundamental: profit from a new economic frontier; reduced potential for civil and criminal liability; and the effective and economic protection of the environment. This paper addresses, among other relevant issues, the following topics: justification and objective of pollution prevention; strategy and methodology for its implementation; examples of successes and tools; benefits and barriers and some recommendation
