This paper uses innovation strengths indicators based on pollution prevention and abatement (or antipollution) patents lodged at the US Patent and Trademark Office for the period 1975-2002 to: (i) analyse trends in the patenting of anti-pollution technologies in the USA; and (ii) provide international rankings for the development of anti-pollution technologies. Annual data used for the innovati...

Air pollution can affect health and well-being of people and ecosystems. Due to the health risk posed for sensitive population groups, it is important to provide with hourly and daily forecasts of air pollution. One way to assess air pollution is to make use of the Common Air Quality Index (CAQI) of the European Environment Agency (EEA). In this paper we employ a number of Computational Intelli...

BACKGROUND This study investigates the effects and mechanism of sulfur dioxide (SO2) inhalation and exercise on rat myocardial collagen fiber. MATERIAL AND METHODS The rats were randomly divided into 4 groups: a control group (RG), an exercise group (EG), an SO2 pollution group (SRG), and an SO2 pollution and exercise group (SEG). Body weight, cardiac index, and left ventricular index in each g...

the investigation at water quality of kelaroud river by hfbi (hilsenhoff’s family–level biotic index) method. in this research task to the water quality of kelaroud river using biotic index hfbi and identifying the society of macroinvertebrates upon level of the family. result of this index with other index compared: ept/ chironomidae, .this task was achieved with in the year 1389-90 with takin...

Gold mining is now widely acknowledged as one of the significant sources soil pollution in developed countries. In developing countries, and levels contamination have not been thoroughly addressed. Thus, this study was intended to determine source level active closed gold areas. The research paper presents load heavy metals (lead-Pb, chromium-Cr, cadmium-Cd, copper-Cu, arsenic-As, manganese-Mn,...

We assessed the spatial and temporal variations of pollution indicators and geochemical and trace metal parameters (23 in total) from water and sediment (144 samples) of three different eco-niches (beach, fishing harbor, and estuary) in larger coastal cities of southern India (Cuddalore and Pondicherry) for one year. A total of 120 marine Pseudomonas isolates were challenged against different c...

The objective of this study was to investigate the concentration and spatial distribution patterns of six potentially toxic heavy metal elements (Mn, Zn, Cr, Pb, Cu and Ni) in bus station dusts in the Xifeng district of Gansu province, NW China. The contents were analyzed for Mn, Zn, Cr, Pb, Cu and Ni by using S8 TIGER Brochures wavelength dispersive X-ray fluorescence spectrometry. Geoaccumula...

In this paper we present the recently proposed approach InterCriteria Analysis (ICA) for the Mesta River pollution modelling in Bulgaria. The approach is based on the apparatus of the index matrices and the intuitionistic fuzzy sets. We have applied the ICA to establish the basic pollution relations (the model structure) based on different criteria involved in the Mesta River. The results have ...
