Download or read book Ambient Air Particulate Lead Concentrations in Canada 1975 1983 written by Canada. Environment Canada and published by Environnement Canada. This book was released on 1985 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data for airborne lead concentrations in Canada between 1975 and 1983 show that annual average lead levels decreased by 55% inthis period. A lower lead content in gasoline and lower demandfor gasoline account for this decrease in airborne leadconcentration. A comparison with U.S. data confirms thisconclusion and shows that further reductions in ambient leadlevels can be accomplished by decreasing the lead content ingasoline.

Available in PDF, EPUB and Kindle. Book excerpt: Biology of Benthic Organisms contains papers presented at the 11th European Symposium on Marine Biology, held at Galway, Ireland in October 1976. The collection contains 63 papers discussing the biological aspects of benthic organisms. The authors, mostly marine biologists, provide articles discussing their studies of marine life from different bodies of water from around the world. Topics on community structures of soft-bottom macrofauna in different parts of the Baltic; studies on anaerobic nitrogen fixation in the sediments of two Scottish sea-lochs; distribution of benthic phyto- and zoocoenoses along a light gradient in a superficial marine cave; and structural features of a North Adriatic benthic community are discussed in detail. Marine biologists, botanists, zoologists, and biologists will find the book invaluable.
Download or read book Farm Land Erosion written by S. Wicherek and published by Elsevier. This book was released on 2012-12-02 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last twenty years, mutations within agricultural systems in France and Europe have brought on a spectacular worsening of soil erosion and degradation. This volume, contributed to by scientists from 25 countries, discusses how this risk can be evaluated, and which solutions should be adopted without radically disturbing the socio-economic orientation of major agricultural regions. It is an excellent starting point for the development of new research themes, and will be of great value to soil and environmental scientists, and to all those involved in land irrigation and drainage.

Available in PDF, EPUB and Kindle. Book excerpt: The National Air Pollution Surveillance Program is a joint project of the federal and provincial levels of government to monitor and assess, on a continuing basis, the quality of the ambient air in the urban regions of Canada. This annual summary presents data reported from over 500 sampling instruments in more than 50 cities across the 10 provinces and the 2 territories. Measurements were made for sulphur dioxide, carbon monoxide, nitrogen dioxide, ozone, soiling index, suspended particulates, lead, sulphate, and nitrate. The summary also compares the data for the year with national air quality objectives for sulphur dioxide, carbon monoxide, nitrogen dioxide, ozone and suspended particulates.
