Số lượng tổng hợp các nguồn, khai thác mỏ, sản xuất, và phát tán môi trường của chì, kẽm ở Ba Lan, Chương 10 cho thấy sự cần thiết và tiềm năng cho một chính sách quốc gia về đất ngập nước lọc. | Part III Lead and Wetlands in Poland Part III contains studies by the research team at Krakow Poland on the Biala River marshes that have received lead and zinc wastewaters for 200 years. Chapter 9 contains the ecological and chemical studies by Wlodzimierz Wojcik and Malgorzata Wojcik. By quantitatively summarizing the sources mining manufacturing and environmental dispersal of lead and zinc in Poland Chapter 10 shows the need and potential for a national policy on wetlands filtration. 2000 by CRC Press LLC CHAPTER 9 Lead and Zinc Retention in the Biala River Wetland of Poland Wlodzimierz Wojcik and Malgorzata Wojcik CONTENTS Introduction.97 Site Description and History.98 Methods.98 Results.100 Soils and Sediments.100 Plant Communities and Biomass.105 Missing Species.105 Diversity.105 Concentration of Heavy Metals in Plant Tissues.107 Physical and Chemical Analysis of Waters.107 Upstream-Downstream Measurements.107 Field Experiment.109 Proposal to Restore Water Flow over the Wetland.109 INTRODUCTION The Biala River Wetland in southern Poland has received mine water discharges containing high concentrations of zinc and lead for about 400 years providing a rare opportunity to study long-term filtration of heavy metals by a wetland. Application of the wetlands for treatment of industrial wastewater and as a sink for pollutants is questioned by some professionals. Among their concerns is a problem of long-term tolerance of wetland plants to high concentrations of heavy metals in their tissues as well as in soil. This chapter presents the results of investigations of these heavy metals in the wetland and the rates of filtration. 97 2000 by CRC Press LLC 98 HEAVY METALS IN THE ENVIRONMENT USING WETLANDS FOR THEIR REMOVAL SITE DESCRIPTION AND HISTORY The Biala River is located 60 km west of Krakow City Poland. The distance between the river source and its outlet is about 11 km. The wetland study site is located at the confluence of the Biala River and two discharge .
