Nob End is the site of a former waste tip which is now a Site of Special Scientific Interest〔(【引用サイトリンク】title= Nob End citation )〕〔(【引用サイトリンク】title=Map of Nob End )〕 and Local Nature Reserve〔(【引用サイトリンク】title=Nob End )〕〔(【引用サイトリンク】title=Map of Nob End )〕 near Little Lever and Kearsley, in Greater Manchester, England. ==History== Standing at the confluence of the River Irwell and River Croal the site was used around 1850-70 as a tip for toxic alkaline waste from the production of sodium carbonate (soda ash) by the Leblanc process.〔 The waste, known as "galligu", was a blue sludge (from reduced iron compounds) dominated by calcium sulphide and smelling of bad eggs. The surface of the waste has since weathered down to calcium carbonate, and calcicolous vegetation has colonised the site. As natural limestone grassland does not occur in Greater Manchester, many of the species found are rare in the county.〔 The 8.8 hectare site became a SSSI in 1988, and a Local Nature Reserve in 2000.〔(【引用サイトリンク】title=File SD 70/2: Nob End )〕 In 1936 a major breach in the now defunct Manchester Bolton & Bury Canal occurred east of the Nob End locks; it has never been repaired.〔(Pennine Waterways )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nob End」の詳細全文を読む スポンサード リンク
