资源简介:
Elemental (including Al, As, B, Ba, Be, Ca, Cd, Ce, Co, Cr, Cu, Fe, Ga, Gd, Ge, K, La, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, S, Sc, Si, Sr, Th, Ti, V, Y, Zn, Zr) concentrations, pH, electrical conductivity, microplastics, Longitude-Latitude and UTM Zone 50 coordinates, sample material type, sampling strata, and sample identification codes for 231 samples of sediment or soil collected in 2019, 2020, and 2021 from Ashfield Flats Reserve, an urban nature reserve in Western Australia.
Ashfield Flats Reserve (approx. 40 ha) is listed as a Western Australian Bush Forever Site (No. 214) and fringes the Swan-Canning Estuary. It is also listed in the Directory of Important Wetlands in Australia and contained a threatened ecological community of temperate saltmarsh plant species. It is the largest remaining salt marsh in the Swan-Canning Estuary, but is impacted by altered hydrology, several stormwater drains, and poor water quality from historical groundwater contamination.
Sampling and analysis was conducted to assess the severity and extent of contamination of sediments and soils with trace elements, nutrients, and microplastics. In particular it was of interest whether stormwater drains which cross the reserve were contributing contaminants to adjacent wetlands.
本数据集涵盖2019至2021年间于西澳大利亚州城市自然保护区阿什菲尔德平原保护区(Ashfield Flats Reserve)采集的231份沉积物与土壤样品的相关检测数据,具体包括:元素(含铝(Al)、砷(As)、硼(B)、钡(Ba)、铍(Be)、钙(Ca)、镉(Cd)、铈(Ce)、钴(Co)、铬(Cr)、铜(Cu)、铁(Fe)、镓(Ga)、钆(Gd)、锗(Ge)、钾(K)、镧(La)、镁(Mg)、锰(Mn)、钼(Mo)、钠(Na)、铌(Nb)、钕(Nd)、镍(Ni)、磷(P)、铅(Pb)、硫(S)、钪(Sc)、硅(Si)、锶(Sr)、钍(Th)、钛(Ti)、钒(V)、钇(Y)、锌(Zn)、锆(Zr))浓度、pH值、电导率、微塑料含量、经纬度与UTM 50区坐标系坐标、样品基质类型、采样层位以及样品识别码。
阿什菲尔德平原保护区占地约40公顷,被列入西澳大利亚州“永久丛林”(Bush Forever)计划站点(编号214),毗邻天鹅-坎宁河口(Swan-Canning Estuary)。该保护区同时入选《澳大利亚重要湿地名录》,境内存在受威胁的温带盐沼植物物种生态群落,是天鹅-坎宁河口现存规模最大的盐沼湿地,但当前受到水文条件改变、多条雨水排水渠以及历史地下水污染导致的水质恶化的负面影响。
本次采样与分析工作旨在评估沉积物与土壤受微量元素、营养盐及微塑料污染的严重程度与波及范围,其中重点关注横穿保护区的雨水排水渠是否会向邻近湿地输入污染物。
