Mosquito breeding survey Vesteys Lake 15 January 2008
Medical Entomology DHCS, 2008Co-Authors: Warchot AllanAbstract:Updated in February 2009.Vesteys Lake is one of the most significant and productive mosquito breeding sites in Darwin Urban for the northern salt marsh mosquito Aedes vigilax. Historically the area was a disturbed salt marsh/Mud Flat habitat with numerous tidal pools and drainage lines, which were breeding sites for Ae. vigilax and other mosquito species (PER 1988). Aedes vigilax is the principal pest mosquito in areas of Darwin Urban near the coast, and is a potential vector of Ross River virus (RRV) and Barmah Forest virus (BFV). The Conservation Commission of the NT commenced construction of the lake in 1988, and Darwin City Council assumed responsibility of the lake some time after construction was completed. The construction of the lake and surrounds resulted in the creation of new and extensive Aedes vigilax breeding sites. The lake itself has never become a mosquito breeding site, but the surrounding landscape has been a significant breeding site for Aedes vigilax from the inception of the lake to the present, 20 years later. The mosquito breeding sites were the result of suitable grades not being applied to many areas. There has been some works over the years by Medical Entomology and DCC (under the combined Mosquito Engineering Program) to remove mosquito breeding sites, which have been successful in reducing the extent of various mosquito breeding sites, but there are still further works required to prevent mosquito breeding

heavy metal distribution in different soil aggregate size classes from restored brackish marsh oil exploitation zone and tidal Mud Flat of the yellow river delta
Journal of Soils and Sediments, 2016Co-Authors: Rong Xiao, Mingxiang Zhang, Feihai YuAbstract:Purpose Heavy metal distribution in soils is affected by soil aggregate fractionation. This study aimed to demons trate the aggregate-associated heavy metal concentrations and fractionations in “sandy,” “normal,” and “Mud” soils from the restored brackish tidal marsh, oil exploitation zone, and tidal MudFlat of the Yellow River Delta (YRD), China.

Journal of Soils and Sediments, 2016Co-Authors: Rong Xiao, Mingxiang Zhang, Xinying Yao, Junhong BaiAbstract:Heavy metal distribution in soils is affected by soil aggregate fractionation. This study aimed to demons trate the aggregate-associated heavy metal concentrations and fractionations in “sandy,” “normal,” and “Mud” soils from the restored brackish tidal marsh, oil exploitation zone, and tidal MudFlat of the Yellow River Delta (YRD), China. Soil samples were sieved into the aggregates of >2, 0.25–2, 0.053–0.25, and 2 mm aggregates indicated contribution of carbonates to soil aggregation and metal adsorption in tidal Mud Flat. Soil type and aggregate distribution were important factors controlling heavy metal concentration and fractionation in YRD wetland soil. Compared with Mud soil, normal soil contained increased concentrations of F5 and F3 of metals in the 0.053–0.25 mm aggregate, and sandy soil contained increased concentrations of bioavailable and total Cr, Ni, and Zn with great contribution of mass loadings in the <0.053 mm aggregate. The results of this study suggested that oil exploitation and wetland restoration activities may influence the retention characteristics of heavy metals in tidal soils through variation of soil type and aggregate fractions.
