摘要: This investigation examined whether lead shot from duck shooting was acting as a source of in an alkaline wetland ecosystem typical popular duck-shooting areas Western Australia. A polluted urban and pristine were also studied for comparison. Lake Wannamal receives estimated 82 kg per year no any other known source. Monger to receive 138 road runoff, leachate sanitary landfill site, aerosols. Thomsons has human activities. Lead concentrations sediments did not differ significantly (P < 0.05) between apparently represent natural background levels. contaminated (mean: 192 ± µg Pb g-1 dry weight); the main appeared be runoff nearby freeway. Lead Baumea articulata Blake, Typha orientalis Presl Schoenoplectus validus Love generally low; roots higher than those leaves, suggesting that is poorly translocated. Lead submerged macrophytes similar, which may attributable periphyton on plants binding seston resuspended by water turbulence. The cyanobacterium Microcystis sp. accumulated low concentrations, believed soluble column. Macroinvertebrates but evidence found biomagnification. only slightly macroinvertebrates lakes, indicating uptake poor even lake.
