| statistical comparison between consecutive winter and summer concentrations in zinc and lead from sediments in a tropical urban estuary in mauritius. | zn and pb were quantified using atomic absorption spectrometry from urban and rural estuarine sediments collected along the western coast of mauritius over three consecutive dry winter and wet summer periods from august 2004 to february 2009. the mean concentrations of zn (204.0 +/- 92.3 mg kg(-1)) and pb (44.5 +/- 16.4 mg kg(-1)) in sediments at sable noir, an urban estuary, can be considered below those from contaminated estuarine sediments in industrialised countries. pb significantly decreas ... | 2010 | 19680757 |
