Environmental Analysis – Lake Nakuru Flamingos: Heavy Metals

[vc_row hide_bg_image_on_tablet=”” hide_bg_image_on_mobile=”” css=”.vc_custom_1637026952492{background-color: #eae7e4 !important;}”][vc_column icons_position=”left”][vc_column_text]Toxic trace metals are possible culprits for the ongoing deaths of large numbers of lesser flamingos at Lake Nakuru, Kenya. In this section we explore the possible role of heavy metals in these deaths and examine instrumental methods utilized to evaluate levels of copper, zinc, lead and chromium present in Lake Nakuru sediment and suspended solid samples. These methods include anodic stripping voltammetry (ASV), atomic spectroscopy, and x-ray fluorescence spectroscopy (XRF). Data sets are provided for each technique so that current levels can be calculated and compared to those contained in a report published in 1998.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column icons_position=”left”][vc_custom_heading text=”Table of Contents” font_container=”tag:h3|text_align:center|color:%23000000″ use_theme_fonts=”yes”][/vc_column][/vc_row][vc_row][vc_column icons_position=”left”][vc_column_text]
