The article discusses the study that determines the relevance of albino organisms, which are considered a useful tool for environmental lead monitoring, in Argentina. According to sources, albino Biomphalaria glabrata is a pulmonate freshwater gastropod, recommended as a bioindicator organism for environmental studies, and was found to use hemoglobin as a respiratory pigment. The study is intended to determine delta-aminolevulic acid dehydratase (ALA-D) activity in different tissues of albino B. glabrata. It is also intended to investigate the modifications of enzyme activity in tissues of gastropods exposed to different levels of lead of environmental relevance. The study shows that ALA-D activity in tissues of albino B. glabrata can be considered a sensitive biomarker of lead exposure. |
