Heavy metal pollution in the environment; bivalves as bio-monitors a 50-year review

There has been a steady increase in the quantity and diversity of discharges that reach aquatic environment, both organic and inorganic, either synthesized or mobilized by man as a result of high population growth and development activities. This has led to the appearance of several types of pollution. Inland and coastal waters have been the most affected, since most major cities are located near water bodies. Monitoring...

Understanding nexuses between precipitation changes and climate change and variability in semi-arid lowlands of Mwanga District, Tanzania

Contextually, precipitation fluctuated due to climate variability and evolved due to emissions of anthropogenic greenhouse gases and land-use changes since the industrial revolution in the 1880s. However, some studies problematised that there is little understanding of nexuses between precipitation changes and climate change and variability in tropical Africa. Therefore, this paper sought to assess such linkages in...
