Abstract: 

Penicillin residues in animal food products like milk and meat has attracted great concern by health

regulatory agencies due to their negative effects. Therefore, there is urgent need for reliable, low cost,

fast and simple analytical tools/methods to monitor these penicillin residues in animal products before

distribution to consumers. In our previous work, we developed a square wave voltammetric method

Abstract: Artisanal gold-mining (AGM) is one of the most important activities in the districts of Migori and Transmara (Kenya). Gold-mining, however, is known to release vast quantities of arsenic and metals (some of which are very toxic like As, Hg, Cd, or Pb), which poses a serious threat to not only miners but also to the ecosystem and local populations.

Abstract: Community vulnerability to climate change can be conceptualized as an aggregate of three vulnerability components: exposure to climatic stress, sensitivity to climate stress and adaptive capacity. However, even within similar regions these vulnerability components are spatially differentiated necessitating the understanding of a regions vulnerability pattern before targeting adaptation assistance.
