Solid phase extraction of trace metals from environmental samples using Amberlite XAD-7 loaded with 2-hydroxy-propiophenone-4-phenyl-3-thiosemicarbazone and determination by inductively coupled plasma–atomic emission spectrometry

A method for the solid phase extraction of trace metals, namely Co, Cu, Pb, Ni and Zn, from environmental and biological samples using column Amberlite XAD-7 loaded with 2-hydroxy-propiophenone-4-phenyl-3-thiosemicarbazone (HPPPTSC) and determination by inductively coupled spectrometry (ICP–AES) has been developed. The reagent has the capacity to form chelate complexes with the metals because of three binding sites in the reagent molecule. The optimum experimental conditions for the quantitative sorption of five metals, pH, effect of flow rate, concentration of eluent, sorption capacity and the effect of diverse ions on the preconcentration of analytes have been investigated. The sorption capacity of the resin has 83, 127, 35, 88 and 85?µmol?g^?1 for Co²⁺, Cu²⁺, Pb²⁺, Ni²⁺ and Zn²⁺, respectively. The preconcentration factors for Co²⁺, Cu²⁺, Pb²⁺, Ni²⁺ and Zn²⁺ were 100, 110, 120, 140 and 150, respectively. The accuracy of the proposed procedure was evaluated by standard reference materials. The achieved results were in good agreement with certified values. The proposed method was applied for the determination of trace metals in river water and plant leaves.     

How might adaptation to climate change by smallholder farming communities contribute to climate change mitigation outcomes? A case study from Timor-Leste,Southeast Asia

The agriculture industry is significantly exposed to the impacts of climate change, and is also responsible for contributing extensive greenhouse gas emissions. As a way of responding to both adaptation and mitigation challenges within the industry, this article examines how community-based climate change adaptation initiatives might provide mitigation outcomes in the agriculture sector in Timor-Leste. Beginning with an exploration of nation-wide institutional responses to climate change, the study utilises interviews, field observations and document analysis to examine an extensive community-based adaptation program in two districts in Timor-Leste focused on increasing the resilience of the agriculture sector and the livelihoods of poor rural farmers. Analysis of this program reveals a largely synergistic relationship between adaptation measures focused on land and water management and agriculture and their corresponding greenhouse gas mitigation potential, including co-benefits such as soil/atmospheric carbon sequestration, reduced emissions, soil nitrification and reduced use of inorganic fertilisers. Community-based adaptation programs in the agriculture sector have a significant influence on mitigation outcomes, which is often overlooked in community-based programs. The adaptation program in Timor-Leste has provided useful insights into the inter-relationships between adaptation and mitigation at the community level, which could be further supported and scaled-up in other Southeast Asia countries and elsewhere.
