Microwave assisted digestion followed by ICP-MS for determination of trace metals in atmospheric and lake ecosystem

The study of trace metals in the atmosphere and lake water is important due to their critical effects on humans,aquatic animals and the geochemical balance of ecosystems. The objective of this study was to investigate the concentration of trace metals in atmospheric and lake water samples during the rainy season(before and after precipitation)between November and December 2015. Typical methods of sample preparation for trace metal determination such as cloud point extraction,solid phase extraction and dispersive liquid–liquid micro-extraction are time-consuming and difficult to perform; therefore,there is a crucial need for development of more effective sample preparation procedure. A convection microwave assisted digestion procedure for extraction of trace metals was developed for use prior to inductively couple plasma-mass spectrometric determination. The result showed that metals like zinc(133.50–419.30 μg/m~3)and aluminum(53.58–378.93 μg/m~3)had higher concentrations in atmospheric samples as compared to lake samples before precipitation.On the other hand,the concentrations of zinc,aluminum,chromium and arsenic were significantly higher in lake samples after precipitation and lower in atmospheric samples. The relationship between physicochemical parameters(pH and turbidity)and heavy metal concentrations was investigated as well. Furthermore,enrichment factor analysis indicated that anthropogenic sources such as soil dust,biomass burning and fuel combustion influenced the metal concentrations in the atmosphere.

A holistic framework for design of cost-effective minimum water utilization network

Water pinch analysis (WPA) is a well-established tool for the design of a maximum water recovery (MWR) network. MWR, which is primarily concerned with water recovery and regeneration, only partly addresses water minimization problem. Strictly speaking, WPA can only lead to maximum water recovery targets as opposed to the minimum water targets as widely claimed by researchers over the years. The minimum water targets can be achieved when all water minimization options including elimination, reduction, reuse/recycling, outsourcing and regeneration have been holistically applied. Even though WPA has been well established for synthesis of MWR network, research towards holistic water minimization has lagged behind. This paper describes a new holistic framework for designing a cost-effective minimum water network (CEMWN) for industry and urban systems. The framework consists of five key steps, i.e. (1) Specify the limiting water data, (2) Determine MWR targets, (3) Screen process changes using water management hierarchy (WMH), (4) Apply Systematic Hierarchical Approach for Resilient Process Screening (SHARPS) strategy, and (5) Design water network. Three key contributions have emerged from this work. First is a hierarchical approach for systematic screening of process changes guided by the WMH. Second is a set of four new heuristics for implementing process changes that considers the interactions among process changes options as well as among equipment and the implications of applying each process change on utility targets. Third is the SHARPS cost-screening technique to customize process changes and ultimately generate a minimum water utilization network that is cost-effective and affordable. The CEMWN holistic framework has been successfully implemented on semiconductor and mosque case studies and yielded results within the designer payback period criterion.
