Combined effects of copper and cadmium on Chlorella pyrenoidosa H.Chick: subcellular accumulation,distribution, and growth inhibition

Disposal of waste into aquatic ecosystems may cause microalgae to be exposed to various metals, e.g. copper and cadmium. The effects caused by combinations of metals may be more serious. Evaluations of subcellular fate, bioaccumulation, and biological effects of metals on aquatic organisms are generally derived from experiments with individual metals. The present study aims to evaluate the effects of exposure of Chlorella pyrenoidosa to copper and cadmium in combination on subcellular accumulation, distribution, and growth. The algae were exposed for 72 h to copper at concentrations of 13 – 25 µmol L^?1, cadmium at about 6 µmol L^?1, and combinations thereof. The levels of copper and cadmium in subcellular organelles, heat-denaturated protein, metal-rich granules, and heat-stable protein were determined by atomic absorption spectrometry. Exposure of C. pyrenoidosa to copper and cadmium in combination inhibited growth more strongly than copper and cadmium individually. Highest accumulation was observed in metal-rich granules and heat-stable proteins. Administration of both metals in combination affected their subcellular distribution: copper was mainly distributed into the metal-rich granules (70%–80%) and heat-stable proteins (9%–24%), cadmium in the metal-rich granules (88%–98%).     

A market modeling review study on predicting Malaysian consumer behavior towards widespread adoption of PHEV/EV

With the rising concern about climate change, there has been an increased public awareness that has resulted in new government policies to support scientific research for mitigating these problems. Malaysia is among the major energy-intense countries and is under an excessive burden to advance its energy efficiency and to also work towards the reduction of its carbon emission. Plug-in hybrid electric vehicles (PHEVs) have the potential to lessen the carbon emission and gasoline consumption in order to alleviate environmental problems. Most of the energy problems linked to the increasing transportation pollution are now being reduced with the solution of the adoption of PHEVs. PHEVs are seen as a solution to cut carbon emission, which prevents environmental damages. Furthermore, PHEVs’ driving range and performance can be comparable to the other hybrid vehicles as well as the conventional IC engines that have gasoline and diesel tanks. Thus, many efforts are being initiated to promote the use of PHEVs as an innovative and affordable transportation system. In order to achieve making the consumers aware of the adoption of PHEVs, we used a model which is based on the extended theory of planned behavior (TPB). This review is based on the factors affecting the adoption of PHEVs among Malaysian consumers. The model takes into account the ten key features that influence the adoption of PHEVs, such as environmental concern, personal norm, attitude, vehicle ownership costs, driving range, charging time, intention, subjective norm, perceived behavioral control, and personal norm. All these constructs are drivers towards the adoption of PHEVs. These factors affect the relationship between the adoption of PHEVs and how consumers intend to protect the environment. This review is based on improving how the “attitude-action” gap is understood as it is an important element for further studies on PHEVs. The aim of the research is to come up with a framework that examines how to modify the consumer’s environmental concerns in acquiring PHEVs. This will pave the way for more academic research and future works that can emphasize how to obtain empirical results. The authors’ recommendation is that, before a consumer’s behavior is assessed and considered, an observation of the current technology is needed with methods and knowledge of the existing technology adoption aspect.     

A study on rescuer drowning and multiple drowning incidents

IntroductionDrowning is a leading cause of injury related death in many countries, including Turkey, where this study originates. The aim of the study is to define and examine “rescuer” drowning and Multiple Drowning Incidents (MDIs), and suggest preventative measures against MDIs.MethodThe event of a person drowning can be complicated if an untrained person attempts to rescue the Primary Drowning Victim (PDV). This can result in the death of the “rescuer” as well as the PDV, which then becomes an MDI. This study categorizes these MDI incidents by examining online news media accounts in Turkey from 2005 through 2008.ResultsIn this 4-year period, 88 “rescuer” drowning incidents occurred in which 114 “rescuers” and 60 PDVs died from drowning in MDIs; 114 drowned “rescuers” rescued 47 PDVs before they died from drowning. Most of the “rescuers” were male and 42.1% of them were under the age of 18. Most of the drowning incidents (68.5%) occurred in fresh water (lakes/dams/water holes and rivers/creeks/streams).ConclusionIn this study, risk factors for drowning deaths include gender and entering in unguarded open water. An increased awareness of such risks as well as promotion of both swimming and rescue skills in water could help reduce MDIs. Parents who live close to fresh water sources with boys under the age of 18 years should be more aware of drowning risk because of their higher rates of deaths from drowning.Impact on IndustryThe results of this study give the chance to policy makers and all other related people or organizations to see the whole picture of deaths by drowning and the results can be used to build up preventative strategies as swimming teaching and life guard education.
