Arsenic and heavy metal contamination of rice, pulses and vegetables grown in Samta village, Bangladesh

Arsenic contaminated water from tube wells has become the major health problem threatening millions of people in Bangladesh. However, the arsenic (As) contaminated water is not just used for drinking, it is used to irrigate crops, and to wash and prepare food. Contamination of agricultural soils by long-term irrigation with As contaminated water can lead to contamination and phyto-accumulation of the food crops with As and other toxic metals. As a consequence, dietary exposure to As and other toxic metals may contribute substantially to the adverse health effects caused by the contaminated tube wells in Bangladesh. Various vegetables, rice, pulses and the grass pea were sampled in Samta village in the Jessore district of Bangladesh and screened for As, Cd, Cu, Pb and Zn by inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry. These local food crops provide the majority of the nutritional intake of the people in this area and are of great importance to their overall health. In general, our data show the potential for some vegetables to accumulate heavy metals with concentrations of Pb greater than Cd. The concentrations of As and Cd were higher in vegetables than in rice and pulses. The concentration of Pb was generally higher in rice than in pulses and vegetables. However, some vegetables such as bottle ground leaf, ghotkol, taro, eddoe and elephant foot had much higher concentrations of Pb. Other leafy and root vegetables contained higher concentrations oJ2n and Cu. Rice grown at Samta had increased Pb and As, but, considering an average daily intake of only 260 g rice per person per day, only the Pb is at concentrations which would be a health hazard/or human consumption.

Arsenic and heavy metal contamination of vegetables grown in Samta village, Bangladesh

Drinking of arsenic (As) contaminated well water has become a serious threat to the health of many millions in Bangladesh. However, the implications of contamination of agricultural soils from long-term irrigation with As-contaminated groundwater for phyto-accumulation in food crops, and thence dietary exposure to As, and other metals, has not been assessed previously in Bangladesh. Various vegetables were sampled in Samta village in the Jessore district of Bangladesh, and screened for As, Cd, Pb, Cu and Zn by inductively coupled plasma emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). These local food products are the basis of human nutrition in this region and of great relevance to human health. The results revealed that the individual vegetables containing the highest mean As concentrations (μg g⁻¹) are snake gourd (0.489), ghotkol (0.446), taro (0.440), green papaya (0.389), elephant foot (0.338) and Bottle ground leaf (0.306), respectively. The As concentration in fleshy vegetable material is low. In general, the data show the potential for some vegetables to accumulate heavy metals with concentrations of Pb greater than Cd. Some vegetables such as bottle ground leaf, ghotkol, taro, eddoe and elephant foot had much higher concentrations of Pb. Other leafy and root vegetables, contained higher concentrations of Zn and Cu. Bioconcentration factors (BCF) values, based on dry weight, were below 1 for all metals. In most cases, BCF values decreased with increasing metal concentrations in the soil. From the heavily As-contaminated village in Samta, BCF values for As in ladies finger, potato, ash gourd, brinjal, green papaya, ghotkol and snake gourd were 0.001, 0.006, 0.006, 0.014, 0.030, 0.034 and 0.038, respectively. Considering the average daily intake of fresh vegetables per person per day is only 130 g, all the vegetables grown at Samta had Pb concentrations that would be a health hazard for human consumption. Although the total As in the vegetables was less than the recommended maximum intake of As, it still provides a significant additional source of As in the diet.

A tale of action, suspense and drama : Village Roadshow’s buy-back scheme

The experience of Village Roadshow, in its two failed attempts to have a share buy-back scheme approved by the Supreme Court, sounds a warning to companies and their legal advisers about the pitfalls in presentation of such schemes to shareholders.

"Join together, work together, for the common good - solidarity": village formation processes in the rural south of Laos

This article explores the concept of the solidary village in contemporary Laos. It argues that the "village" today is not a fixed, primordial entity, but a continually emergent formation resulting from numerous processes, including but not limited to modern state processes. The notion of "village" circulates in the ambiguous "common sense" pertaining to rural Laos, in the attitudes, expectations, representations, and regulated requirements of the rural, in what I term village formation projects. Case studies of "village formation projects" in one village in southern Laos illustrate not only the importance of the village concept, but also its indeterminacy and fluidity, and the ensuing difficulty of achieving the "solidarity" and cooperative donation required by poverty reduction policies.

Villages that never were : the museum village as a heritage genre

Villages of relocated buildings now constitute a phenomenon of the world's repertoire of heritage. They go by a multitude of names depending on particular inflection: open air museum, folk museum, living history museum, heritage village, museum village and so forth. 1 This paper reviews the context of the form of the genre's manifestation in Australia, where it is often known as the `pioneer village'. They are the fruit of a populist vision of national history which celebrates white rural settlement as its central theme. In practice, the villages manifest a deep commitment to collecting and saving old buildings as the meaningful construction of a favourite historical identity. But the generation that established Australia's villages has been overtaken. Today, the intersection of museum villages with the managerialist pressures of local economy enhancement and modern professional standards of heritage management challenge most villages' survival.

The global village: online cross-cultural communication and HRM

Purpose – The purpose of this paper is to examine relational and task dimension of online communication and the associated emotional experience.

Design/methodology/approach – This paper examines four categories of work outcomes: emotional experiences of work, work attitudes, work dynamics and work behaviours; and links each to the cross-cultural online communication context.

Findings – It was found that diversity-oriented HRM can reduce the cultural fault-lines betweenindividualist and collectivist (IC) cultures, and thereby positively moderate the relationship between cross-cultural online communication and affective, cognitive and behavioural outcomes.

Practical implications – Diversity-oriented HRM can capitalize on an organisation’s cultural diversity and avoid cross-cultural misunderstandings. In a more practical sense, the research purports that combined use of IC HRM practices can produce greater efficiency and effectiveness in
online communications worldwide.

Originality/value – The paper provides an insight into the potential implications of increased use of information technology on cross-cultural communication, and human resource management. The significance of diversity-oriented human resource management in managing these implications is also highlighted.

Village citizenship in China : a case study of Zhejiang

This paper aims to examine the idea and practice, as well as the implications, of village citizenship in China. It spells out the context and content of village citizenship, describes struggles for village status, and addresses the puzzling questions of why and how villagers seek to retain this status. It further examines the logic of how such struggles are leading to the establishment and improvement of village democratic institutions. The paradoxes and problems associated with village citizenship, and the significance of village citizenship for achieving meaningful citizenship are also explored.
