Geochemistry of well water and cardiovascular diseases in Sri Lanka

A survey carried out on the incidence of cardiovascular diseases in Sri Lanka in relation to the hardness of drinking water reveals that a correlation exists which is geographically related. This correlation however, cannot be considered as a causal relationship and other factors possibly exist that could also play a major role in the incidence of cardiovascular diseases, e.g. trace elements.

The environmental chemistry of rainwater in Sri Lanka

Rainwater samples collected from different parts of Sri Lanka have been analyzed for their chemical constituents. It was observed that except for minor occurrences, “acid‐rain” is still not prevalent in Sri Lanka. Based on the chemical composition, the rainwater of Sri Lanka has been classified chemically into eight different types, the most dominant being Ca/Mg—HCO3, Ca—Cl and non‐dominant cation—HCO3 types. The wet zone of Sri Lanka, particularly the areas around the central highlands, form a special zone in that a number of chemically different rainwater types can be found in these regions. In contrast, the dry zone of Sri Lanka receives four distinct types of rainwater and conform to geographical zones.

Construction linkages in a developing economy: the case of Sri Lanka

The importance of the construction industry stems from its strong linkages with other sectors of the economy. Despite the extensive research on input–output analysis and sectoral linkages of construction, a gap is found in the literature dealing with developing economies. The objective is to study the construction linkages in a developing economy using input–output tables compiled since the 1970s in Sri Lanka. Results show that the share of construction in gross national product and national income is lower in Sri Lanka than in developed countries. In Sri Lanka, the share of manufacturing in GNP declined while the share of services has increased with economic development. The backward linkage indicator ranges between 0.364 and 0.457 during the period of 1970–2000 while output multiplier ranges between 1.496 and 1.641 indicating the ‘pull effect’. The ‘push effect’ is found to be very insignificant. An aggregated sectoral analysis reveals high dependence of construction on manufacturing followed by services. The trend analysis shows an increasing dependence of construction on the services sector. The direct and total inputs from manufacturing and services have increased over time.

The environmental chemistry of Mahaweli river,Sri Lanka

The water pollution levels of Mahaweli River, the longest river in Sri Lanka, the basin of which covers one sixth of the Island, were monitored to probe the impacts of the urban environment in a developing country. It was observed the chemical quality is largely controlled by natural factors. From among the metals however, vanadium, zinc and copper showed higher concentrations. Pb and Cd showed a correlation co‐efficient of r = 0.58 for each other, and Co showed a highly significant correlation of r = 0.98 with Cu. The lack of correlation of Pb and Cd with the total dissolved solids (TDS) indicates an anthropogenic input of Pb and Cd into the aquatic environment. In general, the chemical quality of the water in the Mahaweli river is satisfactory for most purposes, none of the major dissolved constituents and nutrients exceeding the limit suggested by the WHO for potable water.     

Some problems associated with tube well programmes in Sri Lanka

The groundwater circulation is limited in Sri Lanka because nine tenth area of the island is underlain by metamorphic hard rocks which are generally very impermeable. Therefore to satisfy the water demand some other possibilities of water resources should be explored before starting a groundwater investigation programme for a given area. Preliminary data collection is very important to assess groundwater storage. But the required data are not freely available for any river basin. Geological informations and groundwater levels obtained from dug wells are necessary to get a general idea on its occurrence. The present construction methods of the dug wells do not facilitate to flow water freely. Sources of contaminations and errors in geophysical measurements are the other important problems arising during investigations. The design and construction of each well should be individually done to suit the heterogeneous nature of each location. But it would be difficult to conduct individual analysis because of the lack of laboratory facilities closer to the well sites. There are no acceptable scientific programmes for the future developments of groundwater in Sri Lanka. The main aim of the existing projects is to construct a certain number of tube wells (irrespective of the demand) for each area. The geoscientists have no choice to construct a tube well at the appropriate location due to the interference of some sociological problems in some areas. Therefore it is necessary to establish a Groundwater Research Institute in Sri Lanka.     

Housing and home-making in low-income urban settlements: Sri Lanka and Colombia

Enabling the making of home is central to the practices of housing, but constructing home is more than building adequate shelter. It is about establishing, nurturing and managing social relationships and bringing together spaces, objects and elements to represent and celebrate desired relationships, events and memories. Drawing on empirical data from Sri Lanka and Colombia, this paper examines in detail the practices of home-making in low-income settlements. By focussing on people’s conceptions of home and by identifying key social and societal practices, the paper offers insights into the processes of home-making among ordinary dwellers in developing countries and calls for culturally sensitive and holistic housing interventions which support and complement these processes.

Limits of the geological predictions constructing the samanalawewa pressure tunnel,Sri Lanka

The Samanalawewa Hydroelectric Power Plant in Sri Lanka consists out of a 110 m high dam, 5.5 km near surface pressure tunnel and a powerhouse equipped with two Francis turbines of 62 MW each. To explore the geological conditions for the pressure tunnel about 6500 m were drilled with a total of 97 boreholes. Additionally surface investigations and a geophysical program were realized in order to optimize the drilling campaign. Notwithstanding this very extensive field investigations important modifications in the design of the tunnel had to be made during construction. Consequently, the contractor claimed additional not foreseeable construction works. At least the question of the possible precision of geological prediction within reasonable economical limits had to be answered.

Estimating the environmental suitability of wall materials: preliminary results from Sri Lanka

Despite rapid increases in the building industry's contribution to resource depletion, waste generation and energy consumption, the creation of built environment remains vital to a country's economic development. This makes the building industry a prime candidate for sustainable development. Tools that help estimate the environmental suitability of building products can advance the cause of sustainable development.In this study, we estimate the environmental suitability of five of the most commonly used wall materials in Sri Lanka (brick, cement masonry unit, cabook, rubble AND wattle and daub). An “Environmental Suitability Index” is developed based on three parameters: embodied energy, life-cycle costs and re-usability. The possibility of using similar indices for other materials in Sri Lanka as well as elsewhere are explored.     

Environmental,economic and social analysis of materials for doors and windows in Sri Lanka

This paper compares the environmental, economic and social impacts of two types of doors and windows (elements), namely timber and aluminum taking into consideration the life cycle perspective. These elements are widely used for the buildings in Sri Lanka. Thus, it will help in the decision-making process when selecting materials for these elements. Major materials used for these elements are timber, brass, glass, paint, aluminum, rubber, steel and PVC boards. Environmental burdens associated with these materials are analyzed in terms of embodied energy, and environmental impacts that are relevant to Sri Lanka, such as global warming (GWP), acidification (ACP) and nutrient enrichment (NEP). Economic analysis is done using market prices of materials and affordability for those materials. Social concerns such as thermal comfort, good interior (aesthetics), ability to construct fast, and durability are analyzed based on the data collected through the questionnaires and also, interviews with the stakeholders of the buildings such as engineers, architects, building contractors and building users. It was found that timber elements are superior to aluminum elements in environmental scores (GWP, ACP and NEP). On economic score, also, timber elements are better. But on social score, aluminum elements are better than timber. It was also found that the higher the recycling percentage of aluminum, the higher the environmental favorability of the aluminum.
