The importance of training for environmental management

Conclusion I wish to conclude as I began, with a quotation from a newspaper on the potential damage and the attendant costs of not applying sound environmental management: The Guardian, Wednesday, 5 October 1983: “The Shell Oil Company which admitted yesterday that it had allowed dangerous pesticides to escape near Denver, Colorado has received a demand from the US Army for $1 8 billion to help to stop pollution from reaching the city ... Shell and the US Army research, which includes experiments with nerve gas, may have caused far more serious pollution in the area.” The need for sustainable development and for training in environmental management in Third World countries, should ensure that reports on environmental damage, such as the one above, do not become a common occurrence in developing countries in the next decade or hopefully forever after. This paper was presented at the conference “The Environmental Dimension in World Development, the contribution that British Companies can make”, organized by the Centre for World Development Education, London, UK, during October 1983. Dr Jose I. Furtado is Professor of Zoology in Malaysia, and is seconded as Science Adviser with the Commonwealth Secretariat in London.     

Assessment of El-Salaam underground water for poultry use

Water quality for 13 wells in El-Salaam, in a new city near Cairo, has been investigated. Those wells were dug specifically to provide water for a company specializing in broiler poultry production. The water was analyzed for the following bacteriological parameters: total bacterial counts (10²–10⁴), total coliforms (<1?10²), fecal coliforms (<1?10²) fecal streptococci (<1?10³), aerobic spore formers (10²–10⁴) and total counts for Clostridia (<1?10³) per 100 mL. Chemical parameters such as pH, sulphate, alkalinity, hardness, and pesticides indicate that the water is unacceptable for poultry production. This study illustrates the need for monitoring and maintaining the integrity of groundwater sources at El-Salaam.     

The Contribution by the Study of the Algae Forms (Phytoplankton and Periphyton) as Integrators of Physicochemical and Microbiological Data in the Varenna Stream

Physico-chemical, microbiological, ichthyotoxicological conditions and microalgae of Varenna stream were studied in samples taken in 12 collecting stations. The data reported indicate a marked deterioration proceeding downstream e.g. an increase of bacterial population, concentration of suspended solids, COD and variations in the composition and abundance of phytoplankton and periphyton.     

Metal contamination of drinking water from corrosion of distribution pipes

The objectives of this study were to evaluate metal contamination of drinking water resulting from the corrosion of distribution pipes and its significance to human health. A community in Dhahran, which is served from its own desalination facilities, was chosen for this study. About 150 drinking water samples were collected and analyzed for metal concentrations using an inductively coupled argon plasma analyzer. It was found that copper, iron and zinc in the drinking water increased during its transportation from the desalination plant to the consumers. This increase was related to the length and material of distribution pipes. Concentrations of copper and zinc were increased during overnight storage of water in the appliances. Metal concentrations found in this study are discussed with reference to human health.     

New morphological characteristic of Xyrichtys novacula (Pisces: Labridae) from the Adriatic Sea

In 1983 curred horns were detected in the rare Adriatic Sea fish Xyrichtys novacula (Linnaeus, 1758). Their dimensions and histological structures have been investigated. This observation, compared with previous occurrences, suggested the existence of heteromorphism within this species.     

Dynamics of skeleton formation in the Lake Baikal sponge Lubomirskia baicalensis. Part II. Molecular biological studies

In a preceding study it has been reported that the freshwater sponge Lubomirskia baicalensis, living in Lake Baikal (East Siberia), is composed of spicules forming a characteristic pattern which follows radiate accretive growth. Here we report that the spicules are synthesized by the enzyme silicatein, a protein which is related to cathepsin L. The cDNAs for silicatein and the related cathepsin L were isolated and used as probes to show that the mRNA levels of silicatein in the bases of the spicule skeleton of the animals are low, while the mRNA level of cathepsin L in this region exceeds that of the growing zone. This is the first comprehensive study on the importance of the axial filament/silicatein as an essential structural and functional component determining the growth and stability of demosponge spicules.Note: Sequences from Lubomirskia baicalensis have been deposited in the EMBL/GenBank; cDNAs for the putative silicatein (LBSILICA) are deposited under the accession no. AJ786771 and for cathepsin L (LBCATL) under the accession no. AJ786770.
