“…The higher concentration of Pb and Zn in various samples is reported due to local contamination from Pb and Zn batteries [21], since there is no facility for proper disposal of the batteries in the valley. In addition to road traffic and transport [48], metallic building roofs and gutters are also reported to be amongst the main sources of zinc contamination of surface waters [49]. These causes are also important factors contributing to higher levels of Pb and Zn in drinking water samples in the Pearl Valley.…”

The aim of this study was to assess trace metal contamination of drinking water in the Pearl Valley, Azad Jammu and Kashmir (Pakistan). The objectives were to determine physical properties and the dissolved concentration of five trace metals, i. e., lead, copper, nickel, zinc, and manganese, in drinking water samples collected from various sites of municipal water supply, natural water springs and wells in the valley. Concentrations of the metals in the water samples were determined by flame atomic absorption spectrometry. Results showed physical parameters, i. e., appearance, taste and odor within acceptable limits and pH was between 5.5 and 7.0. The observed concentrations of the metals varied between sources of water samples and between sampling sites. Maximum dissolved concentration observed was 4.7 mg/L for Pb and Mn, 4.6 mg/L for Zn, 2.9 mg/L for Ni and 2.8 mg/L for Cu. The observed concentrations of the metals were compared with the World Health Organization's guideline values for drinking water. Overall, the quality of water samples taken from the water springs at Mutyal Mara and Bonjosa was good; however, the water quality was unsuitable for drinking in Kiraki, Kharick, and Pothi Bala localities particularly. Finally, the authors discuss possible causes for increased concentrations of the trace metals in drinking water in the study area.

“…Metal contaminants, which are stored in sediments, may have a greater influence on biological uptake than those in waters, particularly in the case of benthic faunas as reported by Breward et al, 1998. Ramessur, et al, 2002, studied the concentration of lead, chromium and zinc in sediment of an urbanized river of Mauritius. The mean concentration of Cr and Zn are (105+ 30 mg kg -1 ), (167 + 30 mg kg -1 ) respectively in the sediments along St. Louis river.…”

Sediment serves as a reservoir for heavy metals and therefore, deserves special consideration in the planning and design of aquatic pollution research studies. An undisturbed sediment column contains a historical record of geo chemical characteristi cs. It will allow an investigator to evaluate geo chemical changes over time, and possibly, to establish baseline levels against which current conditions can be compared and contrasted. Metals may be mobilized as a result of natural processes (e.g., weathering and erosion of geo chemical formations) as well as by anthropogenic activity. In the mobilization process, trace elements may be absorbed by days, can complex with organic compounds or may co-precipitate with oxide and hydroxides. Indeed sediment shows a high capacity to accumulate and integrate on time.

“…According to previous studies of coral reef eutrophication, the indicators of eutrophication in coral reefs should be the threshold values of eutrophication, with the concentration of inorganic nitrogen around 1 μM and the concentration of inorganic phosphorus (PO4-P) around 0.2-0.3 μM [8]. [phosphate] ratio in the wells and seepage chambers indicated a high input of nitrate in the Flic en Flac coastal area which may be of agriculture origin and fertilizers [9][10][11].The steady rise in the number of vehicles using unleaded petrol since the 1980s and has also contributed to water pollution to some extent [12][13][14][15][16][17]. Lead content of freshwater systems near areas exposed to a high flow of motor vehicles was found to be higher than those less exposed to such conditions [18].…”

“…Studies have showed that estuaries are particularly vulnerable to nutrient over-enrichment and trace metal contamination hence highlighting the need to monitor these aspects of pollution in estuarine regions [25][26][27]. The major source of dissolved phosphate in lagoons may come from runoff of phosphate fertilizers that leach from sugarcane plantations into groundwater, which feeds the wetlands and the lagoons.…”

The National Climate Change Adaptation Policy (NCCAPF) enabling framework in Mauritius has been designed to address key barriers such as lack of financing options, lack of institutional framework and low levels of adaptation technology transfer and aims to integrate and mainstream climate change into core development policies, strategies and plans of Mauritius The Capability Approach would ensure that social arrangements target at increasing people's capabilities and would consider indicators that reflect the importance of assessing the quality of processes rather than simply outcomes of policies and the significance of measures to enhance the ownership and participation of local communities in the management of their natural resources under integrated coastal zone management ICZM. The overall objective should be to develop climate compatible projects for vulnerable coastal regions. The paper reviews measures to strengthen coastal zone management facing climate change and natural disasters and to further improve natural disaster risk management in Mauritius in line with climate compatible development schemes and effective integrated coastal zone management of small islands states under the DPSIR Framework.
