摘要Objective:To determine common physico-chemical parameters of coastal water. Methods:Physicochemical properties of water were determined according to the standards of the American Public Health Association. Generally, all those parameters were recorded a small variation between stations. The variation in physico-chemical parameters like salinity, temperature, dissolved oxygen and pH at Gwadar (Coastal water of Balochistan) were recorded. Results:The range of air temperature of coastal water of Balochistan during 2004 and 2006 varies from 25oCto 37oC, water temperature ranged from 15.00oC to 33.00oC, pH ranged from 7.08 to 8.95, salinity ranged from 37.4‰ to 41.3‰and dissolved oxygen ranged from 5.32 to 8.67 mg/L. Conclusions:Results showed that these parameters of Balochistan coast of Pakistan is not dangerous for marine habitat and the use of these parameters in monitoring programs to assess ecosystem health has the potential to inform the general public and decision-makers about the state of the coastal ecosystems. To save this vital important habitat, the government agencies and scientists should work with proper attention.
