I. Introduction Inland bodies of waters of every form, composition, altitude and latitude are populated with organisms, both plants and animals. The quantity, distribution, and diversity of these organisms differ greatly in various waters and are primarily determined by its immediate environment and the factors that characterize it (Soo, et. al., 1997). The animal components of these waters, particularly lakes, are represented mostly by zooplankton in extremely great numbers so that an evaluation of their population dynamics, and certain important environmental characteristics that influence these dynamics, is fundamental to formulations of the productivity of these aquatic bodies (Reazo, 2001).
VII. After the completion of test, remove the cap of the comparator and discard the water into the soil. 8. Biological test : This test is performed to check the presence of living organisms in the water body such as algae, bacteria, plankton etc. This is done with the help of microscope.
The efforts to establish small, medium and large-scale irrigation schemes in the study area are constrained by a number of uncertainties. Firstly, stream flows of the rivers are not known. Secondly, suitable areas of the watershed have not been identified and the water requirements of crops commonly grown in the watershed is not estimated. In Temicha watershed from time to time increasing of deforestation, expansion of residential area and increasing of agricultural land which aggravates the land cover change of the watershed. This continuous land cover change has influenced the water balance of the watershed by changing the magnitude and pattern or the sequence of the components of stream flow that are surface runoff and ground water flow, which results increasing the extent of water management problem.
1. INTRODUCTION Water is used for production, construction and consumption amongst other uses. Water that meets the required quality sustains lives, promotes good public health and sustainable environment (National resources defense council, 2014)). Most of the world water resources lack basic protection from factory, industries and other activities that pollute the water; which leads to contamination of drinking water, habitat degradation and beach closures. Polluted water sources threaten life span and wellbeing by destabilizing the ecosystem.
RAINWATER CONDITION IN INDONESIA Rainwater is water that evaporates due to the heat and the condensation process to form larger drops of water then falls back to the earth 's surface. At the form of water vapor there is a transport process of water vapor by the wind towards certain areas that will occur rain . At the time of the transport process the water vapor mixed and dissolved with oxygen, nitrogen, carbon dioxide, dust, and other compounds so that rainwater can be easily contaminated by dust, bacteria, and various compounds contained in the air. The environmental conditions affected the rainwater quality. Rainwater contains more gas than groundwater, especially the content of CO2 and O2.
Examples of these are the melting of the ice bergs at the poles and huge droughts such as el Niño. How would this effect wetlands? Due to the increase in water volumes there is a sudden increase in water in wetlands this covers many species of plants and drowns them. The drought causes wetlands to dry out and draw out most of the nutrients of the land. Due to rapid urban growth the demand to remove the wetlands by human means is very high.
Ground water is enormously varied in chemical composition and the factors controlling the composition includes physical, chemical and biological processes. Hutchinson (1957) defined fresh water as “dilute solutions of alkali and alkaline earth bicarbonate and carbonate, sulfate and chloride with available quantity of largely un-dissociated silicic acid which often is present in excess of sulfate and chloride”. There are also a number of minor elements in true solution, some of them being of great biological interest and a variety of colloidal materials, both inorganic and organic. Quantitative measurements of these parameters in natural water serve as source to address the basic environmental problems. Adopting suitable analytical methods
To know the effect of artificial acid rain into aquatic plant 3. To differentiate the effects of artificial acid rain on aquatic plant, according to the kind of water used Scope and Delimitations This study will mainly focus on the effect on the quality of water on aquatic plant during acid rain. It does not include any data about other aquatic organisms/animals/plants except for the duckweed. This study will be conducted beside the Pasig River for the collection of the plant. It is advised that the person who will conduct the experiment should use proper sanitary equipments like gloves and mask.
Water is a vital substance, as it is very essential for natural life (Lewandowska et al., 2000). An undesirable change in the physical, chemical or biological characteristics of water that will harmfully affect human life are known as water pollution (Singer, S. 1970; Akman et al., 2000; Sathyanarayanan, 2007). The aquatic ecosystem are directly or indirectly affected by pollution (Kosygin et al., 2007). Water body must be safe and free of risk factors. Risk factors related to water pollution, can be divided into two basic types: chemical and biological pollutants.
The effects of fisheries and excessive exploitation of the top predators and herbivores of the marine food web are conspicuously seen in the extinctions of sharks, turtles, whales, and other marine organisms. Statistics suggest that humans are currently exploiting over 400 species as food resources from the marine ecosystem. Exploitation of marine biodiversity is far less regulated by international conventions than on land and continuous advancements in technology is also aiding such deplorable actions. Global climate change has consequently caused an unprecedented mass movement of species to temperate regions near the two poles. Constant acidification of the ocean reduced the pH level of sea water and therefore buffered myriad of organisms from properly carrying out biological processes necessary for their survival.
