In texture silty sand at summer indicate low fluvial and in monsoon sand, silt and clay have indicate fluvial may high transportation so remove the finer particles and also coarser only deposited. Organic matter versus grain sizes represent only silt and clay content bounded with organic matter in monsoon than summer....
As per municipal acts governing the local bodies in the country, it is an obligatory duty of municipal authorities in the country to keep cities/towns clean and provide a good quality of life to the citizens. However, the services provided by the municipal authorities are outdated and very inefficient. Domestic, commercial, biomedical and variety of toxic and domestic hazardous wastes are generally disposed of by the citizens on the streets, drains, open spaces, water bodies etc., causing serious problems of health and environment. Problems of solid waste management are growing with rapid urbanization and change in the lifestyle of the people. The situation is becoming critical with the passage of time. The research aims to critically assess the current scenario of Municipal Solid Waste Management (MSWM) system and studying feasibility for technological alternatives based on case study approach....
The diminishing supply of petroleum along with the pollution caused due to the non-biodegradability of petroleum-based plastics has led to an increased interest in the field of biodegradable plastics. This paper endeavours to study a novel method for the production of biopolymers using waste banana peels, potato starch and corn-starch. The study also concentrates on analysing the properties of plastics concerning its tensile strength, boiling point, temperature sensitivity, coldness and flame tests. Among the three resources, production of biopolymers using the banana peels found be good. Further extensive and detailed studies required for further multiple application of these biodegradable plastic....
Research on jellyfish has necessarily increased in the new millennium due to greater contact with humans. The jellyfish are once considered as a menace by the fishermen folk but has recently attracted the attention of sea food exporters. Since this kind of work is not been carried out so far in Tranquebar, Southeast coast of India and considering all the above facts the present study was undertaken to have an inventory list of available jellyfish in Tranquebar and Kottucherry. The present study was carryout in the ecological parameters like rainfall, temperature, dissolved oxygen, salinity and pH of both Tranquebar and Kottucherry. Population density of jellyfish and to find out the species diversity, richness, evenness in the both the stations and to compare the outcome of the results. Cyanea Capillata, Crambionella stuhlamanni, Chrysaora quinquecirrha and Acromitus flagellates were recorded in the present study. Cyanea capillata species showed highest population density during Jan. 2017ââ?¬â?? Mar. 2017. Species diversity index (Hââ?¬â?¢) varied from 1.50 to 1.92. Higher species richness 0.69 was observed during postmonsoon and minimum richness 1.44 was observed during monsoon. Species evenness index (Jââ?¬â?¢) varied from 0.94 to 0.98 in Station 1....
The present investigation carries a first report of goose barnacles from Tranquebar coastal water, Tamil Nadu. Availability of barnacles was maximum than mussels and Oyster. Lepas anserifera was the prevalent macro fouler encountered in our coastal area. The rapid growth of macro fouling community has providing an alarming signal of its capacity to cause potential biodiversity losses and ecosystem damages in the coastal area. Hence, an urgent attention must be taken to control the macro fouling community in the coastal area....
The river water quality monitoring is most vital aspect for various uses. Diatoms are an ecologically important group in most aquatic ecosystems but are often ignored as indicators of river environment change. Diatoms are used as bio-indicators to assess the water quality of surface waters. Diatoms are used as bio-indicators to assess the water quality of surface waters. Sixty (60) species belonging to 21 genera are recorded from cauvery river. Water samples are assessed by analyzing the various physico-chemical parameters, such as pH, electrical conductivity (μs/cm), dissolved solid (mg/l), biochemical oxygen demand (BOD) (mg/l), calcium (Ca) (mg/l), magnesium (Mg) (mg/l), sodium (Na) (mg/l), potassium (K) (mg/l), chloride (Cl) (mg/l), bicarbonate (HCO3) (mg/l) and sulphate (SO4) (mg/l). These 8 parameters are considered to compute the water quality index. The results of the present study on diatom assemblages in cauvery river at siluvampalayam and koneripatti indicates moderate pollution, while at peramachipalayam, kottampatty, sanyasipatti and bhavani shows high level of pollution. The water quality index reveals that water of river cauvery to be unpolluted in the upstream of the city and unfit for human consumption towards the downstream at bhavani town. The values of DO and BOD levels indicate the absence of major organic pollution sources. In the present study an attempt has been made to evaluate the applicability of diatom based indices for water quality assessment in cauvery river in part of Tamil Nadu. The results of the present study shows that the Cauvery river water is not polluted in mettur area whereas it is highly polluted near bhavani area. All results are compared with national river water quality standards....
Various physico-chemical characteristics of the halali reservoir located near Bhopal were studied in the three season summer, rainy and winter of 2010-2011. Ecological parameters like dissolved oxygen (DO), pH, nitrate, phosphate and other physico-chemical parameter were analyzed and compared with the water quality standard of Bureau of Indian Standard (BIS) and Central and the State Pollution Control Board (PCB) limits to assess the best designated use. Attempts were made to study and analyze the physico-chemical characteristics of the water. All physic- chemical parameters give a picture of quality parameter in pond water of the Halali. By observing the result it can be concluded that the parameters which were taken for study the water quality are below the pollution level for ground water which satisfy the requirement for the use of various purposes like domestic, agricultural, industrial, aquaculture etc....
The present paper deals with the study of diatoms as indicators of water quality in yercaud lake, Salem district, Tamil Nadu, South India. Forty macrophytes samples and water samples are collected from yercaud lake in pre and post monsoon during 2011-13 and forty two (42) diatom species are recorded from these samples. Among the diatom species, a limited number of them (Amphora ovalis, Bacillaria paxillifer, Cyclotella meneghiniana, Cymbella tumida, Eunotia curvate, Fragilaria intermedia, Gomphonema lanceolatum, G. parvulum, G. undulatum, Nitzschia palea, Synedra ulna) are recorded throughout the year, while the diatom species such as Cyclotella meneghiniana, Gomphonema parvulum, G. undulatum, Navicula mutica, Nitzschia sigma, N. microcephala, N. palea, Pinnularia acrosphaeria, Surirella linearis and Synedra ulna are distributed in different locations of the lake. The physicochemical parameters such as temperature (°C), total dissolved solids (TDS), electrical conductivity (EC) (µs/cm), pH, total alkalinity (TA) (mg/l), salinity (ppm), calcium hardness (CH) (mg/l), magnesium hardness (MH) (mg/l), total hardness (TH) (mg/l) and total solids (TS) (mg/l) are analysed at TWAD board laboratory Salem to understand the water quality. The total diatom density showed significant positive relationship with respect to electrical conductivity (EC) and total dissolved solids (TDS) and significant positive correlation with chemical oxygen demand (COD). The analyses of pH, conductance, alkalinity and hardness levels indicate the moderate quality of water in yercaud lake. The values of DO, BOD and COD levels are very low indicating the absence of major organic pollution. The present study records the abundance of pollution tolerant species during pre-monsoon period due to the merger of sewage in yercaud lake....
