Water is the most abundant and non-renewable resource in the earth, which play an important role in all living organisms. A study on physiochemical parameters of Manur, Vallanadu and Sundarapandiapatinam ponds from Tirunelveli, Thootukudi and Ramanathapuram districts of Tamil Nadu, India, has addressed the seasonal changes. During the month of January to April samples from Manur was chemically portable, Vallanadu sample was physically portable, Sundarapandiapatinam samples were physically and chemically not portable. During the month of May to August Vallanadu and Manur samples were portable by its physical and chemical examination, Sundarapandiapatinam samples were non portable by its physiochemical property. September to December the samples from all the three ponds were non portable because of exceeding the permissible limit. All the samples were bacteriologically unsafe in nature because of its microbial contamination. This implies the water bodies are not fit for domestic and drinking purpose, thus proper management has to be done by the society and implement government guidelines to save the natural resources from manmade activities.

Sensory quality of peach during ripening to assess the best state for consumption was analysed. Physical and chemical parameters commonly used for establishing the commercial quality of this fruit were also determined: Soluble solids, acidity, sugars, organic acids, chlorophyll, carotenoids, resistance to compression and to penetration and colour. Relationships among these parameters and sensory characteristics were also analysed. A panel of eight trained assessors evaluated intensities of 12 sensory attributes (1 for odour, 2 for colour, 4 for flavour and 5 for texture). The sensory attributes selected allowed the description of perceivable differences between peaches of different degrees of maturity, although the variation in intensity of the attributes followed different trends. Colour intensity increased and acidity, firmness and crispness decreased significantly with ripening. Intensity of flavour, sweetness and fruitiness increased significantly from the under-ripe to semi-ripe states, and then decreased on reaching ripeness. It can be concluded that the most suitable time for harvesting and consumption of this peach variety was the state described herein as semi-ripe, and that a high correlation existed between colour intensity and hardness and the instrumental measurements of colour and texture.

The present study deals with the statistical analysis of physico-chemical parameters and cyanophycean members of two pond water quality of Chidambaram, Cuddalore district (Tamil Nadu). The qualities of pond water were analyzed for six months. Eleven important parameters were included in statistical analysis. The qualities of pond water have been assessed by calculating mean, standard deviation and correlation coefficient. Correlation studies of hydrobiology with physico-chemical parameters revealed that the relationship between phytoplankton density in general and that of the specific groups are highly complex and often controlled by interactions of different factors. In the both pond water the correlation coefficient test revealed that cyanophycean members positively correlated with temperature, pH, CO2, alkalinity, hardness, nitrate, BOD and COD at 1 % and 5 % level significant, where as it is negatively correlated with acidity and dissolved oxygen. In the present study it can be concluded that the cyanophycean members are highly tolerant organisms. They prefer to grow at higher temperatures and in highly alkaline, BOD and COD waters. Hence they can with stand high levels of contaminated waters of Thillai Kali Kovil pond, when compared to Ilamiyakkinar Kovil pond.

Twenty four (24) adult Nigerian local cocks comprising 8 normal, 8 frizzle and 8 naked-neck were subjected to two ejaculations per week for seven weeks in each season (early rain, lale rain, early dry and late dry seasons) using the massage technique. Ejaculates were subjected to both physical and chemical evaluations. Results showed a significant (P<0.01) seasonal effects between phenotypes in reaction time. In all the seasons, naked-neck and frizzle cocks had higher (P<0.01) ejaculate volume, sperm motility and total sperm than normal cocks. A highly significant (P<0.01) phenotype by season interaction was observed with naked-neck producing better quality ejaculates during the dry season when compared to other phenotypes. Significant (P<0.05) differences were noted in the percent abnormal sperm among the seasons. There were no significant season by phenotype interactions (P>0.05) in most of the chemical parameters (Na+1, K+1, Ca2+, Mg2+, and total protein) evaluated. However, a gradual increase in seminal protein was observed among the phenotypes with a peak during late dry season. The cations (particularly sodium, potassium and calcium) and chloride constituents of ejaculates were significantly lower during the late dry season than at most other seasons. From these results it was concluded that the naked-neck and frizzle cocks appear superior to the normal cocks in semen output and quality under the humid tropical environment.

Human beings require potable water for drinking to keep them healthy. Clean, safe and adequate fresh water is vital to the survival of all living organisms. Drinking water affects the health of human beings due to the presence of various dissolved chemical constituents. Problems arising out of chemical constituents in drinking water are different from the problems of microbial contamination. Therefore, consumers should have at least minimum knowledge on quality of drinking water. People across the world depend on ground water for drinking. Ground water is a major source, so based on the importance of the matter; a research topic is taken up on the assessment of quality of groundwater in the selected areas of villages in Veeraghattam and Palakonda Mandals of Srikakulam District, Andhra Pradesh. This preliminary study assessed the quality of physical and chemical characteristic properties of underground water in the selected locations of 40 villages in Veeraghattam and 39 villages in Palakonda Mandals of Srikakulam District. Some physico chemical characteristic parameters are estimated in the samples and the results obtained are compared with the available standard values such as WHO and BIS.

Groundwater is significant in satisfying domestic and agricultural needs.Besides scarcity, the groundwater resource is degrading drastically around the world. The Ambuliyar watershed falling in parts of Tamil Nadu also faces similar problems. To decipher the quality degradation, pre-monsoon and post-monsoon data on various physical and chemical parameters was collected for 29 wells for the year 2014 from Public Works Department. Spatial maps were generated on the above geochemical parameters and categorized into five classes using GIS software. Weights were assigned for each parameter based on their relative importance in with each other parameters. Finally, quality index map was generated by integrating them, and subsequently their aerial extent in monsoons was worked out. During the post-monsoon period, 18% of the study area represents “excellent”, 46% “good”, 25% shows “moderate” and 11% shows “poor” quality. While during pre-monsoon period, 34% of the area exhibits “excellent”, 43% “ moderate”, and the remaining 23% of “poor”.
