Title

Occurrence of Fluoride in Ground Water of Patripal Panchayat in Balasore District, Orissa, India

Abstract

The Patripal Panchayat Balasore, District Odisha, India, has been recognised as a fluoride affected area. The survey indicates that many of the people in this region of Odisha have either dental or skeletal fluorosis. The high concentration of fluoride in the water resources in some localities such as in the Nuagan, Chakulia, Baharda, Kuanrpur of Patripal Panchayat are of great concern. A study has been carried out for the determination of fluoride in drinking water at various villages of Patripal Panchayat, Balasore District, Odisha. Fluoride was determined by using SPAND reagent and acid zirconium chloride by spectrophotometer at 570 nm. The value ranges from 0.6 mg/L to 5.83 mg/L. Most of the villages have higher concentration of fluoride than suggested by WHO and BIS and most of the people were affected by fluorosis like dental fluorosis or skeletal fluorosis. After the analysis of samples in this region, it was found that 70 percent of villagers are prone to fluorosis which caused by excess fluoride concentration in drinking water.

Ompok pabda (Hamilton-Buchanan, 1822): New Reports from Freshwater Environment of Tripura, India with a note on Length–Weight Relationship and Condition Factor (K)

Abstract

Ompok pabda (Hamilton-Buchanan, 1822) is a valid species. The present observation reports this species for the first time from freshwater environmental resources of Tripura, India. A new distributional record for this species was noticed from Gomoti, Muhuri and Feni rivers of Tripura. The data of the physico-chemical parameters of the studied freshwater environmental resource was highlighted. The length-weight relationship of this fish species was found to be W= 0.00759 L3.104. Here regression parameter b ranged from 2.81 to 3.32 (r2 > 0.90). The relative condition factor fluctuated from 1.032-1.372 with higher value during pre-monsoon.  During the pre-monsoon, the allometric coefficient b of the LWR was close to isometric value (b = 3.08) as well as allometric value (b = 2.87). Throughout monsoon period the data suggests negative allometric growth of Ompok pabda. The condition factor ranged from 0.672 to 0.744. The feeding intensity was found to be maximum during post-monsoon period. The diet composition indicated the highest ingestion of smaller fish followed by crustaceans as well as death and decayed matter. The present findings may be useful in conservation angle of vision and sustainable fisheries management viewpoints also.

Ompok pabda (Hamilton-Buchanan, 1822): An Endangered Catfish of Tripura, India: Reproductive Physiology Related to Freshwater Lotic Environment

Abstract

In aquaculture view point, knowledge of reproductive physiology of Ompok pabda (Hamilton-Buchanan, 1822) is important. To study this parameter live individuals are being sampled from lotic and freshwater environmental resources of Tripura, India such as Feni River, Muhuri River and Gomoti River and Rudrosagar wetland as well. During studies of reproductive physiology of this fish species some parameters such as gonado-somatic index (GSI), sex-ratio, fecundity, maturity stages, egg diameter etc. are being observed.  The studied fish population consists of as many as 93 males and 147 females.  The population is being dominated by the female always.  Maturity stage of Ompok pabda develops spawning period at some period of monsoon during May to August. The length at first maturity of female is 17.0 cm, while it is 16.3 cm in male. Maximum gonado-somatic index (GSI) % for male has been 2.195 and it is 15.582 for female. First maturity stage is noticed during May-June and peak spawning period in June-July. The egg attains greater diameter during June to early-August. At peak spawning period fecundity is varied from 2190 to 41552 eggs/individual. Some potential environmental features of the studied lotic ecosystems are being analyzed during the period of fish sampling.

Status of Occupational Health and Safety in Brick Kiln Industries at Hatter Industrial Estate Haripur, Pakistan

Abstract

This study was carried out with an aim, to explore Occupational Health & Safety (OH&S) status of the workers in Brick Kilns (BKs) at Hatter Industrial Estate Haripur (Khyber Pakhtunkhwa, Pakistan) in relation to the current health and safety laws. It is a legal and moral requirement that owners of the Kilns should provide accident free working environments and basic welfare facilities for their workforce but Pakistan has a poor health & safety status; due to in-adequate medical facilities, illiterate workforce and lack of reliable data on the occupational diseases, injuries and accidents. Workers are exposed to high level of hazards in all sectors i.e. construction, mining industry and agriculture. Brick making is one of the leading sector in construction industry; where workers are mostly from deprived sectors of society; with low income and where the whole family is involved as one unit. OH&S Conditions in the BKs of the study areas at Hatter Industrial Estate were extremely poor. Their living and the working conditions were highly poor, both legally as well as morally. They work for 12-14 hours without any overtime. Their income was not enough to full-fill their basic needs. Provision of Personnel Protective Equipments (PPE); a last line of defence for workers and welfare facilities were not made at all the BKs of the study area. Some of the major contributing factors to the poor health and safety status of the workforce are poor implementation of the health and safety laws with dangerous, unsafe and polluted working environment. In this study, we tried to draw some guidelines for the betterment of OH&S situations in BKs.

Title

Comparative Assessment of Microbial Biomass and Soil Enzyme Activities as Potential Indicators of Soil Quality in Different Mine Spoil, Orissa

Abstract

Mining activities have drastically alters the soil subsystem in mining areas and an assessment of these changes is essential to determine soil quality. There is growing recognition for the need to develop sensitive indicators of soil quality in promoting appropriate soil management strategies for long-term sustainability of terrestrial ecosystems. The variation in organic Carbon, total Nitrogen, available Phosphorus, Microbial Biomass (MB) and enzyme activities among five different mines (i.e. coal, iron, gypsum, graphite, aluminium) overburden spoils of Orissa, India, were studied along with the forest soil as control. In the present investigation, microbial parameters (microbial biomass C, N, P) and microbial activity (as an index of soil enzymes i.e. amylase, invertase, protease and dehydrogenase) are considered to be indicative measures of soil quality. Comparative analysis of enzyme activities revealed that there was significantly (p<0.001) higher amylase, invertase, protease and dehydrogenase activity in forest soil as compared to nutrient deficient situation (mine spoil). The variation in microbial biomass and enzyme activities correlated very well with land degradation, attributable to reduction in C, N and P in mine spoil as compared to forest soil. The higher microbial biomass and enzyme activities in forest soil as compared to disturbed mine overburden sites shows the effect of land use management, soil sustainability and consequently ecosystem functioning.
