Occupational Health Hazards of Ship Breaking Workers in Sitakunda, Bangladesh

2024-04-21T15:28:39+0530

Poor occupational health and safety at the expense of many lives and livelihoods that hinder economic growth in ship breaking industry of Bangladesh. Poor and unsafe working conditions are both causes and consequences of extreme poverty with life risk. Both reinforce each other negatively. The significance of occupational health and safety is particularly strong in countries like Bangladesh where it is not addressed or explored. The main problems mentioned by the workers are low wages, irregular wages, overtime, lack of medical facilities, dirty working environment, inadequate modern equipment, lack of recreation, lack of job security.41% workers job are contract type, 29% have no training facility, 53% not use safety equipment, 48% feel unsafe this job. The workers of this industry are exposed to an extremely risky and toxic working environment which makes them vulnerable to physical and psychological disorder as well as to accidental injury and deaths. Still, workers embrace these risks with very poor wages. So occupational health and safety in this industry of Bangladesh should be a higher priority in discussions of extreme poverty, its consequences and a sustainable development should be taken to minimize the impacts of ship breaking activities in coastal zone.

Pesticide effects of Organic fertilizer on Rhizophora seedlings

Insects impose widespread damage to Mangrove leaves and in severe cases even kill the Mangrove trees. Controlling of them through natural method is necessary because they are eco-friendly. The present study deals with Pesticide effect of Panchagavya and Jeevamrutham that intensify plant growth and ameliorate soil health. This study carried on period of March to May 2021 in Pichavaram, Chidambaram, Tamil Nadu, India. These two organic fertilizers were prepared through the fermentation process of cow products milk, curd, ghee, urine and dung. Jeevamrutham is more effective when the plant is in its early stage of growth. Panchagavya is an effective after the first stages of growth. Both fertilizers were reported in efficient antibacterial effect. Conclusion of this study, we reported both fertilizers them as the efficient natural plant growth stimulants. Moreover, the Pesticide activity of fertilizers was studied in Mangrove seedlings against the dangerous pests and its antibacterial activity was also scrutinized.

2024-05-25T22:16:42+0530

This article examines the challenges confronting Basmati rice cultivation in Dehradun, with a focus on climate change, land use shifts, market dynamics, and pest infestations. Analyzing the decline in Basmati rice production, the study employs remote sensing, GIS, and climate data analysis to identify the complex web of issues. Results highlight climate-induced variations, changing land use patterns, market dynamics, and pest-related threats. The article concludes by emphasizing a knowledge gap, especially among the youth, and highlights the need for interventions to make agriculture more appealing and sustainable. Collaborative efforts and innovative solutions are crucial for revitalizing Basmati rice cultivation in Dehradun, ensuring a resilient agricultural future.

Microbial Load Induced Degradation of Ithikkara River in Kollam District, Kerala

2024-06-18T20:48:01+0530

Water quality convey the health of ecosystems, safety of human contact, extent of water pollution and conditions of drinking water. One of the most important factors of water pollution is the microbial contamination; especially with pathogenic microorganisms. In this study, the physico-chemical and microbiological examination of Ithikkara River was carried out to ascertain their suitability for consumption and presence of microorganisms that could cause water-borne diseases. Ithikkara River is a 56 km long river and it originates from the Kulathupuzha in the Western Ghats and flows through the Kollam district, finally emptying into Paravur Lake. The village of Ithikkara is located on the river, 15 km from the port of Kollam. The river also flows through the settlements of Chathannoor and Pooyappally. The objectives of the study was to investigate the seasonal variations of physico-chemical parameters and microbiological analysis such as total microbial count, total coliform count and E.coli count. For assessment of water quality the areas such as Alummukku , Anapuzhakkal, Kuzhiyam were selected and investigated .Water samples were collected from the study area and the physico-chemical parameters were analyzed with respect to the seasons following standard methods.The study indicates that there is a pronounced variation of most of the water quality parameters with variations in seasons. High alkaline nature was observed in site 2. It may be due to the discharge of food wastes to the river. The rate of carbon dioxide in all the three stations increases according to seasonal changes from pre monsoon to post monsoon and dissolved oxygen decreases from pre monsoon to post monsoon. The study shows that high E. coli were observed in station 3. During the drought period, animals and humans located near the river, depend mostly on rivers for bathing and other purposes. It may be causing faecal contamination of river. The findings from the present study provide a better understanding about the current situation of the river and reminds the necessity for rejuvenating it. Thus, the study suggests that the river water needs urgent measures to control pollution and also to aware the local people to properly treat the water before using it.

Assessment of Water Quality in Amgaon’s Lakes: Implications for Beautification and Recreation

2024-05-31T06:37:06+0530

Evaluation of water quality of three lakes viz. Matabodi, Padampur and Risama in Amgaon town, Gondia district, Maharashtra, India under the 'Amrut Sarovar' scheme, focusing on their suitability for beautification and recreational purposes.The lakes exhibit compromised water quality due to various contaminants. The presence of free ammonia found to be 3.9 to 4.5 mg/L which exceeds permissible limits as defined by CPCB standards. The lakes also show contamination with total coliforms and fecal coliforms. Phytoplankton analysis reveals the prevalence of cyanobacteria species, which can produce harmful toxins. The phytoplankton diversity index suggests moderately polluted waters. The Shannon Wiener Diversity Index of 1.4 to 2.1 and Palmer Pollution Index of 14, 7 and 6 indicating mildly to moderately polluted water. Zooplankton assessment shows the presence of rotifers and daphnia indicating certain ecological disturbances. Further efforts are required to restore and maintain the water quality of these lakes for beautification and recreation.
