Feminist Mining: A Step Towards Sustainable Mininig in India

Economic growth and development with least harm to the environment is one of the biggest challenges for the human. Mining which is considered to be the most inherently unsustainable industry, is at the same time, plays key role in the development process in India and across Globe. It occupy primary position in the supply chain, contributing to the foreign direct investment, exports, government taxes, GDP (National Income) and provide huge labour employment. This paper studies industrial elimination of women, prolong industrial patriarchy, impetuous production, rising demand pressure has added to the quadrupling problems of land degradation, disposal of over burden/waste discharge, deforestation, pollution(air, water, and noise), and damage to forest flora and fauna, occupational health hazards and extreme global environmental damage in a rapid, continuous manner. These continuous and multi-layered problems are giving us reason to re-visioning steps, where we went wrong. Theoretical foundation of eco-feminism traces that negligence and suppression of women in general and in the mining industry, is one of the probable cause that hit environment fiercely. With this in mind, this paper suggests theory of eco-feminism into male centric mining industry as a perspective which is more likely to lead to industrial sustainability, making it more responsible and may provide pro-environmental solutions to the industry. This feminist concept extending it from individualistic level into mining organisations proposes as one of the alternative to combine ecology and commerce to envision sustainability.

Design of Smart Environmental Protection Supervision System in the COVID-19 Post-epidemic Era

Objectives: This research proposes a smart environmental protection monitoring system based on the Internet of Things technology, which is used to solve the monitoring data collection of the source of waste discharge of enterprises and organizations, as well as the monitoring of waste transportation and real-time monitoring at the end of waste treatment.Methods: The system covers the whole-process big data of environmental protection from waste classification and reuse, collection and transportation, online trading, production control to product traceability and government supervision. Results: Realizes unmanned supervision.Conclusions: Fills the gap in waste classification supervision in China.

Environmental pollution and health risk assessment of chemical laboratories in colleges and universities

BACKGROUND: University laboratory is an important place to carry out scientific research and related teaching activities, but the environmental pollution caused by waste discharge cannot be ignored. OBJECTIVE: The research aims to explore the environmental pollution caused by the waste of chemical laboratory, and the direct or indirect harm to human health. METHODS: The main pollutants discharged by the laboratories are counted through the analysis of the waste treatment status of university chemical laboratory. Then, the harm of the discharged pollutants to the environment is analyzed by experiments to find out the main pollution problem of the chemical laboratory - wastewater pollution. The groundwater pollution caused by laboratory wastewater discharge is analyzed, and the human health risk caused by it is evaluated. RESULTS: The results show that the discharge of chemical laboratory waste in colleges and universities will cause harm to human health. The results of health risk assessment show that benzene, trichloromethane, and dichloromethane are the main pollutants, and the use of chemical reagents is one of the important reasons for the surge of laboratory waste in colleges and universities; in the carcinogenesis of multi pollutants, compared with skin absorption, the risk of cancer caused by drinking water absorption was higher, and the corresponding risk value is 5.56e-07. CONCLUSIONS: The discharge of university chemical laboratory waste will cause harm to human health. This exploration provides reference for the study of environmental pollution and health risk assessment caused by waste discharge of university chemical laboratory.

Perencanaan Instalasi Pengolahan Limbah Cair Rumah Sakit Aliyah 3 Kota Kendari

The purpose of this study was to determine the amount of liquid waste discharge at the hospital. Data from the number of hospital patient beds is 54 beds, so the activities taking place in Aliyah Hospital 3 in Kendari city produces a maximum discharge of liquid waste of 3.78/day. The form and design of processing liquid waste which is a rectangle with anaerobic- aerobic bio filter treatment system. Liquid waste processing with anaerobic-aerobic bio filter process consists of several parts namely the oil separator tank, equalization tank, early settling tank, anaerobic bio filter tank, aerobic bio filter tank, final settling tank and equipped with a chlorinated contractor tub. As for the size of each tank, which is like an oil separator tank (0,9 m × 0,5 m × 0,7 m), equalization tank (2,6 m × 1,3 m × 1,1 m), early settling tank (1,6 m × 0,8 m × 0,9 m), anaerobic bio filter tank (2,5 m × 1,3 m × 1,4 m), aerobic bio filter tank (1,8 m × 1 m × 1 m), final settling tank (1,8 m × 0,7 m × 0,7 m) and chlorinated tank (0,6 m × 0,3 m × 0,4 m). This process system was chosen because it is in accordance with the amount of liquid waste treatment system is safe, inexpensive and easy to operate.

RISK ASSESSMENT OF HEAVY METALS IN SOILS CONTAMINATED BY SMELTING WASTE FOR THE PERSPECTIVE OF CHEMICAL FRACTION AND SPATIAL DISTRIBUTION

The heavy metals contamination in soil has attracted increasing attention. In this study, the main objective was to determine three heavy metals (Cd, Pb, and Cr) of soils contaminated by smelting waste, and to evaluate pollution risk. The Pb (15.48 mg/kg) and Cd (311.39 mg/kg) mean concentrations exceeded the national standard, while Cr (48.60 mg/kg) concentration did not exceed. The Heavy metal fractions analysis showed that three heavy metals were dominated by FeMn oxides fraction (Fe-Mn). The correlation and cluster analysis indicated that there was significant correlation between Cd and Pb (0.55< r < 0.96), while Cr was not correlation to Cd and Pb. The environmental pollution of heavy metals was assessed by the ratio of secondary phase and primary phase (RSP). The result showed that RSP values of Cd, Pb, and Cr range from 13.05–54.28, 16.11–4.97 and 1.61–52.33, which indicated soil was serious contaminated by them. These results showed that smelting waste discharge led to this smelter soil being seriously contaminated by multiple heavy metals which have a tendency to transport and accumulate into deep soil due to their high fractional transformation.
