ACUTE TOXICITY OF SUGAR FACTORY EFFLUENT IN MYSTUS VITTATUS (BLOCH) : A PROBIT ANALYSIS
This paper deals with the acute toxicity of Sugar factory effluent on freshwater catfish, Mystus vittatus (Bloch),
at different concentration and duration of exposure on the mortality and ethological alterations. The LC50 for 96 hours of sugar
factory effluent for Mystus vittatus was 3.10% (v/v). The result also revealed that mortality rate depends upon concentrations
of effluent and duration of exposure. The effluent exposed test fish showed alterations in behavioural responses. The behavioural
alterations of Mystus vittatus during the present experiment was found to depend on both duration of exposure and increase in
concentration of the effluent and duration of exposure. The mortality rate was found to be directly proportional to the concentration
of effluent. Thus, the present revealed that fish, Mystus vittatus are sensitive to distillery wastewater and can be used as
biological indicators
COVID-19 Pandemic: New Challenges for Environmental Sustainability in Developing Countries
Coronavirus disease-19 (COVID-19), produced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2),
has become a global pandemic, giving rise to a serious health threat globally. The global Covid-19 pandemic is a setback for
sustainable development and compromise the world commitment to the 2030 Agenda for Sustainable Development. The
measures taken to control the spread of the virus and the slowdown of economic activities during lockdown have significant
effects on the environment. Therefore, this review discuss the indirect positive and negative impacts of Covid-19 pandemic
towards sustainable environment. This study indicates that, the pandemic situation significantly improves air quality in
different cities across the world, reduces the emission of greenhouse gases, and decreases water and noise pollution, which
may help in the restoration of the ecosystem. In addition, there are also some negative impact of Covid-19, such as increase
of medical waste, haphazard use and disposal of disinfectants, mask, and gloves; and burden of untreated wastes
continuously endangering the environment. It points to the fact that the net effect has been positive; in terms of reduction in
greenhouse emissions, oil exploration activities, and pollution. It is expected that the proper implementation of the proposed
suggestion might be helpful for the global environmental sustainability
