Air Pollution from Cement Plants: Case Study on Particulate Matter in Bihar,India

Abstract

Environmental pollution and its impact is a major challenge for this age of industrialization and urbanization. It is becoming difficult to breathe fresh air in the cities and industrial areas. Both indoor and outdoor air quality is becoming worse day by day. A study has been conducted to find out the level of particulate matter concentration inside a village near to a cement plant located in Bihar, India to know the impact of the cement plant on the ambient environment. The present study clearly indicates that during night time particulate matter concentrations of the village environment were high compared to the day times. It is also observed that there is a high concentration of particulate matter in the ambient air compared to WHO air quality guideline values in both the cases(day times and night times) due to emission from the nearby cement plant. Hence this study suggests that the cement plants and other similar industries should take proper actions to maintain the air quality standard in the ambient areas.In the last part of the article some of the pollution control techniqueshas been discussed in brief which would be helpful to the industries to improve their environmental sustainability targets.     

Species identification from dried snake venom

Illegal trade in snake parts has increased enormously. In spite of strict protection under wildlife act, a large number of snakes are being killed ruthlessly in India for venom and skin. Here, an interesting case involving confiscation of crystallized dried snake venom and subsequent DNA-based species identification is reported. The analysis using the universal primers for cytochrome b region of the mitochondrial DNA revealed that the venom was extracted from an Indian cobra (Naja naja). On the basis of this report, the forwarding authority booked a case in the court of law against the accused for illegal hunting of an endangered venomous snake and smuggling of snake venom. This approach thus has immense potential for rapid identification of snake species facing endangerment because of illegal trade. This is also the first report of DNA isolation from dried snake venom for species identification.     

Understanding food policy change in Ghana

Evidence-based policy-making has become a critical aspect of development strategy in developing countries. Yet the assumption that policymakers will automatically use available evidence may not be valid in all contexts. To influence positive policy change requires an understanding of the unique policy process and drivers of policy change in the context of a particular country and sector. Strengthening the capacity of key agricultural policy stakeholders can facilitate evidence-informed policy-making. This article documents an approach to strengthening the capacity of parliamentarians in Ghana. It attempts to measure to what extent such investments could lead to informed policy-making to promote poverty reduction. Lessons are drawn from a group of Ghanaian parliamentarians following an exposure and learning visit to India.     

Can computed tomography replace or supplement autopsy?

Postmortem computed tomography (PMCT) has been integrated into the practice of many forensic pathologists. To evaluate the utility of PMCT in supplementing and/or supplanting medicolegal autopsy, we conducted a prospective double-blind comparison of abnormal findings reported by the autopsy pathologist with those reported by a radiologist reviewing the PMCT. We reviewed 890 cases: 167 with blunt force injury (BFI), 63 with pediatric trauma (under 5 years), 203 firearm injuries, and 457 drug poisoning deaths. Autopsy and radiology reports were coded using the Abbreviated Injury Scale and abnormal findings and cause of death (COD) were compared for congruence in consensus conferences with novel pathologists and radiologists. Overall sensitivity for recognizing abnormal findings was 71% for PMCT and 74.6% for autopsy. Sensitivities for PMCT/autopsy were 74%/73.1% for BFI, 61.5%/71.4% for pediatric trauma, 84.9%/83.7% for firearm injuries, and 56.5%/66.4% for drug poisoning deaths. COD assigned by reviewing PMCT/autopsy was correct in 88%/95.8% of BFI cases, 99%/99.5% of firearm fatalities, 82.5%/98.5% of pediatric trauma deaths, and 84%/100% of drug poisoning deaths of individuals younger than 50. Both autopsy and PMCT were imperfect in recognizing injuries. However, both methods identified the most important findings and are sufficient to establish COD in cases of BFI, pediatric trauma, firearm injuries and drug poisoning in individuals younger than 50. Ideally, all forensic pathologists would have access to a CT scanner and a consulting radiologist. This would allow a flexible approach that meets the diagnostic needs of each case and best serves decedents' families and other stakeholders.     

From women for women: The role of social media in online nonprofit activities during Wuhan lockdown

The article examines the role of social media in mitigating information asymmetry and coordination problems during COVID-19 epidemic crisis. We use “Sisters-Fight-Epidemic” online volunteering project during the outbreak of COVID-19 in Wuhan, China, as a case to demonstrate how social media plays a role as a mechanism in linking multiple stakeholders and shaping their actions during the epidemic response. We show that social media facilitates the self-organizing processes of volunteers and develops the emergency information networks, therefore enabling a relatively efficient relief responses to the needs of epidemic victims particularly female medical workers. This article also identifies spontaneous online volunteering project as a new form of nonprofit organization and as a new emergent response group that can leverage the strengths of social media in disaster responses to enable effective coordination, initiate advocacy, and improve transparency of relief efforts.     

Unemployment Insurance benefit reduction and food hardship

We leverage the sharp drop in unemployment insurance (UI) benefits following the expiration of the Federal Pandemic Unemployment Compensation program to estimate the consumption smoothing effect of UI. The $600/week decline in supplemental UI benefits is estimated to reduce total food spending by 9.7% and the odds of having food sufficiency by 6.0%. The estimate for food spending translates to a marginal propensity to spend on food out of UI benefits of 0.06, or a 1.2% reduction in food spending for every 10 percentage point decline in UI replacement rate (calculated as the ratio of UI benefits to pre-unemployment wages). We find that the consumption effect of UI is countercyclical, greater when economic conditions are weak. The UI effect is also heterogeneous over respondents differentiated by race and ethnicity, income, homeownership, presence of children, state unemployment rates, and state UI generosity. The estimated effect of UI on self-assessed food sufficiency and confidence about future food sufficiency is largely consistent with the food spending results.     

Distribution of malathion in body tissues and fluids.

Six cases of suspected poisoning were studied. The various body tissues and fluids of all the cases were analysed and malathion was found positive. The quantitative analysis was performed using high performance liquid chromatography. The distribution of malathion was studied in lungs, liver, kidneys, spleen, brain, heart, blood, muscles, urine and gastric contents.
