Managing menstruation in a hygienic way is a challenge in most of the low and middle-income countries (LMIC) including Nepal, where normal and natural physiological process of menstruation is considered as girls’ problem which is viewed as sinful, unholy and matter of shame. This paper explores the current practice and existing difficulties that adolescents girls encounter hygienic management of menstruation (MHM) especially during school days. The study was conducted on five purposively selected community schools of Chitwan district. The study adopted Participatory Action Research (PAR) as an approach, that is encapsulated with mixed method research design. For qualitative information observation, focus group discussions (FGD) and field notes were used, whereas for quantitative data self-administrative questionnaires were used. Quantitative information was collected from 205 girls students who were present at schools on the day of data collection. The finding shows that majority of the girls (93.7%) who encounter hygienic management of menstruation were of 10-14 years old age, whereas nearly one third of them were (29%) from grade eight. Similarly, among the total 205 girls, only 79 girls have already started their menstruation; among those who have started menstruation majority (78%) had heard about menstruation form their mothers. Likewise, 35% girls used homemade cotton pads and 40.5% of them changed pad three times a day. During FGD, adolescents girls shared that lack of water and soap in toilets, stress and lack of concentration during menstruation are the major difficulties which they encounter during days of menstruation. They suggested the concerned authorities to manage pad bank, make soap and water available, and develop skills for proper disposing of used sanitary pads for MHM at schools.

Dioctyl phthalate (DOP) commonly used as plasticizer enters into aquatic environment from the industries manufacturing plastic products, PVC resins, cosmetics and many other commercial products. Therefore, this study was designed to evaluate the acute toxicity effects of Dioctyl phthalate on fresh water fish Clarias batrachus. The 96 hour LC50 of Dioctyl phthalate in Clarias batrachus was estimated as 14.5ml/L. Histopathological changes in liver of Clarias batrachus were determined by exposing them to a fraction of LC50(1/5th) dose with every change of water for 30 days.The liver of Clarias batrachus was excised at every interval of 30 days and histological changes of liver were studied under light microscopy. Liver tissues showed abnormalities. Centrilobular vacuolation, necrosis, eccentric nuclei and enlarged nuclei, Centrilobular degeneration of hepatocytes were observed in liver tissue of fish.

A complete understanding of the occurrence of microplastics and the methods to eliminate their sources is an urgent necessity to minimize the pollution caused by microplastics. The use of plastics in any form releases microplastics to the environment. Existing policy instruments are insufficient to address microplastics pollution and regulatory measures have focussed only on the microbeads and single-use plastics. Fees on the use of plastic products may possibly reduce their usage, but effective management of plastic products at their end-of-life is lacking. Therefore, in this study, the microplastic–failure mode and effect analysis (MP–FMEA) methodology, which is a semi-qualitative approach capable of identifying the causes and proposing solutions for the issue of microplastics pollution, has been proposed. The innovative feature of MP–FMEA is that it has a pre-defined failure mode, that is, the release of microplastics to air, water and soil (depending on the process) or the occurrence of microplastics in the final product. Moreover, a theoretical recycling plant case study was used to demonstrate the advantages and disadvantages of this method. The results revealed that MP–FMEA is an easy and heuristic technique to understand the failure-effect-causes and solutions for reduction of microplastics and can be applied by researchers working in different domains apart from those relating to microplastics. Future studies can include the evaluation of the use of MP–FMEA methodology along with quantitative methods for effective reduction in the release of microplastics.

Menstrual hygiene management and health is increasingly gaining policy importance in a bid to promote dignity, gender equality and reproductive health. Effective and adequate menstrual hygiene management requires women and girls to have access to their menstrual health materials and products of choice, but also extends into having private, clean and safe spaces for using these materials. The paper provides empirical evidence of the inequality in menstrual hygiene management in Kinshasa (DRC), Ethiopia, Ghana, Kenya, Rajasthan (India), Indonesia, Nigeria and Uganda using concentration indices and decomposition methods. There is consistent evidence of wealth-related inequality in the conditions of menstrual hygiene management spaces as well as access to sanitary pads across all countries. Wealth, education, the rural-urban divide and infrastructural limitations of the household are major contributors to these inequalities. While wealth is identified as one of the key drivers of unequal access to menstrual hygiene management, other socio-economic, environmental and household factors require urgent policy attention. This specifically includes the lack of safe MHM spaces which threaten the health and dignity of women and girls.

Menstrual practices of adolescent girls in rural parts of India are greatly influenced by taboos and socio-cultural beliefs. In this study, the menstrual hygiene practices and beliefs of 122 adolescent girls between the ages of 13 and 19 years from rural Maharashtra were evaluated by personal interview and questionnaires. None of the girls had the right scientific knowledge about menstruation and were isolated during menstruation. They used cloth or home-made sanitary pads and were at risk of infections. There is a dire need for knowledge dissemination among school children and their families, increased awareness of menstrual hygiene and access to the requisite sanitary products in rural areas.
