Microplastics are Everywhere  

DOI: 10.5281/zenodo.7133067 

Zorawar Singh

The widespread use and misuse of plastics has resulted in serious environmental degradation issues which need to be addressed with immediate effect. Plastic is one of the most common types of marine debris found in our oceans and lakes. Plastic debris can come in any size and shape. But plastic particles less than five millimeters long are called microplastics. These tiny pieces could take decades or more to degrade fully. Thus, it is important to manage plastic use and disposal.

Significance Determination of Best Practices in the Perth-Darwin National Highway (Swan Valley Section), Western Australia  

DOI: 10.5281/zenodo.7133094 

Priya Khangotra

Environmental Impact Assessment (EIA) is a process to determine, allocate, and intercommunicate the most significant impacts of a developed project related to the environment hereby, environmental significance as a concept is at the heart of discretional decision-making in the process of EIA. This review paper aims to analyze how significance is addressed to the Perth- Darwin National Highway project as well as to mitigate the environmental impacts by applying best practice criteria of significance determination. Further, various surveys were conducted to investigate the potential impacts on species in flora and fauna environmental factors.

Implications of Climatic Change on Physico-chemical Parameters of Freshwater and Fisheries: A Review  

DOI: 10.5281/zenodo.7133104 

Mohita Sardana, Amit Priyadarshi and Dina Nath Pandit

Climate change refers to long-term local, regional and global alternations in average temperature and weather patterns. It has been a global concern in recent decades and is related to human activity. Fish can be stenothermal or eurythermal as well as warm-water or cold water depending on their tolerance limits of temperature. The decline of global fish production because of climate change in many parts of the world is widely documented as fishing down the food web or overfishing may lead to further decline of fisheries production and food insecurity. Changes in physicochemical parameters of water are one of the most important consequences of climate change that will have a significant impact on the fisheries. Water temperature is directly proportional to most of the physicochemical parameters such as turbidity, salinity, conductivity, FCO2, total hardness, TDS, nitrate, and ammonia. pH and DO have an inverse relationship, whereas BOD showed a direct relationship up to 500C but total alkalinity and chloride provide no definite relationships. In this study, a relationship between these physicochemical parameters with raising or lowering temperature as well as the perspective consequences on fisheries is reviewed.

Application and Fastness Analysis of Natural Dyes on Cotton Knitted Fabric  

DOI: 10.5281/zenodo.7133115 

Neaz Morshed, Zakaria Ahmed, Ashraful Alam, Pulak Talukder, Taslima Rahman

The study was projected to application and fastness analysis of natural dyes on cotton knitted fabric with references to measure color fastness to four criteria; like color fastness to wash, color fastness to perspiration, color fastness to light and color fastness to rubbing. Test was carried out for 30min at 60oC and grading was done for color staining and color change by the respective grey scale. But change in color grading was very poor; the lowest grade was found for turmeric and combination of tea and henna was 1. The rubbing fastness of the sample cloth and degree of staining is accessed both for wet and dry rub by grey scale. Color fastness to light was carried out in the Xenon Arc. Dry rub grading was 5 and Wet rub grading was 4. Rubbing fastness properties of these natural dyes were comparatively poor and the results of the grading for light fastness were very poor.

Reproductive Behaviour in Agapornis roseicollis  

DOI: 10.5281/zenodo.7133130 

Jasjit Kaur Randhawa and Lakhvinder Singh

Agapornis roseicollis commonly known worldwide as rosy-faced or peach-faced African lovebird has got much recognition as a pet in recent years. When the African continent was explored, the western world also made acquaintance with lovebirds. The first variety to be scientifically described in 1788 was Agapornis pullarius and the last was a subspecies of Agapornis roseicollis, Agapornis roseicollis catumbella, which was scientifically registered as late as 1955. In the ongoing research, a study was conducted on a colony of lovebirds to understand the reproductive behaviour during the breeding season under captivity. All the birds under study were of an average age of 12-14 months. All the essential external factors like photoperiod, food availability, temperature, humidity etc. which could affect the reproductive behaviour were maintained. The birds were closely monitored, and remarkable behavioural changes were observed with respect to feeding, nesting, territorial behaviour and mating rituals. This paper is important as good knowledge of reproductive behaviour may be of paramount significance to understanding the factors affecting reproductive success and developing a conservation management plan if the species gets threatened or endangered in the near future.

Environmental Radon, Thoron and their Decay Products may cause Lung Cancer: Need for Effective Measurements  

DOI: 10.5281/zenodo.7133138 

Parminder Singh

Study of radon (222Rn), thoron (220Rn) and their daughter products is an important aspect as they are the main contributors to the total radiation dose inhaled by human beings from natural radioactive sources. The contribution of radiation dose from daughter elements of 222Rn and 220Rn are more harmful and they cannot be neglected. The alpha-emitting, short-lived decay products are present everywhere in the environment in attached or unattached fractions of air particles. During inhalation, these daughter products stay in the lungs, which may lead to lung cancer.
