Dear Readers, In a way the spread of COVID-19 has forced the globe to halt all outdoor manmade activities for the longest period in the memories of the present population of this planet. This lockdown will probably be be marked in history forever. Nevertheless, this shutdown is a rejuvenation of the Earth, environment and human health systems. Despite the sudden changes to the daily behaviour of humans, our surrounding ecological systems are enjoying holistic and positive changes. This is a k

COVID-19是一种由新发现的冠状病毒引起的传染病，通过呼吸道飞沫和接触在人与人之间传播。Covid-19已知会影响呼吸系统，导致从普通感冒到更严重的疾病的感染，其常见症状包括发烧、疲倦、干咳、呼吸短促或呼吸困难，而一些感染者则没有任何症状目前，没有专门的疫苗或治疗方法，

森林砍伐、生物多样性丧失和气候变化是这个星球面临的一些较为确定和有害的社会环境问题。近年来，与这些有害问题作斗争的现有技术急剧增加。然而，与此同时，我们继续看到不可持续的环境退化。许多人发现了人类的环境价值与对自然系统关注的减少之间的关系在这里，我认为解释超出人类的能力

Introduction Air quality standards The issue of air quality in the National Capital Region (NCR) Delhi is a matter of public concern. Poor air quality has various harmful effects on the environment and human health causing smog, acid rain, reduced visibility and increasing premature deaths, asthma attacks and chronic respiratory illness.1,2,3 In general, poor air quality of Delhi is due to high concentrations of the PM2.5 and PM10 which have been reported violating the limits of N

Introduction Over the years, rivers are progressively subjected to environmental stress caused by human intervention.1 Water quality of a river is being carved up by several interrelated factors, which are subjected local and temporal variations in addition to discharge.2 As a result of increased anthropogenic pressure including pollution, large-scale damming, sand mining etc., the natural self purification capacity of rivers becomes restricted to a minimal level.3 Excessive loading of nutrie

Introduction The construction industries play an important role in country development. Generally, construction workers perform their activities in open sky, various weather conditions as well as unsafe workplaces. That is why the construction workers around the world face various occupational injuries.1 Tahir et al.,2 depicted that, construction sectors as industry having the capability of making different risks and perils to agents with the capacity of bringing about injur

Introduction Floodplains are one of the most important and fertile ecosystems of the earth. These are depositional smooth features created by the river along its course (Wooldridge and Morgan 1959; Wolman and Leopold 1970; Gregory and Willing 1973) characterized by periodical overflow of river and wet and dry spells. Regular floods are an important characteristic of the floodplains which deposit a layer of fertile soil. Several great ancient civilizations of the world developed in the floodpl

Introduction Plastic materials are used almost everywhere from ordinary polythene bag to biomedical fields. Although plastic is a major environmental pollutant1 in the environment. Petroleum derived plastics accumulation2 is a major cause of pollution for the environment and its adverse effect destroying the balance in the eco system. So it is a novel approach to produce plastic using microbes and bioplastic3 is the answer of this problem. These biopolymers can break down into biomass, water

Introduction In Nigeria, the poor structure and framework for the utilization of gas deposits associated with crude oil drilling has led to the continuous flaring of reusable gases (Ajugwo, 2013; Ifenkwe et al., 2018) and the consequent loss of foreign exchange earnings to the country. Following the presence of numerous gas flaring stacks at Imiringi community, some of the most affected environmental aspects include the surrounding vegetation, agricultural farm lands and the overall health o

Introduction To meet the increasing demand of the population, massive exploitation of environmental resources has taken place in the recent times and is ongoing every day. Threats to environment from the progressive deterioration of the biosphere have emerged as one of the primary issues of the recent times. Various human induced activities have direct and indirect impacts on the environment. Stone crushing and quarrying is one of such activity. Though socioeconomically stone crushing and qua

Introduction Sanitation is directly related to public health and a variety of health related facilities are provided by the government to the society but basically public health is associated with sanitation. In general, sanitation is the responsibility of local bodies like Nagar Nigam, Nagar Palika Parishad and Nagar Panchayat at urban level and Gram Panchayat and Jila Panchayat at rural level. Though these bodies are responsible for multiple services like education, registration of birth/

Introduction The algal blooms produced by cyanobacteria have shading effect on the lower layers, resulting in more respiratory activities below the surface and suffocation of fauna.1,2 Some freshwater algae e.g. Microcystics, Chlorella, Trichodesmus and Phormidium are harmful as they produce biomass which generate bad smell, causing de-oxidation and damage to aquatic life.3 The excessive growth of some species microalgae especially those of Microcysticsa nd Lyngbya lead to anoxia (lack of oxy

Introduction Untreated and semi-treated effluents from tanneries and other industries are often discharging in to the environment, particularly in developing countries. Farmers’ are ignorance about the hidden toxicity of such heavily polluted discharges and their subsequent negative impacts has led to its continued use in cultivation of cereals, vegetables and others economically important plants.1 The discharge from various sub-processes in tanneries like bathing, pickling, tanning

Introduction Human induced perturbances and hydrological conditions such as amount of precipitation, water loss due to high heat inducers can modify the physical and chemical characteristics such as soil salinity, nutrient availability, pH, sediment properties and degree of substrate anoxia. These changes in physico - chemical environment have direct impact on the biotic component of the water body. The ecological parameter of such water bodies may provide clues for understanding the key rela

Introduction Indian power generation is in majority dependent on coal-based thermal power station. The coal combustion products produced every year is around 112MT (million tons) in India and it exceeds 225 MT by 2017[Singh, 2012]. Impact assessment of fly ash on environmental are very complex and detailed research is important and analysis of the side-effects on plants and soil is need of the hour. Sustainable agriculture needs careful use of any organic amendments to improve the fertility

Introduction Environmental pollution and energy shortages have become the major sectors restricting progress and economical development of the country.1–4 Some researchers have explored nowadays various solar applications for simultaneous solar fuel cells and photocatalysis using iron-graphene oxide-titanium phosphate,5 photocatalysis with cadmium sulphide,6 transition metals doped CuO for heterojunction solar cells,7 carbon nanotubes on cobalt-iron-silica electrocatalysis.8 Active
