Earth is consisting of land, air and water. Air contains oxygen, nitrogen, carbon dioxide, water vapor, other gases are present above the permissible limit, and it creates effects on human health. It is one of the most important public health issues due to development of urbanization, industrialization and globalization in large cities. Air pollution levels in developed countries have been increased in recent years. In developing countries air pollution levels are still high. In recent years, the health studies have become visible showing harmful health effects in lungs and respirable system. Air pollution is responsible for 7million deaths annually. It affects the health of humans and other living beings in our world. The government has developed the guidelines for air quality and rule to restrict emissions in effort to control air pollution. These updated AQGs provide exact guidelines for PM 10 and pm 2.5. The primary objective of this paper is to study the ambient air quality and its impact on lungs. Particulate matters are the particles suspended in air/atmosphere. Mainly PM10and PM 2.5Ultra fine particles (<1µm) are mainly responsible for causing interruption for human health.PM10 and PM2.5 are characterized by their presence only within the upper respiratory tract. Some PM 2.5 and Ultra fine particles are characterized by their presence deeper regions of alveoli. Ultrafine particles (PM0.1), which are present in the air in large numbers, pose a health risk. They generally enter the body through the lungs but translocation to essential organs. Compared to fine particles (PM2.5) ,they cause more pulmonary inflammation and are retained longer in the lung. Their toxicity is increased with smaller size, larger surface area, adsorbed surface material, and the physical characteristics of the particles. Exposure to PM0.1 induces cough and worsens asthma. Metal fume fever is a systemic disease of lung inflammation most likely caused by PM0.1. The disease is manifested by systemic symptoms hours after severe exposure to PM0.1 could cause systemic inflammation, endothelial dysfunction, and coagulation changes that predispose individuals to cardiovascular disease and hypertension.

Trees in the forest are an unprecedented cluster of organisms in ecological, monetary and social importance. With a wide distribution, mostly random spread over and a large population in terms of size, the majority of tree species show considerable variation in genetics both within and between populations. The genus Phytophthora, is a most destructive plant pathogen and attacks a wide range of tree hosts, including inexpensively its significant species. Many species of Phytophthora are known to be persistent and brought in through nurseries and commercial agriculture. Diseases from various eucalyptus tree species were first reported in India and the symptoms, incidence and leaf damage have been described. As an observation of a larger project to use genomic data for tree disease diagnosis, pathogen detection and surveillance, in this study the significant analysis of various DNA sequences of P.meadii 2 on eucalyptus tree species in Indian Forests. The identified outcomes observed that the high frequency of nucleotides and their combinations found in the organisms in trees threatening their lives may be observed and has to be condensed

Unicellular microalgal culture represents a new opportunity for producing significant biofuel quantities in the future along with other specialty products, due to several major advantages microalgae species present when compared to conventional crops, including much faster growth rates, cultivation in a variety of environments and photobioreactor systems, and almost 100% recycling of nutrients. In the current research, the scaling-up of the cultivation of Chlorella vulgaris microalgae to a 4 m3 pilot-plant photobioreactor is examined, compared to the performance of a 25 L automated laboratory bioreactor. Beyond the size and configuration, the main differences of the two bioreactors are the mode of operation, the illumination nature and depth, the temperature, and pH. Specifically, temperature and illumination are naturally varying from day to day and season to season into the pilot-plant photobioreactor that is set inside a greenhouse. The specific growth factor appears to be higher for microalgal cultivation in the laboratory bioreactor. It is also found that the growth kinetics is severely slowed down during the winter months. This is primarily due to the low temperatures and the poor illumination observed during winter.

This research focuses on hydrothermal gasification (HTG) and hydrothermal liquefaction (HTL) studies to produce bio-hydrogen from domestic mixed waste. HTG and HTL studies were studied at temperatures of 300–450°C and 300–400°C, correspondingly, with a catalyst level of 6 wt %. The sol-gel technique was used to make the Bentonite/Nb-TiO2 catalyst. For a solvent-waste proportion of 14 millilitre/gram, an C2H5OH - water proportions of 2:2, and a period of one-hour, maximum H2 output from HTL was 30 wt % (catalyst loads: 4 wt %) and HTG was 40 wt % (catalyst loads: 5 wt %). As C2H5OH acts as half-solvent and ideal solvent to bio-mass capacity it shot up H2 result in the HTG procedure by methanation, gas water shift and improving responses in the organization. The second output of the HTL procedure was bio-oil, which yielded 35 wt % with O/C as well as H/C standards of 1.2 and 1.0, respectively, and an HHV of 42 Mega Joule/kilogram. In the HTL system, mechanistic procedures such depolymerization, hydration, reduction, and hydrolysis generated in a larger proportion of gaseous product. Thermal and the solvent-to-waste proportion is the ideal factors in the H2 synthesis procedure, according to experimental analysis. Energy nexuses from domestic mixed trash are taken over in this research.
