The document summarizes the environmental impacts of the coronavirus crisis and lockdowns. It notes that air pollution decreased in many cities around the world as emissions from vehicles and industry declined. Studies found significant reductions in particulate matter levels. However, issues with improper disposal of pandemic waste including used masks and gloves emerged, and threats to ecosystems increased as environmental protection workers were unable to monitor protected areas. Overall, lockdowns provided evidence that air quality can improve with reduced activity, but long-term change requires ongoing efforts.

The Major Environmental Problems Related to Pollutionijtsrd
Pollution, also called environmental pollution, is the addition of any substance solid, liquid, or gas or any form of energy such as heat, sound, or radioactivity into the environment at a rapid rate of diffusion, dilution, decomposed, recycled, or stored in a harmless form. Pollution can take many forms the air we breathe, the water we drink, the soil we use to grow our food, the sparkling skies and even the noises we hear every day. , they can all contribute to health problems and may lead to low quality of life. Environmental pollution is one of the most serious global challenges. Wild type organisms have a slow degradation rate of hazardous substances. Currently, advanced molecular biology tools along with conventional approaches allow us to rapidly degrade or deposit hazardous materials from the atmosphere. In a developing country like India, the use of environmental standards as a decision making criterion should be properly evaluated. If the norms of developed countries apply in India, the cost would be much higher. Thus, the selected parameters should be suited to the economic condition of the country.

Rising Need for Environment Sustainable Responsibility by the Firmspaperpublications3
Abstract: The need for environmental sustainable responsibility by firms has risen on an altogether new level as the year 2011 ended with the largest ever jump in greenhouse gas (GHG) emissions. The bitter truth is that the carbon intensity of the world’s fastest growing economies is only rising despite futile efforts of UN climate talks.
It is imperative for an organization to work collectively towards reorganizing the world’s systems of energy and agricultural production by optimizing its capabilities, assets and even by flexing its political muscle to directly influence inadequate policies.
Practically this is rare as companies tend to “greenwash” their image by misrepresentation of facts to popularity & profits. On the other hand companies such as Google & IBM have been genuinely effective in playing their part in environment sustainability.

Assessment of Sulphur Dioxide Levels in Selected Sites in Athi River, Kenyaijtsrd
Industrialization, economic growth, urbanization and population growth have been responsible for air pollution in developing countries. The discharge of harmful chemicals and increased combustion of fossil fuels, affect both the physical environment and the public health. Air pollution effects are both acute and chronic on human health, ranging from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults. A study was conducted to assess the effect of sulfur dioxide on air quality at three sites in Athi River town, Kenya which included one non-industrial site. The air samples were collected by scrubbing them through appropriate trapping solutions and subsequently analyzed in the laboratory using colorimetric method. The meteorological parameters namely; temperature, relative humidity, wind speed and wind direction were also measured during the sampling exercise. The mean concentrations of sulphur dioxide at the various sampling sites during rainy season were: Shalom Hospital (602 -µg/m3); Vannilaz Restaurant (793 -µg/m3); Redeemed Gospel Church (861 -µg/m3) and Sabaki residential Estate (370 -µg/m3). The levels exceeded the guidelines recommended by WHO which has set a maximum of 500 -µg/m3, for 10 minutes exposure, however the levels at Sabaki residential Estate were low. Mean concentrations of sulphur dioxide during the dry season for Shalom Hospital, Vanillaz Restaurant, Redeemed Gospel church and Sabaki residential Estate were 863, 875,862 and 664 -µg/m3 respectively. The elevated levels of SO2 was associated with heavy vehicular traffic and the various industrial activities mainly cement manufacturing plants. Sulphur dioxide may also be emitted from diesel-powered vehicles and coal burning in the industries. The study revealed that Shalom Hospital, Vanillaz Restaurant and Redeemed Gospel Church were polluted with sulphur dioxide during the rainy season except Sabaki residential Estate but during the dry season all the sites were polluted with sulphur dioxide.

Adenoviral conjunctivitis, also known as "pink eye is a common, self-limiting condition that typically is caused by adenovirus.
Adenoviruses can cause an array of clinical diseases, including conjunctivitis, respiratory disease, hemorrhagic cystitis and gastroenteritis.
Bacteria are unicellular, procaryotic microorganisms which have diverse shape size and structures. Bacteria are found almost everywhere on Earth. Even the human body is full of bacteria, and in fact is estimated to contain more bacterial cells than human cells. Most bacteria in the body are harmless, and some are even helpful. A relatively small number of species cause disease.
A microscope is an instrument used to observe very small organisms i.e. microorganisms. The microscope provides magnification and resolution which makes the image enlarged and fine. There are different types of microscopes ranging from simple to compound microscopes.
Mitochondria are membrane-bound cell organelles (mitochondrion, singular), known as the power house of the cell that generate most of the chemical energy needed to power the cell's biochemical reactions. Mitochondria generates most of the cell's supply of adenosine triphosphate (ATP), by a process called
“oxidative phosphorylation”.
Type II Hypersensitivity-Antibody mediated cytotoxic HypersensitivityAnup Bajracharya
Type II Hypersensitivity is antibody-mediated immune reaction in which antibodies (IgG or IgM) are directed against cellular or extracellular matrix antigens with the resultant cellular destruction, functional loss, or damage to tissues.
Dark-field microscopy is used to illuminate unstained samples causing them to appear bright against a dark background. This type of microscope contains a special condenser having a central blacked-out area.

Pentose phosphate pathway is an alternative pathway to glycolysis and TCA cycle for oxidation of glucose. It is a shunt of glycolysis. It is also known as hexose monophosphate (HMP) shunt or phosphogluconate pathway. It occurs in cytoplasm of both prokaryotes and eukaryotes. While it involves oxidation of glucose, its primary role is anabolic rather than catabolic. It is an important pathway that generates precursors for nucleotide synthesis and is especially important in red blood cells (erythrocytes).
It is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA.
Convalescent plasma therapy is the treatment in which plasma that is removed from the blood of a person who has recovered from a disease is transfused into a person with the disease that fight against the causative agents and make patient safe from the diseased condition.
Acid fast staining is differential staining technique which differentiate bacteria into two group- acid fast bacteria and non acid bacteria. It used to identify acid-fast organisms such as members of the genus Mycobacterium .
When fresh liquid medium is inoculated with a given number of bacteria and incubated for sufficient period of time, it gives a characteristic growth pattern of bacteria.
If the bacterial population is measured periodically and log of number of viable bacteria is plotted in a graph against time, it gives a characteristic growth curve which is known as growth curve or growth cycle.
Growth of bacteria is affected by many factors such as nutrition concentration and other environmental factors.
Some of the important factors affecting bacterial growth are:
Nutrition concentration
Temperature
Gaseous concentration
pH
Ions and salt concentration
Available water

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

7. Nepal has been under a lockdown since
March 24 with restricted public and
transport movement across the country.
Coronavirus infections
Stay-at-home orders
schools, offices and factories limited their
activities/ closed
Road traffic dwindled to a minimum and
Airlines reduced/cancelled scheduled flights
Lockdown has brought down air pollution
levels
9. Air quality improved in the world's most polluted cities such as Bangalore, Beijing, Bangkok,
Delhi, and Nanjing, as well as the major trade centers such as New York, London, Paris,
Seoul, Sydney, and Tokyo.
Researchers measured six major pollutants, including PM2.5 and PM10, to record how air
quality improved under lockdown and travel restrictions. Researchers compared pollution
levels of February and March in 2019 with February and March 2020.
Study found that PM 2.5 concentration saw a significant decline in 17 cities in February
2020 compared to February 2019, and 14 cities witnessed declines in March 2020
compared to the same month last year.
The study conducted on 40 major cities of the world from all the six continents,
shows that air pollution levels have significantly declined in cities under lockdown.
PM2.5 and PM10 had decreased from 135.4 μg/m3 to 108.3 μg/m3 and 54.6 μg/m3 to
42.2 μg/m3 respectively in Kathmandu before and after the lockdown was enforced. Air
quality has also improved in Biratnagar and Pokhara after enforcement of the lockdown.
The WHO air quality guideline for24-hour mean PM 2. 5 should not exceed 25 μg/m³ and
that for PM10 should not exceed 50 μg/m³.

18. Air pollution worsens COVID-19 impact
• In a study scheduled to be
published in the
journal Science of The Total
Environment on 20 July,
Chinese scientists report a
clear association between
short-term exposure to air
pollution and COVID-19
infection.
• In particular, positive
associations of PM2.5,
PM10, CO, NO2 and O3 has
been established with
COVID-19 confirmed cases
in 120 cities from 23
January 23 to 29 February
in China.
Can atmospheric pollution also increase SARS-
CoV-2 lethality?
Yes, say Italian researchers in a paper to be
published in June in the journal Environmental
Pollution.
Another study conducted in Italy concludes
that the chronic exposure to atmospheric
contamination may help spread of the virus.
“We know air pollution leads to respiratory
and cardiac diseases. And looking at the
general trend of COVID-19, places with poor
air quality seems to have higher coronavirus
deaths,”
20. Different Kinds of Surfaces
• Metal- Examples: doorknobs, jewelry, silverware- 5 days
• Wood- Examples: furniture, decking 4 days
• Plastics Examples: milk containers and detergent bottles, subway and bus seats, backpacks,
elevator buttons- 2 to 3 days
• Stainless steel- Examples: refrigerators, pots and pans, sinks, some water bottles- 2 to 3 days
• Cardboard- Examples: shipping boxes - 24 hours
• Copper-Examples: pennies, teakettles, cookware-4 hours
• Aluminum- Examples: soda cans, tinfoil, water bottles- 2 to 8 hours
• Glass- Examples: drinking glasses, measuring cups, mirrors, windows- Up to 5 days
• Ceramics- Examples: dishes, pottery, mugs- 5 days
• Paper- Examples: mail, newspaper- The length of time varies. Some strains of coronavirus live
for only a few minutes on paper, while others live for up to 5 days.
• Food- Examples: takeout, produce Coronavirus doesn't seem to spread through food.
• Water- Coronavirus hasn't been found in drinking water. If it does get into the water supply,
local water treatment plant filters and disinfects the water, which should kill any germs.
• Fabrics- Examples: clothes, linens- There’s not much research about how long the virus lives
on fabric, but it’s probably not as long as on hard surfaces.
• Shoes- One study tested the shoe soles of medical staff in a Chinese hospital intensive care
unit (ICU) and found that half were positive for nucleic acids from the virus. But it’s not clear
whether these pieces of the virus cause infection.
21. Littered masks, gloves and other personal protection
gear, dumped on sidewalks, outside grocery stores and
near water bodies by the general public.
22. • In Thane, India a man was caught putting over
100,000 used face masks out to dry so that he
could resell them in the market, the Times of
India reported on March 12, 2020.
• Sanitiser bottles , masks thrown in the ocean,
water bodies is one thing, but these are
hazardous materials which are biological.
• Use of PPEs - most of which contain certain
plastic material, is setting the stage for a
global plastic waste management crisis.
• plastics that are currently being used
extensively, as 'pandemic plastics
• source of infection for sanitation workers as
well as the environment if not discarded
properly
‘Workers must have safety gear, waste be
incinerated’
23. Hospital waste
• A heap of medical waste was
found lying in the open in
different cities. Discarded face
masks, tunics, gowns, caps
and syringes were found in
the dump.
Incinerator room
24. Solution Box
• Decontaminate waste with sanitisers, put into a separate
bag and bin;
• Use reusable cloth masks that can be washed and
reused.
• For quarantine camps and home care of the suspected
patients, it is advised collection of biomedical waste in
yellow bags; bins containing these should be handed
over to authorised collectors.
• Sanitary staff should be provided safety gear such as
masks
25. Organic waste/Food waste-Garbage
• Volumes of unrecyclable waste have risen; severe cuts
in agricultural and fishery export levels have led to the
generation of large quantities of organic waste;
• Waste management temporarily halted.
• Local waste problems have emerged as many
municipalities have suspended their recycling activities
over fears of virus propagation in recycling centres.
• Due to stay-at-home policies, many consumers have
increased their consumption of take-away food
delivered with single-use packaging.
26. Ecosystems at risk
• Natural ecosystems and protected species are at risk during the
coronavirus crisis.
• In many countries, environmental protection workers at national
parks and land and marine conservation zones are required to stay
at home in lockdown, leaving these areas unmonitored.
• Their absence has resulted in a rise of illegal deforestation, fishing
and wildlife hunting.
• The stoppage of ecotourism activity has also left natural ecosystems
at risk of illegal harvesting and encroachment.
• In addition, as ecotourism is often a major economic mainstay in
many destinations, rising unemployment caused by the crisis may
lead many households to harvest resources from fragile
ecosystems unsustainably as they seek alternative means to
provide their households with food and income.
27. At last
• COVID-19 is a global pandemic and serious threat to human
health which halt the economic activities, however it is also
considered as a “Blessing in Disguise”, where pollution is
reducing and nature is reclaiming itself.
• Many of the environmental challenges caused by the
coronavirus crisis will gradually resolve on their own once
the crisis comes to an end and previous levels of economic
activity resume.
• But it is also true that the benefits of air pollution
reductions will also be erased. Overall, the crisis may thus
have no permanent environmental effects.
• This positive impact on environment may be temporary but
governments and individuals should learn from this
lockdown on how to reduce pollution on long term basis.
