Noise pollution occurs when unwanted or excessive sound disrupts normal activities. It can come from sources like transportation, construction sites, social events, and household appliances. Noise pollution negatively impacts humans, animals, and the environment. It can cause health issues like hearing loss, high blood pressure, fatigue, and poor mental health in humans. Animals exposed to noise pollution experience problems with communication, metabolism, and behavior. Prevention efforts include proper maintenance of vehicles and machines, turning off engines when not in use, and wearing earplugs in loud areas.
This ppt contains the information about environmental noise pollution. ppt contains information related to noise pollution, sources of noise pollution, their types, different noise levels, effects of noise pollution on animals as well as on humans and also contains the tips for prevention of noise pollution.

A sound, especially one that is loud or unpleasant or that causes disturbance.
Noise pollution is the disturbing noise with harmful impact on the activity of human or animal life. The source of outdoor noise worldwide is mainly caused by machines, transportation systems, motor
vehicles engines and trains. Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
Sound becomes unwanted when it either interferes with normal activities such as sleep, conversation, or disrupts or diminishes one's quality of life.
Noise pollution affects both health and behavior. Unwanted sound (noise) can damage psychological health. Noise pollution can cause hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.
Chronic exposure to noise may cause noise-induced hearing loss.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

2. What is Noise ?
Sound that which is unwanted and distrupts
one’s quality of life, is known as NOISE.
Normal sound becomes undesirable when it
disturbs our normal activities such as
working , sleeping and during conversation.
World Health Organization stated that “Noise
must be recognized as a major threat to
human well-being”.
3. Types of Noise:-
Atmospheric
noise.
Extraterrestrial
noise.
Industrial noise.
Man made noise.
Thermal noise.
Shot noise.
Transit time noise.
Miscellaneous
noise.
External Noise:- Internal Noise:-
4. Sources of Noise Pollution:-
THESE ARE THE MAIN SOURCES OF NOISE
POLLUTION :-
Household sources.
Social Events.
Commercial & Industrial Activities.
Transportation.
5. Household Sources:-
Gadgets like food mixer, grinder, vacuum
cleaner, washing machine and dryer, cooler, air
conditioners, can be very noisy and injurious to
health.
Others include loud speakers of sound systems
and TVs, ipods and ear phones.
Another example may be your neighbour's dog
barking all night everyday at every shadow it
sees, disturbing everyone else in the apartment.
7. Social Events:-
Places of worship, discos and gigs, parties and
other social events also create a lot of noise for the
people living in that area.
In many market areas, people sell with loud
speakers, others shout out offers and try to get
customers to buy their goods.
It is important to note that whey these events are not
often, they can be called “Nuisance” rather than
noise pollution.
9. Commercial & Industrial
Activities:-
Printing presses, manufacturing
industries, construction sites contribute the noise
pollutions in large cities.
In many industries it is a requirement that people
always wear earplugs to minimize their explosure to
heavy noise.
People who work with noisy equipments are
required to wear noise-proof gadgets.
11. Transportation:-
Aeroplanes flying over houses close to busy
airports.
Over ground and Under ground trains ,vehicles on
roads, these are constantly making a lot of noise.
15. ON HUMANS:-
Noise pollution is the reason for cause of nervous
disorder, headache, high blood pressure and short
memory.
Depression and fatigue, which considerably reduces
the efficiency of a person.
Frustration and difficulty in
concentration, disturbance of rest, physical and
mental fatigue.
Chronic exposure to noise may cause noise-induced
hearing loss.
17. ON ANIMALS:-
Noise pollution damages the nervous system of
animal.
Increase of death by altering the prey/predator
detection and avoidance.
Animal looses the control of it’s mind.
Creates problems in their use of sounds in
reproduction and navigation.
They becomes dangerous and attacking.
18. ON ANIMALS:-
Noise pollution from ship engines and sonar
systems make it difficult for marine mammals like
whales & dolphins, & prevent it from
communicating, finding food, and avoiding hazards.
Excessive noise has the ability to raise an animal’s
heartbeat speed and even harms an animal’s
metabolism.
20. ON ENVIORNMENT:-
Noise also has detrimental effects on the growth of
some plants.
Birds as well rely on hearing to help find them to
prey, hence they are seriously disadvantaged by
noise.
Because the noise is breaking the earths barrior and
that could lead to destruction of the world in about
2-3 yrs.
Noise pollution causes poor quality of crops in
pleasant atmosphere.
21. Prevention of Noise
Pollution:-
Do not use car horns unnecessarily. Areas like
hospitals and campuses are silence zones and
horning is prohibited there.
22. Prevention of Noise
Pollution:-
Motors, machines and vehicles also produce loud
noises when not maintained properly. Proper
maintenance should be carried out for better
performance.
23. Prevention of Noise
Pollution:-
Turn off the engine of your car or motorbike when
you are not using it. It stops the annoying hum, and
reduces air pollution also!
24. Prevention of Noise
Pollution:-
If you are working in an area where there are loud
noises, you must wear earplugs to prevent loss of
hearing.
