A chemical accident is the unintentional release of one or more hazardous substances which could harm human health or the environment. Chemical hazards are systems where chemical accidents could occur under certain circumstances. Such events include fires, explosions, leakages or releases of toxic or hazardous materials that can cause people illness, injury, disability or death.
The preparation of national guidelines for various types of disasters, both natural and man-made
constitutes an important component of the mandate entrusted to the National Disaster Management Authority under the Disaster Management Act, 2005. In recent years, biological disasters including bio terrorism have assumed serious dimensions as they pose a greater threat to health, environment and national security. The risks and vulnerabilities of our food chain and agricultural sector to agroterrorism,
which involves the deliberate introduction of plant or animal pathogens with the intent of undermining
socio-economic stability, are increasingly being viewed as a potential economic threat. The spectre of
pandemics engulfing our subcontinent and beyond poses new challenges to the skills and capacities of the
government and society. Consequently, the formulation of the national guidelines on the entire gamut of
biological disasters has been one of our key thrust areas with a view to build our resilience to respond
effectively to such emerging threats.
The intent of these guidelines is to develop a holistic, coordinated, proactive and technology driven
strategy for management of biological disasters through a culture of prevention, mitigation and preparedness
to generate a prompt and effective response in the event of an emergency. The document contains
comprehensive guidelines for preparedness activities, biosafety and biosecurity measures, capacity
development, specialised health care and laboratory facilities, strengthening of the existing legislative/
regulatory framework, mental health support, response, rehabilitation and recovery, etc. It specifically
lays down the approach for implementation of the guidelines by the central ministries/departments, states,
districts and other stakeholders, in a time bound manner.

Bioterrorism is using living organsims as weapons of mass destruction or to cause panic in population. it has existed since ancient times and yet pose a potential future threat. this compilation is not exhaustive and contains references at the end for further reading
“Microbial forensics” has been defined as “a scientific discipline dedicated to analyzing evidence
from a bioterrorism act, biocrime, or inadvertent microorganism/toxin release for attribution
purposes” (Budowle et al., 2003). This emerging discipline is still in the early stages of
development and faces substantial scientific challenges to provide a robust suite of technologies
for identifying the source of a biological threat agent and attributing a biothreat act to a particular
person or group. The unlawful use of biological agents poses substantial dangers to individuals,
public health, the environment, the economies of nations, and global peace. It also is likely that
scientific, political, and media-based controversy will surround any investigation of the alleged
use of a biological agent, and can be expected to affect significantly the role that scientific
information or evidence can play. For these reasons, building awareness of and capacity in
microbial forensics can assist in our understanding of what may have occurred during a biothreat
event, and international collaborations that engage the broader scientific and policy-making
communities are likely to strengthen our microbial forensics capabilities. One goal would be to
create a shared technical understanding of the possibilities—and limitations—of the scientific
bases for microbial forensics analysis._ NCBI

Bioterrorism
Introduction
Bioterrorism is the intentional or threatened use of viruses, bacteria, fungi, or toxins from living organisms to produce death or disease in humans, animals or plants to accomplish political or social objectives. Agents of bioterrorism can be altered or mutated in such a way soas to increase their virulence and ability to cause disease. They can be engineered to resist current medications. They can be spread through air, food, water, fomites, or through infected hosts (including humans, animals, insects, and other reservoirs)
Chik-V & Jamaican Indigeneity: Reflections of the Accompong MaroonsAJHSSR Journal
ABSTRACT: The pursuit of this study was to establish how members of the Accompong maroon settlement in Jamaica survived the Chikungunya virus(Chik-v) with fewer reported cases as opposed to the rest of the country. The results of this research create heightened awareness on the Maroon culture in contemporary Jamaica, as well as how the virus was controlled from a disaster management cycle perspective. The disaster risk reduction strategies employed by the Maroons show that critical to their disaster epidemiology is indigenous knowledge forms, as it helps to address the prevention and spreading of vector-borne diseases, as well as situational awareness to generate information and construct mitigation strategies. This study showed that while indigenous knowledge forms do exist in this space, it is not purely indigenous, as residents had to depend on
Food is a basic necessity of all living beings on earth. Access to clean, safe and wholesome food is required to achieve complete physical and mental health. In recent days it has been feared that drinking water and food may be deliberately contaminated by terrorist organizations to disrupt social, economic and political stability of a country. With the globalization of food supply, changing food preferences, intensive food production and centralized food processing system have provided ample opportunity for intentional contamination of food at various points in food chain. Hence, it is essential to know the agents of food terrorism, various forms in which they are disseminated in to food, circumstances in which they are used, possible consequences and finally detection, prevention and response to such attacks.

Scientific Facts on Global Public Health ThreatsGreenFacts
Global public health security depends on actions to prevent and respond to threats that endanger the collective health of the global population. Those threats have an impact on economic or political stability, trade, tourism, access to goods and services and, if they occur repeatedly, on demographic stability.
Global public health security covers a wide range of complex and daunting issues, including the health consequences of human behavior, climate change, weather-related events and infectious diseases, as well as natural catastrophes and man-made disasters, all of which are discussed here.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting

Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .

6. There are number of causes why
biological weapons are potentially
more powerful agents to mass
casualties leading to civil
disruptions. To attract
widespread attention and to harm
a selected target, these outfits can
utilize
possibly any biological material,
which fulfils some of the criteria
of bio-weapons.
7. • Biological agents can be
disseminated with readily
available technology.
Common agricultural spray
devices can be adopted to
disseminate biological
pathogens of the proper
particle size to cause
infection in human
population over great
distances.
8. Biological warfare has a long history of mass
destruction through epidemic and pandemic
diseases. Limited biological warfare is reported to
have been carried out by Japan during World War-
II. Recently, mycotoxins have been reported to be
used in Afghanistan. Even before that it has also
been documented that the Red Indians in North
America were given the smallpox infected
blankets. Nevertheless, the recent Anthrax attack
in 2001 through letters caused worldwide
concerns regarding the threats of bio-terrorism.
9. Beginning in mid-September 2001, the USA
experienced unprecedented biological attacks
involving the intentional distribution of bacillus
anthracic spores through the postal system. The
full impact of this bio-terrorist activity has not
been assessed, but already the toll is large.
Hundreds of people were affected. In the 20th-
century series of cases, the mortality rate of
occupationally acquired Inhalational anthrax was
89%, but majority of these cases occurred before
the development of critical care units and in most
cases before the advent of antibiotics. Prior to
2001 attacks, at Sverdlovsk, it had been reported
that 68 of the 79 patients with Inhalational
10. However, a separate report
from a hospital physician
recorded 358
ill with 45 dead. A recent
analysis of available
Sverdlovsk data suggests that
there may have been as many
11. Even a small-scale biological attack with a
weapon grade agent on an urban center could
cause massive morbidity and mortality, rapidly
overwhelming the local medical capabilities. For
example, an aerosolized release of little as 100kg
of anthrax spores upwind of a metro city of a size
of Washington D C has been estimated to have the
potential to cause up to three millions of deaths.
12. .
The general population should be educated and
the made aware of the
threats and risks associated with it.
• Only cooked food and
boiled/chlorinated/filtered water should be
consumed
• Insects and rodents control measures must be
initiated
immediately.
• Clinical isolation of suspected and confirmed
cases is essential.
13. 2. An early accurate diagnosis is the key
to manage casualties of biological
warfare. Therefore, a network of
specialized laboratories should be
established for a confirmatory
laboratory diagnosis.
3. Existing disease surveillance system
as well as vector control measures
have be pursued more rigorously.
14. 4. Mass immunization program in the suspected
area has be more vigorously followed up.
5. Enhancing the knowledge and skills of
clinicians plays a vital role in controlling the
adverse impact of the attack. As bio-terrorism
related infections will remain rare events, creative
ongoing strategies will be required to sustain
attention to potential new cases. Action Plan for
Biological Disaster Management in India
15. Biological Disaster could arise
from a source located either
inside the country or
outside the country (warfare).
Management of such a situation
could be dealt effectively only if
there is a disaster plan well
integrated in the system and also
there is mechanism of post
