Environmental Toxicology

Pollution refers to the presence and undesirable changes occurring in the physical, chemical, and biological composition of the natural environment consisting of air, water, and soil that has harmful effects. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is the introduction of contaminants into the environment and that is called environmental pollution.

Health is entirely depending upon environment and due to this any harmful particle in environment leaves its bad impact on health. Regarding this reason some safety rules should be followed whether in workplace or other. Our concern is to aware people about the safety rules which, if followed will built a better environment.

Human impact on the environment includes changes to biophysical environments and natural resources.  It gets affected by humans, including global warming, environmental degradation, mass extinction and ecological collapse. Adjusting the environment to fit the needs of society is causing severe effects, which become worse as the problem of human overpopulation continues.

Risk assessment and management generally deals with identification of hazards, analyzing and evaluating the risks associated and minimize those risk. The General Approaches to Environmental Risk assessment and management involves techniques help in creating awareness about the different potential hazards, identifying the people who pose the major risk because of the biohazards; formulate the control measures and prioritizing the hazards and control measures.

Environmental agents are the things which are highly used in our society as well as which are hazardous for environment. These agents are having in numerous reproductive and developmental health effects. Patient exposure to toxic environmental contaminants at any point of time may lead to harmful health outcome.

All populations will be influenced by climate change, but a few are more vulnerable than others. Individuals living in small island developing states and other coastal districts, megacities, and mountainous and polar regions are especially vulnerable. Over the final 50 years, human activities – especially the burning of fossil fuels have released adequate amounts of carbon dioxide and other greenhouse gasses to trap additional heat in the lower atmosphere and influence the worldwide climate change. In spite of the fact that global warming may bring a few localized benefits, such as fewer winter deaths in mild climates and increased food production in certain regions, the overall health impacts of a changing climate are likely to be overwhelmingly negative. Climate change impacts social and common determinants of wellbeing – clean air, safe drinking water, satisfactory nourishment and secure shield. Locale with frail prosperity system – for the most part in developing nations – will be the least able to oversee without help to get prepared and respond.

Healthcare management, also called as healthcare administration, is the administration, management or supervision of healthcare systems, hospitals, entire hospital networks or other medical facilities. Healthcare Management is the profession that provides leadership and direction to organizations that deliver personal health services, and to divisions, departments, units, or services within those organizations. Duties of these professionals include ensuring that individual departments run smoothly, qualified employees are hired, information is communicated efficiently throughout the organization, specific outcomes are reached, and resources are used efficiently, among many other responsibilities.

The study of dangerous effects on human beings by chemicals used in the workplace, the products produced by companies, and the wastes created in manufacturing is known as industrial toxicology. Particular industries, such as the pharmaceutical and pesticide industries commonly should conduct many studies and experiments to demonstrate the safety of the chemicals that they develop. The product development toxicology biochemical and molecular toxicology, chemical toxicology, heavy metals and acute zinc and iron toxicity are few industrial effects.

Global warming is referring to a drastic change in climate due to increase in the temperature of the Earth's aerosphere. The increased quantities of CO2 and other greenhouse gases spread by the burning of fossil fuels, agriculture, land clearing and other human activities are believed to be the primary sources of the global warming. Global warming may cause rise in sea levels due to the melting of the polar ice caps, as well as a growth in happening and severity of storms and other severe weather events.

The most important risk in agriculture derives from exposure to pesticides. Evaluation of the extensive toxicological studies required for all pesticides. From the past 50 years, agriculture has deeply changed with a massive utilization of pesticides and fertilizers to enhance crop protection and production, food quality and food preservation. Pesticides are unique chemicals as they are intrinsically toxic for several biological targets, are deliberately spread into the environment, and their toxicity has a limited species selectivity. The post-marketing risk assessment takes place during the use of pesticides and aims at assessing the risk for exposed operators.

Green chemistry is the design of chemical products and those reduces or eliminate the use or generation of hazardous substances. Green chemistry applies across the life cycle of a chemical product, including its design, manufacture, use, and ultimate disposal. Green

Chemistry focuses on the environmental impact of chemistry, including technological approaches to preventing pollution and reducing the consumption of non-renewable resources.

Regulatory toxicology comprises the study of a toxicity profile that is compared with other known toxicants. Regulatory toxicology works as the major center for laws that limit exposures for people and the environment. The regulatory toxicology is to control production, use, and deposition of dangerous materials to prevent adverse effects on human health and the environment. This requires enough information on the hazardous properties of a chemical compound, their relevance to man and of human and environmental exposure, which is a prerequisite for appropriate risk assessment and the decision whether regulatory consequences are warranted.

Public Health Nursing or community health nursing is a Nursing specialty aimed to improve public health. It is the combination of Nursing and Public health practice used to protect and promote the health of population. It combines all the principles of professional, clinical nursing with public health and community practice. Public health nurses work within communities and focus on different areas to improve the overall health of the people within that community by educating individuals about the healthy lifestyles like educating benefits of various fruits and vegetables, educating about the healthy eating plate, educating healthy eating pyramid.

General wellbeing is "the science and craft of counteracting disease, dragging out life and advancing human wellbeing through sorted out activities and educated decisions of society, associations, open and private, groups and people. Public Health is interdisciplinary. For instance, the study of disease transmission, biostatistics and wellbeing administrations are for the most part significant. Natural Health, group happiness, Behavioural health, security financial aspects, open arrangement, psychological Health and word related security are other essential subfields. PHC incorporates all zones that undertake a part in health, for example, access to Health administrations, condition and lifestyle. Thus, essential medicinal services and general health measures, taken together, might be considered as the foundations of all-inclusive wellbeing frameworks
