4^th World Congress on Environmental Toxicology and Health Safety April 16-17, 2021 Barcelona, Spain

Climate change, additionally called an Earth-wide temperature boost, alludes to the ascent in normal surface temperatures on Earth. Environmental change is an adjustment in the factual circulation of climate designs when that change goes on for an extended time allotment (i.e., decades to a large number of years). Natural change may allude to an adjustment in normal climate conditions, or in the time variety of atmosphere inside the setting of longer-term ordinary conditions. Environmental change is brought about by elements, for instance, biotic methodology, varieties in sunlight based radiation gotten by Earth, plate tectonics, and volcanic emanations.

Environment Health and Safety is an order and claim to fame that reviews and actualizes pragmatic parts of natural insurance and wellbeing at work. From a natural perspective, it includes making a logical way to deal with yielding with ecological guidelines, such as overseeing waste or air emanations right to helping locales diminish the organization's carbon impression. From a wellbeing and security perspective, it includes trying endeavors and systems for recognizing working environment perils and decreasing mishaps and presentation to unsafe circumstances and substances.

The collection, transport, processing, managing and monitoring of waste materials is known as waste management .Waste management could be a distinct observe from resource recovery that focuses on the optimum utilization of the natural resources with social responsibility. It aims at unearthing the recent innovations and developments in this field with a view to check global warming. All the activities and actions needed to manage waste from is getting down to its final disposal.

Health resources include all the staff that is directly or indirectly involved in any health issue concern the field of health human resources deals with problems like designing, development, performance, management, retention, data, and analysis on human resources for the health care sector. Health Economics and Public Policies in the field identifying with authority, administration, and organization of public health, health awareness systems, clinics, and doctor's facility systems.

Regulatory toxicology comprises the study of a toxicity profile that is compared with other known toxicants. Regulatory toxicology works as the major centre 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.

Medical toxicology is a subspecialty of medicine focusing on toxicology and providing the diagnosis, management, and prevention of poisoning and other adverse effects due to medications, occupational and environmental toxicants, and biological agents. Medical toxicologists are involved in the assessment and treatment of a wide variety of problems including acute or chronic poisoning, adverse drug reactions (ADRs), drug overdoses, envenomation, substance abuse, industrial accidents, and other chemical exposures.

Occupational Toxicology is involved with health effects from exposure to chemicals in the workplace. The objective of the occupational toxicologist is to prevent adverse health effects in workers that arise from exposures in their work environment. Occupational toxicologists assess the hazards and risks to health posed by chemicals encountered in the workplace. The risk assessments provided by occupational toxicologists are crucial for avoiding ill health linked to work.

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.

Chemical products and processes that reduce or eliminate the use or generation of hazardous substances is known as green chemistry. Green chemistry applies across the life cycle of a chemical product, as well as its style, manufacture, use, and supreme disposal. Green chemistry focuses on the environmental impact of chemistry, including technological approaches to preventing pollution and reducing the consumption of non renewable resources. It prevents pollution at the molecular level.

A gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.  Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. Future climate change and associated impacts will differ from region to region. Anticipated effects include increasing global temperatures, rising sea levels, changing precipitation, and expansion of deserts in the subtropics.

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.

Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them. Ecologists also study many kinds of environments.

Natural disaster is that the consequence once a natural hazard affects humans.  A natural hazard will hence never result in a natural cataclysm in areas without susceptibility like strong earthquakes in unoccupied areas. The term natural has consequently been uncertain as a result of the events merely don't seem to be hazards or disasters while not human participation.

Environmental Toxic substances and chemistry describes original experimental or theoretical work that considerably advances understanding within the space of environmental Toxic Substances, environmental chemistry, and hazard/risk assessment. Environmental Toxic Substances and Chemistry is knowledge domain topics that integrate the sphere of Toxic Substances within the environment; environmental, analytical, and molecular chemistry of system.

Ecology is that the study of the relationships between living organisms, together with humans, and therefore their physical environment; it seeks to grasp the important between plants and animals and the world around them. Ecologists additionally study several forms of environments.

Risk related to a well-defined situation and a recognized threat (also called hazard) is quantitatively or qualitatively determined by risk assessment.  Quantitative risk assessment needs calculations of 2 parts of risk (R): the magnitude of the potential loss (L), and therefore the chance (p) that the loss can occur.

Chemicals present in an organism such as, Pesticides is considered as bioaccumulation. Bioaccumulation happens once an organism absorbs a substance at a rate quicker than that at that the substance is lost by organic process and excretion. Biotransformation can strongly modify the bioaccumulation of chemicals in an organism. Intensive injury to organisms and declines in life populations are discovered at the side of long-run bioaccumulation and Biomagnification of persistent xenobiotic chemicals.

Blue planet on which we live is formed by the global forces of nature called oceans. They plays a major role in life-support system for Earth and a global commons that provide us with free goods and services, from the food we eat to the oxygen we breathe .The oceans additionally regulate the world climate and that they mediate temperature and drive the weather, determinative precipitation, droughts, and floods.
