Theory of Environmental Pollution is one among them. In this article, we have thoroughly discussed the types, causes and impacts of different pollutions affecting humankind. Kidney problems, irritation in eyes, nose and throat, asthma, hypertension and carcinogenic effects on lungs.
Pollution touches all parts of the planet. It is affecting our health through the food we eat, the water we drink and the air we breathe. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources to support global production and consumption and which impact the environment.
Study Session 7 Pollution: Types, Sources and Characteristics
Environmental pollution or simply pollution refers to undesirable changes occurring in the physical, chemical, and biological composition of natural environment consisting of air, water, and soil. Pollution also means the presence of harmful pollutants in an environment that makes this environment unhealthy to live in. Natural environment has an inbuilt capacity to replenish the losses or reduction in its constituents to restore it as sustainable and healthy as required. Ever expanding population and evolution of man into modern homo sapiens have led to rapid urbanization, industrialization and unprecedented rise in human habitations. All these human endeavors have, in turn, virtually perpetuated deforestation, loss of habitats for flora and fauna, depletion of natural resources at a large scale over the last couple of centuries, which have told upon the inherent resilience of the natural environment. As a result, natural environment continues to be undesirably polluted. A pollutant is defined as any form of energy or matter or action that causes imbalance or disequilibrium in the required composition of natural objects such as air, water, etc.
When many of us think of pollution, images of smoggy cities and litter-infested oceans come to mind. While littering and gasoline-fueled cars are a major contributor to pollution, there are many other influences that are important to be aware of. Essentially, pollution occurs when substances are introduced to the environment that have harmful effects, damaging the quality of land, water, and air. The cause is the accumulation of solid and liquid waste materials that contaminate groundwater and soil. These waste materials are often referred to as municipal solid waste MSW , which includes both hazardous and non-hazardous waste. When waste is deposited onto an area of land, the permeability of the soil formations below the waste can increase or reduce the risk of land pollution.
Environmental pollution is reaching worrying proportions worldwide. Urbanization and industrialization along with economic development have led to increase in energy consumption and waste discharges. The global environmental pollution, including greenhouse gas emissions and acid deposition, as well as water pollution and waste management is considered as international public health problems, which should be investigated from multiple perspectives including social, economic, legislation, and environmental engineering systems, as well as lifestyle habits helping health promotion and strengthening environmental systems to resist contamination [ 1 — 3 ]. Environmental pollutants have various adverse health effects from early life some of the most important harmful effects are perinatal disorders, infant mortality, respiratory disorders, allergy, malignancies, cardiovascular disorders, increase in stress oxidative, endothelial dysfunction, mental disorders, and various other harmful effects [ 4 , 5 ]. Though, short-term effects of environmental pollutants are usually highlighted, wide range of hazards of air pollution from early life and their possible implication on chronic non-communicable diseases of adulthood should be underscored. Numerous studies have exposed that environmental particulate exposure has been linked to increased risk of morbidity and mortality from many diseases, organ disturbances, cancers, and other chronic diseases [ 6 , 7 ].
Towards a pollution-free planet
Subscription price Impact factor Clarivate Analytics 0. It focuses on ground-breaking research in the science of environmental pollution, at the early scientific stage. The objectives of IJEP are to establish an effective channel of communication between policy makers, government agencies academics and research institutions and persons concerned with the complex issues of environment and pollution, and to provide a forum for them to disseminate information and to learn from each other s work. The international dimension is emphasised in order to overcome cultural and national barriers and to meet the needs of accelerating technological change and changes in the global economy. Professionals, academics, researchers and policy makers. Contents IJEP publishes original and review papers, technical reports, case studies, conference reports, management reports, book reviews, and notes, commentaries and news.
The environmental pollution threat increases if the organic substances that have been released into the environment are persistent (Persistent Organic. Pollutants.
Environmental Studies - Pollution and Control
You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food.
Сьюзан трудно было поверить в такое удачное совпадение. - Его погубило слабое сердце - вот так. Слишком уж удобная версия.
Поэтому отключение представляло собой сложную серию подтверждений и протоколов, гораздо более сложную, чем запуск ядерной ракеты с подводной лодки. - У нас есть время, но только если мы поспешим, - сказал Джабба. - Отключение вручную займет минут тридцать.
- Я не могу выйти за тебя замуж. - Она отвернулась. Ее плечи подрагивали. Она закрыла лицо руками.
Понятия не имею. Я побежал позвонить в полицию. Когда я вернулся, немца уже не .
Положение оказалось куда серьезнее, чем предполагала Сьюзан.
