Health impacts of air pollution

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise. The particulate forms are: PM10 and PM2. Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence strongly the process of photosynthesis which rate declines sharply.

Environmental pollution and its impact on human health

Human health is closely related to his environment. In general, polluted air is considered one of the major factors leading to many diseases such as cardiovascular and respiratory disease and lung cancer for the people. Besides, air pollution adversely affects the animals and deteriorates the plant environment. The overarching objective of this review is to explore the previous researches regarding the causes and sources of air pollution, how to control it and its detrimental effects on human health. The definition of air pollution and its sources were introduced extensively. Major air pollutants and their noxious effects were detailed. Detrimental impacts of air pollution on human health and well-being were also presented.

Air pollution is now the biggest environmental risk for early death, responsible for more than 6 million premature deaths each year from heart attacks, strokes, diabetes and respiratory diseases. Children, the elderly, people with existing diseases, and minority and low-income communities are particularly vulnerable to adverse health outcomes and economic impacts, such as missed work days, from exposure to air pollution. Research suggests that long term exposure to some pollutants increases the risk of emphysema more than smoking a pack of cigarettes a day. And recent studies show air pollution can impact mental health , worker productivity and even stock market performance. What we typically think of as "air pollution" is actually a mixture of small particles, including the below. Particulate matter PM is made up of small airborne particles like dust, soot and drops of liquids. The majority of PM in urban areas is formed directly from burning of fossil fuels by power plants, automobiles, non-road equipment and industrial facilities.

Environmental and Health Impacts of Air Pollution: A Review

Metrics details. Traffic-related air pollution TRAP is one of the major sources of exposure in urban areas and has been associated with a wide range of adverse human health effects. The objective of this scoping review is to develop an evidence map of the epidemiological literature of the human health effects of exposure to TRAP, to support future reviews and assessments by Health Canada. DistillerSR will be used to manage the review process. Two reviewers will independently screen the studies in a two-part process title and abstract; full text for eligibility.

Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. It has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution. According to the World Health Organization, six major air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Long and short term exposure to air suspended toxicants has a different toxicological impact on human including respiratory and cardiovascular diseases, neuropsychiatric complications, the eyes irritation, skin diseases, and long-term chronic diseases such as cancer. Several reports have revealed the direct association between exposure to the poor air quality and increasing rate of morbidity and mortality mostly due to cardiovascular and respiratory diseases.

A major study on urban pollution carried out in cities worldwide has confirmed the fear that air pollution impacts on human health in the short term and is directly linked to the deaths of elderly people and those already suffering from illness on a daily basis. The study, performed by an international team of 50 scientists and published in the specialist New England Journal of Medicine , gathers data on cities in 24 countries, including Mexico City, New York City, London and Madrid. The research focuses on two kinds of ambient suspended particles , emitted mainly from car exhausts: PM 10 , able to penetrate lungs; and PM 2. The authors of this macro study link the daily increase in these particles to the increase in daily mortality for all causes, and an increase in death due to respiratory and cardiovascular problems.

Ground-level ozone is formed when volatile organic compounds VOCs and oxides of nitrogen NOx react with the sun's ultraviolet rays. The primary source of VOCs and NOx is mobile sources, including cars, trucks, buses, construction equipment and agricultural equipment. Ground-level ozone reaches its highest level during the afternoon and early evening hours.

В голове у нее стучало. Повернувшись, она увидела, как за стеной, в шифровалке, Чатрукьян что-то говорит Хейлу. Понятно, домой он так и не ушел и теперь в панике пытается что-то внушить Хейлу. Она понимала, что это больше не имеет значения: Хейл и без того знал все, что можно было знать.

Откуда-то сверху накатывали приглушенные волны классической музыки. Бранденбургский концерт, - подумал Беккер.  - Номер четыре. Они со Сьюзан слушали этот концерт в прошлом году в университете в исполнении оркестра Академии Святого Мартина. Ему вдруг страшно захотелось увидеть ее - сейчас .

Все остальные встретили слова Беккера недоуменным молчанием. - Элементы! - повторил Беккер.  - Периодическая таблица. Химические элементы. Видел ли кто-нибудь из вас фильм Толстый и тонкий о Манхэттенском проекте.

Quality of air, quality of life

 А как же Сьюзан? - Хейл запнулся.  - Если вы позвоните, она умрет. Стратмора это не поколебало. - Я готов рискнуть. - Чепуха. Вы жаждете обладать ею еще сильнее, чем Цифровой крепостью.

Это. - подумала она удивленно и с облегчением и попыталась выскользнуть из-под. - Милый, - глухо прошептала.  - Позволь, я переберусь наверх.

 Конечно. Договорились. Девушка покачала головой. - Как бы я хотела сказать. - Миллион песет? - предложил Беккер.

Огромный лист гофрированного металла слетел с капота автомобиля и пролетел прямо у него над головой. С гулко стучащим сердцем Беккер надавил на газ и исчез в темноте. ГЛАВА 84 Джабба вздохнул с облегчением, припаяв последний контакт. Выключив паяльник, он отложил в сторону фонарик и некоторое время отдыхал, лежа под большим стационарным компьютером. Затекшая шея причиняла ему сильную боль.

Повсюду в старинных домах отворялись ворота, и люди целыми семьями выходили на улицы. Подобно крови, бегущей по жилам старого квартала Санта-Крус, они устремлялись к сердцу народа, его истории, к своему Богу, своему собору и алтарю. Где-то в уголке сознания Беккера звонили колокола. Я не умер.

И опять за дверью что-то как будто включилось. Она услышала, что в кабине работает вентиляция. Лифт. Почему же не открывается дверца.

Один голос был резкий, сердитый. Похоже, он принадлежал Филу Чатрукьяну. - Ты мне не веришь. Мужчины начали спорить.

    Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight.
