Fine particles are more dangerous than coarse particles. Apart from the size of the particles, other specific physical, chemical, and biological characteristics that can influence harmful health effects include the presence of metals, PAHs, other organic components, or certain toxins. When particulate matter is combined with other air pollutants, the individual effects of each pollutant is accumulated. In certain cases, especially for combinations of particulate matter with ozone or allergens, effects were shown to be even greater than the sum of the individual effects. When particulate matter interacts with gases, this interaction changes its composition and, therefore, its effects.
Common Hazard Symbols and their meaning There are some different dangers when handling chemicals. Hazards are different for each chemical. Some may be poisonous, cause fire easily or even explode. In order to warn each an every individual hazards chemicals use hazard symbols.  Flammable solvents Any liquid that has a flash point below 100 degrees fahrenheight (0F) or 37.8 degrees centigrade (0C) is a Flammable liquid.
Air Pollution; from lung to Heart There are so many types of pollution present all around the world affecting a number of lives everywhere. Examples of pollution are air pollution, soil pollution, water pollution and noise pollution. In case of air pollution, it can be defined when harmful and some radioactive substances that mix with air and pollute it. When a person inhales that air, it directly reaches the lungs and make the person sick. One of those harmful gases contain carbon dioxide that is warming the earth at a large extent.
The Factors That Affect Climate Change There are many factors that have a large impact on climate change, but the one we decided to address is air quality and air pollution. Air pollution is one of the few types of pollution. This one specifically refers to pollution in a sense of the contamination of the air by smoke and harmful gasses. There are two main types of air quality, indoor and outdoor. The main factors that affect air quality are as follows: The main factors affecting outdoor air quality: Topography - Concentrations of pollutants can be greater in valleys than for areas of higher ground.
Continuous haze adversely affects the health of any group no matter young and old. These adverse effects are at high risk, such as dealing with problems coughing, shortness of breath difficulty breathing, chest pain, skin will itch, runny nose and so on. According Director General of Health, Datuk Dr Noor Hisham Abdullah, said there was an increase of more than one hundred percent of asthma since the haze crisis. In addition, the increase also occurred in upper respiratory tract infections, namely in Johor at 38.5 per cent and 20.7 per cent of Malacca. Therefore, Dr Noor Hisham reminded the public to reduce outdoor activities or use masks when outside the home.
Air pollution is said to be one of the major environmental problems that is present in both developed and developing countries. Nations have been trying to reduce the amount of the air pollutants; nevertheless, it is an inevitable problem in a world where people are highly dependent on industries. Air pollution is the contamination of air by smoke and harmful gases, mainly oxides of carbon, sulfur, and nitrogen. This takes a huge toll on human health, and the surrounding environment. Some pollutants that contribute to air pollution are: carbon dioxide, nitrogen dioxide and sulfur dioxide.
Global warming is one of the factors created by pollution and other variants. In the world there are two types of pollution and one connected outcome one type of pollution is air pollution, another is water pollution, and the outcome is global warming. Air pollution has the most harmful effects on the environment with support by people that believe in air pollution and opposed by those who don’t. Air contamination is divided into two broad categories: primary and secondary. “Primary
The releases these plants produce are amongst the highest portion on the earth and contribute essentially to the sum poisonous gasses that pollute air. Nevertheless, technological change lately has seen production of more machines, weapons and autos. In spite of the fact that unfriendly population of environment because of expanded creation in the production industries, weapons testing and high utilization of vehicles and autos. Air toxic waste, water and noise contamination are the key parts that has been persistently polluted environment due to the utilization of technology. Outflow of vast amount of gasses such as CO2 released by the processing industries results air contamination, which has corrupted environment.
Particulate matters are the most dangerous to human health. This is because the sizes of particles are directly linked to potential of health problems as it is within the respirable range. The respirable range is a particle with a diameter of 10 micrometers or smaller that does not exceed more than PM0.1 can easily pass through human respiratory system and deposit there. Therefore, once it is inhaled it can affect the heart and lungs, which lead to serious health effects especially to those who have asthma. Thus, with this air quality monitoring system human can prevent health problems.
Similarly, it has an annual average daily solar radiation of about 5.25KW/m2/day, varying between about 3.5KW/m2/day at the Northern boundary. Nigeria receives about 4.851x1012KWh of energy per day from the sun. This is equivalent to about 1.082 million tons of oil equivalent per day and is about four thousand times the current daily crude oil reduction, and about 13,000 times that of natural gas daily production based on energy unit. This huge energy resource from the sun is available for about 26% only of the day. According to Garba and Bashir (2002), the country is also experiencing some cold and dusty atmosphere during the harmattan, in its Northern part, for a period of about four months (November-February) annually.
