Abstract:
According to present status in China to controll indoor air pollution should go on from six aspects that are temperature, relative humidity, ventilation, selecting material, purification technology and plant purification. The higher the temperature and relative humidity is, the easier indoor air pollutants are released. Ventilation and selecting material is an efficient way to controll indoor air pollution. Plant purification is a good way to improve the living environment.

Abstract:
Pollution is increasing very effectively in the world. It must be reduced the present pollution levels by the deadline even though the long-term solution to the pollution problem is to identify and reduce pollution sources. The use of air purifiers is the most effective method of reducing pollution. Regular interior air purifiers, however, are little, low-power gadgets that lack the necessary filtering capacity for outdoor environments. Additionally, there is a problem with outdoor machines' power supplies. Therefore, it has created a solar outdoor air purifier that is energy independent and b

Abstract:
The article highlights the problem of air pollution in large cities. Sources of pollution and the most common pollutants have been identified. Examples of leading countries with the dirtiest air are given. The estimated indicators for the risks of disease and mortality are considered. The main factors causing air pollution have been identified. Ways to solve this problem using modern technologies are proposed. Analyzed are modern facilities in which innovative methods of combating air pollution are applied, and their implementation in real and conceptual design. The conclusion is drawn on the

Abstract: Degradation of air quality, like climate change and global warming, has become an all-encompassing existential hazard to humanity and natural life. Exposure to severely polluted air on a regular basis causes pulmonary disorders and contributes to severe allergies and asthma. According to studies, more than 10 million people die each year as a result of irregularities produced directly or indirectly by air pollution. The work of Lelieveld et al. [1] sheds light on the gravity of the problem. It is estimated that by 2050, the worldwide premature mortality from air pollution will exceed

Abstract:
Indoor air pollution is injurious to human health, even worse than outdoor air pollution. However, there is a lack of empirical evidence using large samples in developing countries regarding whether indoor air purification can improve human health by reducing indoor air pollutants. Using the data from the China Health and Nutrition Survey in 2015, this study analyzes the relationship between indoor air purification and residents’ self-rated health. We apply the generalized ordered logit model and find that indoor air purification has a significantly positive effect on residents’ self-rated hea

Abstract:
Household air pollution mainly falls into five categories: chemical pollution, radiant pollution, physical pollution, biological pollution and air particulate pollution. They do a great damage to human health. The plant purification is drawing wide attention, because it is economical, effective and it also has its ecological function and aesthetic values. Improper methods will cause the second-time pollution, and can hinder the growth of the plants. The core for plant purification is to choose the proper plants and scientific arrangement. Plants were chosen according to the function of the roo

The self-purification capacity is an important indicator for a healthy river. Organic and inorganic pollutants from various pollutant sources, both point sources, and non-point sources, in most rivers in Banjar Regency, cause a decrease in river water quality. This study aims to identify the distribution of river water quality pollution in Banjar Regency as the upstream of the Martapura River and determine the point of self-purification.

Abstract:
Air purifiers should pay much attention to hospital-associated infections, but the role of a single air purifier is limited. The goal of this study was to evaluate the effectiveness of the combined application of the nonequilibrium positive and negative oxygen ion purifier (PNOI) and the high-efficiency particulate air filter (HEPA) on a complex, polluted environment. Two of the better performing purifiers were selected before the study. The efficacy of their use alone and in combination for purification of cigarette particulate matter (PM), Staphylococcus albicans, and influenza virus were th
