The analysis of changes in water quality in a monitoring network system is important because the sources of pollution vary in time and space. This study utilized analysis of the water quality index calculation, hierarchical cluster analysis, and mapping. This was achieved by assessing the water quality parameters of the samples collected from Galma River in Zaria, Northwestern Nigeria in wet an...

Because of the rapid economic growth in China, many regions are subjected to severe particulate matter pollution. Thus, improving the methods of determining the spatiotemporal distribution and uncertainty of air pollution can provide considerable benefits when developing risk assessments and environmental policies. The uncertainty assessment methods currently in use include the sequential indic...

Road traffic in urban areas is recognized to be associated with urban mobility and public health, and it is often the main source of noise pollution. Lately, noise maps have been considered a powerful tool to estimate the population exposure to environmental noise, but they need to be validated by measured noise data. The project Dynamic Acoustic Mapping (DYNAMAP), co-funded in the framework of...

Noise mapping is an effective method of visualizing and accessing noise pollution. In this paper, a noise-mapping method based on smartphones to effectively and easily measure environmental noise is proposed. By using this method, a noise map of an entire area can be created using limited measurement data. To achieve the measurement with certain precision, a set of methods was designed to calib...

Mental acuity is essential to productivity in most professions and possibly associated with indoor air quality. Despite the empirical evidence on links between indoor air pollution and human health, the literature on the effect of indoor pollution on cognitive performance is exceptionally scarce. I examine this potential link using a sample of university final examination results from a British...

The problem of assessing the impact pollution in protected areas prompted us to apply a combined method bioindication and spatial mapping phytoplankton data from six lakes Burabay National Nature Park Northern Kazakhstan. issue monitoring planning was quite acute for this landscape-homogeneous area among Kulunda steppes. Phytoplankton each collected summer season 2019 at total 54 sampling stati...
