Pollution levels

In this study, soil samples around Nam Son municipal waste disposal site were collected and analyzed 16 typical PAHs in order to determine the pollution level for cropland and the PAHs origin in this area. To the best of our knowledge, this is the first study on organic matter pollution such as PAHs in paddy soil near the Soc Son solid waste treatment complex.

The sediment quality assessment showed that trace element concentrations were lower than the limited values in the sediment quality guideline (QCVN 43:2017/BTNMT). According to the Igeo index, the sediments were not polluted by Cu, Pb, Zn, Cr, Fe, and As but were likely polluted by Hg and Mn in some sampling sites. Therefore, it is necessary to invest the future studies to assess the Hg and Mn concentration levels in these sites to protect the marine environment.

In study "Impact of urbanization on seawater quality in Quang Ninh province" the authors use indicators to assess the level of water pollution, such as chemical and microbial pollution and measure the impact of urban factors, such as population growth, wastewater discharge and water consumption. In the survey results of seawater quality in two seasons, the rainy season and the dry season, there is a difference in some specific hydrological indicators, such as Coliform exceeding the allowable threshold in the dry season and iron and ammonium content tending to increase.

Ebook "Plants and heavy metals" focuses on the many aspects of the interaction between plants and heavy metals. Not only it describes the effects of heavy metal toxicity on the plant cell and its organs but it also examines the mechanisms that plants adopt to scavenge heavy metals at cellular, physiological, and metabolic level. Plants and Heavy Metals also analyses Hyperaccumulator plants and shows their potential role in phytoremediation technologies in light of the recent research results.

Ebook "Environmental options: Accounting for sustainability" provides not only a model at the global level, but also at the level of individual industries, and for various social groups. Of equal significance, the framework also allows international linkages to be examined. The proposed framework will serve as a common yardstick in formulating environment policy in both developed and less developed countries, setting the standard for further international cooperation.

The air pollution index (API) and the air quality index (AQI) have been commonly applied in Vietnam and abroad. These indices are aggregated from the individual indices (sub-indices), calculated from daily standards (1hr, 8hr and 24hr), or yearly standards (24hr, year), and employed for overall assessment of the level of pollution/air quality

This thesis examines the strategic and potentially legitimising nature of voluntary environmental reporting. First, the thesis examines the relationship between emission levels on the National Pollutant Inventory and the quantity of total voluntary environmental disclosures, voluntary emission disclosures and positive voluntary environmental disclosures in annual reports. Second, an examination of changes in the quantity of disclosures discussing compliance with the National Pollutant Inventory and/or disclosures concerning pollution emissions is undertaken.
