Seawater quality factors

This study aims to investigate the characteristics of the salinization phenomenon in water systems and its controlling factors based on hydrogeochemical analysis, seawater-freshwater mixing model and End Members Mixing Analysis. The results revealed that seawater intrusion negatively affects strongly on surface water quality with different magnitudes, depending on seasonal variation and tidal regime.

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.

In this paper, we constructed the halophyte Mesocosm experimental group which was used as a substrate material that consisted of tidal flat and dredged sediment. Depending on whether the ingredients of vegetation and substrate material of Mesocosm, we constructed Mesocosm A (tidal flat sediment + Salicornia herbecea), Mesocosm B (only dredged sediment), Mesocosm C (dredged sediment + Salicornia herbecea).

In 1990, four of the ten leading causes of death in American women were chronic diseases directly associated with modifiable behavioral factors including physical inactivity or sedentary lifestyle. They were heart disease, certain forms of cancer (specifically, breast and colon cancers), cerebrovascular disease (hypertension and stroke), and non-insulin-dependent diabetes mellitus (NIDDM) (National Center for Health Statistics, 1993).
