The GLP regulations have developed from rules on how to exactly document the planning, conduct and reporting of toxicity studies to a quality system for the management of a multitude of study types, from the simple determination of a physical/chemical parameter to the most complex field tests or ecotoxicology studies. At the same time the term "Good Laboratory Practice" has become somewhat of a slogan with the aim to characterise any reliably conducted laboratory work.

In porous aquifers, the central-to-sea cross-section highlights meteoric water dominance from rain and surface sources. Groundwater undergoes exchange-absorption with silicate minerals, enriching Ca2+ and Mg2+ (reducing Na+). Seaward, dissolution and leaching of salts in marine-origin sediments (mQ2, mQ13, mQ12-3, and mN22) prevail. The results of this paper provide necessary information for the effective management of groundwater quality.

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.
